Printing Parameters
Nozzle temperature°CNot documented280–310 (Bambu Lab and CHCKX); 280–320 (Siraya Tech)[2][5][15]
Bed temperature°CNot documented100–120 (Bambu Lab and CHCKX); Siraya Tech runs cooler at 70–90[2][5][15]
Enclosure / chamber requirement1–5Enclosure recommended[17]Enclosure 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[2][4][12]
Recommended chamber temperature°CNot documented50–80 (Bambu Lab); specimens were printed at a 52 °C chamber and Bambu Lab notes 70–80 °C raises Z properties[2]
Part cooling fanNot documentedBambu Lab turns the part fan on; Siraya Tech runs it off[2][5]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[17][18]Smooth or textured PEI plate with a glue stick, or a PVP glue coating[2][5]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented8–12 mm³/s at 300–320 °C (Siraya Tech)[5]
Warping tendency1–5High — enclosure needed for reliable large parts[17]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[17]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[19]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[17]Advanced — enclosure, hardware upgrades, tuning; a 320 °C hot end and a hardened nozzle are the entry requirements[2][5]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Hardened steel required — Siraya Tech and CHCKX specify hardened steel or better, Raise3D warns brass wears quickly[3][5][15]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Highly abrasive — standard CF/GF composites and glow fills[3][5]
Nozzle clog risk1–5Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-ABS, only an 80 °C pre-dry[20]Moderate — needs dry filament and a clean nozzle; Siraya Tech states nozzles below 0.4 mm will clog[5][12]
Heat-creep / jam sensitivity1–5Slightly sensitive[18]Not documented
Hotend requirementNo special hot-end required[18]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — the ABS matrix takes up 0.51–0.65 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 80 °C, 4 h pre-dry[21][22][20]High (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[2][6][23]
Equilibrium moisture content at ~50 % RH%Not documented1.30 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[2][3][4][5][24][6][23]
Drying temperature & timeNot documented100–140 °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[2][3][5]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[25]Not documented
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[25]Not documented
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[25]Sealed below 20 % RH with desiccant (Bambu Lab); Raise3D keeps the spool in a dry box throughout the print[2][3]
Mechanical Properties
Tensile strength (XY)MPa58 at break (printed XY, ISO 527) — the conductive filler raises strength above the unfilled grade's 42[1][26]95–168 (printed XY, ISO 527): Siraya Tech 95, Flashforge 108–112, Siraya Tech Core 112, Raise3D 122 conditioned and annealed, Bambu Lab and IEMAI 3D 168[2][3][4][5][24][6]

Flexural modulusMPa2275 (printed XY, ISO 178)[1]6500–9860 (printed XY, ISO 178): Flashforge 6500–7000, Siraya Tech 6800, Raise3D 8510, Siraya Tech Core 8700, Bambu Lab and IEMAI 3D 9860[2][3][4][5][24][6]
Charpy impact, notchedkJ/m²Not documented6.5 notched Charpy XY (Bambu Lab and IEMAI 3D, ISO 179); Raise3D 7.8 and Siraya Tech 11 by ISO 179 without stating notched[2][3][5][6]
Other impact dataNot documentedBambu 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[2][4][6]

Brittleness1–5Moderate[1]Brittle — snaps with little warning; 2–3 % elongation at break is typical[2][3][5]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1]Good — Flashforge cites outstanding creep resistance at high temperature and Raise3D high creep resistance, both against other nylons[3][4]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break 4 %, well below unfilled ABS[1][26]Not documented
Elasticity / flexibility1–5Rigid[1]Rigid[2]
Z strength as % of XY%Not documented34 (Bambu Lab and IEMAI 3D, Z against XY tensile, ISO 527)[2][6]
Thermal Properties
HDT at 0.45 MPa°CNot documented188–227 (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[2][3][4][5][24][6]
HDT at 1.8 MPa°CNot documented113–196 (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[2][3][5][24][6]

Continuous service temperature°CNot documented120 (Flashforge, IEC 60216, LUVOCOM PPA-CF)[4]
Annealing responseNot documentedBambu 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[2][3][5]
Flammability / UL 94Not documentedFlammable; Bambu Lab lists water, carbon oxides and nitrogen oxides as combustion products. No UL 94 rating is published for the filament grades surveyed[2]
Environment & Chemical
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[27]Better 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[2]
Water / humidity resistance in service1–5Not documentedGood — minor absorption; 1.3 % saturated moisture is roughly half what PA6-CF takes up[2][23]
Food contactNot food safe — Polymaker cites potential chemical leaching[19]Not documented
Biodegradability / compostabilityNot biodegradable[19]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[19]Not documented
Electrical & ESD propertiesSurface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ABS[1][26]Flashforge'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[4]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[28][17]Not documented
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[28]Not documented
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[28]Not documented
Hazardous species emittedStyrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[28][17]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[28][17]Not documented
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Chopped carbon fibre; dry sanding and cutting release respirable fibre-laden dust[29]
Post-Processing
Sanding & machiningSands well and takes filler before painting[19]Not documented
Painting & finishingPaints readily after light abrasion[19]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[30][17]Bambu 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[2][3]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[31][27]Formic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[32]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[31][33]Zinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[32]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[34]None — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[32]
