3D Print Project

This has nothing to do with airplanes. Do you guys want to see the build... or not interested 'cause it doesn't fly? It doesn't drive either. I should add that it's almost completely useless, but it's kinda cool.

I'm curious. Keep going!!

Some of the planes we build don't fly either and we post about them.

Gears and pins... mostly red. Leavers, switches, arms mostly green.

This is great @davidk ! Now you can print your own servo replacement gears!

I've always been impressed that flexible chains can be printed.

Overall, this was interesting to do, but didn't work as well as I hoped. There's too much flex in the chain. I'm sure there something I could do about this, but this was just a fun, dumb project so I'm not sure it's worth any more time.
The prints for gears was excellent and the quality of the parts is beautiful.
I got to use a Tap and Die set for the first time in my life, so I can check that off the list now. The threads in the printed parts where there, but needed just a bit of tapping to clean things up.
This was engineered by a fellow named Greg Zumwalt - found him on YouTube. He builds all kinds of cool automations. When I first saw his stuff I kept thinking that there's more to this guy than just these automations he makes for his grandkids. Then he posted a video that his wife found of a much younger Greg. He was involved in the process of motion capturing Michael Jordan, and then programmed the Electronics Arts game "Michael Jordan In Flight"... a first... around 1993. When I found this out it all made sense.
Anyway, here's the end result of this little project. https://youtu.be/4u1t7rypTNA

Pre-historic retracts.

Neat project...... and well worth posting.

Love it!

That is so cool. Just amazing.

tuck · April 15, 2021, 07:15:48 AM

I am interested. I would like to see more of the printer.
1. What brand is it?
2. URL from where you got it?
3. Is there a brand?

It does not fly. But it will help build parts that will help in flying.

Thank you
Tuck

Hi @tuck ,

The first photo in @davidk 's thread shows the printer and name.

It is a Prusa printer, MK3S+. They also make a Prusa Mini+. You can get both printers built or in kit form. I got the MK3S+ built and the Mini+ in kit form. I've never experienced such perfect instructions as I have with this build. Colour coded instructions and multiple images per step along with user notes per step as to what they found or did. Many of the parts are themselves printed by Prusa. Highly recommended.

Thank you Andy. How can I missed that?

Very cool!!

But 3D printers CAN make stuff that flies - apparently! I have found two companies that design 3D-printable planes: Eclipson Airplanes (https://www.eclipson-airplanes.com/) and Plane Print (https://www.planeprint.com/)

I am currently working on the Eclipson EBW-160 flying wing. It has a 1.6m span, and the airframe without electronics is supposed to end up around 450 grams. All up weight is supposed to be 1.1 kg or so. It has to be printed in sections (cause the printer can only handle 220 mm x 220 mm x 250 mm), and then these sections get joined by CA.

I just finished the majority of the airframe, and what I have so far is 410 grams. I still have to print the ailerons, motor mount, and the hatches and smaller bits.

For reference, my printer is a Creality Ender 3 Pro. I printed this with PLA, although there is a new material out there called lightweight PLA (LW-PLA) that is apparently infused with some foaming agent that can reduce the weight by 50%

It is tougher to print with though, so I'm taking the easy road for now

There is an assortment of over 100 models available online from various individuals and companies, a mix of paid and free, listed here:

The list is being updated and modified very often.
