PA12 + GF15 is another material offered by Fiberlogy, which is a derivative of Nylon PA12. It was created by reinforcing it with glass fiber (GF), which constitutes 15% of the product. This made it possible to significantly increase the durability, stiffness, and thermal and chemical resistance compared to pure Nylon. PA12 + GF15 has a stiffness of 3.6 GPa and a temperature resistance of up to 170°C.

Unlike Nylon with an addition of carbon fiber, available as Fiberlogy PA12 + CF5 and PA12 + CF15, this filament offers greater flexibility, making it ideal for applications operating under variable loads and exposed to impacts.

The very low shrinkage ensures high dimensional stability. This combined with high durability makes engineering excellence achievable at home. This filament does not require a heated chamber. However, due to the high abrasiveness, steel or ruby nozzles should be used for printing in order to prevent excessive wear.

AUTOMOTIVE: elements in the engine compartment, housing of vehicle components, air intakes, fluid fillers
INDUSTRY: spare parts, short series, utility models
MEDICINE: prostheses, medical equipment
SPORT: accessories, pads, airsoft elements

Notes The material has highly abrasive properties. We recommend the use of hardened steel or ruby nozzles.
Wear gloves (the possibility of micro damages on the skin). Use a dust mask and protective glasses when processing.


Print Surface Material Properties Bed Temp Adhesives / Release Agents
Glass / Borosilicate Glass Poor adhesion 90°C – 110°C Magigoo PA needed
Ceramic Glass Poor adhesion 90°C – 110°C Magigoo PA needed
Textured PEI Glass Good adhesion 90°C – 110°C Magigoo PA needed
Smooth PEI Spring Steel Sheet Poor adhesion 90°C – 110°C Magigoo PA needed
Textured PEI Spring Steel Sheet Good adhesion 90°C – 110°C Magigoo PA needed


Nylon PA12 is very hygroscopic. it must be stored in an airtight container and ideally dried before printing. an enclosed print chamber is highly recommended.
