The Different SLS 3D Printers on the Market

Once an exclusive tool for high-budget labs, selective laser sintering (SLS) has become a practical solution for modern manufacturing. The technology uses a laser to fuse plastic powder layer-by-layer, and historically, it was sidelined by high costs and operational complexity. However, breakthroughs in desktop solutions have made the process more accessible, and the library of compatible materials has grown to include high-performance composites, recycled polymers, and flexible TPUs. Today, SLS is widely used by the automotive, consumer goods, aerospace and medical industries.

Below, we examine the desktop and industrial SLS 3D printers currently on the market. Whether you’re looking for a more user-friendly, desktop option, or a high-volume industrial system, this guide (with machines listed in alphabetical order by manufacturer) explores the solutions defining the SLS landscape.

Industrial SLS Solutions

3D Systems’ SLS Solutions

3D Systems, a well-known name in the additive manufacturing industry, offers two SLS printers: the SLS 300 and the SLS 380. The former, with a build volume of 300 x 300 x 300 mm, is designed for space-constrained environments such as offices, laboratories, or small workshops, as it only occupies 0.45 m² of floor space. It uses a standard power outlet, generates minimal noise, and does not require a cooler or fume extractor. According to 3D Systems, it can be operated by non-specialized personnel. The powder is loaded using cartridges, which avoids direct material handling and eliminates the need for dedicated infrastructure. In exchange for this simplicity, material compatibility is limited to PA11 and PA12.

The second, the SLS 380, is larger, with a build volume of 381 x 330 x 460 mm, and works with seven materials, including PA11, PA12, medical-grade plastics, and flame-retardant materials. The machine also features several interesting functions, such as automated nesting of 3D printed parts.
