Powder Bed Fusion Service Process Overview
The powder bed fusion service relies on selectively melting powdered material—commonly nylon or a range of metals—in a powder bed before re-layering and repeating. This melting may be executed by a number of different energy sources, usually laser, electron beam, or a chemical reaction induced by a heat lamp. Powder bed fusion, and additive-manufacturing process, is exceptional at producing overhangs and downward-facing surfaces, especially with plastic, where support structures are not needed. On the downside, the temperatures created by the energy source introduce exceptional heat into the part that may cause warpage or undesirable stress concentration. Parts must sometimes be oriented in counter-intuitive ways during the manufacturing step to reduce heat concentration. This means your design might not necessarily print with Z or Y direction pointed up. Parts produced tend to be quite strong and relatively anisotropic, but with a grainy surface finish, which can be addressed through post-processing techniques such as sanding and polishing.
