I'm looking forward into building a printer after your model, i just have one question: Instead of using aluminum plates, can I use plexiglass or another alternative?
thanks, hoping you can reply to my comment.

First of all I love the thrust washer idea, it is absolutely brilliant. Second, why go with the flex style shaft coupler? Wouldn't a rigid coupler be more ideal? I'm just curious. This is definitely going on my "To make" list. Cheers!

How much is it? for buil one like this

this will totally be my next build!! already ordered the aluminum thanks for the sweet design

May I ask what is the bed size on this build? Beautiful work!

Very nice build! Can someone please try to explain to me exactly where the thrust bearing is placed and in what way it helps?

thrust bearings are place at the Z axis motors to support the weight of the whole y axis components. It helps with better print.

This looks great! I am considering building a similar printer. How stiff is the printer? How good is your print quality?

the printer is very stiff and sturdy for what it's designed for. Print quality also depends on extruder and other tuning parameters not just how stiff the printer is.

Cool design! Does it include auto-leveling?

really solid design!

i've been modding my aluminum (20x20 based) max micron printer - and i'd like to add thrust bearings with a flex coupler for the z axis (it currently uses a stiff coupler with an open end on top).
assuming i can modify your model, would you recommend using these type of thrust bearings - http://www.aliexpress.com/item/10pcs-Axial-Ball-Thrust-Bearing-F8-16M-Bearing-8-16-5mm/32482150111.html for an 8mm acme / lead screw?

also - should another thrust bearing be added on top? or should the top stay open ended?

those are what i use. The problem for you now is how to figure out putting it together with your system. Cheers...

Which extruder are you using and how are you mounting it to your rails?

Awesome design but....
I don't have Solidworks, could you load the files as STL please?

I just found out that its extremely hard to find parts to buy because of missing proper description and instruction Some of these parts are very low quality and shipping costs are very high some of these parts i Wasn't able to find at all. I dont want to try out luck buying parts that im not sure about I think that it would be more easy to buy already made metal frame and it would be a lot cheaper about 200$ on ebay.

Hello.Well done on your design.It looks really amazing.
Is every file you used to create this provided in the downloads so that i may use it to replicate and create one for myself.

Thank you for your kind words. Other have used my design and successfully made one similar. So it should be good. Any questions, please ask...

Hello lavith! Very nice job!! I already open the solidworks files and I have one question. Where did you manufacturer the specific aluminum parts?

Thanks in advance!

If you have access to CNC machine and aluminum stock plate it should be easy to produce according to the design. Otherwise you can source out some company to make you parts but it's not gonna be cheap.

How much does it cost you?

i didn't keep track how much i spent but a lot of custom work, design and time i put into it.

What a beautiful smart design. im just ending the buildf of a finleline automation cnc machine...its will be fun to mill the parts needed for this.
also now i can use all the incorrect 8020 series 10 bits and pieces i ordered for my cnc :P

if you can build finleline automation cnc machine, this one will be piece of cake for you. Most parts you see here are milled from solid aluminum stock plate. In this design, I am most happy with the thrust bearing setup which helps to support the weight of X-axis. Without this thrust bearing setup, don't even think of building this design since it's pretty heavy with all the solid aluminum parts. AT the time I release my design on thingiverse, no other 3d printers commercially available does incorporate thrust bearing in their designs.

hi...... i want to make a 3DPrinter and i have search in internet for one that it seems to me most practical and stable ...... so i have find it your design the most interesting ....... And now i want to build it ...... the thing its that i do not know nothing about the 3DPrinters and i.m trying to see from where can i buy the components..... so i have tri.it to search some components but i cannot find them on internet .....if you can help me with this i will be very greatful

Thanks for the great download of all the 80/20 stuff. You saved me so much time. I will be sure to share once my own design is finished (and nothing catches fire).

No problem... the 80/20 is easy to model anyway. Besides I am sure that you can find the 3D model of that stuff on GrabCAD. Also, let us see your design. :-)

Hi Lavith,

beautiful machine. I thinking of building one myself.
Can you post de complete machine as a .STL file?

thanks in advance,


I have learned to hate my I3 Rework due to its inherent flaws (the nastiest one is the heated bed that refuses to stay level). Flat it stays but not level so I went to ABL but I think if a printer was designed right ABL would not be needed.

So, I too am thinking about doing what you did but I want a CNC router first and any left overs I have will go to build a proper 3d printer that is a NON Prusa.
