"Agreed.  The gun issue is simply media sensationalism, since many who write about it don't really understand the technology.  While the potential is a concern, i.e., plastic guns that go undetected, these "guns" have not…"

Donald Murray commented on Leslie Langnau's blog post What is your biggest frustration with 3D printing?
"3D printing has been around for 20 years and all this commotion over the 3D gun which doesn't even fire well, is mute. 3D printing is responsible for our rapid prototyping today and vital for medical on-demand instruments for surgury. So, just…"

What it takes to achieve a low cost desktop 3D printer for engineers

The question of when will more engineers use 3D printers may be answered this way—when the price per prototype drops, some say to as far down as less than $1.00 a part. At least that’s what Ezra Zygmuntowicz, CEO, founder, and “hacker” (his words) at Trinity Labs thinks. I met Ezra at the recent MD&M West show in Anaheim, CA. He was displaying his new prosumer 3D printer in the PBC Linear booth.…See More

What is your biggest frustration with 3D printing?

Posted on March 7, 2013 at 5:42am 4 Comments

Despite the media hype that 3D printers can be used to make literally anything, and that they will disrupt all kinds of present day processes and systems, professional users have a number of frustrations with this technology. These frustrations can be overcome with further R&D, assuming the media hype doesn’t inflate expectations to a point that frustrates the most enthusiastic users. But here are some of the frustrations shared by experienced users on various sites:

Geomagic Freeform 3D scanning software was used to render the face of King Richard III.

The story of the remains of King Richard III has been in the news lately.  It's interesting that the historical record was fairly accurate.  But did you know that 3D scanning software helped verify some of that historical information?  http://www.makepartsfast.com/2013/02/4951/geomagic/

Constructing a Cubesat using additive manufacturing

Posted on August 23, 2012 at 11:21am 0 Comments

The use of Windform® XT and additive manufacturing (AM)/3D printing (3DP) technology demonstrates the fast adaptability and freedom of design possible in nearly any field. For the developers of the RAMPART Cube Sat, the use of this material and technology enabled them to modify, change, and add experiments without concern for having to develop tooling or modify an existing cube structure.

"Hobby machines" already produce better prints, in many cases, that Stratasys equipment.  Print a goblet on a Dimension machine and try to drink from it some time.  :-)
