Many engineers find it difficult to utilize additive manufacturing because of a lack of “Design for AM” knowledge in the public domain. Reliable information on material properties and geometric specifications is often scattered throughout the literature, if it is publicly available at all. The objective of this research is to create design guidelines for dimensioning parts that are additively manufacturing using powder bed fusion technology, particularly selective laser sintering (SLS). The guidelines are based on a series of experiments designed to determine the limiting feature sizes, accuracy, and repeatability for various types of features fabricated in commercially available SLS machines. The features include concentric rings, rods, slots, holes, letters, and snap-fit assemblies, plus mechanical properties and surface finish. Statistical data is gathered from multiple machines, orientations, and locations within the build chamber. The result is one of the largest publicly available databases on design allowables for any additive manufacturing process.
