Has anyone who might have a 3D printer attempted to make some dummy rounds? I?m curious how they hold up

With my cheap PLA printer, I'd be worried about ripping the rim off.Quote:

Have not tried. PLA might break. But hey a single print will probably cost you 5c.
I'll try printing a 45acp round tomorrow if I can find a file. Should be easy enough to get back out of the glock
This is an application for 3d printing that I would be interested in.
It won?t be perfectly round because of how Printing on the x and y works together so undersize a bit.
Also the rim will be in the first 4-5 layers and should be pretty strong i have printed c clamps and things and rarely get layer separation until extreme abuse if anything do a higher infill % than normal and do a hexagon infill pattern instead of square
Or just 100% infilled and be done. [emoji846]

What about printing the bullet portion and using spent brass? I have some that are plastic bullets in brass with a plastic "primer"
I thought that well. Would probly last longerQuote:

Or print bullets to fire in your basement "gallery" using only a primer.

A high density fill on a filament printer would take forever to print and I'd still question the duarbility. I reload so I can just put inert rounds together, if it wasn't for that I'd likely be cutting them out of delrin on my mini lathe. Pretty sure they'd last quite a while.
Just pulled a dummy round up in the slicer.
.1mm layers
5% infill- 39 minutes
50% infill- 59 minutes
100% infill -1hr 9 minutes
Estimates of course.
Could also try 5 layers or more on the bottom so the bottom is solid and the rest just has 2 or 3 walls with minimal infil

I don?t anything about 3d printing but this guy seemed to have got it to work on a garandQuote:

Easy enough. Would just add a few minutes to the print.Quote:

Printed a 45acp round. Was a tight fit at first, probably due to the layer start points (little extra at each start). Once I chambered it once, it was fine. Didnt undersize at all. Did 5mm of solid base, then 25% infill. It is within .003" of perfect round.

Ejected fine. Kinda surprised. I'm just using cheap Microcenter PLA. Ran it through the glock a few times, not even marking bad.
