Selective laser sintering (SLS) is an industrial 3D printing process that produces accurate prototypes and functional production parts in as fast as 1 day. Multiple nylon-based materials and a thermoplastic polyurethane (TPU) are available, which create highly durable final parts that require heat resistance, chemical resistance, flexibility, or dimensional stability. With SLS 3D printing, no support structures are required making it easy to nest multiple parts into a single build and an economical solution for when higher volumes of 3D-printed parts are required.
Common uses for selective laser sintering are:
- jigs and fixtures
- housings
- snap fits and living hinges
Selective Laser Sintering (SLS) Materials
PA 12 White
expand_less expand_morePA 12 White is an economical material choice for functional prototypes and end-use parts. It offers high impact and temperature resistance, is very durable, and remains stable under a range of environmental conditions. The nylon material exhibits a white finish with a slightly rougher surface texture compared to other nylons.
Primary Benefits
- Strength and stiffness
- Well-balanced material properties
PA 12 Glass Filled White
expand_less expand_morePA 12 40% Glass-Filled is a polyamide powder loaded with glass spheres that add stiffness and dimensional stability. The material possesses higher thermal resistance than unfilled polyamides and exhibits excellent long-term wear resistance. Due to the glass additive, it has decreased impact and tensile strengths compared to other nylons.
Primary Benefits
- Stiffness and dimensional stability
- Long-term wear resistance
- High-temperature resistance
PAx Natural
expand_less expand_morePAx Natural is a versatile polyamide which is characterised by excellent toughness and flexibility in any direction, including the z plane. The material possesses great long term stability and durability and can be used to produce both prototyping as well as end-use parts.
The material is very versatile, so applications range from living hinges and snap fits to fixtures, enclosures as well as orthotics.
Primary Benefits
- Excellent toughness and durability
- High impact and high elongation
- Long-term stability
PA 12 - Carbon Filled Black
expand_less expand_morePA 12 Carbon-Filled is an anthracite grey nylon characterised by extreme stiffness and high-temperature resistance, coupled with electric conductivity properties and lightweight. It can be used for both functional prototypes and end-use parts. The carbon-fibre filler provides different mechanical properties based on the considered three-axis direction. This material exhibits a good surface quality and smoother finish compared to other SLS nylons.
Primary Benefits
- Extreme stiffness
- Electrical conductivity
- Excellent long-term stability
PA 12 Flex Black
expand_less expand_morePA 12 Flex Black is a black / anthracite nylon characterised by excellent flexibility and impact resistance. PA 12 Flex Black combines positives properties of PA12 and PP. Strength and stiffness is similar to PA 12. The elongation is comparable to that of unfilled PP. Its high durability makes it an excellent choice not only for prototyping, but also for end-use parts.
Primary Benefits
- High elongation at break
- Flexibility
- Durability and toughness
TPU-88A Black
expand_less expand_moreThis thermoplastic polyurethane (TPU) combines rubber-like elasticity and elongation with good abrasion and impact resistance. It can be leveraged to produce both prototypes and functional parts. The material’s rubber-like quality is ideal for seals, gaskets, grips, hoses, or any other application where excellent resistance under dynamic loading is required.
Primary Benefits
- Tear and abrasion resistance
- Flexibility
- Durability
