Best filament for pews

What do you guys recommend is the best filament for pew making. Out of pa6cf20 or I believe it's pa20cf?

Looking for something with little more strength than pla when it comes to abuse.

Cherry popper print orientation

Does anyone know or have pictures for the print orientation for the cherry popper and where to put support blockers? It is not in the version of the PDF in the files that I downloaded. Or in any that I can find. Thanks.

Please help with printing issue.

I think I'll wait forever in the printer guys sub, due to specific print :)

Trying to fit test print the Fatty slide. One corner rips from support and warps every some layers. The part printing over it, but next corner warps, and so on over the whole lenght. Printing at 15degree angle, ESUN PLA+HS, nozzle 215deg, 100% cooling fan speed, 80% side fan speed, Creality K1max, top cover removed.

Laugo alien update + questions

Hey y’all, I’m the guy who is designing the 22 LR Laugo alien. I believe the base design is finished and I am printing the lower right now for testing. There are some changes that I want to make before I release it to the public and that mainly is I want the hammer and fire control group to be made of metal, since it is hard to get such small pieces to function perfectly without screw ups later down the line. The design could be fully printed however I feel like metal parts on this gun would create a smoother feel and safer handling. that being said, I am thinking to release it first as a paid closed beta as I also am a broke college student who cannot afford to put thousands rounds through the gun to test it, and can’t afford to get several versions of the fgc machined out just for testing. I am also also thinking of selling parts kits with the CNC machined metal pieces for the fire control group of the gun. please let me know y’all‘s thoughts on this. I don’t feel safe without having a lot of testing done on the gun to release it to the public. Let me know what I should do. I do fully plan on making the gun free for public use whenever it’s fully done it’s fully done. I have also never done an actual release of a gun before. Nothing I have said in here is set in stone yet, so don’t get mad at the paid closed beta idea (it’ll be free when i get enough testing on the design) Any advice is appreciated, not really sure on how to release this design with the proper testing. Thanks!

Has anyone tried printing and using metal Filament?

Im looking to make more reliable possible usable prints and was wondering if anyone has given these a try? Looking to use them in my suppressor builds as baffles.

Curious to see if anyone has had a chance to use them for this application or another and has any advice or opinions on the matter?

Filaments for P1S?

I am going to print a 22 on my P1S, and it is relatively easy to print advanced filaments with it. I wonder if there is any guide which ranks filaments from best to worst regarding 2a applications? Seems like a lot of people are printing PA6 GF/CF but that requires a hardened 0.6mm nozzle which I don't have. The whole "absorb moisture after printing thing" is also confusing me. What about ASA? Is that still better than PLA+ or should I just go with PLA+?

When would helping someone else print a gun cross into "manufacturing?"

I'm aware that I can print off guns and parts for myself and it's legal but I can't legally print off guns if I intend to sell or give them away. My question is when does me helping someone else become manufacturing? i.e. let's say I have a 3d printer, my friend comes over and files are prepared but he hits the start button. Is this manufacturing? Alternatively on the other end if I have a printer, it is set up and calibrated but not specifically for his project, but he brings his own files, his own filament etc is that still manufacturing? Thanks.

Print help

Is there any settings in my slicer i can change to help clean up overhangs? I just finished my 2nd dd19x frame and everything came out very well functionality wise but the underside of the pic rails, trigger guard etc. is kind of ugly and rough so if anyone has tips to help with that i would be very open to advice
