Typical applicationsUnder-bonnet automotive brackets, jigs and end-use parts that must stay stiff above the 100 °C working ceiling of PA6-CF[2][3]Support that peels off by hand, avoiding the moisture handling and dissolution time that soluble supports demand[5]
Diameter tolerance± mm0.05 (Bambu Lab and Siraya Tech, 1.75 mm)[1][4]Not documented
Printing Parameters
Nozzle temperature°C280–310 (Bambu Lab and CHCKX); 280–320 (Siraya Tech)[1][4][13]220–230 (PolySupport for PLA)[5]

Enclosure / chamber requirement1–5Enclosure required (passive) — Bambu Lab specifies a 50–80 °C chamber and Siraya Tech requires an enclosure, while Flashforge states its LUVOCOM-based grade prints on machines with no heated chamber[1][3][10]Open frame is fine[5]
Recommended chamber temperature°C50–80 (Bambu Lab); specimens were printed at a 52 °C chamber and Bambu Lab notes 70–80 °C raises Z properties[1]Not documented

Bed surface & adhesion aidSmooth or textured PEI plate with a glue stick, or a PVP glue coating[1][4]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s8–12 mm³/s at 300–320 °C (Siraya Tech)[4]4–12 at Polymaker's 50–150 mm/s on a 0.4 mm nozzle at 0.2 mm layer[5]
Overall printing difficulty1–5Advanced — enclosure, hardware upgrades, tuning; a 320 °C hot end and a hardened nozzle are the entry requirements[1][4]Easy — minor profile tuning[5]
Extruder requirementNot documentedA second extruder or a tool changer[5]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required — Siraya Tech and CHCKX specify hardened steel or better, Raise3D warns brass wears quickly[2][4][13]Brass fine indefinitely[5]
Abrasiveness1–5Highly abrasive — standard CF/GF composites and glow fills[2][4]Non-abrasive[5]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; Siraya Tech states nozzles below 0.4 mm will clog[4][10]Moderate — needs dry filament and a clean nozzle; Polymaker specifies a 55 °C dry for the PLA grade and warns brass nozzle life falls to about 9 h on the PA12 grade[5][6]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5High (0.8–2 %) — 1.30 % saturated at 25 °C / 55 % RH for Bambu Lab and IEMAI 3D against 2.35 % for the same makers' PA6-CF, which is the whole reason to pay for PPA[1][7][19]Moderate — 0.64 % equilibrium water absorption (PolySupport for PLA)[5]
Equilibrium moisture content at ~50 % RH%1.30 saturated at 25 °C / 55 % RH (Bambu Lab and IEMAI 3D) against 2.35 for their PA6-CF; Siraya Tech 1.37 and 1.09 by ISO 62, Raise3D 0.6 by ISO 62 Method 1, Flashforge below 0.1 at 23 °C / 24 h[1][2][3][4][20][7][19]0.64 equilibrium water absorption (Polymaker PolySupport for PLA)[5]
Drying temperature & time100–140 °C for 8–12 h (Bambu Lab, hotter is better within that range); Siraya Tech 100 °C for 4–6 h; Raise3D 80–100 °C for 6–12 h[1][2][4]Not documented
Effect of moisture on strengthNot documentedNot a structural material; no dry-versus-conditioned data is published[21]
Storage requirementSealed below 20 % RH with desiccant (Bambu Lab); Raise3D keeps the spool in a dry box throughout the print[1][2]Not documented

Other impact dataBambu Lab and IEMAI 3D unnotched Charpy 41.7 kJ/m² XY against 4.3 in Z; Flashforge Izod 9–11 kJ/m² XY against 2.5–3 in Z[1][3][7]Not documented

Thermal Properties
HDT at 0.45 MPa°C188–227 (ISO 75 at 0.45 MPa): Raise3D 188, Flashforge 220, Bambu Lab and IEMAI 3D 227; Siraya Tech reaches 192–199 only after annealing, 84.5–97 unannealed[1][2][3][4][20][7]43 (ISO 75, 0.45 MPa, PolySupport for PA12). Polymaker's sheet prints a higher figure at the higher load, which is physically inverted; treat both HDT numbers as approximate[6]
HDT at 1.8 MPa°C113–196 (ISO 75 at 1.8 MPa): Raise3D 113, Bambu Lab and IEMAI 3D 196; Siraya Tech reaches 119–126 only after annealing, 82.5–84 unannealed[1][2][4][20][7]53 (ISO 75, 1.8 MPa, PolySupport for PA12) — printed above the 0.45 MPa figure on Polymaker's own sheet, which cannot be right; treat both as approximate[6]
Glass transition (Tg)°C80 (Siraya Tech, ASTM D3418) to 85 (Bambu Lab and IEMAI 3D, DSC)[1][4][7]Not documented
Melting point / Vicat°CMelting point 231 (Raise3D) to 258 (Bambu Lab and IEMAI 3D); Vicat softening 230–238 (ISO 306)[1][2][4][20][7]Vicat 171 (PolySupport for PA12, ISO 306)[6]
Continuous service temperature°C120 (Flashforge, IEC 60216, LUVOCOM PPA-CF)[3]Not documented
Annealing responseBambu Lab anneals at 120–140 °C for 6–12 h; Raise3D at 80–100 °C for 8 h and warns of up to 0.5 % Z shrinkage. On Siraya Tech's grades annealing lifts HDT at 0.45 MPa from 84.5 to 192 °C while notched Charpy falls from 11 to 6.3 kJ/m²[1][2][4]Not documented
Flammability / UL 94Flammable; Bambu Lab lists water, carbon oxides and nitrogen oxides as combustion products. No UL 94 rating is published for the filament grades surveyed[1]Not documented
Environment & Chemical
Chemical resistanceBetter than general nylon against weak acids, weak alkalis, most organic solvents and most oils and greases (Bambu Lab); not resistant to strong acids or strong alkalis[1]Not documented
Water / humidity resistance in service1–5Good — minor absorption; 1.3 % saturated moisture is roughly half what PA6-CF takes up[1][19]Not documented
Electrical & ESD propertiesFlashforge's data sheet gives a surface resistance of 10³ Ω or below (IEC 60093) for its LUVOCOM-based PPA-CF — the carbon loading makes it conductive rather than merely dissipative[3]Surface resistance above 10^13 ohm/sq (ASTM D257, THERMAX HTS2 and MTS1)[22][23]
Health & Safety
Fume toxicity1–5Not documentedLow hazard — minimal VOC and particle emission; none of these materials was in the chamber study[24]
Ventilation / filtration requirement1–5Not documentedOpen a window / occasional ventilation[24]
Dust & fibre handling hazardChopped carbon fibre; dry sanding and cutting release respirable fibre-laden dust[25]Not documented
Post-Processing
Support material pairingBambu Lab pairs it with Support for PA/PET; Raise3D warns that PPA-CF used as its own support bonds permanently to the model once it takes up moisture, so supports must come off before annealing[1][2]This is the support material. Polymaker publishes an adhesion matrix per model material, from very good to unusable, because break-away supports only work against the polymer they were matched to[5][6]
Solvents & Solubility
Soluble inFormic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[26]None — break-away support is removed mechanically; 3DXTech lists no water or solvent route for it.[27]
Softened or crazed byZinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[26]Not documented
Solvent welding & smoothing agentNone — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[26]None — there is no solvent to weld or smooth with.[27]
