Fiberlogy Filament
Polish engineering-focused manufacturer known for Easy PET-G and industrial-grade PCTG. Tight +/-0.02mm diameter tolerance. -- products tracked with live pricing.
Last updated: March 2026
Fiberlogy is a Polish filament manufacturer positioned between budget brands like eSUN and premium brands like Prusament. They are engineering-focused, with their strongest products being Easy PET-G (widely praised as one of the easiest PETG filaments to print) and PCTG (a genuine engineering differentiator with 90 kJ/m2 impact strength). Their catalog covers PLA through industrial PA-CF composites, with EU distribution primarily through 3DJake.
The "Easy" prefix on their PLA and PET-G lines indicates formulations optimized for trouble-free printing with default slicer profiles. Their engineering materials (PCTG, PP, PA-CF) are where they genuinely stand out from competitors. Decorative finishes like silk are available but limited compared to brands that specialize in that area.
Fiberlogy is a mid-to-premium Polish manufacturer positioned between eSUN and Prusament. Their Easy PET-G is considered one of the easiest PETG filaments to print by reviewers with 10+ years of experience. The PCTG line (90 kJ/m2 impact strength) is a genuine engineering differentiator with no budget equivalent. PLA is competent but overpriced versus AzureFilm. The 850g net weight on 1kg-labelled spools (300g spool) is a recurring community complaint. Engineering materials are their strength - decorative finishes are not.
Product Lines
Fiberlogy's entry-level filament, designed for trouble-free printing with default slicer profiles. The "Easy" branding reflects a formulation that prints reliably without temperature tuning or special preparation. Available in a reasonable color range with consistent diameter tolerance.
Easy PLA is a competent everyday filament for prototypes, models, and functional prints that don't need heat resistance. It does what it says on the tin without surprises.
Fiberlogy's flagship product and the filament they're best known for. Easy PET-G is formulated to eliminate the stringing, oozing, and bed adhesion issues that make standard PETG frustrating for many users. The result is a PETG that prints almost as easily as PLA while retaining PETG's superior heat resistance, flexibility, and chemical resistance.
If you buy one Fiberlogy product, the community consensus is clear: make it this one. PETG is inherently more useful than PLA for functional parts, and Fiberlogy has made it genuinely easy to print.
Fiberlogy's genuine engineering differentiator. PCTG (polycyclohexylene dimethylene terephthalate glycol) delivers 90 kJ/m2 Izod impact strength - compared to 5-8 kJ/m2 for standard PETG. The "Pure Transparent" variant is FDA and EU food-contact certified, making it one of the few truly food-safe transparent filaments on the market.
Available with carbon fiber (CF) and glass fiber (GF) composites for applications requiring even higher stiffness. No real budget equivalent exists for PCTG - this is a material where Fiberlogy has carved out a genuine niche that competitors haven't matched at this price point.
Fiberlogy offers two ABS variants. Standard ABS is their full-strength formulation, printing at 260C (hotter than most competitors). Easy ABS is an ABS+ variant with modified chemistry for easier printing - reduced warping and less sensitivity to drafts, but mechanically weaker than standard ABS.
The Voron community (open-source enclosed printer builders) is positive on Fiberlogy's regular ABS, citing good consistency and nice color options. The higher print temperature is a trade-off for better layer adhesion.
Fiberlogy's UV-stable engineering filament for outdoor applications. ASA provides similar mechanical properties to ABS but with significantly better UV and weather resistance, making it the go-to material for parts that will live outside permanently.
Fiberlogy's ASA works well for its intended purpose but is priced at a significant premium over budget alternatives like AzureFilm ASA. If you're already buying from 3DJake and want convenience, it's a solid option. If price is the primary concern, look elsewhere.
A rare material offering that sets Fiberlogy apart from most competitors. Polypropylene is inherently chemical-resistant, fatigue-resistant, and FDA food-safe, but notoriously difficult to print due to extreme warping and poor bed adhesion. Fiberlogy is one of the few brands making printable PP filament.
PP is a niche material, but when you need chemical resistance (lab equipment, chemical containers, living hinges), there is no substitute. Fiberlogy's PP formulation is one of the more printable versions available, though it still requires a PP build plate or adhesion sheet.
Fiberlogy's flexible filament line, available in 30D and 40D shore hardness options. The 30D variant is softer and more elastic (similar to a rubber band), while 40D is firmer and more suitable for structural flexible parts like hinges and bumpers. Both are marketed under the "FiberFlex" brand name.
TPU is notoriously difficult to print on Bowden-tube printers, but Fiberlogy's formulation has earned praise for being more manageable than most. Prusa forum users report it "prints just like PLA" - which is high praise for any TPU filament.
Fiberlogy's professional-grade nylon offering. PA12 with 15% carbon fiber reinforcement targets users who need maximum strength, stiffness, and heat resistance. This is industrial-grade material priced accordingly, competing with brands like Polymaker and Bambu Lab in the professional segment.
Nylon composites require a fully enclosed printer, all-metal hotend, dry box during printing, and hardened steel nozzle (for the CF variant). This is not hobbyist-friendly material - it's for users who have the equipment and know why they need nylon.
Fiberlogy's metallic sheen filament for decorative prints. FiberSilk produces a smooth, reflective surface that hides layer lines effectively. Available in a limited color range compared to dedicated decorative brands - this is not Fiberlogy's focus area.
Silk filaments in general are more problematic to print than standard PLA, with reduced interlayer adhesion and a tendency to clog at higher retraction settings. FiberSilk is described as "incredibly beautiful" in reviews, but plan for more print failures than with Easy PLA.
