Selective Laser Sintering (SLS)
For Low Volume Batch Production of small parts in 3D Printing
SLS is a powder-based 3D Printing technology used for parts having highly complex and intricate geometries. It finds applications in low volume batch production in 3D Printing. Snap-fits and moving-part assemblies can be fabricated in one single go in SLS. SLS is known for its rapid production of fully functional end-use parts.
Data That matters
SLS can be used for parts ranging from 1 to 100-200 numbers depending on part size. SLS is economical for Low volume production of small parts (< 100mm).
The industry standard layer thickness in SLS technology is 100µm which results in parts having geometries that are true to their 3D CADs. A human hair is about 75µm in size.
SLS is a faster process as compared to the other 3D Printing processes. The lead-time for SLS orders is 3-4 business days. Any post-processing (finishing/painting/dyeing) operations would add another 1-2 days to the project timelines.
Maximum Part Dimensions
The maximum part size that we can manufacture in SLS is 340 x 340 x 600 mm.
Since SLS is a powder-based technology, the parts have an inherent grainy surface finish. The surface finish can be improved by vibratory-polishing the parts.
Owing to the powdery nature of the raw material, painting the SLS parts is a tricky job. Instead, SLS parts are usually dyed. The dye gets absorbed on the surface without leading to any dimensional inaccuracy.
