Gun enthusiast uses 3D printer to make working M16 assault rifle

In one of the latest dramatic developments in the series of experiments to uncover the capabilities of 3D printers, Michael Guslick, a firearm enthusiast who goes by the screen name HaveBlue, has printed and successfully fired part of an M16 assault rifle, using a decade-old Stratasys printer and materials costing between $30 and $50.  Sync.ca blogger Rhonda Callow reports the details she derived from a forum on the firearm-resource Web site AR15.com in her July-28th post, entitled "Oh great, now your friendly neighbourhood psycho can print his own guns".

Besides generating plenty of on-line discussion, both pro and con, Callow’s post provides an interesting link to Shapeways.com--a Web site enabling its members to sell products made by 3D printing, as well as learn how to design and make them.
