Vapor Smooth SLS 3D Printed Parts
Elimold can vapor smooth 3D printed parts to achieve a superior surface finish. Vapor smoothing is a batch automated smoothing process that produces a high-quality surface. Combined with the low-cost SLS technology, this surface finish can make parts comparable to injection molding in form and function. Vapor smoothing creates a uniform, sealed surface with a semi-gloss appearance. SLS parts can be dyed. The enhanced surface also improves the overall performance of the 3D printed part, including ultimate tensile strength, flexural yield strength, and elongation at break. Vapor smoothing can be applied to HP Multi Jet Fusion, Selective Laser Sintering, and Fused Deposition Modeling parts, and is suitable for both hard plastics and elastomers.
Applications of SLS 3D Printing
SLS uses production-grade nylon materials to create parts that are as strong, functional, and durable as those made using traditional manufacturing techniques. The durability of SLS makes it an ideal technology for the following applications:

How does SLS 3D printing work?
Selective Laser Sintering (SLS) is an industrial 3D printing process that produces accurate prototypes and functional production parts in as little as 1 day. A wide range of nylon-based materials are available, which can produce highly durable final parts. The laser selectively melts a thin layer of plastic powder. The part is built layer by layer in a powder bed. The laser sintering machine applies a layer of plastic powder to the build platform and then melts the powder with a laser (or multiple lasers). The build platform is then lowered and the next layer of plastic powder is laid on top of it. By repeating the process of laying down powder and melting where needed, the part is built in the powder bed. Once the build is complete, the entire powder bed, along with the encapsulated part, is moved to a disassembly station where it is lifted and the part is removed from the powder bed. First, it is manually brushed to remove most of the loose powder. The part is then sandblasted to remove any remaining powder and sent to the finishing department.
Can SLS 3D Printing Create Metal Parts?
Standard SLS printing is not designed for metal. However, metal 3D printing processes such as DMLS (direct metal laser sintering) and SLM (selective laser melting) are based on similar principles. They use a similar powder bed fusion method, but operate at higher temperatures and use different types of lasers. So, while SLS printers cannot print metals natively, the powder bed fusion technology family definitely includes systems that are compatible with metals.

Online Selective Laser Sintering 3D Printing Service
We provide high-quality online Selective Laser Sintering 3D Printing services. Selective Laser Sintering (SLS) is one of the most popular 3D printing technologies, capable of producing high-precision and durable parts, ideal for end-user, small and medium-volume production or rapid prototyping. A wide selection of printing materials and fast delivery times are our strengths. In addition, SLS is an ideal technology for many rapid prototyping or rapid tooling applications. Since SLS has a much higher throughput and speed than some other additive manufacturing technologies, it can quickly prototype and test new customized parts or components. The advantage of SLS is that it can print high-durability final parts that require heat resistance, chemical resistance, flexibility or dimensional stability. In addition, SLS 3D printing does not require support structures, so multiple parts can be easily nested in one model, and since there is no need to remove support structures, there is less risk of damage to the complex internal geometries that 3D manufacturing can produce.

Differences between SLA and SLS 3D Printing
While both SLA and SLS are considered high-precision 3D printing technologies, they differ significantly in terms of materials, applications, and operational requirements. SLA (stereolithography) uses a light source to solidify liquid resin into smooth, detailed parts, ideal for visual prototypes, dental models, and complex designs. SLS (selective laser sintering) uses powdered thermoplastics to produce strong, durable, mechanically excellent, functional parts without the need for support structures. SLA is best suited for aesthetic, small-scale applications, while SLS excels in industrial-grade, performance-driven use cases where strength and durability are critical.
The Difference Between SLS 3D Printing and SLM 3D Printing
Selective Laser Melting (SLM), sometimes referred to as Direct Metal Laser Melting (DMLM), uses a laser to melt metallic powders in successive layers. The machine fully melts the powder before another bed of powder is added above the melted layer. SLM causes the metal granules to melt together to fully form one homogeneous piece. The primary difference between SLA and SLS is the material used for each process. SLS can be applied to plastics, glass and ceramics, whereas SLM is used exclusively for metal alloys.
Differences between SLS 3D printing and FDM 3D printing
FDM extruders extrude heated filament through a nozzle. The extruder is mounted on a gantry system, so it is very similar to a hot glue gun. The movement rate and speed of the nozzle is limited by the extrusion rate of the heated filament. SLS is not limited by this because the material is not extruded, but melted by a laser moving along a raster path at speeds of up to 5000 meters per second. This makes SLS an extremely fast and precise 3D printing method. With SLS printing, production time can be greatly reduced due to the high speed of the laser. It takes about 20 parts before the production time doubles. Generally, SLS printing speeds are 8 times faster than FDM printers on average, and even 20 times faster in some cases. SLS is a high-throughput, high-productivity form of 3D printing.
SLS 3D Printing vs. Plastic Injection Molding
SLS 3D printing excels when you need durable plastic parts. SLS parts are known for their toughness and durability, and their performance is comparable to parts produced by traditional manufacturing methods such as injection molding. In addition, when plastic parts need to be produced in small batches, we often encounter the question of which manufacturing process is the most cost-effective. If you are not sure whether SLS 3D printing or plastic injection molding is the best process for your component or assembly, we are happy to provide you with a comparative quote. If you need plastic parts made of injection molded materials or need a large number of parts, we recommend the rapid processing process of injection molding for the production of prototypes and small batches. When plastic parts need to be produced in large quantities, plastic injection molding is more cost-effective than SLS 3D printing.
One-Stop SLS 3D Printing Manufacturing Service
Selective Laser Sintering technology is not just for prototyping. It can also be used to produce low-volume production parts, which is ideal if you are waiting for injection molds to be manufactured. SLS works with thermoplastics. This means it can be used to quickly create functional prototypes of new product designs. Once the part design is complete, you can move to injection molding for production. With our cross-functional engineering expertise, we can help you adapt your part design to work well in both production environments. SLS can be used to build workholding devices to hold metal parts for CNC machining. Because SLS can achieve a large build volume, precision of small features, and high mechanical strength, it is ideal for large jigs and fixtures. If tight tolerances are required, 3D printing technology can be used to add additional material to critical surfaces. Then, it can be machined to the required tolerances.
