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.

See that?s my worry is they just won?t hold up. I really have no experience with 3D printing

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"

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

I mean you would get lots of IAD training in

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 garand

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

Hot glue sticks work reasonably well, either cut or injected in bullet molds. LEGO heads work in 40SW.

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.

Didn?t mess up the rim or anything ejected just fine?

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