Jim, I noticed the same things about the article. I included the link as an example of what's out there. If you Google "PLA and 3D printing", you''ll come up with a lot of other sources, some of which have a very different take. Beth's article says "PLA was chosen because of its strength and ability to make very large prints without cracking or warping."
Gosh, Ann – That article is less than encouraging as an endorsement for PLA. It actually says it is best used as the support-structure for the primary material being ABS; that the PLA will degrade away, leaving the host ABS in place. The article is about 2 years old. I'm hoping that if MakerBot has invested their product line on this material as the primary building block, that it has rugged, stable material characteristics. Guess the Jury's still out.
Beth, I notice that the Replicator 2 uses bioplastic PLA, not ABS. This appears to be an emerging trend in additive manufacturing, at least at the higher end. Do you know of any other 3D printers that use bioplastics?
The Business Advantage Group recently released its 2014 Worldwide CAD Trends Survey, announcing both a prospective increase in the cloud-based CAD industry and the anticipated incorporation of 3D printing.
Autodesk, a leader in 3D design solutions, announced earlier this month that it has completed its acquisition of Delcam, a leading supplier of CAD/CAM manufacturing software, in its efforts to expand the company’s manufacturing software capabilities.
Texas Instruments' Webench is vying to win the Golden Mousetrap Award in the Analysis & Calculation Software category, but it is up against some pretty tough competition from Mentor Graphics, COMSOL, and aPriori Inc.
