Densityg/cm³1.04 (ABS Pro) and 1.06 (ABS Max), ISO 1183[1][2]1.17 (measured on a 100 % infill printed part, ISO 1183-A)[4]
Typical priceUSD/kg1 kg spools cluster near 27[5]1 kg spools cluster near 71[6]
Price range across brandsUSD/kg16–30 across brands; SUNLU E-ABS 16, Polymaker ABS Pro 25, YXPOLYER ABS Enhanced 28, Polymaker ABS Max 30[5][7][8]71 — BASF Ultrafuse PC GF30 at igo3d is the only priced listing found; Owens Corning sells XSTRAND GF30-PC in 500 g and 1 kg[6][4]
Market availability1–5Available from several mainstream brands[5]Niche, a handful of specialist brands — neither Polymaker's nor 3DXTech's polycarbonate range contains a glass-fibre grade, but BASF Forward AM and Owens Corning both sell one through European retail[6][4][5][9]
Spool sizes & diameters1.75 and 2.85 mm; 1 kg spools[5]1.75 and 2.85 mm at +/- 0.05 mm; 500 g and 1 kg net spools[4]
Typical applicationsLarge enclosure and automotive parts where plain ABS warps or softens too early[1][2]Functional prototyping for mechanical engineering, electronics and automotive[4]
Diameter tolerance± mmNot documented+/- 0.05 (Owens Corning XSTRAND)[4]
Printing Parameters
Nozzle temperature°C270–290 (ABS Pro); 270–300 (ABS Max) — 25–35 °C above plain ABS[1][2]280-330 (Owens Corning XSTRAND GF30-PC)[4]
Bed temperature°C120 (ABS Max)[2]80-110 (Owens Corning XSTRAND GF30-PC)[4]
Enclosure / chamber requirement1–5Enclosure required (passive)[1][2][10]Enclosure required (passive) — as for unfilled PC[11][10]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[10][12]Perforated plate, DimaFix or Magigoo PC glue (Owens Corning)[4]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sUp to 250 mm/s (ABS Pro) and 200 mm/s (ABS Max), equivalent to 20 and 16 on a 0.4 mm nozzle at 0.2 mm layer[1][2][13]Not documented
Warping tendency1–5High — enclosure needed for reliable large parts[10]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[10]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[14]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; the hotter nozzle rules out PTFE-lined hotends[1][2]Not documented
Extruder requirementNot documentedOwens Corning specifies a nozzle above 0.4 mm and hardened steel nozzles and drive wheels[4]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[10]Hardened steel required — Owens Corning states glass reinforcement shortens brass nozzle and drive-wheel life[4]
Abrasiveness1–5Non-abrasive[10]Highly abrasive — 30 wt% glass fibre[4]
Nozzle clog risk1–5Low — unfilled ABS compound; no special hot-end required and clogging is not among the listed drawbacks[12][15]High — jams from moisture, heat creep or particles; PC already absorbs water from the air and Prusa lists glass-filled composites as a higher clogging risk[16][17]
Heat-creep / jam sensitivity1–5Slightly sensitive[12]Not documented
Hotend requirementNo special hot-end required[12]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.51 % maximum water absorption (ABS Pro)[1]Negligible (<0.1 % EMC) — Owens Corning measures below 0.1 % at 23 °C and 50 % RH (ISO 62)[4]
Equilibrium moisture content at ~50 % RH%0.51 maximum water absorption (Polymaker ABS Pro)[1]Below 0.1 at 23 °C and 50 % RH, and below 0.1 at saturation (ISO 62)[4]
Drying temperature & time70 °C for 6 h (ABS Max)[2]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[18]Not documented
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures[18]No dry-versus-conditioned figures are published. Polymaker calls PC highly hygroscopic; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[19][18]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[18]Not documented
Mechanical Properties
Tensile strength (XY)MPa34.9 (ABS Pro) and 35.7 (ABS Max) printed XY, ISO 527[1][2]65 at break (printed, ISO 527 at 1 mm/min)[4]
Young's modulusMPa2330 (ABS Pro) and 2320 (ABS Max) printed XY, ISO 527[1][2]5400 (printed, ISO 527 at 1 mm/min)[4]
Elongation at break%6.7 (ABS Max) and 7.3 (ABS Pro) at break, printed XY, ISO 527[1][2]2.5 at break (printed, ISO 527 at 1 mm/min)[4]
Flexural strengthMPa60.1 (ABS Pro) and 63.3 (ABS Max) printed XY, ISO 178[1][2]113 at yield (printed, ISO 178 at 2 mm/min)[4]

Charpy impact, notchedkJ/m²10.5 (ABS Max) and 14.5 (ABS Pro) printed XY, ISO 179, notched[1][2]Not documented
Layer adhesion / Z tensileMPa21.9 (ABS Pro) and 25.4 (ABS Max) printed Z, ISO 527[1][2]Not documented
Brittleness1–5Tough — absorbs impact, yields before breaking[1][2]Brittle — snaps with little warning; 2.5 % elongation at break[4]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell 70 (118) — the source does not name the scales and Shore D 79 on extruded unfilled PC stock (ASTM D785, D2240); no figure is published for a glass-fibre grade[20]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 115 °C (ABS Pro) and 126 °C (ABS Max) keeps room-temperature service far below softening[1][2]Excellent — holds load for years. Room-temperature tensile creep of moulded unfilled PC ran unbroken at 41 MPa until the test was stopped, and 30 wt% glass raises the tensile modulus from about 2.3 to 5.4 GPa[21][4]
Fatigue / repeated-flex resistance1–5Moderate — no S-N curve found; 6.7–7.3 % elongation and 10.5–14.5 kJ/m² notched Charpy, below unfilled Bambu Lab ABS[1][2][22]Not documented
Elasticity / flexibility1–5Rigid[1]Rigid[4]
Z strength as % of XY%63 (ABS Pro) and 71 (ABS Max), printed[1][2]Not documented
Thermal Properties
HDT at 0.45 MPa°C106.4 (ABS Pro) and 118.1 (ABS Max), ISO 75 at 0.45 MPa[1][2]Not documented
HDT at 1.8 MPa°C101.4 (ABS Pro) and 113.1 (ABS Max), ISO 75 at 1.8 MPa[1][2]137 (printed, ISO 75 Method A at 1.8 MPa)[4]
Glass transition (Tg)°C114.9 (ABS Pro) and 126.3 (ABS Max), DSC[1][2]145 (DSC, ISO 11357)[4]
Melting point / Vicat°CAmorphous — no melting point; Vicat 116.1 (ABS Pro) and 127.4 (ABS Max), ISO 306[1][2]270 stated as melting point (ISO 11357) — unusual for an amorphous polymer, but this is the published figure[4]
Thermal expansion (CTE)µm/m·K86–89 for printed unfilled ABS (fibre Bragg grating, 25–50 °C); no grade-specific measurement published[23]26.2 in XY and 77.4 in Z (printed, ISO 11359-2) — a threefold anisotropy, and the lowest in-plane expansion of any polycarbonate here[4]
Flammability / UL 94Not documentedUL 94 V-0 verified (Owens Corning)[4]
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement[14]Good — years with some colour shift. Owens Corning lists UV resistance as a product benefit but publishes no exposure data[4]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[3]Not documented
Water / humidity resistance in service1–5Not documentedExcellent — essentially unaffected; below 0.1 % water at saturation (ISO 62)[4]
Food contactNot food safe — Polymaker cites potential chemical leaching[14]Not documented
Biodegradability / compostabilityNot biodegradable[14]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[14]Not documented
Electrical & ESD propertiesNot documentedElectrically insulating (Owens Corning)[4]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[24][10]Moderate — measurable VOCs and UFPs, ventilation advised[24]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[24]Not documented
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[24]≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[24]
Hazardous species emittedStyrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[24][10]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[24][10]Ventilated room or enclosure recommended[24][10]
Dust & fibre handling hazardNot documentedOwens Corning warns that the glass reinforcement is abrasive when melted and advises sufficient ventilation and avoiding extrusion fumes[4]
Post-Processing
Sanding & machiningSands well and takes filler before painting[14]Not documented
Painting & finishingPaints readily after light abrasion[14]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works[3]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[25][10]Not documented
Dimensional accuracy & detailNot documentedHigh dimensional stability is the headline benefit; the 26.2 um/m*K in-plane CTE is a third of unfilled PC's[4]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[26][3]Dichloromethane and chloroform dissolve the matrix and leave the fibre; DMF and dioxane do the same (Covestro).[27]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[26][28]Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[27]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[29]Dichloromethane cement welds the resin, but the fibre keeps the joint from flowing closed. Controlled carcinogen.[30]
