Printed great on Creality Cr10 S Pro using wood filament. Had to print the support rod vertical with a base but otherwise super easy at 120% scale!

How are people printing this with no support? I started with the Jaw and got spaghetti. Using CURA, imported the file as is. .2mm, 20% infill. Ender 3. Looks like the Skull will need support as well. The imports into Cura look exactly like the pics in the model. Thanks!

Printing now on Anet A6. 06mm nozzle, 0.3mm height, 20% infill, wood PLA. Upright, no support. Gonna be interesting :-)

Is this skull compatible with the full T Rex Skeleton? I just print first part of the skull, but I find there is a full skeleton.

No, its not. The full T-Rex skeleton has the neck joint at the back of the skull not in the roof of the mouth as seen in this model.

Thank you for this thing! Thumbs up to you!

I've printed this at normal file size and the only issue I had was the rod (printed upright) being somewhat small in diameter. That one was printed on Monoprice Ultimate (Wanhao D6) at .20 resolution and 25% infill with supports on the lower jaw but nothing else as far as supports and/or rafts/brims.
I just completed the upper skull at 2x scale on the Monoprice Mk.1 Pro. (Wanhao D9 /CR10 clone) It took the better part of a spool of PLA and took ~44 hours. The thing is HUGE!!! Again, .20 resolution and IIRC 20% infill. I also, added a brim to help the skull print stick to the build plate as the surface area is fairly small given the high upright print orientation.. I'll be starting the lower jaw to match on Monday morning.

This is an awesome design.

Is there any reason why the rod can't be split in half, printed in two pieces laying flat, then glued back together? I just did a lamp with a small rod like this and it came out perfect and glued back together without being able to see the seam at all. I could be wrong; just food for thought.

Might be the creator him/herself. Let him/her report it to etsy... With 3d print, I guess this is impossible to track anymore.

Printing scaled up to 150%

.2 layer height and 15% infill.

do you use supports?

No supports needed.

I'm printing on a CR-10S too, did you have to use any supports? I have under extrusion on the nose of the skull.

No supports. Printed 3 in total and had no issues at all.

did you do any sanding or clean up?

Nope.... Came out clean. I used amz3d for the first 2 small prints and cctree for this one.

Couple of tips I thought I might share:

Regarding the rod, unlike the other parts, I repositioned this to be upright while being printed to make for a nicer surface.
Also it didnt fit the holes, so it would wiggle once put together.

However, printing it upright would take 4 times longer as its small and therefore cant print too fast due to the PLA cooling time.

The solution for the two issues for me was:

  1. Increase the size by 5% (it made for a perfect fit)
  2. Print upright in vase mode

In my case I increased the size of all 3 axes by 5% as I also wanted the rod to be a little taller, you can omit the height and just increase the two other axes to achieve the proper circumference.

Tip for printing the base:
I did a multiprocess print where the vertical parts were printed at .2mm and the faceted section was printed at .1mm.

In regards of infill I set it to 5% only, but a few layers from the top I increased it to 30% to ensure a smooth top solid layer.
For the section printed in .1mm I set the infill to print for every 3rd layer only (.3mm) which increased printing speed.

Speed settings were 3600mm/s with 60% outline underspeed.

The full print and in all has taken about 14 hrs and was done on my Creality CR-10 (aka Afinibot A31)

Thx to the author for a great model that looks super cool and prints so easily. :-)

Hi can you share the setting for Cura please.Thanks.

Thanks for the info! What slicer are you using?

I'm using S3D :-)

I just printed this T-REX Skull. I am new at 3D Printing and really love it. I have 3 family members with multiple printers. 3 of us have purchased the new Mark 3 Prusa. Just wanted to say that this was a very easy print file, and it came out perfect. Only 4 parts to print. Thank you for being so through with making this design. I am adding a photo of my final print.

Just printed this T-REX Skull model and put an LED light base under it! It looks AWESOME! Check out my time lapse video of the print:

Timelapse Video: https://youtu.be/QOrLKlxMdck

Printer settings can be found in the description of the YouTube video! Thanks for a great model Makerbot!

I wouldn't normally pick up on grammar / spelling etc, but seeing as this is a teaching resource with scientific underpinning -- species names are always in lower case i.e. the base should read "Tyrannosaurus rex". It should also be in italics, especially throughout the teaching materials (even when shortened to 'T. rex').

Great project! I printed it on a Monoprice Select Mini Ver 2 using CURA 3.2.1, at recommended (default) settings except I used a raft for both the skull and mandible. No problems.

Hi. How would I find the default (recommended) settings for this print?

Materials Needed
One computer with connection to the Internet; one MakerBot Replicator 2 Desktop 3D Printer.
The T-Rex Skull 3D files.
Paper, pencils, poster boards, markers.
*One 3D printer

Top of skull turned out great. Used minimum layer height on a monoprice mini.

The second jaw turned out worse even at higher resolution.

3rd print turned out even worse. Printed 50mm/s. 0.15 resolution. 40% infill. Everything printed well except for the teeth.

I can't get the lower jaw teeth to print properly. The top skull teeth turned out well with the same settings. I just started a third print of the lower jaw. Used 40% infill, slowed the speed and printing in 0.15 resolution. Any ideas other than getting it a set of dentures?

hello is it possible to have the base without "Tyrannosaurus Rex" ??
thank you

This model is fantastic. I burned out a nozzle printing it in glow-in-the-dark filament. Great work! My only suggestion would be to split the name plate on the base to a separate model so it could be printed in a different color (brown base and silver plate in my case) so it'd really stand out. Thanks!

incredible model) What printer did you use?

Comments deleted.

I printed this model, very nice and no supports needed. Very impress

Comments deleted.

Printed on a CR-10 at 67% scale, .15mm resolution, 10% infill and a raft on PEI. No supports needed. Took about 4 hours and it looks great!

You printed this with no supports? Wow. Did you maintain the same part rotation/placements as they come in the STL?

Yes, as-is (added a brim), and it printed very well to my surprise.

I should have trusted the STL (and read the comments!). I started with the upper jaw and it didn't seem right printing "on end" so I went and rotated it more flat. I think that was a mistake, but I don't know yet (half way through the print). The teeth are touching the bed and I suspect they're going to break. I also had to use a ton of supports. I'm considering starting over, but I'm 4 hours in. Meh, I'll let it finish. It might be OK. But had I printed it as is, it would be almost half the build time and no supports.

I was impatient. My kid wanted it and I did it without reading (or thinking).

I am really struggling with this print.

The skull, jaw and base all have come out perfectly.

But i can't seem to print the rod, it always lifts up about 10mins into the print. I have tried a whole range of settings. Any suggestions?

Comments deleted.

there are no printer settings with your video

Thanks for pointing that out, I had forgotten to put them in. Just updated the description, so they should be there now! Let me know if you have any other specific print settings questions! Really awesome print to make!

Don't see any print settings.

Hi NormL, the print settings are in the description of the youtube video, but I will also provide them below:
Print Settings:
Layer Height = 0.2mm
Infill Density = 20%
Printing Temp = 200 deg C
Build Plate Temp = 60 deg C
Print Speed = 60mm/s
Outer Wall Speed = 30mm/s

Thank you so much. This is attempt #8 to print the lower jaw. I recently discovered I have under extrusion issue. Have calibrated extruder and set flow rate to 112% in Cura. Am printing a bit slower at 50mm/s. Have gone thru almost a whole roll of PLA on this print! Most of it prints fine, except for the teeth, due to the under extrusion issue. Will post a pic once I get it to print properly. Kind of obsessing over it. lol

No problem, I hope that helps! I would love to see the photo of yours once it is done! Best of luck!

Ran out of yellow PLA. You can see the yellow under extrusion. The red jaw was printed at 205 degrees, 50mm/s and flow set to 140%. The teeth are acceptable. I will paint it with my new airbrush (once I figure it out). NOTE: Both red and yellow are AMZ3D PLA. The yellow extruded 93mm/100mm and the red extruded 90mm/100mm. My Anet A8 adjusted at 118% for 100mm of filament. Printed one at 130% in Cura and teeth were still not nice. When I sliced at 140% and 205 degrees, the final result was better. I will be upgrading to a bowden extruder once I get all the parts for it. The we start back at square one (learning curve). Anyhow, I am glad I got a print I can paint and display.

I am not familiar with AMZ3D filament, I always use https://amzn.to/2LNTt8A because the quality always comes out great and is consistent for different print settings.

Thanks for this beautiful model. It looks amazing on my desk

I was able to download all the files and print 2 of these. However, I am trying to make another one and now the file is saying that the 3 of the part are to big. I can not even good in and scale it down. Is there an updated file that you put back out.

I printed 2 of these... one at 50% and one at 66%.
I did not use a raft or any supports.
PLA 190 / 50 and printed very slowly over night.
(have glass on the bed and used hairspray)
Cura 15.04.6 - 0.175 on the small one and 0.13125 on the larger one.

I keep having issues with the jaw, there's a gap in the print and even breaks the supports - it's close to the front right. I'm printing on a simple M3D at .69 the size XYZ (aka a tad smaller to fit the plate), PLA but set at tad higher temp due to the slippage off the plate everyone else was experiencing. I have the detail set to high with webbing

Now the jaw (front right side) keeps missing a vital spot with the setup as it comes in the file package - there is a build up on the "lip" and the nozzle starts skipping over it like a speed bump. I tried slowly amending/filing it during print, but to no effect. There is a gap that jeopardizes the overall print :\

What to do? May have to print in another position..?

I recommend a raft for the skull (top) since there's such a small surface area for adhesion. Mine fell off the heated bed at around 95%. I was able to measure how much printed, re-print the remaining snout and front teeth, and superglue it together. It was a headache that a small raft probably could have prevented.

Other than the adhesion issue, no supports were necessary for the skull on my printer (Wanhao i3 V2.1 / Maker Select V2.1). The jaw needed supports.

This turned out great on my Flashforge Creator Pro. I printed it at 60% of the original size, with rafts, but no supports. I used the Flashprint slicer's default settings for PLA. The first time I printed the base, the raft was difficult to remove, so I reprinted without the raft. That worked much better.

Great model

I would like to print it. I've just mounted a fan.

Can I print this model with ABS, without support and without FAN ?

The first tries with fan were worse than with no fan (less strong model, better for bridge etc.)

in general I find ABS does not print fine details as well as PLA.

Not even close IMO... I use ABS for structural parts a lot, tried many many times to get good details on models and wasted a tone of ABS

Also, you should NEVER use a fan when printing ABS, that's a PLA only thing.....
Layer adhesion with ABS requires the heat from the melted extrusion to partly melt the last layer... if you have a cooling fan you just cant get that to work right.

Wrong , you have to use fan WITH heated chamber for overhangs, bridges and small details, or do hovering maneuver to let the layers cool down slightly under ABS glass temperature.

If you just print out the head it makes a good back scratcher

i printed with PLA, at 0.2mm
i used supports just in case the model would tip over. but supports are a pain to get them off. never the less great quality.
took me 5 hours for the bottem part and 12 hours for the upper part

Comments deleted.

I made 2.

one PLA, one ABS. both of them are very well.
0.1 or 0.2. no support. amazing model.

how long should this take to print

Comments deleted.

Stupid question. The flat on the back of the skull and the flat on the back of the jaw are required? Or will they go away if I print with supports on top of rafts or some such?

This is an amazing print. I printed the skull with no supports, other than the backs of the front teeth it looks wonderful. I printed the object including the jaw with kisslicer free. I thought the jaw needed supports. I used an XY gap of 0.5mm, a z gap of zero mm, Z band is 2m, support flow was 0.60. Support quality was "fine". The support came off cleanly, perhaps there is a tiny bit of roughness but you can't tell unless you feel for it. I printed using transparent ABS, it looks quite bone like. The jaw and skull were printed on a delta using an 8-12 circle brim to help adhesion, hair spray on glass and a build plate temperature of 110C. Extruder temp was 250C for first layer then 240C for the rest of the print. I also used 8.25mm retraction and 3m hop so that the head would not run into the print when moving. Even on the delta this is a high thing with a small base so I didn't want to accidentally run into it and knock it over,

When the mount is finished I will post a make. I read the lesson plan to my wife who is an elementary school teacher. She was very appreciative.

Im using an Anet A8. Can someone tell me what works best as far as supports go? Every time I use supports they stick to the model too much and make it not look as good in the end after breaking them off.

Well, I have found that different slicers do supports really differently. Cura linear supports break off, but scar. Cura square supports are so strong I have broken prints trying to get them off. The slicers I mention below are free or were free with the versions I am using.
craftware supports are good - and the best part is that you can put supports just where you want to put them. They come off between cura square and cura linear.

I did supports for the lower jaw, automatically using kisslicer. I mentioned the exact settings in my previous message, I had supports stuck in the fine detail at the sides of the jaw, as well as under the long part of the jaw. I removed them with a fingernail or a print removal spatula. I can't tell where they were. The bottom of the jaw was slightly rough to the touch but not to look at. The things that needed to be supported were. These are, by far, the best supports I have ever used, and I am not using the pro version of kisslicer.

I've tried to print the skull portion twice now and each time, towards the last 30 minutes of the print it breaks off the build plate. It's enormously frustrating; the second time I printed a raft and it got a little further but still broke off at 97%. I'm printing with PLA at 50mm/s with a heated bed temp of 65C, does anyone have any suggestions as to why this would be?

I printed it on a Delta, which does not move the plate. Try a much larger brim. Also, I find that 65 is too hot on my printers for PLA, but it depends on what the actual surface temperature for the print is. I print at a measured 60 with PLA on glass or either cold or 60 on blue tape.

made it at 50% smaller. jaw cracked now every time i make it, it breaks

made it at 50% smaller. jaw cracked now every time i make it, it breaks

I have replicated the same issue - it's close to the front right. I'm printing on a simple M3D at .69 the size XYZ (aka a tad smaller to fit the plate), PLA but set at tad higher temp due to the slippage off the plate everyone else was experiencing. I have the detail set to high with webbing

Now the jaw (front right side) keeps missing a vital spot with the setup as it comes in the file package - there is a build up on the "lip" and the nozzle starts skipping over it like a speed bump. I tried slowly amending/filing it during print, but to no effect. There is a gap that jeopardizes the overall print :\

What to do?

Is this the same head as the full version or do I need to reprint the head if I purchase the full t-rex

You have to print the full trex because it does not connect

Did any body do the whole model? Do you purchase STL files or is it something else?

Doh!!!! Only 10 minutes left on a 5 hour print of the skull and it broke off my plate. I've slowed the speeds way down and it's going to take 15 hours to print. I hope it works this time.

No luck. It actually broke off even earlier this time.

Make sure the nozzle is close enough to the bed where sliding a piece of paper under it on the 4 corners catches the paper just enough without tearing it. Do it about an inch in from the corners, not exactly in the corners. You need it close enough to squish the filament onto the bed to make good adhesion. Try turning your first layer temp up about 10-15 more degrees so it really sticks.

I have prints that stick so well that I don't think I'll ever get them off at times. I print onto blue tape wiped with alcohol.
Good luck!!

I have to use a knife or screw driver to remove my prints. I'm using 3D Eez. I changed the infill from 80% to 40% and it succeeded. Only took about 4-5 tries. :)

This was my first print after the print test part on my Da Vinci Pro and it turned out great. The lower jaw came loose the first time I ran it but with a little more stick glue the second try was perfect.

Do you have any pictures or videos of this print?

Ive been having issues with the bottom jaw still lol what were your settings at?

I printed it in abs because that's all I had I was set 210 on the extruder and 90 on the bed. I used blue painters tape on the bed and a lot of glue stick on that. I also slowed the printer down to a crawl as time did not matter to me and the second time worked great. First time was with the settings that the slicer threw in there. Also did not use glue the first time. Hope this helps you.

could you guys redesign the base of this print? it's overly sized and uses way to much material for what it does, it could be designed a lot better and not waste so much filament. maybe some sort of T shape, with 2 short legs and 1 long leg, and the name plate could be put on the long leg.

This was our first large print on the ideaPrinter F100L using eSun's 3mm Orange PLA Filament. Came out to be 1.5ft long with amazing detail and quality. Check out our timelapse video here:

Online Store & Educational Platform for 3D Printing

How did you embed this video so that it plays right from thingiverse?

side question: how did you get your time lapse to be so smooth?

Have your camera take more pictures so you can render out with a higher FPS

Higher FPS sounds too easy. I've been using a GoPro and just letting the GoPro Studio render the movie. I'll take a look at increasing the FPS. Thanks!

Thanks! I shot it on the Panasonic GH4 and stitched all the pictures together in Adobe Premiere CC. I made each image 2 frames long so it gives it a smoother motion.

I would love to tinker the base to make the name plate separate... print the base in wood pla with the plate in brass pla

This is a very nice model indeed. Add me to the list of those who would buy the full model in a heartbeat if it included STL files.

Very good model and print perfectly even without support!

I printed this on my Up! Mini 3D Printer in a lime green colour. I printed with an infill termed 'Big Hole,' and added support at 45 degrees. I probably could have used less although I didn't want to take the risk. I recommend finishing the jaw and skull teeth sections with a rotary tool such as a Dremel, just to remove any flaws. Overall, it turned out great but was quite a drain on plastic - using 61 grams for just the skull component alone. This being said, great job Makerbot!

I printed the T-Rex over this past weekend for my grandson using glow in the dark filament for the skull and everything printed perfect! Thank You for the file. you did a great job.

On things such as this, can you arrange the objects around the platform to all get made in one print or does one have to print them one at a time in separate jobs?

Depends on the size of your printer, you should always be able to print them all at once if you like. Though you take a risk in doing so as the printer sees them all as one print, so if something happen to one piece that caused you to stop, they are all ruined. I believe its considered best practice to print one at a time to avoid such an issue, though that's up to you and how reliable your printer is.

Just finished top and bottom half. No major issues, Printed on makerbot 5th gen. Default "fine" settings.

I tried printing the skull twice with no support, as was suggested, and the print was knocked off both times at about 25% completion. Just finishing one with raft and support and its working well.

Printed on my fabtotum, pla black, 210 degrees c, .10mm layer height

I am trying to print this on a makerbot replicator - V 5 brand new with newest software. I am having all sorts of issues with the material hardening before it gets to the object - specifically for the teeth. How did those of you successful with this model orient it? I tried on the top of the head - no luck, teeth down - no luck. how did you guys successfully orient and print it?

I used the stl orientation, no supports 40mm/s , 33% infill and the above settings, i used kisslicer and it came out great

What fill would you recommend I use in order to ensure a great looking print?

33% but I think you can go much lower

What color filament do you use to have it the color in the main picture? Is that warm gray?

Nope, pla black

I love the lesson plan almost as much as the model! Fantastic for science lovers.

This has been one of the largest prints I've ever done, but one of the most beautiful. I'd love to do the entire skeleton but I, unfortunately, don't have a Makerbot :( Thanks for posting though!

Did you use supports to print this as well as what thickness and fill did you print the skull at?

No supports are needed for either of the prints...I used 40% infill and .2 layer height on my Printrbot metal with PLA. It took about 5 to 6 hours, but came out beautifully.

So do I print it in the orientation it pops into dura on?

The skull may print upright without supports perfectly...so, yes

Working on the skull now, the jaw looks amazing. finished it at about 2:00AM it is beautiful.

are the makerbot people going to make the whole skeleton able to print with other printers i bought it to only realize i cant print without there printer does anyone know why not just sell the 3d model

I'm finding it very difficult to print the jaw. After many failures, I realize that the extending tip on the base is curling up, and the nozzle is knocking one of the jaw halves off the base each time it reaches a certain height. I'm continuing to try various heats, fan, infills, etc to minimize/avoid the curl.

Anyone else seeing this? Anyone else have a fix? On a Flashforge Dreamer, using the right extruder (which may not get as much cooling as the left).

im using a ctc very similair doing the jaw its at 93% print it with support at 50 degree angle tollerance, print on blue tape with colorfabb pla at 0.2 55c bed at 190c use ALOT of glue stick and make sure that you level the bed properly and print at around 40 mm's and slow down the first layer if you have updated to sailfish which i highly recommend

same here. the jaw keep on failing... I tried to orient it vertically but it still fail... I may need to up the temperature to 200+...

Can't get the Skull to print... I got the jaw, rod, and base to print but the skulls first 2 or three layers never touch (excluding the raft). I have a Duplicator 4s and and printing through Replicator G, note that the distance from the layers are about 1-2 cm off? I need help please, and fast... I have a client on the line for this, thank you.

Its your slicer settings try adjust the model Z height or just buy a copy of Simplify3D

My Creator Pro printed this with amazing results. Even the teeth where perfect.

Great test piece for new printers after you've got everything tuned. . . . .Details are outstanding. Thank you for sharing!

Printed on a Makerbot Replicator 5th gen, standard settings. Everything looks great except the teeth on the lower jaw came out a little patchy. Anyone have any suggestions for fixing this problem?

What printer are you using? Im planning on buying one soon but I just can't decide!

If you are mechanical minded and have a tight budget, go with the prusa i3 of Replico. Not mechanichly minded, but still on a budget, printerbot simple metal plus. No budget? Ultimaker 2

What happened to the full size one in the digital store?

Had to print large parts at center of heated bed for best results. Printing the entire job to the edges of the heated print bed caused cooling and warping. Mine was with support material and it cleaned up very well. Rod fits tight, but fits. Good print, my kids are amazed!

takes a long time to print this

This is very cool printing right now on replicator mini love it

Very nice. Not sure why, but there is no zip file generated so you have to download each individual part.

I was wondering about this too. Why is there no zip? I've never seen that before.

I made this with the Ultimaker 2
I printed at high resolution slow speed and I am super impressed at the quality of this printer and the quality of this print

Printing at 200% scale right now. The bottom jaw is turning out FANTASTIC.

Anybody else noticed the rod is way too small to fit snugly into the base and model? I will figure out the right scaling factor to use but I was surprised nobody said anything about the rod being too small yet.

About to print that part, what did you end up doing?

I think I measured the hole in the base and then upped the scale of the part in MakerWare until the X size was correct. Just make sure you are taking the dimension that doesn't have the Key portion of the rod sticking out when you look at the size. One dimension will be larger than the other by 2-3mm. Look at the smaller dimension.

Oh yeah, stand the rod up straight for sure, don't print laying down.

I printed the rod as is lying down and had no problems with the printing or the fit....FYI.

I guess the deformity that is created by printing it on its side is enough to make up the difference in tightness. When printed up and down (and no deformities are created to the round surface) the rod is much smaller than it should be.

Hello, this file is not available anymore now. I would still like to have it backed up because I want to make something cool for my son with it. Could someone that has it backed up please send me this file? It would be most appreciated. Thank you :) (lestuder@gmail.com)

When will the results for the contest be announced?

For a 'flash challenge' the model is rather large. It took me all week to just to print my entry. I'll bet it is taking them a long time to verify all the contenders. Hopefully we'll hear something by Memorial Day weekend.

Wondering that too......tomorrow is 10 days already.

Finally finished the T-Rex Skull and platform, had to print the post as an individual item, best guess is, if you print something else on the same print bed with it, then it heats and cools to much, causing it to warp and either pull all the way or on one end or the other, not sure how to post a pic here just yet

Just finished the lower jaw, took too attempts, first attempt was with the pole and the lower jaw on the bed, the pole came off the bed then one side of the lower jaw, scrapped the project and put just the lower jaw on the bed, used aqua net super strong hold hair spray on the bed tape, jaw printed flawless at .6 scale, 200% temp, 0.2 layer height, 100% speed on all prints, had I used enough hair spray on the first attempt I believe it would have worked as well, at any rate, no raft, no support material was used during the skull or jaw print.

Printed the skull so far, no problems,3H:14Min time to print, had to scale it down .6 to fit the printrbot simple table, no raft, no support mat, default position, .2 layer hight, PLA material, 200%C temp, .14 infill, teeth and all came out perfect, starting the print of the Jaw and the rod on the same table, just rotated the rod 90% and scaled them both .6 to match the scale of the scull, will report back after they have finished.

I printed the jaw no problem, I printed the rod that holds the scull up no problem, But I can't get the stand to print keeps coming off the build plate, And I can get the skull to print, won't print as downloaded and tried to rotate it etc. no luck. what's up??? Thanks Ron

Printed this thing in PLA at .06mm layer height at 80% infill on a Rostock Max. The lower jaw took 19hrs and the top skull took over 42hrs. Bloody amazing. It doesn't look like it's 3D printed it's so damn smooth.

Holy crap you must run your machine slow. I printed out of PLA at full scale. Lower jaw 2.5 hours. Upper skull 4.5 hours. I used 30% infill.

Curious why so much infill?

I just wanted something really solid. I know it was WAY overboard, but it ended up super cool. I love how heavy it feels.
Doing another smaller one right now with 20% infill. I see someone else on here did it with just perimeters and it turned out ok.

How much material did you use at that level?

What's the color of the filament used in the examples?

I scaled to 150% with ABS. No rafts and no support with a .28 layer height. It came out great except for the teeth on the lower jaw were a bit ragged. A .20 layer height would have solved the problem but then it would take hours and hours to print. Thank you Makerbot for sharing this fantastic model. I'd gladly pay $14.99 for an STL file of the whole skeleton, but alas it's only available in a proprietary Makerbot file format.

Hey MarkBenson, you could send me that file. I can convert it to stl for you.
Kind regards,
Karl

I would like to enter this contest, however the skull file will not load into OpenSCAD due to inaccuracies in the mesh. This is true for most models, including the ones from MakerBot themselves. Why are the models in such a state of disrepair?

im having the same issues

Printed the skull yesterday - this thing is awesome! Just found the full skeleton! Gutted that it isn't available as stl... would happily pay $15 for the full model if I could actually print it on my RepRap.

Almost bought the model of the whole thing... only to discover that they give you the x3g files (some sort of gcode) only... that's STUPID!! So double Mark Benson.

Hey MarkBenson, you could send me that file. I believe I can convert it to stl for you.
Kind regards,
Karl

I don't have the files. They are available to purchase from http://digitalstore.makerbot.com/http://digitalstore.makerbot.c... but they are in some sort of pre-sliced format for Makerbot printers. I guess it would be possible to recreate a mesh model from the gcode... sounds like a lot of work.

This is soo awesome! Thanks for sharing Makerbot Academy!!!

Same for me would buy from MakerBot but need STL file. Not gonna be locked into their proprietary file types to print. Y'all are missing out on a lost of cash. hmm sony memory stick, minidisc...etc Love the cool stuff just wanna be able to print on any of my 3d printers. Bet this would look awesome on our company's Objet 500 Connex.

With support, I guess?

Optimized for print without supports!

Thanks again!

How many PLA quantity does it require?

I printed these, with rafts, but no support. Settings were 10% infill, 2 shells, .20mm layer height (on a Relicator 2).
Weights:
Jaw: 36.74g w/ raft - 34.33 w/o raft
Rod: 5.12g w/ raft - 3.67 w/o raft
Base: 70.46g w/raft - 54.11 w/o raft
Skull: 75.61g w/raft - 73.87 w/o raft
These were all printed in the "default" orientations that the files came in. The weights are all pretty close to the predicted weights from the Makerware Desktop software.

I would like to see final model weight in tandem with printer settings on models also. ...Gives a good idea on your spool use, and the potential scaling opportunities.

depends on your settings like infill,resolution, wall thickness,nozzle size and thousands more.

Haven't been able to print this yet, but the system you've created to attach the jaw to the skull looks to be very nice.

Bet yours is better? Hope so I am a KS supporter ;)

Hah! Thanks Flaboy! ...Our hinges are meant to allow open and closing of the jaws, but we're still building and testing. :) ...I liked the connection MakerBot used on this skull because it seems to be nice and clean. Ours can get tough because of the function.

Awesome! Is the store download comprised of STL files? I couldn't find that information anywhere.

I bought the full skeleton thinking I could get .STL files. WRONG!. I asked for a refund (it was NOT clear on the website that I couldn't get STL files). Really stupid they won't make STL files available for paying customers!

Double that... I'm really annoyed...

The same here was hoping to build it bigger in something larger than a makerbot and in ABS or VeroWhite. Not everyone has a makerbot some here have BETTER machines.I will find out a way to print it Scan it and share the STL files..

While the files for the T-Rex Skeleton on Digital Store are .X3G, Thingiverse content will always be STL or OBJ.

Make the files available in STL format in the Digital Store and I'll buy it. Otherwise you've lost a sale from me.

Thanks! I don't have a makerbot, so I guess I don't get one. :(

add me to the list of people who would buy the full model if it was available in STL format. :(

But I do have to say thank you for sharing this great t-rex skull model!

Fellas, you do see the STL files on here to download, yes?

We're talking about the full skeleton; not just the skull.

Okey dokey....

Another marvelous project, thanks! Already planning to print and donate this one to my old elementary school too!
