Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[18]Hardened steel required[20][3]
Abrasiveness1–5Non-abrasive[1]Highly abrasive — standard CF composite[20][23]
Nozzle clog risk1–5Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its FR-ABS, only an 80 °C pre-dry[24]Moderate — needs dry filament and a clean nozzle[20]

Hotend requirementNo special hot-end required[19]Hardened steel nozzle; Bambu Lab lists PLA-CF among the filaments its hardened-steel nozzle exists for[23][20]
Other hardware wearNot documentedBambu Lab reports AMS wear; Polymaker advises against running PLA-CF through an AMS at all[20][3]
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[4][25][24]Moderate — 0.42 % saturated at 25 °C / 55 % RH (Bambu Lab); 0.38 % equilibrium (Polymaker)[5][3]

Hardness (scale-specific)Shore A / Shore D / RockwellNot documented71.5 Shore D measured on printed bars for Sunlu CF PLA (My Tech Fun), against 75.3 for the same maker's unfilled PLA[28]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1][27]Poor — 12 mm bars sagged to 15.1, 19.8 and 21.3 mm over 5 days at 1.25 kg across three brands, against 16.2–21.8 mm for their unfilled PLA[29][30][28]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break falls to 4 % against 10 % for unfilled 3DXTech ABS[1][27]Poor — no CF-grade S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and elongation in Z falls to 0.9 %[31][3]

Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors[32]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[33]Good against weak acids, oils and grease; poor against strong acids and alkalis[3]
Food contactNot food safe — Polymaker cites potential chemical leaching[22]Not documented
Biodegradability / compostabilityNot biodegradable[22]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[22]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[34][18]Low hazard — minimal VOC and particle emission[34]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[34]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[34]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[34][18]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[34][18]None needed in a normal room[34]
Dust & fibre handling hazardNot documentedCarbon fibre is bound in the matrix; sanding dust should not be inhaled[2]
Post-Processing
Sanding & machiningSands well and takes filler before painting[22]Not documented
Painting & finishingPaints readily after light abrasion[22]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[35][18]Support for PLA (Bambu Lab); PolySupport and PolyDissolve S1 (Polymaker)[5][3]
Dimensional accuracy & detailNot documentedMatte finish hides layer lines; stiffness is the gain — tensile strength stays at or below Bambu Lab PLA Basic's 35 MPa and Polymaker PolyLite PLA's 52.3 MPa[5][3][36][37]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[38][33]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[39]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[38][40]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[39][41]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[41]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[42][41]
