Selective Laser Sintering

One of the standout advantages of the SLS process is the freedom in design. Since no support material is required, even the most complex geometries, intricate structures, and interlocking assemblies can be produced without additional tools or molds. This allows for designs that are difficult or impossible to achieve using conventional methods. Prototypes and functional models can be created in a very short time—without the limitations imposed by tools and molds.

The SLS process is suitable for a wide range of materials, including robust plastics such as nylon, TPU, and glass- or carbon-fiber-reinforced polymers. These materials offer high mechanical strength, durability, and flexibility. Components produced using SLS often exhibit high stability and resistance, comparable to injection-molded plastic parts. This makes SLS ideal for functional prototypes that must withstand real-world conditions, as well as for end products that require longevity.

SLS provides a fast way to produce functional components and prototypes. The layer-by-layer technology and automatic laser sintering ensure that prototypes and small series can be produced in a short time. Companies can respond quickly to market developments and accelerate their product development. Additionally, the elimination of mold-making and tool manufacturing speeds up the process and significantly reduces upfront costs.

SLS is particularly suitable for small series and the production of customized products, as it does not require expensive tools. This makes it possible to economically produce small series and unique items, which is especially valuable for industries such as medical technology or the consumer goods market. For product development that requires quick iteration and adaptation, the SLS process provides a cost-effective solution to create and test variations without the expense of changing tools.

Thanks to the high level of detail and strength of SLS parts, engineers and designers can develop functional prototypes that can withstand real-world conditions—whether for heat tests, stress tests, or other extreme scenarios. The SLS process enables the production of robust prototypes that already meet key requirements of the final product. This ensures that design and functionality can be thoroughly tested and optimized during the development phase.

Another advantage of the SLS process is the ability to reuse unsintered powder. Since the excess powder does not fuse during production, it can be reused for subsequent print runs. This reduces material waste and makes SLS a more resource-efficient manufacturing method compared to processes that require support structures or tools. For companies with high sustainability requirements, this is a crucial advantage.
