In this thread is a discussion https://vexforum.com/t/3d-printing-a-possibility-for-future-games/32259/1 about using 3D printed parts.
I’ve had experience with the cheap 3D printers. You might get something small that works, but nothing that would be strong enough (like gears).
But the VEXU teams are in year three of being able to do 3D parts. So I’m asking that they show us the parts they made.
I can’t find it now, but there was a VEXU team that posted pictures early in the season build that was awesome. It has 3d printed parts on the chassis, shooter, and I believe the intake.
That would have been VCAT. Their reveal vid is here: https://www.youtube.com/watch?v=lsIQkfGYyrA&feature=youtu.be
I remember 2 years ago, after toss up, @Cody revealed a pretty cool robot that he intended to 3D print parts for: http://polynomic3d.com/user/smith/H5/
