Re: 3D Printed Parts on an FRC Robot?
FRC1675 has used 3d printed parts for 4 years now. Most of our parts have been done on a Stratasys Dimension 1200 but we have also had limited success with the the Ekocycle printers that were given out a couple of years ago.
Most of our parts are small, including spacers, sensor mounts, camera holders, etc. One innovative solution mated with a versablock to mount an encoder.
In 2014, we printed quite a few versablocks for quick prototyping. We did not use any printed versablocks on the competition robot, but I don't see any problem with it for certain applications.
We have also done a LOT of pulleys and sprockets for HTD belt and Vex EDR chain for intakes and sensors. We have used a 2-part pulley (ranging from 12 to 30 teeth) to eliminate the need for overhang printing on the flanges that fit together using steel dowel pins.
In 2013, we printed the plates for our custom drive gearboxes. They weren't very optimized, but it was our only way (at the time) to create high tolerance bearing holes. They were two stage reductions from Mini CIMs into 6" wheels with aluminum standoffs between the plates. Had zero issues with those over the course of the season.
