Printing Parameters
Nozzle temperature°C240–270 (Bambu Lab); 245–265 (Polymaker PolyLite)[7][1]Not documented
Bed temperature°C80–100 (Bambu Lab); 90–100 (Polymaker)[7][1]Not documented
Enclosure / chamber requirement1–5Enclosure 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][20]Actively heated chamber required[21][22]
Recommended chamber temperature°C45–60 (Bambu Lab)[7]Not documented
Part cooling fan0–80 % (Bambu Lab); off (Polymaker PolyLite)[7][1]Not documented
Bed surface & adhesion aidClean the plate and apply glue — Bambu Lab lists glue as the way to improve adhesion and prevent warping[20]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s10–16 (PrusaSlicer guidance for ABS/ASA)[23]Not documented
Warping tendency1–5High — enclosure needed for reliable large parts; Bambu Lab attributes surface cracking to cooling stress exceeding interlayer adhesion[20]Moderate — needs adhesion aid or draught shield; the fibre cuts PEEK's crystallisation shrinkage[3]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[20]Not documented
Stringing / oozing tendency1–5Slight[1]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[20][1]Expert / industrial hardware only[21][22]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[20]Hardened steel required[3]
Abrasiveness1–5Non-abrasive[20]Highly abrasive — standard CF composite[3]
Nozzle clog risk1–5Low — no special hot-end required and clogging is not among the listed drawbacks; Prusa lists no drybox and no hardened nozzle[24][25]High — jams from moisture, heat creep or particles; 3DXTech adds a hardened 0.4 mm minimum nozzle and 0.25 mm layers to the mandatory 120 °C pre-dry[26][27]
Heat-creep / jam sensitivity1–5Slightly sensitive[24]Not documented
Hotend requirementNo special hot-end required[24]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.65 % saturated at 25 °C / 55 % RH (Bambu Lab); Polymaker measures 0.51 % maximum uptake for ABS Pro[7][8]Not documented
Equilibrium moisture content at ~50 % RH%0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[7][8]0.06 in 24 h on extruded CF30 stock (ASTM D570)[6]
Drying temperature & time80 °C for 8 h (Bambu Lab); 70 °C for 6 h (Polymaker)[7][1]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[28]Not documented
Effect of moisture on strengthPolymaker 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[28]No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry before every print because trapped water flashes to steam at these nozzle temperatures[26]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[28]Not documented
Mechanical Properties
Tensile strength (XY)MPa33 ± 3 (Bambu Lab) to 35 (Polymaker ABS Pro and Max) printed XY, ISO 527; 3DXTech quotes 42 at break[7][8][9][29]105 at break (printed XY, ISO 527, CF10); 121 at yield on extruded CF30 stock (ASTM D638)[3][6]
Young's modulusMPa2200 ± 190 (Bambu Lab) to 2330 (Polymaker ABS Pro) printed XY, ISO 527; 3DXTech quotes 1950[7][8][29]8100 (printed XY, ISO 527, CF10) — more than double unfilled PEEK; 6343 on extruded CF30 stock (ASTM D638)[3][6]
Elongation at break%6.7 (ABS Max) to 10.5 (Bambu Lab) at break, printed XY, ISO 527[7][8][9]3 at break (printed XY, ISO 527), against 28 for unfilled PEEK[3][30]
Flexural strengthMPa60 (ABS Pro) to 63 (ABS Max) printed XY, ISO 178; Bambu Lab 62 ± 4; 3DXTech quotes 76[7][8][9][29]136 (printed XY, ISO 178, CF10); 193 on extruded CF30 stock (ASTM D790)[3][6]
Flexural modulusMPa1880 ± 110 (Bambu Lab) to 2500 (ABS Max) printed XY, ISO 178[7][9]8300 (printed XY, ISO 178, CF10); 7171 on extruded CF30 stock (ASTM D790)[3][6]
Charpy impact, notchedkJ/m²10.5 (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][8][9][7]Not documented
Other impact dataCharpy unnotched 39.3 ± 3.6 printed XY (Bambu Lab, ISO 179); notched 21.5 ± 2.2[7]Izod notched 61.9 J/m on extruded CF30 stock, converted from 1.16 ft-lb/in (ASTM D256)[6]
Layer adhesion / Z tensileMPa21.9 (ABS Pro) to 29.7 (PolyLite) printed Z, ISO 527; Bambu Lab 28 ± 2[7][1][8]Not documented
Brittleness1–5Tough — absorbs impact, yields before breaking[7][1]Brittle — snaps with little warning; elongation falls from 28 % to 3 %[3][30]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell M107 on extruded PEEK-CF30 stock (ASTM D785), against M100 unfilled[6][31]
Creep resistance / sustained load1–5Moderate — no printed-ABS creep test found; Tg of 101–126 °C keeps room-temperature service far below softening, unlike PLA[1][8][9]Excellent — holds load for years. Ensinger rates carbon-fibre PEEK stock as very highly creep resistant and specifies 260 °C continuous service[6]
Fatigue / repeated-flex resistance1–5Moderate — no printed-ABS S-N curve found; 10.5 % elongation and 21.5 kJ/m² notched Charpy give far more cyclic tolerance than PLA[7][32]Good. Victrex rates PEEK for long-term fatigue as well as creep; the fibre cuts elongation at break from 28 % to 3 %, which limits repeated large-strain flexing[33][3][30]
Elasticity / flexibility1–5Rigid[7]Rigid[3]
Z strength as % of XY%85 (Bambu Lab, printed Z against XY tensile); 63 for Polymaker ABS Pro[7][8]Not documented
Thermal Properties
HDT at 0.45 MPa°C87 (Bambu Lab) to 118 (Polymaker ABS Max), ISO 75 at 0.45 MPa; PolyLite ABS 100[7][1][9]265 (printed XY, ISO 75 at 0.45 MPa, CarbonX PEEK+CF10) against 140 for unfilled PEEK[3][30]

Glass transition (Tg)°C101 (PolyLite) to 126 (ABS Max), DSC; 105 quoted by 3DXTech[1][9][29]143 (DSC, CarbonX PEEK+CF10) — the fibre does not move the glass transition[3]
Melting point / Vicat°CAmorphous — no melting point; Vicat 104 (PolyLite) to 127 (ABS Max), ISO 306[1][9]334 melting on extruded CF30 stock, converted from 633 °F[6]
Continuous service temperature°C101 measured on a loaded glass-filled ABS bar (My Tech Fun); unfilled ABS is bounded by its 84–98 °C heat deflection[34][7][1]260 long-term on extruded CF30 stock, converted from 500 °F; 300 short term[6]
Annealing responseDecomposition above 380 °C (PolyLite ABS, TGA)[1]Not documented
Thermal expansion (CTE)µm/m·K86 ± 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[35][36]14.4 (extruded PEEK-CF30 stock, ASTM D696; source states 0.80e-5 in/in/°F) — about a third of unfilled PEEK[6][31]
Flammability / UL 94Flammable; no UL 94 rating published for standard ABS, though V-0 grades exist[37][7]UL 94 V-0 on the base resin; Ensinger lists extruded PEEK-CF30 stock as inherently flame resistant[30][6]
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement[19]Not documented
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; poor against strong acids; dissolved by acetone[1]Not documented
Water / humidity resistance in service1–5Good — minor absorption[7]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[19]Not documented
Biodegradability / compostabilityNot biodegradable[19]Not documented
RecyclabilityMechanically recyclable as resin code 9, but not accepted in household plastic collection[19]Not documented
Electrical & ESD propertiesSurface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[29]Surface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[3]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[38][20]Moderate — measurable VOCs and UFPs, ventilation advised. None of these polymers was in the chamber study, and all are processed far above the temperatures it covered[38]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[38]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[38]Not documented
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[38][20]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[38][20]Ventilated room or enclosure recommended[38]
Dust & fibre handling hazardNot documentedCarbon fibre is bound in the matrix; sanding dust should not be inhaled[3]
Post-Processing
Sanding & machiningSands well and takes filler; the usual preparation before painting[19]Not documented
Gluing & solvent weldingSolvent-welds with acetone[1]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works — ABS dissolves in acetone[1]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[39][20]Not documented
Dimensional accuracy & detailWarping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[20]Not documented
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[40][1]95–98 wt% sulphuric acid dissolves the matrix at 40–70 °C and leaves the fibre. Nothing else touches PEEK.[41][40]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[40][42]Concentrated nitric, hydrofluoric, hydrobromic and hydriodic acids attack it; DCM, DMSO and THF swell thin-walled sections.[43][40]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[44]None — no solvent softens PEEK, so parts are joined thermally or mechanically, never chemically.[43][40]
