Printing Parameters
Bed temperature°CNot documented130–150 (3DXTech)[2]
Enclosure / chamber requirement1–5Enclosure recommended[13]Actively heated chamber required[14][15]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[13][16]Not documented
Warping tendency1–5Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ABS[13]Severe — heated chamber needed[14]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[13]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[17]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[13]Expert / industrial hardware only[14][15]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[13]Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[14]
Abrasiveness1–5Highly abrasive — standard CF composite[13]Non-abrasive when unfilled[2]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened nozzle of 0.4 mm minimum and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[18][19][20]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry before every print[21]
Heat-creep / jam sensitivity1–5Slightly sensitive[16]Not documented
Hotend requirementNo special hot-end required[16]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[22][23][18]Not documented
Equilibrium moisture content at ~50 % RH%Not documented0.37 in 24 h and 1.1 at saturation on extruded stock (ASTM D570)[24]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[25]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[25]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[21]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[25]Not documented
Mechanical Properties
Tensile strength (XY)MPa46 at break (printed XY, ISO 527)[1]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][24]
Young's modulusMPa5210 (printed XY, ISO 527) — more than double unfilled ABS[1]2100 (printed, ASTM D638, Stratasys PPSF) and 2310 (printed XY, ISO 527, 3DXTech); 2344 on extruded stock[2][3][24]
Elongation at break%2 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][24]
Flexural strengthMPa76 (printed XY, ISO 178)[1]110 (printed, ISO 178 and ASTM D790, 3DXTech and Stratasys PPSF agree); 91 on extruded stock[2][3][24]
Flexural modulusMPa5260 (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][24]
Brittleness1–5Brittle — snaps with little warning; elongation at break 2 %[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][24]
Creep resistance / sustained load1–5Good — no creep test found; chopped carbon fibre restrains matrix flow and modulus rises to 5210 MPa against 2200–2330 for unfilled ABS[1][22][23]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][24]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break falls to 2 % against 10.5 % for unfilled ABS[1][22]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][24]
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[24]
Thermal expansion (CTE)µm/m·K19–25 along the print bead and 80–84 in the build direction at 30 °C (20 wt% CF, large-format printed, TMA)[26]55.0 (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][24]
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[27]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[17]Not documented
Biodegradability / compostabilityNot biodegradable[17]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[17]Not documented
Electrical & ESD propertiesSurface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1]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[28][13]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[28]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[28]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[28]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[28][13]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[28][13]Ventilated room or enclosure recommended[28]
Dust & fibre handling hazardCarbon fibre is bound in the matrix; sanding dust should not be inhaled[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[17]Not documented
Painting & finishingPaints readily after light abrasion[17]Not documented
Vapour / chemical smoothingAcetone smoothing is blunted by the fibre — only the resin fraction dissolves[27]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[29][13]Not documented
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[30][27]Dichloromethane dissolves it at 23 °C at every stress level; acetone solvates and softens unstressed PPSU (Solvay ESCR).[31]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[30][32]MEK ruptures stressed parts and toluene crazes them above 13.8 MPa; glass-filled grades survive where unfilled craze.[31]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[33][27]Dichloromethane cements PPSU and NMP softens residual resin; both are laboratory reagents, not workshop stock.[31]
