Materials List

Materials Type
Thermoplastic Polyurethane (TPU)
TPU Rubber
As a strong, wear-resistant and elastic substance, SLS TPU X92A-1 offers new application opportunities. Thanks to its convenient processing window and full recyclability of the powder cake, it is a natural choice for series production; tailor-made shoes and clothes, complex tube geometries or orthopaedic parts are some examples of new 3D print applications.
Polystyrene (PSB)
Polystyrene (PS)
This foamed white, amorphous or semi-crystalline thermoplastic has medium hardness and low impact resistance. 3D-printed parts made from PS are used to make master models for vacuum, plaster and ceramic shell castings.
Glass-filled PA 6
PA6GF has exceptional mechanical strength and heat resistance over 200℃ which is much better than PA 12. It's the ideal material for functional prototypes or end-use parts.
PA11 White
Nylon 11 is a high-performance, bio-based nylon material for functional prototyping and small batch production. It has better flexibility than PA12, and it's suitable for printing parts that need to bend or resist impact.
FormLabs PA 12 Grey
Balancing strength and detail, Nylon 12 is a highly capable material for both functional prototyping and end-use production of complex assemblies and durable parts with high environmental stability.
PA 12 White

The material is a White polyamide 12 with high-temperature resistance, good toughness, and high strength, which suitable for functional verification of product prototypes.

PA 12 Black

The material is a polyamide 12 with high-temperature resistance, good toughness, and high strength, which suitable for functional verification of product prototypes.

Glass-filled PA 12

Glass bead-filled polyamide 12 powder with a combination of excellent rigidity and good elongation at break.

Polypropylene (PP)
PP GB (Glass-Bead)

PP (Polypropylene) is one of the most widely used materials in conventional manufacturing and can now be used in 3D printing technology! BASF Forward AM PP-GB offers high toughness, excellent chemical resistance, structural tightness and low moisture absorption.

Our SLS manufacturing standards

We manufacture your parts according to strict manufacturing standards. A verification of these requirements is included in our inspection report that is shipped with every order.


  • A dimensional accuracy ± 0.20 % with a lower limit of ± 0.20 mm 

  • Consistent surface finish with no bumps or delamination.


Post processing for SLS 3D Printing

Standard (no additional post-processing)
  • With 3D printing technologies that use materials in powder form, such as Binder Jetting and SLS, the post-processing stage begins by first removing unused powder. This is then followed by either surface finishing operations and light polishing,

  • All printing parts is clean and dry as a standard post- processing work without extra charges before shipped out


Features Add-Ons Post processing for SLS

Additional post processes can be applied to improve the appearance or mechanical properties of parts produced with SLS.

See Full add-ons post processing and surface finishing work.
Add-ons post processing for the SLS Printing
  • Painting

  • Spraying

  • Hydro-Dripping

  • CNC Precision

  • Treading

  • Tapping

  • Sanding
