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[15]Low — no special hot-end required, no drybox and no hardened nozzle, and 3DXTech states drying is not needed[11][16][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][17][15]Low (0.1–0.3 %) — Simplify3D lists water resistance as a headline property[11]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[18]Bubbling and popping at the nozzle, stringing and a rough surface[18]
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[18]Polymaker 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[18]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[18]Sealed with desiccant; less critical than for the polyamides[18]
Mechanical Properties
Tensile strength (XY)MPa45 at break (printed XY, ISO 527)[1]40 at break (printed XY, ISO 527)[2]
Young's modulusMPa1990 (printed XY, ISO 527)[1]1350 (printed XY, ISO 527) — the lowest modulus of the styrenics here[2]
Elongation at break%4 at break (printed XY, ISO 527) — well below the 10 % of unfilled 3DXTech ABS[1][19]18 at break (printed XY, ISO 527)[2]

Brittleness1–5Moderate — elongation at break falls to 4 % from 10 % for the unfilled grade[1][19]Tough — absorbs impact, yields before breaking[2]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1][19]Moderate — no printed-HIPS creep test found; Tg of 100 °C keeps room-temperature service far below softening[2][11]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break falls to 4 % against 10 % for unfilled 3DXTech ABS[1][19]Moderate[2]

Flammability / UL 94UL 94 V-0 at 1.5 mm, rated on the base resin rather than the printed part[1]Flammable; no UL 94 rating published[2]
Environment & Chemical
UV resistance1–5Not documentedMonths outdoors before embrittlement — polystyrene yellows and chalks under UV[14]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[20]Dissolves completely in d-limonene — the basis of its use as a soluble support[3]

RecyclabilityMechanically recyclable but not accepted in household plastic collection[14]Not accepted in household plastic collection[14]
Electrical & ESD propertiesNot documentedSurface resistance above 10¹³ ohm/sq — insulating (ASTM D257)[2]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[21][12]High — hazardous VOC such as styrene; enclosure and filtration needed[21]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[21]12–113 styrene, the range measured across ABS and the one HIPS filament tested[21]
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[21]≈4 × 10⁹ median for the HIPS filament tested, an order of magnitude below ABS but forty times PLA[21]
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[21][12]Styrene was the only dominant VOC identified for the HIPS filament tested[21]
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[21][12]Enclosure with carbon and HEPA filtration[21]
Post-Processing
Sanding & machiningSands well and takes filler before painting[14]Sands and paints readily, like ABS[14]
Painting & finishingPaints readily after light abrasion[14]Not documented
Gluing & solvent weldingNot documentedSolvent-welds with d-limonene, and with acetone via its polystyrene backbone[11][3]
Vapour / chemical smoothingNot documentedd-limonene attacks the surface; acetone smoothing is far less effective than on ABS[3][11]
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[11][12]Used as the support material itself — dissolves in d-limonene, or breaks away from ABS and ASA[3]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[22][20]d-limonene, 12–24 h submerged with occasional agitation; acetone also dissolves it, and xylene does so at 23 °C.[23][22][24]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[22][25]Limonene also disrupts layer adhesion in some ABS and ASA grades, so an ABS model can flake apart in the same bath.[25]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[26]Limonene welds and lightly etches it; acetone welds through the polystyrene backbone but smooths less well than ABS.[23][25]
