xPA12

xPA12 QLS 350 Powder is a durable nylon plastic that can be used for a wide range of applications, both for prototyping and for end products. Printed using Quantum Laser Sintering (QLS), when thin, it’s flexible enough for hinges and springs and when thick, it’s strong enough for structural components.

Typical applications of the material are fully functional parts with high end finish right from the process, which easily withstand high mechanical and thermal load.

xPBT

Nexa3D xPBT is the first-ever PBT powder commercially available for selective laser sintering. The material is the ideal solution for small series production via additive manufacturing in industrial applications such as automotive electronics.

  • Well-known material with dielectric properties
  • PBT powder for selective laser sintering

xPBT is the fi rst material from DSM’s powder platform, offering customers a widely-known material in the industrial sector which can now be considered for small series production of end use parts.

As 3D printing evolves from prototyping to industrial manufacturing, customers need materials such as xPBT to meet their stringent demands. Current solutions do not meet application requirements for industrial applications, such as automotive electronics or applications that need to perform under high temperatures. xPBT has the same dielectric properties as material used in injection molding processes, making it a material engineers are familiar with and prepared to use.

Developed for a wide sinter window, the powder is extremely easy to print. Additionally, xPBT is environmentally friendly with a high reuse rate and is recyclable to the extent that the material can be brought back to the powder bed process.

Key Benefits
  • A well-known material that can be adopted quickly
  • Excellent dielectric properties
  • Extremely easy to print
  • Improved dimensional stability due to lower moisture uptake
  • Less waste due to >60% reuse rate
  • Recyclable: non-reusable material can be brought back to the powder bed process
Applications
  • Connectors
  • Automotive Electronics
  • Electrical
  • Lighting
