How does Selective Laser Sintering (SLS) work?
SLS uses lasers for melting nylon powder into plastic. SLS allows for precise and minimal waste in the creation of complex shapes. This method is a cost-effective way to produce intricate plastic parts, which were previously impossible. SLS 3D printing is used in medical applications and for other specialized uses.SLS is capable of creating intricate shapes and complex details. SLS is also capable of producing strong parts that have tight tolerances. This type of 3D printer can produce rough prototypes of your products as well as large quantities of prototypes in plastic. SLS is a viable option for 3D-printing and an excellent choice for prototyping.
Using EPRO’s Selective Laser Sintering (SLS) has many advantages
Complex Geometries
SLS allows for the creation of parts with fine detail by layering intricate designs. SLS is ideal for prototyping as well as end-use manufacturing.
Bulk Produce Parts Rapidly
Multi-part constructions are possible. SLS scans the laser quickly and efficiently, leading to high productivity at low cost. It increases production and lowers costs.
Low Cost Parts
SLS does not require any post-processing or support structures. SLS is low-cost per part because leftover powder is reused and support structures are eliminated.
Flexible design
SLS allows for the fabrication of complex geometries and moving parts as well as interior components, without any support structures.Flexible design leads to more innovative and creative products.
Mechanical properties of exceptional quality
SLS produces isotropic components with strong bonds. SLS is a great manufacturing method because of its high impact resistance.
Colorblindness
SLS parts are dyeable and colorable. By adding pigments to the raw material powder, SLS printing is able to dye or color parts. Colors can be customized and vibrant.

SLS has the following advantages over SLA:
Material properties
- SLS 3D printing can be done with plastic, metal, ceramic, and glass powders. Materials made with SLS have high mechanical strength, high heat resistance, and good chemical stability. SLA 3D printers can only print liquid photopolymers, which perform poorly.
Surface finish
- The SLS method produces loose, rough prototypes, while the SLA method produces smooth, detailed surfaces. The loose surface finish of SLS can still be enhanced with various post-processing techniques. SLS-printed objects can be polished, sanded, and coated to improve their appearance.
Glue bonding strength
- The porous surface of SLS prints makes the adhesive penetrate deeper and create a stronger bond between layers than SLA 3D printing.
Environmental resistance
- Temperature, humidity, chemical corrosion are not a problem with SLS 3D printed prototypes. Hence, SLS 3D printed prototypes are suitable for applications where multiple environmental factors are expected, such as automotive parts. Moisture and chemical attack make 3D printed SLA prototypes prone to becoming soft and deformed above 38°C.
Machining performance
- SLS can be milled, drilled, and tapped easily during processing. The thermoplastic materials used in SLS machining are extremely strong and durable. While SLA 3D printing should be handled carefully to avoid damage to the parts.

SLS (Selective laser Sintering) Tips
SLS is a versatile tool for both production and prototypes.
SLS is a powder-based process, which means it produces a rougher surface finish. It also has lower resolution. Avoid large flat surfaces as they are more prone to warping. Ribs should be used to support SLS parts with flat surfaces. The ribs should be evenly spaced and perpendicular with the flat surface. The ribs must be thick enough to support the part and make it cost-effective for printing.
