Printing Parameters
Nozzle temperature°CNot documented410 ± 10 (Prusament) — the hottest nozzle in the dataset[3]
Bed temperature°CNot documented140–160 (Prusament); 130–140 (3DXTech)[3][2]
Enclosure / chamber requirement1–5Enclosure recommended[15]Actively heated chamber required — Prusa specifies 90 °C[3]
Recommended chamber temperature°CNot documented90 (Prusament)[3]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[15][16]PA nylon sheet or powder-coated sheet with high-temperature glue (Prusament)[3]
Warping tendency1–5Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ABS[15]Severe — heated chamber needed[3]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[15]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[17]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[15]Expert / industrial hardware only[3][18]
Extruder requirementNot documentedA hot end rated to 420 °C, a heated chamber and a high-temperature bed; Prusa dries the filament at 150 °C for 6–8 h before printing[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[15]Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[3]
Abrasiveness1–5Highly abrasive — standard CF composite[15]Non-abrasive when unfilled[2]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened nozzle of 0.4 mm minimum and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[19][20][21]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 150 °C pre-dry before every print[22]
Heat-creep / jam sensitivity1–5Slightly sensitive[16]Not documented
Hotend requirementNo special hot-end required[16]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[23][24][19]Not documented
Equilibrium moisture content at ~50 % RH%Not documented0.4 in 24 h and 0.7 in 7 days at 24 °C and 22 % RH (Prusament)[3]
Drying temperature & timeNot documented150 °C for 6–8 h (Prusament) — the hottest drying schedule in the dataset[3]
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]No dry-versus-conditioned figures are published; 3DXTech mandates a 150 °C, 4 h pre-dry before every print because trapped water flashes to steam at these nozzle temperatures[22]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[25]Not documented

Environment & Chemical
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[28]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[17]Not documented
Biodegradability / compostabilityNot biodegradable[17]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[17]Not documented
Electrical & ESD propertiesSurface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[29][15]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[29]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[29]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[29]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[29][15]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[29][15]Ventilated room or enclosure recommended[29]
Dust & fibre handling hazardCarbon fibre is bound in the matrix; sanding dust should not be inhaled[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[17]Not documented
Painting & finishingPaints readily after light abrasion[17]Not documented
Vapour / chemical smoothingAcetone smoothing is blunted by the fibre — only the resin fraction dissolves[28]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[30][15]Not documented
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[31][28]Chlorinated hydrocarbons — dichloromethane and chloroform — are solvents for polyetherimide. Laboratory reagents.[32][31]
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]Acetone, MEK, benzene, toluene and butyl acetate craze or stress-crack it; alcohols, fuels and dilute acids do not.[31][32]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[34][28]Dichloromethane is the only welding route, and it is a controlled carcinogen rather than a workshop material.[32][31]
