Printing Parameters
Nozzle temperature°C260–290 (Bambu Lab)[1]Not documented
Enclosure / chamber requirement1–5Enclosure required (passive) — Bambu Lab specifies a 45–60 °C chamber[1]Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[3]
Recommended chamber temperature°C45–60 (Bambu Lab)[1]Not documented
Bed surface & adhesion aidPEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[9][10]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s8 at Bambu Lab's 100 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[1][11]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[9]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed[10]Not documented
Overall printing difficulty1–5Expert / industrial hardware only[1][12]Expert / industrial hardware only[3]
Extruder requirement0.6 mm nozzle recommended by Bambu Lab; 0.4 and 0.8 also supported[1]Not documented
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — Polymaker measures brass nozzle life at about 9 h on PA612-CF15 and recommends hardened steel or ruby[2]Hardened steel required[3]
Abrasiveness1–5Highly abrasive — standard CF composite; Polymaker puts brass nozzle life at roughly 9 h on PA612-CF15[2]Highly abrasive — standard CF composite[3]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles[12]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[13][14]
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 %) — 0.88 % saturated at 25 °C / 55 % RH for Bambu Lab PAHT-CF, a third of its PA6-CF; Polymaker's PA612-CF15 reaches 2.2 % equilibrium[1][2][15]Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[3][4]
Equilibrium moisture content at ~50 % RH%0.88 saturated at 25 °C / 55 % RH (Bambu Lab PAHT-CF); 2.2 equilibrium (Polymaker PA612-CF15)[1][2]0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[3][4]
Drying temperature & time80 °C for 8–12 h (Bambu Lab)[1]Not documented
Effect of moisture on strengthPolymaker publishes dry and wet printed blocks for PA612-CF15 itself: at 2.57 % moisture tensile falls only 91.9 → 83.1 MPa and modulus 5137 → 3991 MPa — the PA612 backbone absorbs far less than PA6[2][16]No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[3]
Storage requirementSealed below 20 % RH with desiccant[12]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[17][18]Not documented
Mechanical Properties
Tensile strength (XY)MPa92 ± 7 (Bambu Lab) and 91.9 ± 2.0 (Polymaker PA612-CF15, dry/annealed) printed XY, ISO 527; the Polymaker grade only falls to 83.1 ± 2.2 conditioned to 2.57 % moisture[1][2]59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[3][4]
Young's modulusMPa3860 ± 230 (Bambu Lab) and 5137 ± 192 (Polymaker PA612-CF15, dry) printed XY, ISO 527; Polymaker 3991 ± 137 conditioned[1][2]5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[3][4]
Elongation at break%2.6 ± 0.2 dry (Polymaker PA612-CF15) to 8.4 ± 1.8 (Bambu Lab) printed XY, ISO 527; Polymaker 4.1 ± 0.3 conditioned[1][2]1.4 ± 0.1 (PPS-CF10) and 2.0 ± 0.2 (PPS-GF20) printed XY, ISO 527 — the lowest elongation in the dataset[3][4]
Flexural modulusMPa4230 ± 210 printed XY, ISO 178 (Bambu Lab)[1]Not documented
Charpy impact, notchedkJ/m²8.1 ± 0.8 printed XY dry and 7.7 ± 0.5 conditioned, ISO 179 notched (Polymaker PA612-CF15)[2]5.3 ± 0.2 printed XY for PPS-CF10 and 7.3 ± 0.2 for PPS-GF20, ISO 179 notched[3][4]
Other impact dataCharpy unnotched 57.5 ± 3.4 and notched 22.8 ± 1.8 printed XY (Bambu Lab, ISO 179)[1]Not documented
Layer adhesion / Z tensileMPa47 ± 5 (Bambu Lab) and 48.3 ± 3.9 (Polymaker PA612-CF15, dry) printed Z, ISO 527; Polymaker 35.6 ± 3.0 conditioned[1][2]32.0 ± 5.1 (PPS-CF10) and 22.9 ± 0.8 (PPS-GF20) printed Z, ISO 527[3][4]
Brittleness1–5Moderate[1]Very brittle — cracks or shatters easily; elongation at break 1.4 %[3]
Hardness (scale-specific)Shore A / Shore D / RockwellRockwell M88 / R117 on extruded PA66-GF30 stock (ASTM D785); no figure is published for a carbon-fibre long-chain nylon filament[19]Rockwell 105 (and R124) on extruded unfilled PPS stock (ASTM D785); no figure is published for a fibre-filled PPS filament[20]
Creep resistance / sustained load1–5Good. Ensinger rates its PA66-CF30 compound for sustained static and dynamic load with 110 °C continuous service; the long-chain PA612 matrix takes up 0.88 % at saturation, a third of the same maker's PA6-CF, so it holds dimension better[21][2]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[20][22][3]
Fatigue / repeated-flex resistance1–5Good. Ensinger states carbon-filled PA66 compounds have improved fatigue strength in tension, flexure and compression[21]Not documented

Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[23]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[23]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[23]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[23]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament[23]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[23]Ventilated room or enclosure recommended[23]
Dust & fibre handling hazardFibre is bound in the matrix; sanding dust should not be inhaled[17]Fibre is bound in the matrix; sanding dust should not be inhaled[3]
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.[24]None — PPS does not dissolve in any known solvent below 200 °C.[25][26]
Softened or crazed byZinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[24]Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[26]
Solvent welding & smoothing agentNone — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[24]None — no solvent welds or smooths PPS.[25]
