Selective Laser Sintering (SLS)
Robust End-Use Components
Selective Laser Sintering (SLS) is a powder-bed fusion technology that utilizes a high-powered laser to sinter (fuse) fine polymer powder particles together, layer by layer. This process creates exceptionally strong, durable, and highly complex parts with no need for dedicated support structures, as the unfused powder acts as its own support.
This is the go-to method for tough, load-bearing functional parts and cost-effective, low-to-mid volume manufacturing.
- Exceptional Durability & Strength: Produces robust, load-bearing components from engineering-grade nylon materials.
- Design Freedom: Achieve highly complex, interlocking, or internal geometries with no support removal required.
- Material Versatility: Access to nylon (PA 12, PA 11) and composite powders for specific mechanical properties.
- Rapid Lead Times & Cost-Efficient Production.
Advantages of SLS Technology
Superior Strength and Durability
SLS parts, typically made from Nylon (Polyamide), exhibit excellent mechanical properties, making them highly suitable for functional prototypes, end-use parts, and low-volume production that must withstand significant stress and impact.
No Support Structures Required
The surrounding unfused powder naturally supports the part during printing. This eliminates the need for manually designed and removed supports, reducing post-processing time and enabling the creation of highly complex internal features and interlocking parts.
Excellent Design Freedom
Since supports aren't needed, SLS offers unparalleled geometric freedom. You can design complex, organic, and intricate geometries, and even nest multiple parts within a single build volume to maximize efficiency.
High Production Throughput
The ability to tightly nest parts in the build chamber (up to 100% packing density) and print without supports leads to a higher volume of parts per build, making it a cost-effective and time-efficient option for batch manufacturing.
Material Recyclability
A significant portion of the unused polymer powder can be collected, sieved, and reused in subsequent builds, minimizing waste and making the process more sustainable and cost-effective than processes that use high volumes of non-reusable liquid resin.
Isotropic Mechanical Properties
The way the laser sinters the powder layers typically results in parts that are isotropic, meaning their mechanical properties (strength and stiffness) are consistent in all three directions ($X$, $Y$, and $Z$), which is crucial for reliable functional components.
