3D-printed fixtures & jigs
Holding fixtures, jigs, trim tools and metal-forming dies can be expensive elements of post-mold composite part processing and assembly. Additive manufacturing, therefore, is proving especially useful in reducing the design/build time/cost in this area.

Optimum unidirectional compression testing of composites
Dr. Daniel O. Adams, a professor of mechanical engineering, the director of the Composite Mechanics Laboratory at the University of Utah, and VP of Wyoming Test Fixtures Inc. (Salt Lake City, UT, US) discusses the complex relationship between composite tensile and compressive properties, why that makes it necessary to perform both tension and compression testing, and how best to perform the latter.
