Future of 3D Printing Liberty
    #26948905 - 09/22/20 07:50 AM (3 years, 4 months ago)

With the cornovirus speeding up research, how can 3D printing & liberty be investigated for our generations future so people will have basic human rights to 3d print very special things

What's a 'very special thing'?


--------------------
Let it be seen that you are nothing. And in knowing that you are nothing... there is nothing to lose, there is nothing to gain. What can happen to you? Something can happen to the body, but it will either heal or it won't. What's the big deal? Let life knock you to bits. Let life take you apart. Let life destroy you. It will only destroy what you are not.

I guess we'd have to know what special things you're talking about, but it would be very difficult, if not impossible, to tell a 3D printer it couldn't print, for example, guns.  3D printers operate using Gcode, which is basically just a set of X,Y, and Z movements along with some other parameters (heat, extrusion rate, etc).  Even if someone stopped a printer from printing a specific gcode file, anyone could make almost insignificant alterations to it to get around the limit but not really change the final product.

I guess I'm not sure what you mean.  3D printers started as hacked together machines put together with open source hardware.  You could still put one together with a RasPi and some stepper motors pretty easily.

It's interesting that you can 3d print guns out of plastic, but wouldn't it be better to have a CNC milling machine or something and make them out of metal?

There's pros and cons to both.  A CNC'd AR lower would certainly last you longer, but I think the machine to do that will run you a few grand on the low end (I haven't looked at the Ghost Gunner in a while).  For under $250, you can get a printer and enough filament to pop out 5 lowers, and every 5 after that will only be another $20 in material.

Apparently the current model of the Ghost Gunner is $2100 plus $100 shipping. Doesn't really seem too bad considering.

Yeah, a more expensive machine, and a more skilled operator. It could probably be done with a $1200 mini-mill with a rigged up DRO and a very skilled operator who could do it by hand instead of CNC.

I will say, SWIM printed a PETG lower and has over 500rds through it without any signs of failure.  If you're looking to make a gun that will last indefinitely, you probably want it metal, but if you just need to arm your militia real quick and cheap like, that money might be better spent on printers and plastic.

And it would be a total piece of junk. Buying a cast lower and then machining it isn't hard, and I believe can even be done manually. A cheap mill to do so is probably in the $1k range. If you want to step into the CNC range, you are going to go up quickly in price. But if you aren't running parts in multiples then it's not really needed.

I think it depends what you need it for.  If your end goal is to have the nicest rifle around, you're probably going to just buy a lower somewhere.  If you just need a gun to get another gun in the case of some sort of revolution, a printed lower works just fine.

Most low end printers have some serious short comings when it comes to printing. You have to spend a fair amount on upgrades to get nice functional prints, and even then, they are still pretty iffy. They are also slow as dog shit. You could machine lowers from casting in mere minutes where as printing takes days.

I think the Ghost Gunner only completes lowers that are already 80% finished. It doesn't produce a finished lower from a block of aluminum.

Not really.  The Ender 3 is under $200 and with a $50 upgraded hotend, you can print PETG, ABS, and nylon without issue.  I will give you that they are slow.  A lower takes about 18 hours to print, but plastic is also a whole lot cheaper and easier to find than 80% lowers (assuming that's what you mean by castings).

500rds through a PETG lower without any issues is enough for me to call it better than "iffy"

Ok, did not realize what the 80% referred to.

They cost about as much as a 100% lower, but don't require a background check and don't have a serial number making them "untraceable", except whoever you bought them from knows, and for all you know, they work for the government collecting names of people who want "untraceable" guns. Whereas if you cast one from molten beer cans or whatever, and finish it on a mill, nobody knows you have it unless you tell them.

That, and the government could be tracking downloads from sites that host the files to print, or mill gun parts, so...  :rolleyes:

I don't even care about having a super seekrit gun. I already have 3 AR's that I got the regular way. I don't expect to need more than that. If the gummit comes to take our guns, they're going to take more than just the lower receivers, and you're not going to be able to get any of the other parts, either, so unless you can print/machine a complete gun, I don't see the point other than just the novelty of it.

IvanTheTroll is making strides toward complete home production of firearms, including videos on how to electrochemically machine your own rifled barrels.  I believe his model "FCG9" is completely made at home without any "gun parts."
