What is your biggest frustration with 3D printing?

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:

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.…
