Abstract 3D printing, more formally known as Additive Manufacturing (AM), is already being
adopted for rapid prototyping and soon rapid manufacturing. This review provides a brief …

Powder bed fusion (PBF) is one of seven different classes of additive manufacturing (AM)
technologies identified by ASTM and ISO. In polymer PBF, an infra-red energy source …

Powder-bed fusion is a class of Additive Manufacturing (AM) processes that bond
successive layers of powder to facilitate the creation of parts with complex geometries. As …

With the evolution of additive techniques from prototyping tools (Rapid Prototyping; RP) to
the production of actual end-use parts (Additive Manufacturing; AM), there is a growing need …

This work examines one polyamide 12 (PA12) powder grade but in different re-using states
(ie, virgin, aged-virgin mixed, and in-process aged powders) for selective laser sintering …

Commercial laser sintering (LS) machines have been used for years in a variety of rapid
prototyping applications. Emphasis in the LS research community has moved towards rapid …
