Perfect for producing large quantities, of small parts, in real thermoplastics.

SLS (Selective Laser Sintering) or LS (Laser Sintering) is ideal for creating parts in actual Polyamide; Nylon 12, Glass Filled Nylon and TPU elastomer parts.

BuildParts utilizes sPro 60 digital high-def, high-speed sintering machines, which produce fine features, smoother surfaces and thinner walls than most other service bureaus. SLS plastic parts in most cases are used in AM (Additive Manufacturing), partly due to the speed in which the process can create multiple pieces at one time, as well as, the strength and thermal resistance the parts offer.

For larger production needs and single piece parts up to 27.6 x 15 x 22.9 in (700 x 380 x 580 mm), BuildParts has recently added multiple EOS P770 machines. These offer fantastic a surface finish with incredibly fast build speeds. 

This method of building parts allows for complex wireframe and assemblies to be built with precision and speed. The part may be used as is, or further processed with a sealant for water or air tight applications.  It is not uncommon (like with the FDM process) to find parts produced in these high heat deflection materials, in the engine bay of a vehicle for testing.

Great for; Durable Prototypes, Additive Manufacturing, fit and function models that do not require an ultra smooth surface directly off of the machine.  Parts can be dyed or sanded, primed and painted. SLS/LS are superb for snap fits, tabs or living hinges in Duraform PA, without the need to infiltrate to final part.

  • Chemical resistence & excellent heat deflection for parts that also require durability.
  • Because many parts can be stacked vertically during a build, SLS and LS are both optimal methods for producing large batches of parts in one production run.
  • Parts can be extremely inexpensive when ordered in large quantities.
  • SLS; PA and EX offer fantastic living hinges and create a nice durable, yet somewhat flexible, rigid part.
  • Glass Filled (GF) Nylon is the most common material choice , but non filled is available.
  • Great for; DDM, fit and function models that do not require an ultra smooth surface.
  • Typical Lead-times are 3 to 6 days.
  • Selective Laser Sintering (SLS)

    This excerpt from our Building the Miller 91 video, highlights and describes the SLS process in detail.

  • EOS P770's

    BuildParts operates multiple large format EOS P770's, as well as, High-Definition/High-Speed sPro60 SLS machines. The HD option enables us to produce parts with much finer feature details, as small as 0.015".

  • SLS is the ideal manufacturing process for large volumes of parts, as well as, complex wireframes and assemblies.
