Unlock the Power of SLS 3D Printing
Selective Laser Sintering (SLS) is a cutting-edge 3D printing technology that transforms powdered materials—typically nylon—into high-performance parts with unmatched precision. Using a high-powered laser, SLS fuses layers of fine plastic powder, building intricate and durable components directly from digital designs.
The process starts with a thin layer of powder evenly spread across a build platform. A laser then selectively melts and bonds the material according to the object’s cross-section. Once a layer is complete, the platform lowers, and the next layer is fused—repeating this process until the final product is fully formed.
SLS printing offers exceptional advantages, including the ability to create highly complex geometries, rapid prototyping, and the production of strong, lightweight parts. Widely used in aerospace, automotive, medical, and engineering industries, SLS is the go-to solution for manufacturing durable components with intricate designs and high-performance material properties.
Harness the power of SLS 3D printing to push the boundaries of innovation.
Features
-
The original revival technology of PA powder makes the powder
utilization rate close to 100%, ensuring the high surface quality
and great mechanical properties of the parts. -
Through the optimization of the anti-oxidation of consumables,
after the printing is completed, the cylinder can be taken to cool
down, and at the same time, the printing operation of the next
cylinder can be continued when the equipment is still at a high
temperature, which can effectively reduce the cooling and warm-up
time and reduce energy consumption. -
Adopts an external powder cylinder to realize automatic powder
feeding and powder replenishment at any time during printing. -
The scraper can be easily adjusted in multiple axes. Two-way
powder supply and powder spreading with double scrapers even
the powder spreading, improves the stability of the temperature
field and reduce the amount of powder spilled.
Ideal Applications
SLM printers can create models that are impossible to manufacture with standard manufacturing techniques. Models can be hollow or built with internal channels and components integrated into the design. SLM printing is commonly used in aerospace for reducing part counts and increasing reliability by creating a single part with coolant channels ducting and electrical components all integrated into one part.

Functional Prototyping
Selective Laser Sintering (SLS) is highly advantageous for both functional prototyping and the fabrication of complex geometries. In functional prototyping, SLS offers the ability to create parts with high strength and durability, making it ideal for testing prototypes that need to withstand mechanical stress or have specific material properties. This is particularly valuable in industries such as aerospace and automotive, where functional testing is critical. Simultaneously, SLS excels in producing complex geometries with intricate internal structures. Its layer-by-layer additive manufacturing process enables the creation of parts with intricate details, such as lattice structures or nested components, without the need for support structures. This capability unlocks new design possibilities and allows for the fabrication of parts that would be challenging or impossible to produce with traditional manufacturing methods. Therefore, SLS is a preferred choice for applications that demand both functional performance and complex geometries, offering versatility and efficiency in the production of innovative components.

Batch Production with SLS: Efficiency, Flexibility, and Cost Savings
Cost-Effective Manufacturing
SLS 3D printing is a highly economical solution for batch production, offering significant cost savings over traditional methods like injection molding. With the ability to print multiple parts in a single build cycle, manufacturers can produce hundreds of components efficiently without the high costs associated with mass production.
No Tooling, No Limits
Unlike conventional manufacturing, SLS eliminates the need for expensive molds or tooling. This removes the upfront investment required for traditional methods, making it an ideal choice for small-batch production where tooling costs may not be justified.
Unmatched Design Freedom
SLS allows for the creation of intricate and highly complex geometries without additional tooling or assembly. Each part within a batch can be customized or optimized for its intended function, enabling truly tailored manufacturing solutions.
Faster Turnaround, Faster Innovation
With SLS, production cycles are significantly shorter compared to traditional manufacturing. Once a 3D model is finalized, multiple parts can be printed simultaneously in a single build, reducing lead times and enabling rapid prototyping, iteration, and final production.
Unlock the power of SLS batch production and bring your designs to life with speed, precision, and cost efficiency.
