PA11 Deep GB - SLS Printing Powder

PA11 Deep GB is a high-performance powder composed of polyamide 11 and glass microspheres developed by Fabulous Materials for SLS 3D printing. This fine powder, with a median particle size of 45-60 µm, is designed to produce detailed models and functional parts with high durability and excellent chemical resistance. It is the perfect material for the aerospace sector, the military industry, automotive racing applications, outdoor use, and unmanned aerial vehicle (UAV) components.

This material exhibits excellent chemical resistance to aggressive substances, such as oils, hydrocarbons, solvents, gasoline, and alkaline products. It also has very good resistance to corrosion and abrasion. Thanks to the powder's intense black color, the parts do not need to be dyed after printing, simplifying the production process. The powder is biologically sourced and sustainable, meeting current environmental standards. Additionally, PA11 Deep GB can be submerged in potable water and used in food contact applications.

Mechanical properties

In terms of mechanical properties, PA11 Deep GB stands out with high values in both the Young's modulus and flexural modulus: 2900 MPa and 2400 MPa, respectively. These parameters make PA11 Deep GB powder much stronger than PA11 Dark powder. The tensile strength, however, is the same as PA11 Dark powder: 45 MPa in the XY direction and 40 MPa in Z. The elongation at break of PA11 Deep GB powder is between 4-6% in the XY axes and 4% in the Z axis.

This PA11 Deep GB powder is characterized by being strong and versatile, with a Shore hardness of 80 D and a melting point of approximately 196-204°C, making it ideal for demanding applications in harsh environments. When printing with this powder, it is important to note that it has a moderate moisture absorption of around 0.85% over 24 hours at 23°C.

3D printer compatibility

PA11 Deep GB powder is compatible with all powder-based 3D printing systems, including compact and desktop SLS 3D printers, meaning it offers wide accessibility for various production scales. The powder is available in two formulations: one optimized for industrial equipment from major manufacturers like EOS, Farsoon, and 3DSystems, and another designed for desktop SLS printers like Sinterit and Sintratec. For excellent results, it is important to use open parameters when printing with this material. If in doubt, it is recommended to consult the manufacturer or equipment supplier to ensure the correct settings are applied.
