3D Printing Parts

Very true, it will be a bit of a challenge indeed and I just hope it works out in the end, everything looks like it will but I am at the near tipping point for PETG’s tolerance so I think only time will tell at this point.
I figured ships eventually would just considering how useful it can be and the need to be versatile in fixing problems.

While on the topic of 3D printed parts, has anyone here ever used a laser cutter to produce small parts? Of course, not one of those million dollar Trumpf machines, but the new generation of $400 cheap Chinese tube laser machines. They’ll easily work with many plastics, but to cut metal you’d need something much, much beefier.
I have a small home laser, and it is remarkably reliable for small plastic parts that can be cut from sheets of plastic. Very fast, and it just looks plain cool to see the laser at work.

I’ve never used one but one of my co-workers has a CNC machine to cut circuit boards.

Never worked with a laser system, but several water jet machines and a couple of plasma cutters.
-
Waterjet systems always fascinate me – it is incredible to watch water (and a little bit of grit) slice through metal like a slice of bread.

Okay, for some feedback.
We got the PETG in and printed a Peg, it help up to the temperature just fine so far, only ran it through a couple of times but it looks no worse for wear.
Only problem is figuring out how to make it snap on the belt without breaking the part that holds it in place on the rail.

Do you have a way of measuring the Durometor rating of the original and yours?
-
No, unfortunately not.
-
Any local engineering colleges or plastic manufacturers? They’ll have one.

It’s part of the elasticity to be able to snap over the bars. Opening the gap up a millimeter might make for them to fall off when hot. I’m sure that the expansion of the plastic from heat has to be a factor as well in the original design and material spec.

Yeah, you are probably right, We’ll see. Once my printer comes in on Friday I’ll be able to test a lot more, especially in how the infill pattern is done to allow more flex.
