Description
Lanti Yang, Hao Gu, and Zahir Bashir present a way to laser-print polymer parts at low bed temperatures in this 2024 paper. Laser sintering fuses powder layer by layer into solid parts. Most machines cap the bed at two hundred degrees. High-melting plastics like PET need more heat than that. Printing them cold causes curl and warping that wreck parts. Their trick prints an anchor film in place first.
The film grips the part by friction and blocks the curl. PET parts then printed cleanly at far lower bed heat. No machine stoppages interrupted the builds. The method opens common machines to stronger plastics. It also saves the energy a hotter bed would use. The paper is a manufacturing methods report.
