Printers 100-500 thousand PLN – SLS

What is SLS technology?

SLS is one of the most advanced methods of 3D printing. The process involves sintering a powdered polymer (e.g., polyamide) with a precise laser beam, layer by layer. The un-sintered powder in the working chamber provides a natural support for the model being created, eliminating the need to generate additional supports. This makes SLS technology ideal for engineers, designers and manufacturers who need functional prototypes, production tools or finished parts with complex designs.

Advantages and applications of SLS 3D printers

SLS 3D printers offer benefits that put them at the forefront of professional incremental manufacturing technologies.

Key benefits:

• Complete geometric freedom: the absence of supports allows complex shapes, internal channels and moving mechanisms to be printed in a single process;
• Exceptional durability: prints from materials such as PA12 or PA11 have excellent mechanical properties, similar to injection molded parts;
• Production efficiency: the ability to stack multiple models throughout the work chamber maximizes efficiency and allows for short-run production.

Main applications:

• Automotive – creating functional prototypes, spare parts and vehicle components,
• Aerospace – manufacturing lightweight yet robust components that must meet rigorous standards,
• Medical – manufacturing personalized implants, anatomical models and surgical instruments,
• Electronics – manufacturing of complex shaped enclosures and insulating components.

SLS 3D printing materials

The flexibility of SLS technology is based on the wide range of materials available. Among the most popular are:

• PA12 (Polyamide 12). The most versatile material, valued for its high mechanical strength, dimensional stability and chemical resistance.
• PA11 (Polyamide 11). It offers greater flexibility and impact resistance compared to PA12, making it ideal for the manufacture of components subjected to dynamic loads.
• Flexible materials (TPU/TPE). Enable the printing of flexible, rubber-like parts such as gaskets, shock absorbers and shoe prototypes.
