Man Makes Silencer with 3D Printer

Just how strong is SLA resin for printing? Robert Silvers, formerly of AAC and Remington, sought to find out exactly that. After performing some experiments Silvers determined that Siraya Blu was the strongest. And he further tested it by designing a .22LR silencer out of it.

Here is the description from his YouTube video:

I have seen people say that FDM (filament) printers make strong parts, but SLA resin printers do not. That is only true if you use typical resins. After much testing, I have discovered which resin is the strongest and it is Siraya Blu. This video is a case study in using this resin to prototype tough functional parts, such as a gun / firearms silencer / suppressor, for experimental and research purposes. I have also used this resin on an Anycubic Photon, a Zortrax Inkspire, A Peoply Moai, and an EPAX X1.

Everyone involved has a manufacturing license with the BATF.

Spoiler Alert: It worked. Well, at least for the 50 rounds used during testing.

You can watch the video below, but he warned that it is not short on technical detail. Silvers demonstrates the materials testing he did, discusses types of printers, and goes into the legality of building your own suppressor. If you just want to see the silencer, skip ahead to around the six minute mark.
