Sort of dupe.
And I still want one. If nothing more than for a paperweight. |

If you read through it.... it seems that this would definintely work with a .22lr conversion. I bet they could even use a printed upper for .22lr.

Quoted: Too bad both lowers broke. More of a problem of using lower and uppers specs that are designed around metals, which is why they are testing. With the current 3D printing tech the designs will have to evolve to take that into account. A test I did a while ago using the traditional dimensions and specs.  |

Hmm, they are going about it from the wrong perspective imho, they are working with a weaker material instead of trying to make it look like a lower thats made out of metal they need to start with the basic FCG area and add material to it for strength, make it look like a cav arms lower and I bet they would have less issues.

I kinda wish this had waited until 3d printing had become more mainstream and there was more penetration into the home. Why? Because at the moment 3d printing is in its infancy and so this printing guns thing can be handled now before it hits critical mass. Had we all 3d printers and THEN someone thought of printing gun parts it would be much harder to stop. Or at least we could crank out a bunch of parts before something was done about it. Just my 2 cents.

What is the legality of creating a functioning lower without an FFL?
Are you good to go as long as you don't make them for the purpose of selling them? |

How many rounds are they getting per lower? I hope to blow them away with a redesigned lower here in a month or so when it's done. (I have to get an LPK during this craziness

Just my 2 cents. 3d printing can be done with cardboard, the software to take a 3d model and slice it into layers of thickness determined by the material have existed for a while. Cat is out of the bag, just for a proof of concept I'm thinking of doing a lower receiver out of printer paper and an epoxy or resin infiltrate. |

At the point at which it would be economical (current panic buying price increases aside) Magpul would not be able to sell them to us anyway. Materials for 3d printing are still a bit expensive I understand, and the process takes a lot of time. Before the current mess I could go down to my local gunshop and but a Pmag for $10-12 and play with the latest toys they got shipped in. If a ban on magazines happens then all that goes away and 3d printing of Pmags becomes not just morally justifiable, but one could almost say it would be a patriotic duty. However I get what you are saying and would rather support Magpul then copy their stuff. |

Printing an AL design from polymer is hardly revolutionary or impressive. |

Printing an AL design from polymer is hardly revolutionary or impressive. Think less consumer grade AR-15 lower receiver and think more Liberator pistol. All though I would rather have something like you are describing, because I like guns, and like to shoot them a lot. |

Printing an AL design from polymer is hardly revolutionary or impressive. Think less consumer grade AR-15 lower receiver and think more Liberator pistol. Polymer can do much better, you just have to do some actual design work. Printing a lower per the AL design is like building a bridge to print but using balsa wood. However, if you design the bridge around balsa wood from the get-go you can end up with a perfectly fictional bridge. Every lower I've seen printed is snapping at a 45 degree angle just FWD of here the buffer tube attaches. It's failing from the bending moment the buffer tube is loading the lower with during recoil. This needs to be fixed with a geometry change, not a "let's try the same design with another plastic" change. |

Caboose314,

I think we all ought to ban together and print the hell out of some plastic lowers, regardless of whether they'll hold up or not. Then next time some fudd county offers a buyback program we could go bankrupt their system with our cheap printed lowers and take the money & go buy ourselves some nice rifles. Who's with me?

I have a design mostly complete, I just need to get it printed and order parts. I'm looking at early Feb as my goal for a functional lower. The holidays have slowed my project to a halt for the time being. |

Granted you can transfer them at a later date, however if you make a habit of it I imagine the ATF would feel different about the whole "personal use". |

BULLSHIT Is DEEP here.
There is rather a large difference between a 7075 Aluminum FORGING and a piece of plastic. Get back to me when someone succesfully prints up a wheel bearing, or an aircraft turbine blade. . You think someones going to PRINT up a chrome lined barrel? How about a bolt ? Just put in an "INK Cartridge " full of 158 Carpenter steel, and print up a nice tidy MPT Bolt? . Might as well have them print you up a few boxes of primed cases. Oh wait, we dont have Primer INK in stock. |

Not with the way the current machines work. The part can't move or the printer will "lose it's place". Adding material would also take up space that there currently isn't a means to account for during printing. You could however print in small chunks and assemble them with epoxy and fibers. |

So build a bracket to support the buffer and bolt it on in place if the takedown pins. Two side plates and a back plate that would be secured by the castle nut. Wouldn't be pretty but would distribute the stress.

They want to design a totally printable weapon based around the .22 lr round as sort of an untraceable liberator type weapon to totally invalidate gun laws. I doubt they can make a semi auto pistol like that, but I think the idea has possibilities. That is a couple years down the line. This is just a first step for them to try and get some publicity/funding for their kickstarter. |

I have a 4 axis CNC machine, Solidworks and I am a geek....I have been kicking around the idea of making a lower out of 7075 billet.
I can't see how 3d printing resins could hold up....right now this shit is just for prototyping. Actually I think it would be interesting as hell to do a CNC machined billet magazine.... |
