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.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
