Re: Practical 3D printed parts
We like to use 3d printing for prototyping and replacing/modifying COTS plastic parts. We are currently using 3d printed parts to interface with colson wheels, as thicker versa hubs, spacers, and as a replacement for the battery mounting bracket. In the past we have printed pulleys, wheel inserts, and even 80-20 end caps.

Re: Practical 3D printed parts
So far, about half of our practice bot is made of printed parts, mostly because we needed more stuff from vex pro than we could reasonably get in time. Nearly all our gussets, some of our HTD pulleys, and our battery box. Of course, the competition bot won't have all this stuff (though the box will probably stay), but it made our build much quicker and more economical.

Re: Practical 3D printed parts
We print out battery holders. They have our logos on them and they have strain reliefs for the wires. Plus, it makes them way easier to hold and are plenty strong.

Re: Practical 3D printed parts
Could you upload an example image of the CAD or of a real life example? That sounds like an interesting use of a printer.

Re: Practical 3D printed parts
I tried looking for a picture, but I couldn't find one. I'll post a picture of one tonight or tomorrow, as well as maybe the STL file

Re: Practical 3D printed parts
We've printed a few things that have come in handy.
First, we printed some brackets designed to hold 4 pneumatic storage tanks on the robot. It was a pretty nice solution overall, and allowed us to stack them much easier than we otherwise would have been able to (half hour to design, then a day worth of printing instead of several hours of manual work to make something similar by hand). Then one of our students came up with a design for a winch that really looks awesome. We used a winch last year as well, but that was all hand made and had issues occasionally where the strap would jump off and get tangled. I plan to get some pictures of that setup and the new setup for this year to show a comparison - your mind might be blown at how big a difference it is, and again it saves work hours on the robot! The winch last year, for all its simplicity, took a long time to actually get together. This year, all the complexity is designed in half an hour and printed! |

Re: Practical 3D printed parts
We used ours to print shaft collars... lots and lots of shaft collars...

Re: Practical 3D printed parts
Us, too. Delicious, lightweight, very very purple hex shaft collars!

Re: Practical 3D printed parts
We're printing a radio / camera / sensor tower that mounts onto the corner of our drive frame. We will still probably protect this with an overall polycarbonate shroud once everything is on the robot.

Re: Practical 3D printed parts
11's kids printed off what they're calling "Talon Towers," just a simple way to stack Talons for some space savings.

Re: Practical 3D printed parts
How durable are 3D printed parts? Our team doesn't use them.
