Building a working AT-AT big enough to ride on

If James ever stops building these huge machines, filament prices will plummet. I would be really interested to see how many kilos he puts through the printer every month. 😂

[@koleoidea]

Yeah i would love to see a count in the video of how much filament he used in each video like a score.

The factory is next door. The filament comes straight out of their extruder, through a hole in the wall, and into his printer. Nice.

[@RyanCrossOfficial]

[@sortaspicey9278]

I genuinely feel that you are single-handedly proving just how good 3D printing can get. I still see a lot of people. Dismiss 3D printing is some crappy week frail process that produces fragile parts that want to disintegrate at the slightest touch, but you have proven quite the opposite honestly

[@MrRevenant333]

Good is debatable. The quality of his prints mostly isn’t that good because he needs functional parts quick. That’s absolutely fine. But is that a measurement for “good printing”?

[@Memphisko]

@@MrRevenant333 i think it means 3D printing has valid use cases outside of gimmicky multicolored toys. it's not about fine detail or quality and surface finish. it can quickly chug out huge strong parts for massive robot prototyping :D

[@dieterjosef]

Yes and no. It's great what James is building but 3d printing has proved that already by being used in the airline industry and elsewhere. Of course with much higher costs but without having to produce large numbers of pieces.

[@Eric-vq9nq]

His projects are awesome, but 3D printing is a terrible choice for fabricating something like this unless you are sponsored by 3D printing companies. Just these legs would be thousands of dollars in print filament and an insane amount of print hours even with the large nozzles. You could use more aluminum extrusion and make the other parts from glued up layers of MDF or plywood for a small fraction of the price and time. It would likely even be cheaper to have a lot of the 3D printed pieces laser cut and formed by one of the many companies that offer those services. It would also end up lighter and stronger that way.

[@starlordpro2077]

if this project was real sized then plastic wouldn't be enough to hold the weight due to the length of each part.. not to mention he wouldn't be able to print the parts due to their size either...

[@BH-rx3ue]

Cant wait to see the 1:1 scale replica! thats the natural progression

I wonder if material science would need to be involved at that point or of it's just a simple job.

[@dylanstonemusic1614]

1:1 scale is 22m tall, that's a bit much for one person to build. He'd need something a little more than just extrusions and 3d printer filament to build it

I know James is unique and special but it’s still wild to me that a “regular” person can do this kind of stuff at home now. Small scale prototyping, manufacturing and CNC has allowed hobbyists to build some seriously crazy stuff! I love it. I also love seeing comments about young people being inspired to learn engineering. Just amazing all around! You should be proud, James!

Wow. A part 2. You know it’s a huge build if James breaks it into multiple videos.

[@JulienVanier]

You're my favorite robotics builder on KZbin. You're such an inspiration! I just finished converting my kid's old Power Wheel to remote control with a 3D printed sprocket on the steering column to turn using a motor and a chain. It's super fun to see a 5' skeleton driving a little jeep 😂

[@meribor]

Classic KZbinr Bait

[@xManzi]

I wanted to write something smart, but I am speechless... THIS IS SOOOO COOOOL!!!! It just shows how powerfull of a tool 3d printing really is when you design everything around it. Not some tool to imitate production of a part, but a part designed for 3d printing can as usefull as any other technology.

[@Yavorh55]

That printer is a very interesting solution to an actually common problem. Lots of people print long rectangle parts (or ones that fit in a long rectangle), but few print huge cubes - so having a printer that violates the Cubed print volume, thereby saving some space, to make one or two axises longer makes a lot of sense!

[@kwaaaa]

What's amazing is most KZbinrs are 8 months into a project "here's part 45 of my build". James is like 1 month in "here's most of an AT-AT walker". This man doesn't sleep!! 😀

Seems like you could bolt part of a brake rotor on those smaller gears and have a caliper that holds the pads under pressure with spring tension, until a solenoid is energized by the servo power, which in turn releases the brakes and allows the gear to move freely while the servo motors around. Or program some kind of delay to the motors while the solenoid engages or disengages the brake. This would act as an automatic position hold without needing to constantly input power to the motors.

We all have talents in different areas. I am so thankful for the inspiration that comes in software engineering for me. I am amazed nonetheless by the inspiration or design that comes to you in mechanical engineering. Maybe that comes a little by experience too, just doing the stuff we do until it becomes something we can create with plus the University degree. Anyways, if I get a chance it would be fun to design more in Industrial Design which I think you do some as well since it isn't just parts and unsightly prints of default mechanisms. In all, I think I'm just talking about something I heard of as design thinking.
