Overview of materials used in SLS technology

Selective laser sintering (SLS) technology has gained wide acceptance in industrial manufacturing due to its versatility and ability to use a variety of materials. Here is an overview of the key materials used in SLS, with particular emphasis on the PA12 polymer and its variants. Technology Applied – the largest Polish company providing 3D printing services, bases its offer largely on selective laser sintering, using all the materials listed below.

PA220 (PA12) – is the most popular material in SLS technology, valued for its increased strength properties and resistance to cyclic loads. As the most universal material in 3D printing using SLS technology, PA220 allows you to create prototypes, utility items and functional parts. Resistance to chemicals and the ability to operate at temperatures up to 70°C make it a versatile option for use. Polyamide is white by default, but can be dyed any color. Dyeing methods include immersion dyeing, which offers color durability but a limited color palette, and spray varnishing, which allows you to choose any color from the RAL palette. Technology Applied has its own paint shop that allows you to dye parts in virtually any color.

TPU 1301 is a flexible material with high extensibility and elasticity. Its ability to elongate up to 200-250% and excellent shock-absorbing properties make it ideal for applications requiring flexibility and elasticity. The possibility of dyeing additionally increases its attractiveness. PA 3200 GF is a glass-reinforced polyamide that offers increased stiffness and durability. Glass balls increase abrasion resistance and allow operation at elevated temperatures. It is ideal for the production of rigid parts and components operating in difficult conditions.

PA2241 FR is a specialized, fire-resistant material based on polyamide, intended for the aerospace industry and electronic applications. Compliant with UL94 V-0, PA2241 FR provides FAR 25.853 Aerospace Class flame retardancy, halogen-free. Alumide is a unique blend of polyamide and aluminum, characterized by increased stiffness and a characteristic gray color. Alumide allows processing such as grinding and polishing, and its good thermal conductivity and high sinter density make it ideal for high temperature applications.

In summary, the variety of materials available in SLS technology, from PA12 to Alumide, opens up new possibilities in industrial production, enabling the creation of parts with specific properties and applications. The use of these materials in SLS gives manufacturers the flexibility, strength and precision necessary to create innovative and functional products.
