3D Printing News Unpeeled: Highly Entangled Polymer Networks

University of Pennsylvania, the University of Colorado, NIST researchers have have developed a way to make better performing DLP materials. In the paper, "Additive manufacturing of highly entangled polymer networks" they outline a process where photoinitiators and a redox process have been used to make with highly entangled long polymer chains out of monomers. This could lead to new elastomeric or hydrogel parts that could be used as wound dressing. 

Researchers from the Department of Energy, NNSA Center of Excellence CAMCSE, UAB, University of Massachusetts-Amherst, the University of California-Irvine, and the University of Notre Dame have shown that a high eutectic high-entropy alloy, Ni40Co20Fe10Cr10Al18W2, which shows remarkable strength under pressure. 

A number of 3D Printing firms got part of a nine year $975 million contract with the United States Air Force to support the Rapid Sustainment Office (RSO).
