Abstract

A post-build powder removal system includes a work bed, a platform wall having at least one powder discharge port, and a discharge port sealing system for selectively closing and opening the powder discharge port. The platform wall cooperates with the work bed to define a powder chamber. The discharge port sealing system includes an outer sleeve slidably mounted on an outer surface of the platform wall such that the outer sleeve can slide in a first direction that closes the at least one powder evacuation port and in an opposite second direction that opens the at least one powder evacuation port.

Description

technical field [0001] The present disclosure relates to powder bed fusion additive manufacturing, and more particularly, to a post-build powder removal system for powder bed fusion additive manufacturing. Background technique [0002] Additive manufacturing can be used to create complex articles from a variety of materials. Similar to 3D printing, additive manufacturing typically involves successively adding material layer by layer to build an article, such as a prototype model or a commercial vehicle part. Such articles are also known as three-dimensional (3D) parts or simply parts. Powder bed fusion is an additive manufacturing process used to create parts from metal, ceramic, polymer and composite powder materials. Powder bed fusion is a process that induces the fusion of powder material particles by exposing selected powder material particles to one or more focused thermal energies such as laser, electron beam, and infrared energy. [0003] The powder bed fusion proc...
