Identity & Market
Base polymer / chemistryCarbon-fibre reinforced PPS — Polymaker's Fiberon grade is nominally 10 wt%[1]Break-away support compounded to survive high-temperature print chambers; 3DXTech sells separate grades for PC/ABS and for the PAEK and PEI class[2][3]
Densityg/cm³1.29 (Fiberon PPS-CF10) and 1.36 (Fiberon PPS-GF20), ISO 1183[1][4]1.37 (3DXTech THERMAX HTS1, ISO 1183)[2]
Typical priceUSD/kg1 kg-equivalent spools span 93–174; the middle of the market is about 140[5][6][7][8]1 kg-equivalent spools cluster near 168[9]
Price range across brandsUSD/kg93-174 across brands and formats; Polymaker Fiberon PPS-GF20 93 at 3 kg, IEMAI 3D CF-PPS 131 at 750 g, LEHVOSS Luvocom 3F PPS CF 9938 164 at 2.3 kg, Bambu Lab PPS-CF 174 at 750 g[5][6][7][8]100–290 across grades; 3DXTech THERMAX MTS1 100 at 2 kg, HTS2 168 at 250 g, HTS1 250 at 500 g, IEMAI 3D HT-SP 290 at 1 kg[9][10]
Market availability1–5Available from several mainstream brands[5][6][7]Niche, a handful of specialist brands[9][10]
Spool sizes & diameters1.75 mm; 0.5 kg spools[5]1.75 mm; 250 g, 500 g, 1 kg and 2 kg spools[9]
Typical applicationsChemical and automotive parts needing PPS chemistry with structural stiffness[1]Support for PEEK, PEI and PC-class prints, where PVA and PLA-based supports would decompose[2][3]
Printing Parameters
Enclosure / chamber requirement1–5Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[1]Actively heated chamber required — it is used inside high-temperature builds[2]
Overall printing difficulty1–5Expert / industrial hardware only[1]Expert / industrial hardware only[2]
Extruder requirementNot documentedA dual-extruder machine rated for high-temperature materials; 3DXTech states the grade is intended for dual-extruder printers designed to print high-temp materials[11]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Brass fine indefinitely[2]
Abrasiveness1–5Highly abrasive — standard CF composite[1]Non-abrasive[2]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles; Polymaker specifies hardened steel or ruby nozzles for carbon-filled PPS and Prusa lists composites as a higher clogging risk[12][13]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry for HTS1 and 80 °C for MTS1[11][14]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[1][4]Not documented
Equilibrium moisture content at ~50 % RH%0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[1][4]Not documented
Effect of moisture on strengthNo dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[1]No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry for HTS1 and 80 °C for MTS1 because trapped water flashes to steam at these nozzle temperatures[11][14]
Mechanical Properties
Tensile strength (XY)MPa59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[1][4]Not documented
Young's modulusMPa5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[1][4]Not documented
Elongation at break%1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[1][4]Not documented
Charpy impact, notchedkJ/m²5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[1][4]Not documented
Layer adhesion / Z tensileMPa32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[1][4]Not documented
Brittleness1–5Very brittle — cracks or shatters easily; elongation at break 1.4 %[1]Not documented
Hardness (scale-specific)Shore A / Shore D / RockwellRockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[15]Not documented
Creep resistance / sustained load1–5Excellent — holds load for years. Ensinger lists high creep resistance for unfilled PPS stock and Spectrum states creep resistance is unchanged under continuous load at high temperature; the fibre raises heat deflection to 252 °C at 0.45 MPa[15][16][1]Not documented
Elasticity / flexibility1–5Rigid[1]Not documented
Z strength as % of XY%54 (PPS-CF10) and 36 (PPS-GF20), printed[1][4]Not documented
Wear resistance & frictionNot documented3DXTech marks tensile strength, modulus and elongation as not applicable for its support grades — they are not characterised as structural materials[2]
Thermal Properties
HDT at 0.45 MPa°C252.5 (PPS-CF10) and 236.3 (PPS-GF20), printed, ISO 75 at 0.45 MPa[1][4]Not documented
HDT at 1.8 MPa°C133 (PPS-CF10) and 125.8 (PPS-GF20), printed, ISO 75 at 1.8 MPa[1][4]205 (THERMAX HTS1, printed XY, ISO 75 at 1.8 MPa)[2]
Glass transition (Tg)°C97.7 (PPS-CF10) and 95.0 (PPS-GF20), DSC[1][4]225 (3DXTech THERMAX HTS1, DSC) — high enough to stay solid inside a PEI or PEEK build[2]
Melting point / Vicat°C279.7 (PPS-CF10) and 279.6 (PPS-GF20) melting, DSC; Vicat 267.5 and 272.5 (ISO 306)[1][4]Not documented
Continuous service temperature°C170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[15]Not documented
Environment & Chemical
Chemical resistanceOutstanding — PPS resists essentially all solvents below 200 °C[12]Not documented
Electrical & ESD propertiesSurface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[1][4]Surface resistance above 10^13 ohm/sq on all three THERMAX support grades (ASTM D257) — insulating[2][17][3]
Health & Safety
Fume toxicity1–5Moderate — 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[18]Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[18]
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[18]Open a window / occasional ventilation[18]
Dust & fibre handling hazardFibre is bound in the matrix; sanding dust should not be inhaled[1]Not documented
Post-Processing
Support material pairingNot documentedThis is the support material. MTS1 is matched to PC/ABS and PC; HTS1 and HTS2 to the higher-temperature classes[3][2]
Solvents & Solubility
Soluble inNone — PPS does not dissolve in any known solvent below 200 °C.[19][20]Aqueous alkali, not water: IEMAI specifies an alkaline bath in an ultrasonic cleaner until the support dissolves.[10]
Softened or crazed byNothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[20]Not documented
Solvent welding & smoothing agentNone — no solvent welds or smooths PPS.[19]None — the alkaline bath dissolves the support rather than welding anything.[10]
