In Material Extrusion (FDM), we can now use inexpensive machines to make dimensionally accurate & tough parts in various materials at low cost. These parts can fulfill many industrial and manufacturing applications bar one glaring defect.

Material Extrusion (FDM) parts are often ugly, and layers can be seen on the rough parts. FDM parts and materials are improving all the time; parts are getting smoother and better looking out of the machine. Clusters of FDM machines bring throughput and versatility and have begun to be used to manufacture parts at scale.

With Selective Laser Sintering (powder bed fusion), one can make thousands of individual parts in many different geometries. Highly detailed polyamide SLS parts have been used for tens of thousands of surgical guides and have found many industrial applications. All parts have to be depowered and cleaned of excess powder, however. Additional steps, such as mechanical finishing are […]
