Bed temperature°C80–100 (Bambu Lab); 90–100 (Polymaker)[4][1]130–150 (3DXTech)[3]
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)[4]Not documented
Part cooling fan0–80 % (Bambu Lab); off (Polymaker PolyLite)[4][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]Severe — heated chamber needed[21]
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]Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[21]
Abrasiveness1–5Non-abrasive[20]Non-abrasive when unfilled[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]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry before every print[26]
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[4][5]Not documented
Equilibrium moisture content at ~50 % RH%0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[4][5]0.37 in 24 h and 1.1 at saturation on extruded stock (ASTM D570)[27]

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

Elongation at break%6.7 (ABS Max) to 10.5 (Bambu Lab) at break, printed XY, ISO 527[4][5][6]3 (printed, ISO 527 and ASTM D638) against 60 on extruded stock — printing costs PPSU almost all of its ductility[3][7][27]
Flexural strengthMPa60 (ABS Pro) to 63 (ABS Max) printed XY, ISO 178; Bambu Lab 62 ± 4; 3DXTech quotes 76[4][5][6][29]110 (printed, ISO 178 and ASTM D790, 3DXTech and Stratasys PPSF agree); 91 on extruded stock[3][7][27]
Flexural modulusMPa1880 ± 110 (Bambu Lab) to 2500 (ABS Max) printed XY, ISO 178[4][6]2200 (printed, ASTM D790, Stratasys PPSF) and 2215 (printed XY, ISO 178, 3DXTech)[3][7]

Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell M86 on printed PPSF (ASTM D785, Stratasys); M96 on extruded PPSU stock (and an unlabelled 123)[7][27]
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][5][6]Good. Printed PPSF holds 189 °C heat deflection at 1.8 MPa (ASTM D648) and extruded stock is rated 149 °C long-term service, but Ensinger does not claim the creep resistance it claims for PSU and PPS[7][27]

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]Withstands repeated steam autoclaving, the usual reason to choose PPSU over PSU; Stratasys also lists PPSF as passing 24 h stress-crack exposure to antifreeze, petrol, motor oil, power-steering, transmission and washer fluid at 23 °C and 100 °C[3][7]
Water / humidity resistance in service1–5Good — minor absorption[4]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]Volume resistivity 5e13 to 1.5e14 ohm-cm and dielectric strength 80-290 V/mil on printed PPSF (ASTM D257, D149)[7]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[35][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[35]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[35]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[35]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[35][20]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[35][20]Ventilated room or enclosure recommended[35]
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[36][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.[37][1]Dichloromethane dissolves it at 23 °C at every stress level; acetone solvates and softens unstressed PPSU (Solvay ESCR).[38]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[37][39]MEK ruptures stressed parts and toluene crazes them above 13.8 MPa; glass-filled grades survive where unfilled craze.[38]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[40]Dichloromethane cements PPSU and NMP softens residual resin; both are laboratory reagents, not workshop stock.[38]
