There're already companies making weapons for Lego mini-figures:

http://www.brickarms.com/

but they make them by traditional injection molding --- the resolution of 3D printers is still not fine enough to make parts which will properly interchange w/ real Lego bricks (which are made using tons of pressure to a precision of ~10 micrometres).

The brickarms site isn't making their products on a fabrication device though:

from their FAQ:

http://www.brickarms.com/FAQ.aspx

`` I used a 3D parametric modeling program , which produced CAD files. A mold maker then used these files to program a Computer Numerically Controlled (CNC) milling machine to cut cavities into both halves of the mold. When the cavities are ready, he uses an expensive injection molding machine to inject hot ABS plastic (the same plastic used by LEGO®) into the mold with 90 tons of pressure.''

Given that Brickforge has an FAQ which says:

``We are celebrating continuing growth which means shoppers will occasionally find products out-of-stock. To assist customers we have implemented a back-in-stock notification system which allows you to receive an e-mail message the instant an item is back in stock. You should also frequent the BrickForge forums for special stock announcements. We will not respond to correspondence inquiring when certain items are back in stock. Generally, items that are not listed as Limited Editions or retired are restocked within 45 days.''

They also seem to be molding their pieces, not producing them one at a time using a fabricator --- for an example of an on-line company which does this look at www.shapeways.com:

which has a rather limited precision in comparison to Lego bricks:

http://www.shapeways.com/forum/index.php?t=tree&goto=1339&#page_top

``The printer resolution goes to about .1mm, but the material can change it slightly. Overall, .5 should be fine, just make sure that they are not any sort of support walls or they may get broken during shipping or printing.'' .1 mm == 100 micrometers

So I believe you need to retract your claim that I am wrong.

Brick Arms

You're welcome.

Luckily brickarms is there to fill the gap.

For M16s and other assorted modern weapons,go to Brickarms. Unfortunately, they can't seem to keep things from being horribly backordered.

For your modern weapon LEGO needs, I would check out this site: http://www.brickarms.com/Toys/Weapons.aspx

They claim it's made from the same plastic as real LEGOs, but I haven't used them. Anyways they seem pretty cool.

They also happen to make Nazi figurines for your enjoyment: http://www.brickarms.com/Toys/Minifigs.aspx

If you want some Nazis or guns to go with your Legos here you go. From what I've seen very quality build work too. Enjoy!
