3D printed AR-15 Fail
Not sure if this is a dupe or not, but thought you guys might like this.

3D printers are pretty cool, I have a crown in my mouth that was made on a 3D printer while I waited at the dentists office. I broke a tooth and was able to go in to the dentist and walk out the same day with a new tooth!
Now as for 3D printers used to make receivers I don't think there's strong enough material yet, but some day in the not too distant future it will create a fascinating 80% build landscape. |

I see it as more of a success than a failure.

maybe they need to make a design that uses simple things as reenforcements like nails
i wonder how it would have done with a 22lr conversion |

too bad this one failed....soon enough this method may be a viable process to make a lower. |

Like I said before 3d printers have the potential to make the 80% scene VERY interesting. Just imagine building your own Glock for starters and with RRA introducing their polymer 1911 it shows you can indeed make guns traditionally made out of steel frames from polymer frames as well.

He used a very CHEAP 3D printer and a cheap material to make that receiver. The cheap 3D printers use ABS plastic, not unlike lawn sprinkler fittings. An expensive 3D printer has the ability to use higher quality materials, and a receiver would NOT fail.

Just because a printer uses ABS does not mean that it's cheap - the Fortus line of machines (which is what Detroit Gun Works uses) begin at $45000 and run ABS. |

Thread title fail. The prototype firearm functioned for a while unlike this thread.

you crazy all the recoil force is placed on that since that is where the stock mounts

3D printing is amazing, but if people start "printing" guns, the BATFE could simply redefine what the restricted component is.
In Germany the controlled component of a firearm is the barrel. They are serialized to the gun. If you want to buy a conversion kit, it requires the same permit as another gun. Frankly, this makes sense since the barrel presumably is to hardest component to make. Try 3D printing a barrel....

The forces from recoil are just compression and, that is limited since the upper receiver is right there. With a semi auto build, the forces from recoil and the forces from the buffer cycling beat the buffer tower in both directions. Even a .22lr upper is harder on a lower than a bolt action 50BMG is.

Did you ever apply the carbon fiber fix to your buffer tower? |
