Phaetus aeCoating NexABS-GF25 — 25% glass-fiber ABS, 1kg / 1.75mm
A glass-fiber-reinforced ABS engineering filament. What makes the aeCoating line different is its co-extrusion "skin-core" structure: the core is ABS loaded with 25% chopped glass fiber for stiffness and dimensional stability, and it's wrapped in a skin of unfilled ABS. The practical result is the warp resistance and rigidity you want from a GF-filled material, but with the interlayer bonding restored by the unfilled skin — and a clean matte finish with no fiber strands floating on the surface.
Use it where plain ABS isn't stiff enough or warps too much: brackets, jigs and fixtures, motor mounts, enclosures, and functional parts that see heat and load.
Print settings (Phaetus published)
- Nozzle / print temp: 250–270°C
- Bed temp: 100–110°C
- Build surface: PEI or PC film, smooth or textured
- Enclosure: recommended — this is an ABS-based resin, so an enclosed/draft-free chamber prevents warping and layer cracking on larger parts
- Diameter / weight: 1.75mm, 1kg spool
Hardware you need
This filament is abrasive. The 25% glass fiber will chew through a brass nozzle quickly. Phaetus and resellers specify a hardened steel, DLC-coated, tungsten-carbide, or ruby nozzle — run one or your nozzle geometry (and print quality) degrades within a spool. A 0.4mm or larger hardened nozzle is the safe default.
Drying
Glass-fiber ABS absorbs moisture. If the spool has been open or sitting, dry it before printing (roughly 60–70°C for several hours in a filament dryer) — wet GF-ABS prints rough, weak, and stringy.
Honest note: this is a stiff, heat-tolerant engineering material, not a beginner filament. Plan for an enclosure, a hardened nozzle, and dry storage and it rewards you with strong, low-warp functional parts.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
