Powder 3D Printing SLS on 3D printers

SLS 3D printing: capabilities and features
SLS (Selective Laser Sintering) is one of the most advanced technologies additive manufacturingthat uses laser sintering of polymer powder to create finished products. Thanks to this process, it is possible to produce strong, heat-resistant and chemically resistant parts without the need for mechanical modification.
How is SLS 3D printing different from other methods?
✔ Lack of support – the powder independently holds the model, allowing you to print complex shapes
✔ High accuracy – admission to 0.1 mm, which ensures a perfect match to the digital model
✔ Load resistance – products from Nylon 12 (PA12) stronger than ABS and photopolymers
✔ Resistance to moisture and chemicals – suitable for functional parts, housings and industrial mechanisms
SLS printing is actively used in medicine, mechanical engineering, defense industry and electronics, and also allows you to create functional prototypes and final products.

Material used for SLS 3D printing
Nylon 12 (PA12) – is a strong, wear-resistant and chemically resistant thermoplastic that outperforms ABS plastic and photopolymers. It does not yellow in the sun, is resistant to oils, solvents, is non-flammable and biocompatible, and its IP67 protection class makes it waterproof and dustproof.
Thanks to these properties Nylon 12 (PA12) is widely used in 3D printing to create prototypes and finished products in industry and medicine. It is used to produce housings, fasteners and strong parts that can withstand high loads.
Strength and durability
PA12 has high level of strength, which allows it to be used in engineering designs, industrial products and functional prototypes.
Chemical and thermal resistance
The material withstands high temperatures up to +170°C yes there is resistant to oils, acids and alkalis, making it ideal for industrial use.
Moisture resistant and IP67
Thanks to low water absorption, parts made of PA12 can meet the standard IP67 – complete protection against dust and immersion in water.
Detailing and stronger than ABS
Unlike ABS, PA12 stronger, less brittle and has better mechanical properties, which allows you to create durable and flexible components.
High physical characteristics
Nylon 12 (PA12) creates strong, gray-surfaced parts with high abrasion resistance. Thanks to the dense sintering, the layers do not crack, and the products retain their strength even under temperature changes and ultraviolet exposure.

Resistant to water and chemicals
Products from Nylon 12 (PA12) remain strong even with prolonged contact with chemicals. The material retains its properties in interaction with water, oils, solvents, gasoline and alkaline environments.
Due to its minimal porosity, polyamide does not require impregnation with epoxy resins for water resistance. It is used to make hermetic vessels and pipelines that can withstand pressures up to 20 atmospheres. Denser than water, it absorbs no more than 5% of its own weight even after a day of immersion.
