The University of Exeter’s (Exeter, U.K.) Centre for Additive Layer Manufacturing (CALM), in collaboration with Victrex (Cleveleys, U.K.), is one of the first to commission the recently launched EOS P 810 laser sintering additive manufacturing (AM) platform, for use with Victrex high-temperature polyaryletherketone (PAEK) polymers.
The goal of the partnership is to introduce next-generation Victrex PAEK polymers and composites while improving the performance of the underlying AM processes. The university says investment in the new EOS P 810 platform is expected to accelerate the commercialization of AM for high-performance parts.
“We can now further our research by utilizing the next generation of high temperature systems, the EOS P 810,” says Professor Oana Ghita, the lead of CALM at the University of Exeter. “The new equipment allows us to link the fundamental research with the commercial manufacturing process, to optimize the materials and their application, while accounting for the new thermal, optical and mechanical upgrades and providing us with accurate insights into the detailed dynamics of laser sintering.”
The EOS P 810, which has a build volume of 700 by 380 by 380 millimeters and two 70-watt lasers, is capable of printing with materials that have melting temperatures around 300°C. According to Victrex, it is suitable for the low-melting-point PAEK polymers the company has designed and optimized specifically for AM.
“This is an exciting milestone in our collaboration with the University of Exeter, which we announced in 2018, creating an effective eco-system to accelerate the commercialization of AM materials for performance parts to meet customer needs,” says Ian Smith, Victrex director of innovation.
There are numerous methods for fabricating composite components. Selection of a method for a particular part, therefore, will depend on the materials, the part design and end-use or application. Here's a guide to selection.
