Typical applicationsLarge enclosure and automotive parts where plain ABS warps or softens too early[1][2]Support for PEEK, PEI and PC-class prints, where PVA and PLA-based supports would decompose[4][5]
Printing Parameters
Nozzle temperature°C270–290 (ABS Pro); 270–300 (ABS Max) — 25–35 °C above plain ABS[1][2]Not documented
Bed temperature°C120 (ABS Max)[2]Not documented
Enclosure / chamber requirement1–5Enclosure required (passive)[1][2][11]Actively heated chamber required — it is used inside high-temperature builds[4]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[11][12]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/sUp to 250 mm/s (ABS Pro) and 200 mm/s (ABS Max), equivalent to 20 and 16 on a 0.4 mm nozzle at 0.2 mm layer[1][2][13]Not documented
Warping tendency1–5High — enclosure needed for reliable large parts[11]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[11]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[14]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; the hotter nozzle rules out PTFE-lined hotends[1][2]Expert / industrial hardware only[4]
Extruder requirementNot documentedA dual-extruder machine rated for high-temperature materials; 3DXTech states the grade is intended for dual-extruder printers designed to print high-temp materials[15]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[11]Brass fine indefinitely[4]
Abrasiveness1–5Non-abrasive[11]Non-abrasive[4]
Nozzle clog risk1–5Low — unfilled ABS compound; no special hot-end required and clogging is not among the listed drawbacks[12][16]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry for HTS1 and 80 °C for MTS1[15][17]
Heat-creep / jam sensitivity1–5Slightly sensitive[12]Not documented
Hotend requirementNo special hot-end required[12]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.51 % maximum water absorption (ABS Pro)[1]Not documented
Equilibrium moisture content at ~50 % RH%0.51 maximum water absorption (Polymaker ABS Pro)[1]Not documented
Drying temperature & time70 °C for 6 h (ABS Max)[2]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[18]Not documented
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures[18]No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry for HTS1 and 80 °C for MTS1 because trapped water flashes to steam at these nozzle temperatures[15][17]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[18]Not documented

Elasticity / flexibility1–5Rigid[1]Not documented
Z strength as % of XY%63 (ABS Pro) and 71 (ABS Max), printed[1][2]Not documented
Wear resistance & frictionNot documented3DXTech marks tensile strength, modulus and elongation as not applicable for its support grades — they are not characterised as structural materials[4]
Thermal Properties
HDT at 0.45 MPa°C106.4 (ABS Pro) and 118.1 (ABS Max), ISO 75 at 0.45 MPa[1][2]Not documented

Environment & Chemical
UV resistance1–5Months outdoors before embrittlement[14]Not documented
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[3]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[14]Not documented
Biodegradability / compostabilityNot biodegradable[14]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[14]Not documented
Electrical & ESD propertiesNot documentedSurface resistance above 10^13 ohm/sq on all three THERMAX support grades (ASTM D257) — insulating[4][21][5]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[22][11]Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[22]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[22]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[22]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[22][11]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[22][11]Open a window / occasional ventilation[22]
Post-Processing
Sanding & machiningSands well and takes filler before painting[14]Not documented
Painting & finishingPaints readily after light abrasion[14]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works[3]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[23][11]This is the support material. MTS1 is matched to PC/ABS and PC; HTS1 and HTS2 to the higher-temperature classes[5][4]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[24][3]Aqueous alkali, not water: IEMAI specifies an alkaline bath in an ultrasonic cleaner until the support dissolves.[10]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[24][25]Not documented
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]None — the alkaline bath dissolves the support rather than welding anything.[10]

Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
