Sinterização selectiva por laser (SLS)
Custom SLS Parts: Ideal for Rapid Prototyping and End-Use Production
Advantages of SLS 3D Printing
Selective laser sintering (SLS) is a form of industrial 3D printing that can swiftly produce accurate prototypes and fully functional production components within a single day. It employs various nylon materials and a thermoplastic polyurethane (TPU), offering final products with high durability and resistance to heat and chemicals, as well as excellent flexibility and dimensional stability. SLS technology eliminates the need for support structures, which simplifies the process of stacking multiple parts in a single production cycle and makes it a cost-effective choice for larger quantities of 3D-printed items.
Typical applications of selective laser sintering include:
- Tooling and fixtures
- Enclosures
- Interlocking joints and flexible hinges

Materials for SLS 3D Printing
| Material | Caraterísticas | Aplicações |
|---|---|---|
| PA 11 Black (PA 850) | Provides ductility and flexibility without sacrificing tensile strength and temperature resistance. | Widely used general-purpose material for functional and moving parts. |
| PA 12 White (PA 650) | The strongest of the unfilled nylon materials and slightly stiffer than PA 11 Black. | General-purpose applications like functional and end-use parts. |
| PA12 Mineral-Filled (PA620-MF) | 25% mineral fiber-filled PA powder, increases stiffness and HDT (up to 363 °F). | Ideal for parts requiring stiffness and high temperature resistance. |
| PA12 40% Glass-Filled (PA614-GS) | PA powder with glass spheres, providing stiffness and dimensional stability, but lower impact and tensile strengths. | Suitable for parts that require long-term wear resistance properties. |
| Polipropileno Natural | Offers chemical resistance properties, tough and durable, yet flexible, low weight material. | Suitable for applications requiring chemical resistance, like containers. |
| TPU 70-A | White thermoplastic polyurethane combining rubber-like elasticity with good abrasion and impact resistance. | Ideal for seals, gaskets, grips, hoses, or any other dynamic resistance applications. |

The benefits of SLS 3D printing
Why Use SLS 3D Printing?
How Does SLS 3D Printing Work?
The SLS machine starts by sintering each layer of the part geometry onto a heated bed filled with nylon-based powder. After each layer is fused, a roller moves across the bed to evenly apply the next layer of powder. This process continues, building the part layer by layer, until the entire structure is complete.
Upon completion, the full powder bed containing the encased parts is transferred to a breakout station. Here, the bed is elevated, and the parts are carefully separated from the surrounding powder. Initially, a manual brushing is performed to clear away most of the loose powder. Subsequently, the parts undergo bead blasting to eliminate any remaining residual powder, before they are sent to the finishing department for the final touches.
