Methods for quantifying the stable sintering region in laser sintered polyamide-12 [PDF]

open access: yes, 2013
Manufacturing complex parts by the laser sintering process requires a minimum amount of energy input for consolidation of polymer particles to occur; however too much energy can result in a decline in mechanical properties. This decrease is thought to be
