The hidden promise and challenges of selective laser sintering for plastic 3D printing

Despite its decades long history, selective laser sintering (SLS) continues to have undeveloped potential to form high quality production parts that are difficult to make using other 3D printing methods. One of the largest challenges to 3D printing of production quality plastic parts is poor mechanical properties commonly observed as reduced strength in the z-axis. Although companies such as Essentium and Rize3D have attempted to overcome these limitations with novel modifications on fused filament fabrication (FFF) and Carbon has demonstrated improved mechanical properties in a method similar to stereolithography (SLA), these companies are unique in offering more mechanically isotropic […]
