3D printing fun!

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Today since the weather is so crappy I have this fantastic idea. Lets 3D print a hole bunch of things for my new gun. I designed a silencer and printed it out. Plus i 3D scanned a pellet and printed out 20 of these in my high detailed resin printer.. I put the pellets on my small scales and each of them come in at 1 grain each...well 0.985 grains to be exact.

The next thing to do was to see if these even held up under high pressure and would they seal in the chamber.

Well it turns out yes to both. How fast are they? 1300fps at full power (10 pumps) lol they can put a hole in a can and its a bit of fun. i would say accurate out to 15 feet. 

Now to the silencer. holy crap. it worked really well. didnt expect it to do much but it made a huge difference.

I will be doing more tests tomorrow and probably put up a youtube vid on it for a bit of fun,

	I'll be keen to see the silncer. Have heard they work well printed. Maybe you could print a good baffle system to go into carbon fibre tube if you think itll be strong enough to withstand the air shock without being attached to the outer shell.

	I printed it in two halfs and it is stuck together with duct tape. I did it like that so i can easily pull it apart after a few rounds to see how the internals are holding up.

	Oh sweet! So if I have you length and diameter, you could make one to size?

	Interesting. 3D printers are amazing and it’s only your imagination that’s the limit to what u can make. I was thinking the other day, a good project would be a tray to hold pellets in, head first, down a suitable depth and carefully sized hole. The purpose of which is to quickly and easily drop 100 pellets onto the tray, jiggle it around and let the pellets drop into the holes, head first. Once they are in the holes you can inspect 100 skirts very easily, and reform any damaged ones with the end of a ball point pen if needed. If you have ever reloaded for powder burners and used a “self righting” tray to get your primers all facing up the right way you’ll know what I’m talking about 😉
	Walk quietly, but carry a big stick.

	I just put those 3d printed pellets through the misses crosman fury NP it spat them out at just over 1800fps lol...sounded like a rimfire going off. super loud.

	Well after more testing with my 3d printed silencer i can say that it is not good. the thing is hitting all over the place. so i shall have a rethink and see if i can come up with a better design. Might try printing it hole instead of in two halves and see if that improves anything.

	So i shortened the silencer by 20mm to 160. made the internal hole bigger and left the baffles the same. Printed it in one piece this time. Ive put 10 shots through it and it is bang on target now and reduces the sound down just as good. Just have to work on the wall thickness now as it is a bit thin.

	Are the tolerances from the printer good? For example if you printed the exit hole 5.5 mm for a .177 or a 6.5 mm for a .22, would it be good enough to stop clipping? Does the print include the female thread and all, so you print, then just thread it on? Sorry for noob questions, I have never printed stuff before.
