Thank you for a great model.
I have succesfull printed all the parts on my FDM machine Ender 3, except the electric board I am facing issue with supports which formed are very hard to remove. any suggestions to print it properly?
Thank you

Thanks for your feedback. At this time since it was printed on an sls printer I am unable to provide results from FDM style printing. Sorry about that. Let me know if you do find a suitable layout to help with supports though Rudra3d

thanks for clarifying the soution i used for that problem is that i used manual support function in simplified 3d and put support blocks in extreme position which did the trick i dont call it a perfext print but its quite satisfactory print will upload the make soon thanks agin for the wonderful model.

Ahh good to hear you were able to find a solution. Looking forward to seeing your completed print.

I'm not sure why I never thought of doing this - best idea since sliced bread.
I mean even if it's not the most durable thing, it would have to be damn handy as an emergency spare.

Something I could really use on those long trips into remote areas.

Not sure it would hold up in a practical use situation but wouldn't it be amazing if it could!

what is the best 3d printer for print like this ???

I notice some of your parts in the video are multi-color pieces. Did you build in pauses in the print to change filament or did you paint the pieces after completion? #3dprintnoob

I should actually mention nhkierst. I died all components of the Alternator except the white pieces. Then I painted parts of some of the components :)

Hi. I've juste found your project and god damn it's a really good idea !

I'm from france so sorry if my english isn't totally understandable.

I've still one question for you : what was your post treatment painting process ? Ty

Hi nhkierst, I actually painted the pieces :) Cheers

Very impressive, thanks for sharing. @fransfalco the tolerences are .5 and .7 should work for about any well calibrated FDM printer.

Just reading through the amount of content, information and instructions you have including - outstanding project!
Interested if you have printed a version using FDM printing - looks challenging?

Hi francfalco, thank you. FDM print will be coming :) There will be a good amount of supports needed etc. The current design is built with .5-.7mm tolerance and so it should print with fdm.

Very cool. But now of course I'm wondering if it could be modified to generate electricity lol

It would be cool to see using, but I think with the time involved, a real one would be best :)

Thanks Singerich & flyingmnokey35

This is exactly the kind of learning tool which I wish we would use in my physics class when talking about electricity and magnetism. Much better than powerpoints and laser pointers, in my opinion. Cool design!

I wish I had something along these lines in school as well PurplePepperEater. Cheers

Wow! This is a beautiful design and the print quality is outstanding! Good job!

Thanks for the kind works OG-Spark and everyone else :)

Im not a teacher but I am a dad and this is awesome to teach my kids with! Thank you

Your welcome NEONX18. Thanks

Thanks BreaknMake!

You are welcome! I love to see people who do stuff for education. (=

What year Chevy is this off of, and how long you think I can make it last if I put real parts inside?

Hi Jay, It wasn't designed for end use and so I cannot comment on longevity if real parts were introduced to the 3d printed case. This alternator came from a 90's era Chevy Pickup truck. Cheers

Love this, very cool. How many amps will it make? <<just kidding. This thing is great.

Be something else if it worked eh Jerry. Thanks as well :)

Mate, I run an automotive repair shop in Australia. I have had your caliper on my parts bench for a few months now and I look forward to having this on there as well. It's been great for showing customers whats wrong with their vehicles and whats needed to fix it. I'll be keeping an eye out for future models. Tip is on it's way.

Edit: Am I doing something wrong? The parts are showing up in Cura as being just a few millimeters in size.

Hi CustomsUnlimited. That's a really interesting way to use the Brake Caliper and the Alternator in the future. I would have never thought of that. As for the design, it was originally done in Inches. I received another concern about the files importing small and so I have put up new STL files done in MM. I tested each piece in Cura and they all import perfectly. Sorry for the mix-up CustomsUnlimited. I hope you like the new Alternator model. Cheers

Chris , First thanks for uploading it over here, Second What Scale did you use to print. currently the Housing back is showing 2.61 x 5.43 x 5.20 thanks

I have updated the model into millimeters which should solve the import issues. Cheers

This is an amazing piece of learning, 3d printing, and design. Well done sir!

Thanks a lot aaskedall. Exactly what I was going for and I hope it helps out a lot of folks.

Absolutely AWESOME!

Thanks SkyRider!

Very cool idea for the visual learner!

Thanks so much bsolo09. I strive for this with each of my models.
