Bed temperature°C120 (ABS Max)[2]90–110 (Bambu Lab); 90–105 (Polymaker)[5][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][12]24 at Bambu Lab's 300 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[5][12]
Warping tendency1–5High — enclosure needed for reliable large parts[10]Severe — heated chamber needed[4][10]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[10]Needs a specific surface plus adhesive[13][14]
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[15]Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[14]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; the hotter nozzle rules out PTFE-lined hotends[1][2]Advanced — enclosure, hardware upgrades, tuning[5][10]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[10]Brass fine indefinitely[10]
Abrasiveness1–5Non-abrasive[10]Non-abrasive[4]
Nozzle clog risk1–5Low — unfilled ABS compound; no special hot-end required and clogging is not among the listed drawbacks[11][16]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a 6 h pre-dry at 80 °C[17]
Heat-creep / jam sensitivity1–5Slightly sensitive[11]Slightly sensitive[13]
Hotend requirementNo special hot-end required[11]All-metal hot end required (Simplify3D)[13]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.51 % maximum water absorption (ABS Pro)[1]Low (0.1–0.3 %) — 0.12 % saturated at 25 °C / 55 % RH (Bambu Lab), half that of unfilled Bambu Lab PC[5][18]
Equilibrium moisture content at ~50 % RH%0.51 maximum water absorption (Polymaker ABS Pro)[1]0.12 saturated at 25 °C / 55 % RH (Bambu Lab)[5]
Drying temperature & time70 °C for 6 h (ABS Max)[2]75 °C for 6 h (Polymaker)[4]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[19]Bubbling and popping at the nozzle, stringing and a rough surface[19]
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures[19]No dry-versus-conditioned figures are published. Polymaker calls PC highly hygroscopic and requires a 70–80 °C dry for 6–8 h; run wet, the loss shows as surface defects and poor layer adhesion[14][19]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[19]Airtight containers with desiccant to prevent reabsorption[14]
Mechanical Properties
Tensile strength (XY)MPa34.9 (ABS Pro) and 35.7 (ABS Max) printed XY, ISO 527[1][2]60 ± 4 (Bambu Lab) and 67 ± 4.5 (Polymaker) printed XY, ISO 527[5][4]
Young's modulusMPa2330 (ABS Pro) and 2320 (ABS Max) printed XY, ISO 527[1][2]1670 ± 40 (Bambu Lab) and 2634 ± 182 (Polymaker) printed XY, ISO 527[5][4]
Elongation at break%6.7 (ABS Max) and 7.3 (ABS Pro) at break, printed XY, ISO 527[1][2]2.4 ± 0.3 (Bambu Lab) and 3.49 ± 0.7 (Polymaker) at break, printed XY, ISO 527 — the retardant roughly halves unfilled PC's elongation[5][4][20]
Flexural strengthMPa60.1 (ABS Pro) and 63.3 (ABS Max) printed XY, ISO 178[1][2]96.6 ± 1.3 printed XY, ISO 178 (Polymaker)[4]
Flexural modulusMPa2330 (ABS Pro) and 2500 (ABS Max) printed XY, ISO 178[1][2]2518 ± 53 printed XY, ISO 178 (Polymaker)[4]
Charpy impact, notchedkJ/m²10.5 (ABS Max) and 14.5 (ABS Pro) printed XY, ISO 179, notched[1][2]11.7 ± 1.6 printed XY, ISO 179, notched (Polymaker)[4]
Other impact dataNot documentedNotched Charpy 7.5 ± 1.6 kJ/m² at −30 °C printed XY (Polymaker, ISO 179-1/1eA)[4]
Layer adhesion / Z tensileMPa21.9 (ABS Pro) and 25.4 (ABS Max) printed Z, ISO 527[1][2]21 ± 3 (Bambu Lab) and 46 ± 4.8 (Polymaker) printed Z, ISO 527[5][4]
Brittleness1–5Tough — absorbs impact, yields before breaking[1][2]Moderate[5][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 flame-retardant filament[21]
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]Good. Moulded unfilled PC sustained 41 MPa tensile creep at room temperature without breaking, but the retardant package drops the glass transition to 115 °C in Polymaker's grade, so the unfilled rating is not carried over in full[22][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][23]Not documented

Continuous service temperature°CNot documented113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[24]
Thermal expansion (CTE)µm/m·K86–89 for printed unfilled ABS (fibre Bragg grating, 25–50 °C); no grade-specific measurement published[25]68.4 on extruded unfilled PC stock (ASTM D696; source states 3.8e-5 in/in/°F); no figure is published for a flame-retardant grade[21]
Flammability / UL 94Not documentedUL 94 V-0 (Polymaker PolyMax PC-FR); 3DXTech rates its FR PC/ABS V-0 at 1.5 mm on the base resin[4][26]
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement[15]Degrades within weeks outdoors unless stabilised[14]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[3]Withstands oils, solvents and fuels; Polymaker rates it good against weak acids[14]

Biodegradability / compostabilityNot biodegradable[15]Not biodegradable[14]
RecyclabilityMechanically recyclable but not accepted in household plastic collection[15]Mechanically recyclable but not accepted in household plastic collection[14]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[27][10]Moderate — measurable VOCs and UFPs, ventilation advised[27]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[27]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[27]≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[27]
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[27][10]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[27][10]Ventilated room or enclosure recommended[27][10]
Post-Processing
Sanding & machiningSands well and takes filler before painting[15]Sands and machines well; the toughness means it cuts rather than chips[13]
Painting & finishingPaints readily after light abrasion[15]Not documented
Gluing & solvent weldingNot documentedCyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[13]
Vapour / chemical smoothingAcetone vapour smoothing works[3]No practical vapour smoothing[13]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[28][10]Prints its own supports; 3DXTech sells a dedicated PC break-away support[13]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[29][3]Dichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[30]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[29][31]Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[30]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[32]Dichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[33]
