Abstract: A method for altering polymer properties for the molding of parts comprises exposing, to a scission-causing stressor, a region of a polymer form. The scission-causing stressor is controlled to achieve, in a relatively higher molecular-weight polymer at the region, an amount of scission that results in a reduction in the molecular weight of the relatively higher molecular-weight polymer, thereby forming a relatively lower molecular-weight polymer at the region.

Then, after the n+2th powder layer is formed, the unsintered part is sintered together with the n+2th powder layer.
