SLS Presentation
                     The Evolution of SLS: New Technologies, 
Materials and Applications
Selective Laser Sintering (SLS) is one of the most popular polymer 3D Printing 
technologies for industrial application.SLS has been gradually maturing into a 
technololgy capable of functional prototyping and, more recently, also 
production.

The Evolution of SLS Materials
The first SLS 3D printers most commonly used nylon a popular engineering 
thermoplastic, praised for its lightweight properties, strength and durability. Nylon, 
also known as polyamide (PA), is stable against impact, chemicals, heat, UV light, 
water and dirt, making it ideal for both rapid prototyping and production.

New SLS Materials
The Pace of Development of New Materials for SLS is also Encouraging.
 
Italian 3D printing company, CRP Technology, is perhaps one of the key independent 
developers of SLS materials, famous for its Windform brand. The company offers a 
range of nylon-based composites and rubber-like plastic powders.

Post-processing in SLS
 
While SLS Technology eliminates the need for support structure design and 
removal, it is not without its post-processing challenges. The biggest of them is 
the need to remove the excess powder left on the surface of a part and 
sometimes trapped inside a part.

SLS Applications: A Growing use in Production
While SLS Technology continues to be used in prototyping, increasingly 
it’s also becoming popular for functional part testing, as well as 
production applications.

Aerospace
The aerospace industry, for example, is using SLS to create 
interior parts of the aircraft. The airline is using 3D printing to 
produce aircraft.

Consumer Goods
In the consumer goods industry, Chanel is pioneering the use of SLS 3D printing 
for mascara bruches. Using SLS technology, the design of the brush has been 
optimised, In addition to beauty products, SLS is increasingly used in the 
medical and footwear fields to produce customised insoles and sandals.

Motorsports
 
In motorsports, the technology can help racing teams to innovate car designs and 
test them faster than would be allowed by traditional technologies.

SLS: One of the best choices for 
polymer 3D printing
The SLS 3D Printing market is in a state of continuous Evolution. The 
Technology gets Democratised with the introduction of compact and 
affordable benchtop systems. In the meantime, the manufacturers of industrial 
SLS equipment put a greater focus on solutions that help to establish SLS as a 
production tool.
