| Densityg/cm³ | 1.04 (Polymaker PolyLite ABS and ABS Pro) to 1.06 (ABS Max), ISO 1183; Bambu Lab 1.05[4][1][5][6] | 1.17 (measured on a 100 % infill printed part, ISO 1183-A)[3] |
| Typical priceUSD/kg | 1 kg spools cluster near 20[7][8][9][10][11] | 1 kg spools cluster near 71[12] |
| Price range across brandsUSD/kg | 12–45 across brands; IEMAI 12, SUNLU 12 at a 3 kg minimum, ELEGOO 15 in a 5 kg pack, Polymaker 19, YXPOLYER 20, Bambu Lab 20, Push Plastic 25, 3DXTech 45[7][8][13][14][9][10][11][15] | 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[12][3] |
| Market availability1–5 | Ubiquitous, every brand and retailer[7][8][13][14] | 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[12][3][8][13] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 1, 5 and 10 kg spools[13][14] | 1.75 and 2.85 mm at +/- 0.05 mm; 500 g and 1 kg net spools[3] |
| Typical applications | Enclosures, automotive interior parts and tooling that must hold shape above PLA's 55 °C ceiling[1][16] | Functional prototyping for mechanical engineering, electronics and automotive[3] |
| Diameter tolerance± mm | Not documented | +/- 0.05 (Owens Corning XSTRAND)[3] |
| Printing Parameters | ||
| Nozzle temperature°C | 240–270 (Bambu Lab); 245–265 (Polymaker PolyLite)[4][1] | 280-330 (Owens Corning XSTRAND GF30-PC)[3] |
| Bed temperature°C | 80–100 (Bambu Lab); 90–100 (Polymaker)[4][1] | 80-110 (Owens Corning XSTRAND GF30-PC)[3] |
| Enclosure / chamber requirement1–5 | Enclosure recommended — Polymaker calls a chamber needed at ambient temperature, Bambu Lab requires an enclosed printer and rules out its P1P and A-series machines[1][17] | Enclosure required (passive) — as for unfilled PC[18][17] |
| Recommended chamber temperature°C | 45–60 (Bambu Lab)[4] | Not documented |
| Part cooling fan | 0–80 % (Bambu Lab); off (Polymaker PolyLite)[4][1] | Not documented |
| Bed surface & adhesion aid | Clean the plate and apply glue — Bambu Lab lists glue as the way to improve adhesion and prevent warping[17] | Perforated plate, DimaFix or Magigoo PC glue (Owens Corning)[3] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 10–16 (PrusaSlicer guidance for ABS/ASA)[19] | Not documented |
| Warping tendency1–5 | High — enclosure needed for reliable large parts; Bambu Lab attributes surface cracking to cooling stress exceeding interlayer adhesion[17] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[17] | Not documented |
| Stringing / oozing tendency1–5 | Slight[1] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[17][1] | Not documented |
| Extruder requirement | Not documented | Owens Corning specifies a nozzle above 0.4 mm and hardened steel nozzles and drive wheels[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[17] | Hardened steel required — Owens Corning states glass reinforcement shortens brass nozzle and drive-wheel life[3] |
| Abrasiveness1–5 | Non-abrasive[17] | Highly abrasive — 30 wt% glass fibre[3] |
| Nozzle clog risk1–5 | Low — no special hot-end required and clogging is not among the listed drawbacks; Prusa lists no drybox and no hardened nozzle[20][21] | 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[22][23] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[20] | Not documented |
| Hotend requirement | No special hot-end required[20] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 0.65 % saturated at 25 °C / 55 % RH (Bambu Lab); Polymaker measures 0.51 % maximum uptake for ABS Pro[4][5] | Negligible (<0.1 % EMC) — Owens Corning measures below 0.1 % at 23 °C and 50 % RH (ISO 62)[3] |
| Equilibrium moisture content at ~50 % RH% | 0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[4][5] | Below 0.1 at 23 °C and 50 % RH, and below 0.1 at saturation (ISO 62)[3] |
| Drying temperature & time | 80 °C for 8 h (Bambu Lab); 70 °C for 6 h (Polymaker)[4][1] | Not documented |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[24] | Not documented |
| Effect of moisture on strength | Polymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; the loss appears as poor layer adhesion and surface defects rather than a stated strength delta[24] | 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[25][24] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[24] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 33 ± 3 (Bambu Lab) to 35 (Polymaker ABS Pro and Max) printed XY, ISO 527; 3DXTech quotes 42 at break[4][5][6][26] | 65 at break (printed, ISO 527 at 1 mm/min)[3] |
| Young's modulusMPa | 2200 ± 190 (Bambu Lab) to 2330 (Polymaker ABS Pro) printed XY, ISO 527; 3DXTech quotes 1950[4][5][26] | 5400 (printed, ISO 527 at 1 mm/min)[3] |
| Elongation at break% | 6.7 (ABS Max) to 10.5 (Bambu Lab) at break, printed XY, ISO 527[4][5][6] | 2.5 at break (printed, ISO 527 at 1 mm/min)[3] |
| Flexural strengthMPa | 60 (ABS Pro) to 63 (ABS Max) printed XY, ISO 178; Bambu Lab 62 ± 4; 3DXTech quotes 76[4][5][6][26] | 113 at yield (printed, ISO 178 at 2 mm/min)[3] |
| Flexural modulusMPa | 1880 ± 110 (Bambu Lab) to 2500 (ABS Max) printed XY, ISO 178[4][6] | 5500 (printed, ISO 178 at 2 mm/min)[3] |
| Charpy impact, notchedkJ/m² | 10.5 (ABS Max) and 14.5 (ABS Pro) printed XY, ISO 179, notched; PolyLite ABS 18.0 ± 0.9 and Bambu Lab 21.5 ± 2.2[1][5][6][4] | Not documented |
| Other impact data | Charpy unnotched 39.3 ± 3.6 printed XY (Bambu Lab, ISO 179); notched 21.5 ± 2.2[4] | Not documented |
| Layer adhesion / Z tensileMPa | 21.9 (ABS Pro) to 29.7 (PolyLite) printed Z, ISO 527; Bambu Lab 28 ± 2[4][1][5] | Not documented |
| Brittleness1–5 | Tough — absorbs impact, yields before breaking[4][1] | Brittle — snaps with little warning; 2.5 % elongation at break[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell 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[27] |
| Creep resistance / sustained load1–5 | Moderate — no printed-ABS creep test found; Tg of 101–126 °C keeps room-temperature service far below softening, unlike PLA[1][5][6] | 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[28][3] |
| Fatigue / repeated-flex resistance1–5 | Moderate — no printed-ABS S-N curve found; 10.5 % elongation and 21.5 kJ/m² notched Charpy give far more cyclic tolerance than PLA[4][29] | Not documented |
| Elasticity / flexibility1–5 | Rigid[4] | Rigid[3] |
| Z strength as % of XY% | 85 (Bambu Lab, printed Z against XY tensile); 63 for Polymaker ABS Pro[4][5] | Not documented |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 87 (Bambu Lab) to 118 (Polymaker ABS Max), ISO 75 at 0.45 MPa; PolyLite ABS 100[4][1][6] | Not documented |
| HDT at 1.8 MPa°C | 84 (Bambu Lab) to 113 (Polymaker ABS Max), ISO 75 at 1.8 MPa; PolyLite ABS 98[4][1][6] | 137 (printed, ISO 75 Method A at 1.8 MPa)[3] |
| Glass transition (Tg)°C | 101 (PolyLite) to 126 (ABS Max), DSC; 105 quoted by 3DXTech[1][6][26] | 145 (DSC, ISO 11357)[3] |
| Melting point / Vicat°C | Amorphous — no melting point; Vicat 104 (PolyLite) to 127 (ABS Max), ISO 306[1][6] | 270 stated as melting point (ISO 11357) — unusual for an amorphous polymer, but this is the published figure[3] |
| Continuous service temperature°C | 101 measured on a loaded glass-filled ABS bar (My Tech Fun); unfilled ABS is bounded by its 84–98 °C heat deflection[30][4][1] | Not documented |
| Annealing response | Decomposition above 380 °C (PolyLite ABS, TGA)[1] | Not documented |
| Thermal expansion (CTE)µm/m·K | 86 ± 3 at 0° and 89 ± 3 at 90° raster (printed, fibre Bragg grating, 25–50 °C); 82 for a neat large-format bead at 30 °C[31][32] | 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[3] |
| Flammability / UL 94 | Flammable; no UL 94 rating published for standard ABS, though V-0 grades exist[33][4] | UL 94 V-0 verified (Owens Corning)[3] |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement[16] | Good — years with some colour shift. Owens Corning lists UV resistance as a product benefit but publishes no exposure data[3] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; poor against strong acids; dissolved by acetone[1] | Not documented |
| Water / humidity resistance in service1–5 | Good — minor absorption[4] | Excellent — essentially unaffected; below 0.1 % water at saturation (ISO 62)[3] |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[16] | Not documented |
| Biodegradability / compostability | Not biodegradable[16] | Not documented |
| Recyclability | Mechanically recyclable as resin code 9, but not accepted in household plastic collection[16] | Not documented |
| Electrical & ESD properties | Surface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[26] | Electrically insulating (Owens Corning)[3] |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[34][17] | Moderate — measurable VOCs and UFPs, ventilation advised[34] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[34] | Not documented |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[34] | ≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[34] |
| Hazardous species emitted | Styrene 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[34][17] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[34][17] | Ventilated room or enclosure recommended[34][17] |
| Dust & fibre handling hazard | Not documented | Owens Corning warns that the glass reinforcement is abrasive when melted and advises sufficient ventilation and avoiding extrusion fumes[3] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler; the usual preparation before painting[16] | Not documented |
| Gluing & solvent welding | Solvent-welds with acetone[1] | Not documented |
| Vapour / chemical smoothing | Acetone vapour smoothing works — ABS dissolves in acetone[1] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[35][17] | Not documented |
| Dimensional accuracy & detail | Warping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[17] | High dimensional stability is the headline benefit; the 26.2 um/m*K in-plane CTE is a third of unfilled PC's[3] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[36][1] | Dichloromethane and chloroform dissolve the matrix and leave the fibre; DMF and dioxane do the same (Covestro).[37] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[36][38] | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[37] |
| Solvent welding & smoothing agent | Acetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[39] | Dichloromethane cement welds the resin, but the fibre keeps the joint from flowing closed. Controlled carcinogen.[40] |
