Explore metal sintering, ABS, and SLM 3D printing technologies for your projects.

 
Selective Laser Sintering (SLS) is currently the most commonly used powder bed fusion 3D printing system. It is an additive manufacturing (AM) technology that creates objects by building (printing) layer by layer. Based on a 3D computer drawing, a high-powered laser manufactures parts layer by layer on a preheated powder bed. The laser melts the powder particles, and the powder bed supports the product during manufacturing, eliminating the need for internal product structure support.

During the SLS process, the powder bed is equipped with a roller system that evenly distributes a thin layer of powder before sintering. The finished product must cool, and any loose powder must be removed in a post-printing cleaning process. Any remaining unsintered powder can be used in the next production run, making SLS a zero-waste technology.

SLS is ideal for rapid prototyping, small-batch production, and custom manufacturing, especially excelling in complex geometries, including thin walls, cutouts, reverse dimensions, tapered shapes, and other complex design features.

Metal SLS 3D printing is a widely used additive manufacturing process that offers exceptional precision and the ability to print complex geometries while providing mechanical properties similar to injection-molded parts. This process is ideal for functional prototyping and small-batch production.

SLS-printed parts can be made from a variety of materials, including nylon, polymers, ceramics, and metals. While these printed parts are similar in strength to standard metal parts, they are much lighter. SLS printing systems are often associated with plastic-based materials such as carbon fiber nylon and aluminum nylon, which are also lightweight, high-performance materials.

These materials not only offer greater strength but also exhibit a metallic appearance while maintaining a lighter weight. Nylon, along with carbon fiber and aluminum, is often used as an alternative to metal parts for a variety of applications, including jigs, fixtures, tools, and functional prototyping.

Furthermore, SLS printers can also print aluminum and stainless steel alloys through a derivative process called Direct Metal Laser Sintering (DMLS). This process is also known as Selective Laser Melting (SLM), although the printing process is the same, a different material is used.
