Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[13]Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[14]
Abrasiveness1–5Highly abrasive — standard GF composite[13]Non-abrasive when unfilled[3]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher for the glass-filled grade[19][20]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry before every print[21]

Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell M110 / R126 on extruded PEI stock (ASTM D785)[24]

Thermal expansion (CTE)µm/m·KNot documented44.9 (printed XY, -50 to 80 °C, ASTM E831), falling to 31.4 over 80-160 °C; ZX gives 44.5 over -50 to 60 °C. Black pigment raises it to 51.9[4]

Environment & Chemical
UV resistance1–5Not documentedGood — years with some colour shift. 1000 h of QUV cycling to ASTM G154 left printed ZX coupons at 55.5 MPa yield against 56.0 unexposed, with elongation and modulus unchanged[4]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[26]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[18]Not documented
Biodegradability / compostabilityNot biodegradable[18]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[18]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[27][13]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[27]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[27]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[27]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[27][13]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[27][13]Ventilated room or enclosure recommended[27]
Dust & fibre handling hazardGlass fibre is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[18]Not documented
Painting & finishingPaints readily after light abrasion[18]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[28][13]Not documented
Dimensional accuracy & detailBambu Lab describes a smooth matte finish with micro-spot gloss that blurs layer lines[2]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.[29][26]Chlorinated hydrocarbons — dichloromethane and chloroform — are solvents for polyetherimide. Laboratory reagents.[30][29]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[29][31]Acetone, MEK, benzene, toluene and butyl acetate craze or stress-crack it; alcohols, fuels and dilute acids do not.[29][30]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[32][26]Dichloromethane is the only welding route, and it is a controlled carcinogen rather than a workshop material.[30][29]
