DETECT PA11 is a polyamide 11-based composite powder formulated by Fabulous for powder bed laser sintering systems (SLS, LS). Its navy blue bulk colouring, combined with specific fillers, makes the produced parts detectable by optical, magnetic and X-ray methods, and allows them to be magnetised.
The formulation incorporates bio-based components and retains the high mechanical properties expected of sintered PA11, with a Young's modulus above 1600 MPa and an elongation at break of around 12.5 % in the XY plane.
Processing
Melting occurs between 190 and 202 °C (DSC measurement), with a typical process temperature of around 183 °C depending on the machine and measurement method used. Laser particle size distribution is 45–65 µm, with a tapped bulk density of approximately 0.65 g/cm³ and a sintered part density close to 1.13 g/cm³.
A refresh rate of 50 % is recommended to preserve process consistency from one cycle to the next. Wall airtightness is achieved from 2 mm thickness. In post-processing, blasting gives a roughness Ra of 12 ±4 µm, reduced to 6 ±2 µm after finishing.
Compliance and applications
DETECT PA11 meets European Regulation No. 10/2011 and FDA CFR 21 for food contact, and complies with Good Manufacturing Practice (GMP). Its PA11 matrix offers good chemical resistance to alkaline media, hydrocarbons, oils, fuels and common solvents; it is however sensitive to acids. Produced parts are aimed at the food, pharmaceutical and medical sectors, packaging and safety equipment, where detection of accidental fragments by metal, optical or X-ray inspection is required on the line.
