As of current, there is no 3D printer material with sufficient strength for this application.
PMags need their covers because the material is WEAKER than aluminum. It would be better to use a 3D printer to make the pattern to make the molds. Or to make dies for home pressing of aluminum magazines. About the only real issue is the spot welds, these could be replaced by flush rivets which could be installed with an interior bucking bar and hammer. |

The die won't be cheap, but you will have a mag stamping die. I believe the die for the Barrett 10rd mag cost $15,000. That was from when I worked there. |

Yup. 3D printers get better every year, though... Some newer ones work metals. In time, this may be possible. |

Isn't translucent plastic a bad choice for strength? I thought that's why Magpul never made them past testing? They were more brittle, and that would have been with compression molding.

Quoted:

Therefore, do not worry... you will not be under gunned when you confront the PCP-pumped felon who needs 14 shots to go down anyway with your 10 round limited firearm. Hell, why stop there? Let's make the limit 5 rounds, you shouldn't need more than that for hunting either. Nope... that criminal won't be toting a firearm with a 3D printed 15-30 round magazine he printed with instructions off the internet. 5 rounds should be fine. Actually, let's alter the deal again... let's make the limit 3... Oh, btw... laws can also be struck down by courts simply on the basis of being unenforceable... even if the subject/lawn in question is good policy, not covered constitutionally, etc. When 3D printers get out of where computers were in the '80's they will certainly push the envelope of enforceability with regard to any magazine capacity ban. I think people have it all wrong here anyway. We should promote the highest capacity magazines as possible. Quite frankly, the more rounds you add to a magazine the more difficult it is to design one that functions properly. Each round adds that much more force/resistance/weight to be overcome by an increasingly larger spring, which then creates its own problems, etc. In general, they will tend to misfeed, jam more, etc. Let the sicko's continue to think they are the best. Also probably a good reason to start with coming up with a pattern for a 15-20 round magazine for a 3D printer first.. should be quite a bit easier than a 30. |

Printers will always be slower than traditional methods. And more expensive.
A good injection molding machine would be 1/4 million. Molds about 50k. Magpul probably has the lid on the Zytel they use but nothing stops you from buying the bulk resin from DuPont. It would be far better to invest time in making the molds. If you could make the molds in castable tool steel via lost wax, using the 3D printer to make the wax patterns is a far better use for this technology. |

Hence why they are prototyping machines, not production machines. But... Imagine a draconian future where Space Nazis occupy the US and owning stuff to make mags is a crime. No one will make molds for you. Get caught with them and its evidence against you. But a 3D printer? No crime there. Files are easy to hide. Caches and buffers easy to clear... If one doesn't sit on inventory, then unless they actually catch the act of printing, no crime can be proven. |

I bet JD Weld would be *good enough* for a near-disposable magazine. Too brittle. Zytel is a Nylon with fiber reinforcement so it has exceptional material properties. JB Weld is a filled epoxy so it has decent compressive strength but horrible flexural and tensile properties. But epoxy isn't too bad for epoxy composites, using carbon fiber mat/cloth. Basically, you could make the molds using silicone rubber, then cast in halves and bond them together. Hell, you could even use an existing magazine to make the molds. Because the molds will mirror the surface finish of the existing magazine, it would be very smooth so no feeding issues. You could vary the layup schedule to enhance strength in the lips, base and mag catch. Then use glass in the rest of the areas for cheap bulk. Weight will still be less than aluminum with greater strength. I just might have to try this. |

since the 3D printing material is too weak, would it be possible to just make it a bit thinner and wrap it in carbon fiber? not sure of cost effectiveness but would that work?
