What is SLS?
Selective Laser Sintering (SLS) is a powder-based 3D printing technology. It makes use of a high powered laser that selectively scans a thin layer of powder and sinters the small powder particles together to form 3D object, layer by layer.
Unlike most other additive manufacturing technologies, SLS does not require any form of support as the leftover unsintered powder acts as self supporting material. Thus, extremely complex geometries are made possible.
The technology is a great choice when 3D printing functional prototypes as SLS printed parts are robust and will not become brittle over time. In fact, durability of parts created with SLS technology is on par with those produced through traditional manufacturing methods such as injection moulding.
In comparison to MJF, SLS also has more material options.
Other 3D Printing Processes
Short for Fused Deposition Modeling, FDM is one of the most commonly adopted additive manufacturing technologies today due to its low cost and efficiency.
Stereolithography was first developed in the 1980’s. The process is often used when a smooth finish and high accuracy is required.
Polyjet is a liquid-based 3D printing technology. It is able to 3D print at a high speed, with extremely high accuracy and a smooth surface finish.
Similar to SLS, Multi Jet Fusion also utilizes powder to 3D print objects. Parts produced by MJF are stronger and more precise compared to SLS.
Full Colour 3D UV-Curable Inkjet technology has the capability to print 10 million colours, making it ideal for products such as marketing models.
