Printing Parameters
Bed temperature°CNot documented130–150 (3DXTech)[2]
Enclosure / chamber requirement1–5Enclosure recommended[10]Actively heated chamber required[11][12]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[10][13]Not documented
Warping tendency1–5High — enclosure needed for reliable large parts[10]Severe — heated chamber needed[11]
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[10]Expert / industrial hardware only[11][12]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[11]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Non-abrasive when unfilled[2]
Nozzle clog risk1–5Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-ABS, only an 80 °C pre-dry[15]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry before every print[16]
Heat-creep / jam sensitivity1–5Slightly sensitive[13]Not documented
Hotend requirementNo special hot-end required[13]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — the ABS matrix takes up 0.51–0.65 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 80 °C, 4 h pre-dry[17][18][15]Not documented
Equilibrium moisture content at ~50 % RH%Not documented0.37 in 24 h and 1.1 at saturation on extruded stock (ASTM D570)[19]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[20]Not documented
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[20]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[16]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[20]Not documented
Mechanical Properties
Tensile strength (XY)MPa58 at break (printed XY, ISO 527) — the conductive filler raises strength above the unfilled grade's 42[1][21]55 (printed XY, ISO 527, 3DXTech) and 55 (printed on side long edge, ASTM D638, Stratasys PPSF); 79 at yield on extruded stock[2][3][19]
Young's modulusMPa2130 (printed XY, ISO 527)[1]2100 (printed, ASTM D638, Stratasys PPSF) and 2310 (printed XY, ISO 527, 3DXTech); 2344 on extruded stock[2][3][19]
Elongation at break%4 at break (printed XY, ISO 527)[1]3 (printed, ISO 527 and ASTM D638) against 60 on extruded stock — printing costs PPSU almost all of its ductility[2][3][19]
Flexural strengthMPa80 (printed XY, ISO 178)[1]110 (printed, ISO 178 and ASTM D790, 3DXTech and Stratasys PPSF agree); 91 on extruded stock[2][3][19]
Flexural modulusMPa2275 (printed XY, ISO 178)[1]2200 (printed, ASTM D790, Stratasys PPSF) and 2215 (printed XY, ISO 178, 3DXTech)[2][3]
Other impact dataNot documentedIzod notched 58.7 J/m and unnotched 165.5 J/m (printed, ASTM D256 Method A, Stratasys PPSF); 160 J/m notched on extruded stock[3][19]
Brittleness1–5Moderate[1]Brittle — snaps with little warning[2]
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)[3][19]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1]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[3][19]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break 4 %, well below unfilled ABS[1][21]Not documented
Elasticity / flexibility1–5Rigid[1]Rigid[2]
Thermal Properties
HDT at 0.45 MPa°CNot documented190 (printed XY, ISO 75 at 0.45 MPa, 3DXTech)[2]
HDT at 1.8 MPa°CNot documented189 (printed, ASTM D648 at 264 psi, Stratasys PPSF); 207 on extruded stock, converted from 405 °F[3][19]
Glass transition (Tg)°C105 (DSC)[1]230 (DSC) — the highest glass transition in the dataset[2]
Continuous service temperature°CNot documented149 long-term service on extruded PPSU stock, converted from 300 °F[19]
Thermal expansion (CTE)µm/m·KNot documented55.0 (printed PPSF, ASTM D696; source states 5.5e-5 mm/mm/°C) and 55.8 on extruded stock (ASTM D696, from 3.1e-5 in/in/°F)[3][19]
Flammability / UL 94Not documentedUL 94 V-0 at 1.5 mm, rated on the base resin[2]
Environment & Chemical
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[22]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[2][3]
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 propertiesSurface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ABS[1][21]Volume resistivity 5e13 to 1.5e14 ohm-cm and dielectric strength 80-290 V/mil on printed PPSF (ASTM D257, D149)[3]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[23][10]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[23]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[23]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[23]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[23][10]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[23][10]Ventilated room or enclosure recommended[23]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[14]Not documented
Painting & finishingPaints readily after light abrasion[14]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[24][10]Not documented
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[25][22]Dichloromethane dissolves it at 23 °C at every stress level; acetone solvates and softens unstressed PPSU (Solvay ESCR).[26]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[25][27]MEK ruptures stressed parts and toluene crazes them above 13.8 MPa; glass-filled grades survive where unfilled craze.[26]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[28]Dichloromethane cements PPSU and NMP softens residual resin; both are laboratory reagents, not workshop stock.[26]
