That will surely stop him (and others).

surely not although, I don't see the point to use a 3d printer there. an advanced CNC routing machine will make better gun parts.

  If this is about the affordability of 3d printers, couldn't a desktop CNC machine do something similar? You can buy one on amazon.com for $350-ish: http://www.amazon.com/Zen-Toolworks-CNC-Carving-Machine/dp/B002ARTLUG%3FSubscriptionId%3DAKIAILSHYYTFIVPWUY6Q%26tag%3Dduckduckgo-z-20%26linkCode%3Dxm2%26camp%3D2025%26creative%3D165953%26creativeASIN%3DB002ARTLUG http://www.amazon.com/Zen-Toolworks-CNC-Carving-Machine/dp/B... I don't know if it would be adequate, but it has a working space bigger than some pocket pistols for sale today. Guns are relatively simple machines with forms existing for a century still sold new today. Such as bolt action rifles.

    1.) That's about a thousand dollars short of a functional CNC mill. NOT INCLUDED - This is just the CNC machine with motors. You will need a 3 Axis Stepper Motor Driver to manage each motor, a spindle/cutter (a Dremel would work) and a DC power supply for the driver. You will also need a computer with a standard printer port and CNC software. - You will also need a way to mount and secure the spindle/cutter tightly to the Z-axis plate on the machine. 2.) It can't mill metal. 3.) A mill's the wrong tool for a barrel. You'd use a lathe for that, and even then it'd be smoothbore, without the tool to cut rifling.

      re 3) the only regulated (in US) gun part is the lower receiver which looks like this: http://www.thingiverse.com/thing:11669 http://www.thingiverse.com/thing:11669 A mill is the right tool for that (though, it's tricky and some manual work will be required) A barrel is available for online purchase (in US) No problem here. For other countries, with stricter gun regulations, like Russia, making a barrel would be a problem, but it's usually solved with a Deep Holl Drill (using a steel rod or cylinder as a source)

  To make something with a 3d printer you just need a volume model of it. To make something with a CNC router you typically need to create a routing program, which is a lot more difficult.

    3d printed gun (at least, at this moment) does not last more than one shot. And even this shot is more risky for the fighter than for the target. Also, I don't buy the argument about a difficulty to create a routing program. One can create it, others will just download and use.

Stratasys doesn't care about stopping him - they just don't want their company's name on it.

  There's probably legal concerns on their part as well: gun manufacturers get sued. A lot. By government departments, by victims of gun crime, lawsuits both genuine and spurious. If you're a manufacturer of 3D printers you can probably think of much, much better ways to spend your money than defending or settling a lawsuit against you. If this guy wants to actually go ahead with his project he's probably going to have to accept he'll need to buy the printer rather than lease it.
