Selective Laser Sintering (SLS), SLS Prototype
Selective Laser Sintering (SLS) is a process by which YinHua creates 3D
SLS prototypes by fusing or sintering powdered thermoplastic materials
or metals to form functional prototypes. YinHua is a premier selective
laser sintering service company. An advantage to using SLS is the range
of materials that can be used, including nylon, metals, and elastomers.
Rapid prototype (RP) laser sintering can provide a competitive edge in
your product development by producing rapid plastic or metal SLS
prototypes with complex shapes that closely resemble injection-molded
Technical Overview of Selective Laser Sintering
In the Selective Laser Sintering (SLS) process, three-dimensional parts
are created by fusing (or sintering) powdered thermoplastic materials
with the heat from an infrared laser beam. The objects creation is
accomplished by repeatedly fusing thin powder layers using a laser beam.
This additive manufacturing sequence produces parts that gradually
increase in size until they reach the prescribed dimensions. These
prototypes are created directly from 3D CAD models.
Unlike stereolithography, SLS prototyping techniques allow prototypes to
be made with material properties closer to that of injection molded
pieces (using the DuraForm or DuraForm Glass Filled material). In
addition, SLS has the capability to make metal prototype parts using the
Rapid Steel A6 or Laser Form ST-200 (which replaced ST-100) materials,
where metallic powder is used in the laser sintering process. Building
parts out of Somos 201 material gives a final SLS prototype made from a
durable elastomer selective laser sintering material, ideal for bellows
and gaskets. YinHua uses the most advanced selective laser sintering
materials and can provide assistance in their selection.
Another advantage is that there is typically very little (if any)
processing required after the selective laser sintering is completed.
