High speed sintering (HSS) is an additive manufacturing (AM) process that creates parts by sintering powder particles using inkjet and infrared (IR) lamp technology rather than laser systems employed in laser sintering (LS). This research investigated the effects o f machine parameters (lamp speed, bed temperature) and the addition o f fum ed silica flow agent on the tensile properties o f thermoplastic elastomer (TPE) parts processed using HSS. The results showed improved elongation at break (EaB) values by a factor o f more than 2 x compared to reported values fo r LS o f the same TPE. A t constant parameters, improved tensile strength and tensile modulus were observed with the addition o f flow agent into the sintering mixture.
For the last twelve years, his research has been primarily concerned with applied inkjet printing. His group at Sheffield undertakes funded research into reactive inkjet printing, controlled crystallisation and polymer printing. Other research interests are involved with drying behaviour, inkjet used in tissue engineering, printed electronics and additive manufacture.Adam Ellis received his Masters (2007) and PhD in Chemistry (2011) from the University of Sheffield. He was then an EPSRC doctoral prize fellow before moving to the Department of Mechanical Engineering to join the Centre for Advanced Additive Manufacturing at the University of Sheffield in 2012. Adam worked as a post-doctoral research associate until 2016 when he joined Xaar as project manager for 3D Services.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
