bunkerguy 0 Posted February 24, 2014 Report Share Posted February 24, 2014 Would you buy a printed 3D Drum Magazines? Would you spend $120 on a 30 round drum that was 3D printed instead of the $320 drum from Alliance Armament? Quote Link to post Share on other sites
SGL 530 Posted February 24, 2014 Report Share Posted February 24, 2014 I would rather have the proven MD20 or or two CSSpecs steel magazines than another "also ran" drum. 2 Quote Link to post Share on other sites
NM0 586 Posted February 24, 2014 Report Share Posted February 24, 2014 3D printing is coming along quicker than many realize. Some metals and carbon fiber. Were at the dawn of a new era in manufacturing (especially do it yourselfers). 1 Quote Link to post Share on other sites
Big John! 2,062 Posted February 24, 2014 Report Share Posted February 24, 2014 I had to vote no at this time. When I see things being proven worthy, I'll probably be begging for them. Quote Link to post Share on other sites
pedal2alloy 206 Posted February 24, 2014 Report Share Posted February 24, 2014 Eventually the materials will be stronger, but right now it wouldn't tolerate even 1 round being fired Quote Link to post Share on other sites
Bvamp 604 Posted February 24, 2014 Report Share Posted February 24, 2014 unless its a gun from an old lady at a yared sale, im not buying anything gun these days...not even ammo. anything made well is saleable though Quote Link to post Share on other sites

Would you spend $120 on a 30 round drum that was 3D printed instead of the $320 drum from Alliance Armament? I had to check the thread date to make sure this wasn't a necropost... NO ONE has bought an AA drum in years around here. I would rather have the proven MD20 or or two CSSpecs steel magazines than another "also ran" drum. What SGL is talking about can be purchased here. On sale right now for $95. http://www.mdarms.com/index.php?main_page=index&cPath=13_1&zenid=2rqf8mt7r4jpislporr2r9beg3 Here's an old forum friend running the snot out of gang of MD-20s. 2 Quote Link to post Share on other sites
csspecs 1,987 Posted February 24, 2014 Report Share Posted February 24, 2014 3D printing is interesting.. But I don't see it having an edge over conventionally made items for some time. I'd suspect that the 3D plastics would not stand up to the abuse. 4 Quote Link to post Share on other sites
toothandnail 275 Posted February 24, 2014 Report Share Posted February 24, 2014 We have and use a 3d printer for some stuff, the available materials for the small business/DYI guy will not hold up to the stress of a drum and recoil. Quote Link to post Share on other sites

pedal2alloy 206 Posted February 28, 2014 Report Share Posted February 28, 2014 The current 3D printed plastic has less than 1/3 the tensile strength and 1/7 the impact strength. If you look at fiber reinforced polymer which is used to make magazines and lots of other things like tools etc, it has embedded fibers throughout, but the 3D printer builds up the material in thin layers so it doesn't allow for fibers to span across the layers or intertwine thru the material. Of course eventually these issues will be worked out and we will all be printing out M16 and HK91 lower receivers. Quote Link to post Share on other sites

That offer open to the rest of us? I have some very hard to find exterior automotive emblems that I've thought have having printed. Do you have a material that you believe will handle the test of time in an automotive environment and accept paint? For that matter, will any of those materials accept chrome? I have some experience with rapid prototyping (printed or otherwise) and I haven't found exactly what I'm after yet. Edited March 6, 2014 by Maxwelhse Quote Link to post Share on other sites

I have some experience with rapid prototyping (printed or otherwise) and I haven't found exactly what I'm after yet. We use primarily PLA, it starts deforming/melting about 200*, it would take some filler primer & sanding to get a slick finish that looks good painted. ABS is another material, we haven't printed much with it. I'd be willing to try a file if you got one , how big is the part? Quote Link to post Share on other sites
Maxwelhse 1,285 Posted March 15, 2014 Report Share Posted March 15, 2014 The part is small, maybe 2"x6"? That's the problem I've got. These are fairly intricate fender emblems and I'm afraid I'd never get it filled and sanded right. They have very light background textures that I think are fairly impossible to prototype accurate with the current technology that I've seen (maybe ABS would perform better?). Most everything I've experienced that is prototyped feels very porous and somewhat sandy. That said, I have seen a several different functioning coil springs at specifically engineered rates. It really is amazing how the technology progressing. Quote Link to post Share on other sites
MR_22 35 Posted March 15, 2014 Report Share Posted March 15, 2014 I'm a new member to the forum today. A couple of months ago, I purchased a new dual-color 3D printer from MakerBot, with the idea of printing gun accessory parts. I don't mean parts to MAKE a gun, but to put ON a gun, like magazine finger rests, magazine spacers, and maybe even magazine round extenders, grips, and whatever else. I look forward to exploring what I can make for my new Saiga-12. Here's a thread I posted to the Beretta forum about making a magazine spacer for my Beretta 102 .22LR pistol, which is no longer available, so you can't get parts: http://berettaforum.net/vb/showthread.php?t=105322 Quote Link to post Share on other sites
G O B 3,516 Posted May 13, 2014 Report Share Posted May 13, 2014 The high quantity 3D printers and premium materials, including metal are still to $$$ for most parts. The quality/price point is getting closer, but is NOT here yet. Quote Link to post Share on other sites
