The National Institute of Standards and Technology has developed three ASTM International standard test methods for the thin films used to make micromachines (MEMs). Published in The Annual Book of ASTM International Standards, the test proceduresófirst such standards in the worldócould faciliate global commerce in MEMs by enabling reliable measurements of MEMs devices. Detailed instructions are given for measuring thin-film dimensions and strain. For more info, go to www.eeel.nist.gov/812/test-structures.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
