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.

Materials

SLS Buckle

PP

Short for Polypropylene, PP is a thermoplastic “addition polymer” made from the combination of propylene monomers.

SLS PA12 (White)

PA12 (White)

White PA12 material for slightly more translucent parts. High strength and stiffness and various finishings possible.

PA12 (Grey)

A Polyamide 12 powder (nylon based compound) with good mechanical properties and excellent surface resolution.

TPU Flexa Black

TPU material for producing flexible parts. Similar properties to rubber, suppresses hits and shocks well.

Glass-Filled Nylon

Glass-Filled Nylon

Glass filled Nylon (SLS) contains glass particles that give parts high stiffness and improved thermal and abrasion resistance over standard Nylon.

Other 3D Printing Processes

FDM

Short for Fused Deposition Modeling, FDM is one of the most commonly adopted additive manufacturing technologies today due to its low cost and efficiency.

SLA

Stereolithography was first developed in the 1980’s. The process is often used when a smooth finish and high accuracy is required.

Polyjet

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.

MJF

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

Full Colour 3D UV-Curable Inkjet technology has the capability to print 10 million colours, making it ideal for products such as marketing models.
