Densityg/cm³1.18 (ISO 1183) — above unfilled ABS at 1.05 because of the retardant loading[1][4]1.28 (ISO 1183, 3DXTech) and 1.33 (ISO 1183, Spectrum PPS AM230)[2][5]

Printing Parameters
Nozzle temperature°CNot documented335-345 (3DXTech printed-specimen conditions); 300-330 (Spectrum)[2][5]
Bed temperature°CNot documented110-130 (3DXTech); 100-120 (Spectrum)[2][5]
Enclosure / chamber requirement1–5Enclosure recommended[12]Actively heated chamber required[13][14]
Recommended chamber temperature°CNot documented60-80 actively heated (Spectrum PPS AM230)[5]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[12][15]Adhesive required — Spectrum specifies Magigoo Pro HT[5]
Warping tendency1–5High — enclosure needed for reliable large parts[12]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[12]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[16]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[12]Expert / industrial hardware only[13][14]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[12]Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[13]
Abrasiveness1–5Non-abrasive[1]Non-abrasive when unfilled[2]
Nozzle clog risk1–5Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its FR-ABS, only an 80 °C pre-dry[17]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 110 °C pre-dry before every print[18]
Heat-creep / jam sensitivity1–5Slightly sensitive[15]Not documented
Hotend requirementNo special hot-end required[15]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[4][19][17]Negligible (<0.1 % EMC) — Polymaker states minimal water absorption at 0.05 %[3]
Equilibrium moisture content at ~50 % RH%Not documented0.01 in 24 h on extruded stock (ASTM D570) — effectively non-absorbing[20]
Drying temperature & timeNot documentedAt least 3 h at 90 °C in hot dry air if the filament has taken up moisture (Spectrum)[5]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[21]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[21]Little to measure — equilibrium uptake is 0.05 %; 3DXTech still specifies a 110 °C, 4 h pre-dry before printing[3][18]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[21]Not documented
Mechanical Properties
Tensile strength (XY)MPa45 at break (printed XY, ISO 527)[1]50 at break (printed XY, ISO 527, 3DXTech); 65 at break injection-moulded (ISO 527, Spectrum); 94 at yield on extruded stock (ASTM D638)[2][5][20]
Young's modulusMPa1990 (printed XY, ISO 527)[1]2650 (printed XY, ISO 527, 3DXTech); 3650 injection-moulded (ISO 527, Spectrum); 5769 on extruded stock (ASTM D638)[2][5][20]
Elongation at break%4 at break (printed XY, ISO 527) — well below the 10 % of unfilled 3DXTech ABS[1][22]18 at break (printed XY, ISO 527, 3DXTech) against 2.0 injection-moulded (Spectrum) and 2.5 on extruded stock — the suppliers disagree by nearly an order of magnitude[2][5][20]
Flexural strengthMPa80 (printed XY, ISO 178)[1]52 (printed XY, ISO 178, 3DXTech); 141 on extruded stock (ASTM D790)[2][20]
Flexural modulusMPa2250 (printed XY, ISO 178)[1]2540 (printed XY, ISO 178)[2]
Charpy impact, notchedkJ/m²Not documented1.3 notched injection-moulded (ISO 179-1eA, Spectrum); unnotched 18[5]
Other impact dataNot documentedIzod notched 33 J/m on extruded PPS stock, converted from 0.62 ft-lb/in (ASTM D256)[20]
Brittleness1–5Moderate — elongation at break falls to 4 % from 10 % for the unfilled grade[1][22]Moderate[2]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell 105 (and R124) on extruded PPS stock (ASTM D785)[20]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1][22]Excellent — holds load for years. Ensinger lists high creep resistance as a headline property of extruded PPS stock, and Spectrum states that rigidity, strength and creep resistance are unchanged under continuous load at high temperature[20][5]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break falls to 4 % against 10 % for unfilled 3DXTech ABS[1][22]Not documented
Elasticity / flexibility1–5Rigid[1]Rigid[2]
Thermal Properties
HDT at 0.45 MPa°CNot documented90 (printed XY, ISO 75 at 0.45 MPa, 3DXTech); 129 injection-moulded (ISO 75, Spectrum); 204 on extruded stock (ASTM D648 at 66 psi)[2][5][20]
HDT at 1.8 MPa°CNot documented107 injection-moulded (ISO 75 at 1.81 MPa, Spectrum); 104 on extruded stock (ASTM D648 at 264 psi)[5][20]
Glass transition (Tg)°C105 (DSC)[1]Not documented
Melting point / Vicat°CNot documented283 melting (ISO 11357, 3DXTech) and 280 on extruded stock; Vicat softening 236 at 50 N injection-moulded (ISO 306, Spectrum)[2][5][20]
Continuous service temperature°CNot documented170 long-term service on extruded PPS stock, converted from 338 °F[20]
Thermal expansion (CTE)µm/m·KNot documented59.4 (extruded PPS stock, 22-60 °C, ASTM D696; source states 3.3e-5 in/in/°F)[20]
Flammability / UL 94UL 94 V-0 at 1.5 mm, rated on the base resin rather than the printed part[1]UL 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[23]Outstanding — PPS resists essentially all solvents below 200 °C[3]
Water / humidity resistance in service1–5Not documentedExcellent — essentially unaffected; extruded stock takes up 0.01 % water in 24 h[20]
Food contactNot food safe — Polymaker cites potential chemical leaching[16]Not documented
Biodegradability / compostabilityNot biodegradable[16]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[16]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[24][12]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[24]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[24]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[24]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[24][12]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[24][12]Ventilated room or enclosure recommended[24]
Post-Processing
Sanding & machiningSands well and takes filler before painting[16]Not documented
Painting & finishingPaints readily after light abrasion[16]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[25][12]Not documented
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[26][23]None — PPS does not dissolve in any known solvent below 200 °C.[27][26]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[26][28]Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[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.[29]None — no solvent welds or smooths PPS.[27]
