Selective Laser Sintering (SLS) is an additive manufacturing method utilizing a laser to selectively fuse powdered materials, enabling the creation of intricate parts unfeasible through traditional methods. Recent advancements in materials and process control have extended SLS beyond prototyping to viable production applications. Downloading the design guide provides insight into design considerations tailored for SLS fabrication.
SLS stands as the ultimate solution for a myriad of applications, including:
Selective Laser Sintering (SLS) is a 3D printing process that uses a bed of thermoplastic powder and a laser to create prototypes and functional end-use parts for a wide variety of applications. SLS creates tough and geometrically complex components for batch or serial manufacturing in a wide variety of applications from serialized aerospace production parts to prototypes in consumer applications. SLS provides parts that are strong, heat resistant, and repeatable. SLS was one of the earliest 3D printing processes to be adopted into end-use part production, taking to the skies through aerospace ducting production parts.
SLS builds robust parts with a wide range of filled nylon materials, making it an ideal process for applications such as duct work, fuel tanks, and brackets, as well as functional prototyping. SLS doesn't require labor to remove support structures as a simple shake of the part will remove the unused thermoplastic powder, enabling true zero-cost complexities in design.
SLS (Monikers: Powder bed fusion, LS, plastic laser sintering) builds with a CO₂ laser that melts cross-sections of a CAD design in powdered material.
The CAD model is oriented in space alongside copies of itself or other geometries. The software will then create thousands of layers that make up the 3D objects contained within the build chamber. These layers contain information to tell the equipment where the laser needs to melt material.
Laser sintering begins by heating its internal build chamber to just below the melting point of the powdered plastic. There is a large chamber of thermoplastic powder, which a recoater blade moves across the top surface to create a very flat surface. A CO₂ laser traces areas of the specified layer where there needed. Once the layer has been melted, the z-stage of the machine will drop slightly allowing the recoater blade to add a very thin layer of material on top of the previously melted layer. Then the laser will trace the areas it needs to melt on this layer, and the process is repeated 100's to thousands of times to create a 3D object.
Once the parts are done building, the powder and the parts need to cool. Once they are ready to be removed, printed parts simply need a little shake or shot with an air hose to remove the support. Much of the support (powder) can be recycled for use in future builds.
Our quality systems ensure consistent handling and recycling of materials along with machine maintenance and process control limits. This provides material traceability, mechanical property verification, dimensional and other performance criteria checks to ensure the parts we deliver meet customer specifications repeatedly.
