Freeman Technology is pleased to announce the release of ‘Polymers for 3D Printing’.
Selective Laser Sintering (SLS) is an additive manufacturing technique typically used for rapid prototyping and low volume production of functional components. The process employs a laser beam to sinter powdered material, binding it together to create a solid structure. The laser fuses pre-defined areas of a powder bed by scanning cross-sections generated from a 3D digital description of the part. After each cross-section is scanned, a new layer of material is applied on top.
Generating these layers is a precise process and requires a feedstock that can be reliably distributed by the delivery system without agglomerates and voids. This study used the FT4 Powder Rheometer to evaluate three samples of Polyoxymethylene (POM), two of which contained different additives, to identify clear and repeatable differences which rationalised in-process performance.
A copy of the application note is also available in Chinese, German and Japanese. Please scroll to the bottom of the page to download.
