Autodesk acquired Moldlow last year and clearly is injecting digital firepower into the simulation software company founded by Colin Austin in Australia in 1978. Simulations are now delivered more than two times faster with a parallel architecture using NVIDIA Quatro FX 4800 and Quatro FX 5800 GPUs, says Hilde Sevens, senior product line manager for the Manufacturing Solutions Division of Autodesk, San Francisco. One of Autodesk’s goals is to improve accuracy of cavity simulations by providing better 3D mesh analysis. Moldflow will also be better integrated with Autodesk Inventor and other CAD models. The improvements are contained in the Autodesk Moldflow 2010 release demonstrated at the National Plastics Exposition this week in Chicago. One of the company’s big goals is to make Moldflow part of the design process at the very beginning. Many designers now use Modlflow to verify a design prior to cutting a mold. The idea is to save time and money, says Sevens. One strategy is to encourage more use of Autodesk Moldflow Adviser, a simplified and less expensive tool than Insight. Release 2.0, scheduled for next month will beef up digital prototyping options.
Meanwhile, Moldflow continues to expand its capability to test compounds, both commercial and proprietary. Simulations are developed in part from actual materials testing. Moldflow has a database of more than 8,000 commercial grades and a separate highly guarded database of more than 4,000 formulations developed for specific customer applications. A current focal point is developing improved simulation capability for long glass-fiber reinforced systems due to increased effort to cut weight in cars. As of now, there has been little customer demand for simulation of biobased materials. That may change, however, as big resin producers, such as DuPont and BASF roll out bio grades.
HP revealed more of its 3D printing plans in a recent webinar. Senior vice president of inkjet and graphics solution business Stephen Nigro spoke about how the technology works and expanded on HP's vision of open collaboration to commercialize its Multi Jet Fusion 3D printing technology for end-production, and open collaboration on new materials. He also said HP will create software to help users decide when to use Multi Jet Fusion versus conventional subtractive manufacturing.
A lightweight electric urban concept car designed by several European companies weighs only 992 lb without its battery. It would have weighed 26.7 lb more if its windows were made of glass instead of the specially coated LEXAN polycarbonate resin from SABIC Innovative Plastics.
Skylar Tibbits' team in MIT's Self-Assembly Lab is now 4D printing self-assembling shapes made of programmable carbon composites and custom wood grain. The composites are being used in a sport car airfoil, and the wood grain is beautiful.
The NanoSteel Company has produced high-hardness ferrous metal matrix composite (MMC) parts using a new nanosteel powder in a one-step 3D-printing process. Parts are 99.9% dense, crack-free, and with wear resistance comparable to M2 tool steels.
