The past decade has seen increased prominence for new, more sustainable production methodologies. Selective laser sintering (SLS), an additive manufacturing (AM) technology, is one of those upcoming production methodologies, but its end products suffer from inconsistently reproducible properties. Ph.D. candidate Prakhyat Hejmady from the TU\/e Department of Mechanical Engineering has developed an experimental methodology which can offer new possibilities in tailoring this production technique. He defended his Ph.D. thesis on 4 February 2021.<\/p>\n

The advent of AM, also commonly known as 3-D printing, has enabled manufacturing of complex and intricate designs without the constraints imposed by traditional manufacturing techniques. SLS is a powder-based AM technique, were products are manufactured layer by layer, using laser as a heat source to locally fuse polymeric powder particles. AM’s design freedom both shortens the development cycle and significantly reduces material waste, making it a sustainable alternative. Manufacturers of every size view it as a complement to existing, traditional manufacturing methods. <\/p>\n

New materials<\/b><\/p>\n

To transition from prototyping to widespread mass manufacturing, optimization of SLS is still needed. The current SLS process lacks in reproducibility and is limited by the low availability of usable material types. This limits its use in producing parts with the desired mechanical and functional properties. Therefore, new materials have to be explored, for which the process conditions have to be optimized accordingly. Currently, the optimization process is done on a trial basis, with little to no information on the underlying mechanism during the laser sintering process.<\/p>\n
