| Identity & Market | ||
| Base polymer / chemistry | Polyphenylene sulfide — a semi-crystalline high-temperature polymer[1][2] | Styrene-ethylene-butadiene-styrene thermoplastic elastomer — a styrenic rubber, not a polyurethane[3] |
| Densityg/cm³ | 1.28 (ISO 1183, 3DXTech) and 1.33 (ISO 1183, Spectrum PPS AM230)[1][4] | 1.044 printed part density (BASF Ultrafuse TPS 90A, ISO 1183-1) — the lightest elastomer here[3] |
| Typical priceUSD/kg | 1 kg-equivalent spools span 84–200; the middle of the market is about 117[5][6][7] | 1 kg-equivalent spools cluster near 77[8] |
| Price range across brandsUSD/kg | 84-200 across brands and diameters; IEMAI 3D 84 at 1 kg, Spectrum PPS AM230 117 at 750 g, 3DXTech ThermaX PPS 140 at 2.85 mm and 200 at 1.75 mm[5][6][7] | 77 for the Recreus 600 g spool; Proto-pasta only lists a 50 g coil, which prices at 120[8][9] |
| Market availability1–5 | Niche, a handful of specialist brands[5][6] | Niche, a handful of specialist brands[3][9][8] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 500 g and 750 g spools[5][6] | 1.75 and 2.85 mm; 0.05 and 0.6 kg spools[3][8] |
| Typical applications | Chemical-plant and under-bonnet parts needing solvent resistance above 200 °C[2] | Soft-touch overmoulds and skin-contact parts where a non-polyurethane elastomer is wanted[3] |
| Printing Parameters | ||
| Nozzle temperature°C | 335-345 (3DXTech printed-specimen conditions); 300-330 (Spectrum)[1][4] | 260–280 (BASF Ultrafuse TPS 90A) — far hotter than any TPU here[3] |
| Bed temperature°C | 110-130 (3DXTech); 100-120 (Spectrum)[1][4] | 70–90 (BASF Ultrafuse TPS 90A)[3] |
| Enclosure / chamber requirement1–5 | Actively heated chamber required[10][11] | Open frame is fine[3] |
| Recommended chamber temperature°C | 60-80 actively heated (Spectrum PPS AM230)[4] | Not documented |
| Bed surface & adhesion aid | Adhesive required — Spectrum specifies Magigoo Pro HT[4] | PEI sheet or painter's tape; Polymaker warns TPU can over-stick and advises a glue stick as a release agent[12][13] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | 0.8–2.4 at the 10–30 mm/s BASF specifies on a 0.4 mm nozzle at 0.2 mm layer — the slowest material in this group[3] |
| Overall printing difficulty1–5 | Expert / industrial hardware only[10][11] | Advanced — enclosure, hardware upgrades, tuning[3] |
| Extruder requirement | Not documented | Nozzle 0.4 mm or larger; BASF caps print speed at 10–30 mm/s[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[10] | Brass fine indefinitely[14] |
| Abrasiveness1–5 | Non-abrasive when unfilled[1] | Non-abrasive[14] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 110 °C pre-dry before every print[15] | Moderate — needs dry filament and a clean nozzle; BASF caps print speed at 10–30 mm/s and Simplify3D warns that raised feed rates on flexibles most likely end in a jam[12][3] |
| Hotend requirement | Not documented | No special hot-end required, but a direct-drive extruder is (Simplify3D)[12] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Negligible (<0.1 % EMC) — Polymaker states minimal water absorption at 0.05 %[2] | Negligible (<0.1 % EMC) — BASF states drying is not necessary, unique among the elastomers here[3] |
| Equilibrium moisture content at ~50 % RH% | 0.01 in 24 h on extruded stock (ASTM D570) — effectively non-absorbing[16] | Not documented |
| Drying temperature & time | At least 3 h at 90 °C in hot dry air if the filament has taken up moisture (Spectrum)[4] | None — BASF states Ultrafuse TPS 90A arrives in a printable condition and drying is not necessary[3] |
| Symptoms when wet | Not documented | Bubbling and popping at the nozzle, stringing and a rough surface[17] |
| Effect of moisture on strength | Little to measure — equilibrium uptake is 0.05 %; 3DXTech still specifies a 110 °C, 4 h pre-dry before printing[2][15] | Not applicable — the SEBS chemistry has no amide or ester linkages to take up water, and BASF specifies no drying at all[3] |
| Storage requirement | Not documented | Sealed with desiccant; often kept in a dryer during the print[17] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 50 at break (printed XY, ISO 527, 3DXTech); 65 at break injection-moulded (ISO 527, Spectrum); 94 at yield on extruded stock (ASTM D638)[1][4][16] | Not documented |
| Young's modulusMPa | 2650 (printed XY, ISO 527, 3DXTech); 3650 injection-moulded (ISO 527, Spectrum); 5769 on extruded stock (ASTM D638)[1][4][16] | Not documented |
| Elongation at break% | 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[1][4][16] | Not documented |
| Flexural strengthMPa | 52 (printed XY, ISO 178, 3DXTech); 141 on extruded stock (ASTM D790)[1][16] | Not documented |
| Flexural modulusMPa | 2540 (printed XY, ISO 178)[1] | Not documented |
| Charpy impact, notchedkJ/m² | 1.3 notched injection-moulded (ISO 179-1eA, Spectrum); unnotched 18[4] | Not documented |
| Other impact data | Izod notched 33 J/m on extruded PPS stock, converted from 0.62 ft-lb/in (ASTM D256)[16] | Not documented |
| Brittleness1–5 | Moderate[1] | Very ductile — bends far before failing[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Rockwell 105 (and R124) on extruded PPS stock (ASTM D785)[16] | 89 Shore A and 29 Shore D (BASF Ultrafuse TPS 90A, ISO 7619-1)[3] |
| Creep resistance / sustained load1–5 | 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[16][4] | Poor — no SEBS creep test; a printed 95A TPU bar crept from 74.5 to 82.7 mm over 5 days at 1.25 kg[18] |
| Fatigue / repeated-flex resistance1–5 | Not documented | Excellent — living hinges viable[13] |
| Elasticity / flexibility1–5 | Rigid[1] | Rubbery / highly elastic[3] |
| Wear resistance & friction | Not documented | Abrasion 111 mm³ (ISO 4649) — the poorest abrasion resistance in this group, well behind TPU[3] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 90 (printed XY, ISO 75 at 0.45 MPa, 3DXTech); 129 injection-moulded (ISO 75, Spectrum); 204 on extruded stock (ASTM D648 at 66 psi)[1][4][16] | Not documented |
| HDT at 1.8 MPa°C | 107 injection-moulded (ISO 75 at 1.81 MPa, Spectrum); 104 on extruded stock (ASTM D648 at 264 psi)[4][16] | Not documented |
| Melting point / Vicat°C | 283 melting (ISO 11357, 3DXTech) and 280 on extruded stock; Vicat softening 236 at 50 N injection-moulded (ISO 306, Spectrum)[1][4][16] | 242–249 melting (BASF Ultrafuse TPS 90A, ISO 11357-3)[3] |

| Flammability / UL 94 | UL 94 V-0 at 1.5 mm, rated on the base resin[1] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Good — years with some colour shift; Polymaker lists UV exposure among the conditions TPU withstands[13] |
| Chemical resistance | Outstanding — PPS resists essentially all solvents below 200 °C[2] | Withstands industrial solvents and UV exposure (Polymaker)[13] |
| Water / humidity resistance in service1–5 | Excellent — essentially unaffected; extruded stock takes up 0.01 % water in 24 h[16] | Excellent — essentially unaffected[3] |
| Food contact | Not documented | Not food safe without specific certification (Polymaker)[13] |
| Biodegradability / compostability | Not documented | Not biodegradable[13] |
| Recyclability | Not documented | Not accepted in household plastic collection[13] |
| Health & Safety | ||
| Fume toxicity1–5 | 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[19] | Low hazard — minimal VOC and particle emission; TPU was not among the nine filaments in the chamber study[19] |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[19] | Open a window / occasional ventilation[19] |
| Post-Processing | ||
| Sanding & machining | Not documented | Difficult to sand or smooth; Polymaker limits post-processing to trimming or tumbling[13] |
| Gluing & solvent welding | Not documented | Cyanoacrylate bonds TPU; no common solvent welds it[13] |
| Vapour / chemical smoothing | Not documented | No practical vapour smoothing[13] |
| Support material pairing | Not documented | Polymaker warns TPU supports are often very difficult to remove[13] |
| Solvents & Solubility | ||
| Soluble in | None — PPS does not dissolve in any known solvent below 200 °C.[20][21] | Toluene dissolves SEBS at room temperature — Kraton quotes solution viscosity at 25 % mass in toluene, 25 °C.[22] |
| Softened or crazed by | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[21] | Soaking in hydrocarbon solvents and oils deteriorates it; short exposures are tolerated. Resists water, acids and bases.[22] |
| Solvent welding & smoothing agent | None — no solvent welds or smooths PPS.[20] | Toluene will weld it, though the joint stays soft; no workshop-safe agent, and vapour smoothing is not practical.[22] |
