Rapid Prototyping with Selective Laser Sintering (SLS)
PERIDOT provides services for the most advanced laser fusion technique: SLS. This process creates a prototype from a thin layer of nylon coated with a thermoplastic binder by scanning the surface with a laser beam, fusing the polymer and bonding the particles. The rest of the layer remains as a loose powder. The first layer is then lowered and a new layer is bonded to it. This process repeats until the component is complete.
Selective Laser Sintering creates solid, three dimensional objects by fusing powdered materials with a CO2 laser. Once the 3D CAD data is sliced in the software and downloaded, the SLS process can begin. As the process begins, a layer of heat-fusible powder is deposited across the part build chamber. An initial cross-section of the object under fabrication is selectively 'drawn' on the layer of powder by a heat generating C02 laser. The interaction of the laser beam with the powder fuses the powder particles to form a solid mass. An additional layer of powder is deposited via a roller mechanism on top of the previously scanned layer. The process is repeated, with each layer fusing to the layer below it until the part is complete.
SLS uses polymer powders which, after sintering, approximate thermoplastics. A variety of thermoplastic materials such as nylon, glass filled nylon, and polystyrene are available. PERIDOT typically provides SLS rapid prototypes using Duraform or Glass Filled Duraform materials.
SLS rapid prototype products are less prone to the residual stresses from long-term curing and environmental factors. SLS materials are easily machined and are easier to bond if sectioning of parts is required.
As a flexible engineering service bureau, PERIDOT offers unique customer service and new and creative ideas. We can also provide secondary operations on your RP model such as light machining, assembly or incorporating last minute design changes.
