Printing Parameters
Enclosure / chamber requirement1–5Enclosure required (passive)[8]Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[2]
Bed surface & adhesion aidPEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[9][8]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[9]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed[8]Not documented
Overall printing difficulty1–5Expert / industrial hardware only[8][10]Expert / industrial hardware only[2]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — Polymaker measures brass nozzle life at about 9 h on PA612-ESD and recommends hardened steel or ruby[1]Hardened steel required[2]
Abrasiveness1–5Highly abrasive — carbon-filled nylon composite; Polymaker puts brass nozzle life at roughly 9 h on PA612-ESD[1]Highly abrasive — standard CF composite[2]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles[10]High — 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[11][12]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed[9]Not documented
Hotend requirementMay require an all-metal hot end (Simplify3D)[9]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5High (0.8–2 %) — the PA612 matrix sits between PA6 and PA12[13][14]Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[2][3]
Equilibrium moisture content at ~50 % RH%Not documented0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[2][3]
Effect of moisture on strengthPolymaker publishes dry and wet printed blocks for PA612-ESD itself: at 4.64 % moisture tensile falls 84.3 → 73.6 MPa and modulus 4294 → 3731 MPa[1][14]No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[2]
Storage requirementSealed below 20 % RH with desiccant[10]Not documented
Hydrolysis at melt temperaturePolymaker specifies an 80–100 °C dry and storage below 20 % RH; no molecular-weight loss figure is published, and the wet data it does publish is conditioning rather than melt hydrolysis[15][16]Not documented
Mechanical Properties
Tensile strength (XY)MPa84.3 ± 2.3 printed XY dry (annealed 100 °C/16 h), 73.6 ± 2.3 conditioned to 4.64 % moisture, ISO 527[1]59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[2][3]
Young's modulusMPa4293.7 ± 116.4 printed XY dry and 3730.8 ± 156.2 conditioned, ISO 527[1]5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[2][3]
Elongation at break%3.0 ± 0.1 printed XY dry and 4.2 ± 0.4 conditioned, ISO 527[1]1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[2][3]
Charpy impact, notchedkJ/m²5.9 ± 0.4 printed XY dry and 4.9 ± 0.3 conditioned, ISO 179 notched[1]5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[2][3]
Other impact dataCharpy unnotched 24.1 ± 2.4 printed XY and 4.5 ± 0.2 printed Z (ISO 179)[1]Not documented
Layer adhesion / Z tensileMPa21.5 ± 2.7 printed Z dry — only a quarter of XY, the most anisotropic nylon composite here; 19.2 ± 1.6 conditioned[1]32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[2][3]
Brittleness1–5Brittle — snaps with little warning; elongation 3.0 % in XY and 1.4 % in Z[1]Very brittle — cracks or shatters easily; elongation at break 1.4 %[2]
Hardness (scale-specific)Shore A / Shore D / RockwellRockwell M88 / R117 on extruded PA66-GF30 stock (ASTM D785); no figure is published for a conductive carbon-filled nylon filament[17]Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[18]
Creep resistance / sustained load1–5Good. Ensinger rates its PA66-CF30 compound for sustained static and dynamic load at 110 °C continuous service; the PA612 matrix here still takes up 4.64 % moisture at conditioning, which softens it[19][1]Excellent — 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[18][20][2]
Fatigue / repeated-flex resistance1–5Good. Ensinger states carbon-filled PA66 compounds have improved fatigue strength in tension, flexure and compression[19]Not documented
Elasticity / flexibility1–5Rigid[1]Rigid[2]
Z strength as % of XY%26 (printed Z against XY tensile)[1]54 (PPS-CF10) and 36 (PPS-GF20), printed[2][3]

Continuous service temperature°CNot documented170 long-term service on extruded PPS stock, converted from 338 °F; no figure published for the carbon-filled grade[18]
Flammability / UL 94Flammable; no UL 94 rating published for the grades surveyed[15]Not documented
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement — unstabilised polyamide yellows under UV[8]Not documented
Chemical resistanceWithstands oils, fuels and alkalis[8]Outstanding — PPS resists essentially all solvents below 200 °C[11]
Food contactNot food-contact certified as filament[8]Not documented
Biodegradability / compostabilityNot biodegradable[8]Not documented
RecyclabilityNot accepted in household plastic collection[8]Not documented
Electrical & ESD propertiesStatic-dissipative — the reason the grade exists; Polymaker's insulating nylon composites sit above 10¹² ohm by contrast[1][13]Surface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[2][3]
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[21]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[21]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[21]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[21]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament[21]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[21]Ventilated room or enclosure recommended[21]
Dust & fibre handling hazardFibre is bound in the matrix; sanding dust should not be inhaled[15]Fibre is bound in the matrix; sanding dust should not be inhaled[2]
Post-Processing
Sanding & machiningSands poorly — gums rather than powders[9]Not documented
Gluing & solvent weldingCyanoacrylate; no common solvent welds polyamide[9]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[9]Not documented
Solvents & Solubility
Soluble inFormic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[22]None — PPS does not dissolve in any known solvent below 200 °C.[23][24]
Softened or crazed byZinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[22]Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[24]
Solvent welding & smoothing agentNone — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[22]None — no solvent welds or smooths PPS.[23]
