Fiber Three is a German 3D printing material manufacturer specializing in technical polyamide (also known as nylon or PA) filament production. Their product range includes the LITE Family of standard materials and the PRO Family that includes professional 3D printing materials for FDM printers.
Fiber Three PA-GF 30 Pro belongs to the PA6 PRO family. It is made of 70 % of polyamide and 30 % glass fiber (ca. 150 μm).
Nylon (PA) is a low cost, highly versatile material extensively used in 3D printing due to its properties of durability, flexibility, thermoplasticity, and resistance to abrasion, friction, corrosion and chemicals. Nylon originated in 1935 and it was first used to make a toothbrush. It soon became famous as the ingredient of women’s stockings and now it is used in the automotive industry, medicine and sports. In 3D printing, it can be found in the form of powder (SLS and MJF), pellets, and filament (FDM).
When it comes to filaments, PA’s most common form is the PA6 (6 for the number of carbon atoms it contains). Nylon is a great alternative to ABS in prototyping due to its greater flexibility, durability and resistance to chemicals. It makes nylon ideal for functional parts, connectors and hinges and even medical prosthetics, where functional flexibility, lifespan and resistance are desired. Nylon is also an interesting substitute for PC in some applications, as it is easier to print.
Very often nylon filaments are reinforced with the addition of carbon or glass fibers to improve the properties of the filament. Adding glass fiber increases the filament’s strength, stiffness and dimensional stability. PA with glass fibers is more ductile than PA with carbon fibers.
Two important things to have in mind when printing with PA is that:
This particular PA GF 30 Pro filament is characterized by great tensile strength with remaining impact resistance, higher compression strength than F3 PA-GF Pro, and excellent heat resistance. Pieces printed with 3F PA GF 30 Pro can be safely sterilized without being compromised (autoclave cycle up to 180°C), which makes this filament apt for medical purposes as medical equipment. This filament is not electrically conductive and can be used as an alternative for carbon fibers.

Due to the fact that this filament contains glass fibers, it is highly recommended to use wear-resistant nozzles (of at least 0.25 mm in diameter), such as hardened steel nozzles, the Olsson Ruby Nozzle, the Vanadium nozzle or the Tungsten carbide nozzle. Using a regular nozzle with abrasive filaments, such as those enriched with carbon fiber and glass fiber, will erode the nozzle’s shape and influence the quality of future prints. The pieces may come out blobby and stringing may occur due to the changed diameter or even shape of the nozzle (due to abrasion).
Another factor to have in mind is that the F3 PA GF 30 Pro filament is characterized by greater stiffness, so it is recommended to avoid sharp curves on the path from the spool to the printer’s extrusion system.
PA (nylon) filaments are highly hygroscopic. They have to be kept dry to ensure their satisfying performance. Humidity significantly reduces filament longevity. Printing with humid filament can cause many technical complications (extruder jams, poor adhesion of the piece to the bed, delayed or continuing filament extrusion, bubbles and steam coming out of the extruder) and poor quality of the printed piece (holes in the top parts, inconsistency in repeated builds, soft and fragile pieces). To avoid those problems, PA filament should be stored in a drying case during, before and after the printing process.
This 3F PA GF 30 Pro adheres well to epoxy based fiber plates or the dedicated Fiber Three ProPrint printing surfaces, which makes it a versatile and adaptable product.
This filament was tested on multiple 3D printers and various slicing softwares (Cura, Simplify3D, Prusa Slicer, ideaMaker). The detailed profiles and results can be consulted on the manufacturer’s website.
