SLS (Selective Laser Sintering)


Selective Laser Sintering (SLS) is an advanced additive manufacturing technique revolutionizing the production of intricate three-dimensional objects. Our SLS 3D printing service harnesses the power of high-powered lasers to selectively fuse powdered materials, layer by layer, bringing your designs to life with unparalleled precision and efficiency.

Process Flow:


Our process begins with your digital design files, meticulously prepared using state-of-the-art Computer-Aided Design (CAD) software. These files are then sliced into thin layers, generating precise cross-sectional data that guides the printing process.

Material Handling:

We load your chosen powdered material—be it polymer or metal—into our cutting-edge SLS 3D printers' build chambers. The powder is evenly distributed across the build platform, forming a fine layer ready for printing.

Laser Sintering:

Next, our high-powered lasers precisely scan the cross-sectional data onto the powdered material, strategically melting and fusing particles together. This controlled fusion process solidifies the material, incrementally building your object layer by layer with remarkable detail.

Layer-by-Layer Building:

As each layer is sintered, the build platform descends, and a fresh layer of powder is evenly spread atop the previous one. This iterative process continues until your entire object is meticulously formed, ensuring structural integrity and dimensional accuracy.

Cooling and Post-Processing

Upon completion, your printed object undergoes a cooling phase within the printer. Following this, any excess powder is meticulously removed, either manually or through specialized equipment. Depending on your specifications, additional post-processing treatments such as polishing, dyeing, or surface finishing may be applied to enhance the final product.


Design Freedom:

SLS 3D Printing technology enables the creation of highly complex geometries, including intricate internal structures and moving parts, without the need for assembly or additional tooling.

Versatility of Materials:

SLS 3D Printing can work with a wide range of materials, including polymers, metals, ceramics, and composites, allowing for the production of parts with diverse properties.


As SLS does not require moulds or tooling, it eliminates the need for expensive and time-consuming manufacturing setups. This reduces production costs, especially for small batch sizes or customized products.

Time Savings:

SLS 3D Printing technology allows for rapid prototyping and quick iterations during the design process, accelerating product development cycles and reducing time-to-market.
