Identity & Market
Base polymer / chemistryABS with a flame-retardant package; 3DXTech rates the base resin UL 94 V-0[1]Break-away support compounds matched to a specific model material — Polymaker sells separate grades for PLA and for PA12[2][3]
Densityg/cm³1.18 (ISO 1183) — above unfilled ABS at 1.05 because of the retardant loading[1][4]1.22 (PolySupport for PLA) and 1.29 (PolySupport for PA12), ISO 1183[2][3]
Typical priceUSD/kg1 kg-equivalent spools span 45–120; the middle of the market is about 52[5][6][7][8]1 kg-equivalent spools span 26–80; the middle of the market is about 45[9][10][11]
Price range across brandsUSD/kg45–120 across brands; SUNLU 45, YXPOLYER 50, Coex 3D 52, 3DXTech 107 at 750 g pricing; the FR PC/ABS grade runs 120[5][6][7][8]26–80 across brands and grades; IEMAI 3D E-REMOVE 26, Polymaker PolySupport for PLA 40 at 750 g, YXPOLYER 45, PolySupport for PA12 80 at 500 g[9][10][11]
Market availability1–5Niche, a handful of specialist brands[5]Available from several mainstream brands[9][5]
Spool sizes & diameters1.75 and 2.85 mm; 750 g spools[5]1.75 and 2.85 mm; 0.5 and 0.75 kg spools[9]
Typical applicationsElectrical enclosures and transport interiors that must meet a flammability rating[1]Support that peels off by hand, avoiding the moisture handling and dissolution time that soluble supports demand[2]
Printing Parameters
Nozzle temperature°CNot documented220–230 (PolySupport for PLA)[2]
Bed temperature°CNot documented25–60 (PolySupport for PLA)[2]
Enclosure / chamber requirement1–5Enclosure recommended[12]Open frame is fine[2]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[12][13]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented4–12 at Polymaker's 50–150 mm/s on a 0.4 mm nozzle at 0.2 mm layer[2]
Warping tendency1–5High — enclosure needed for reliable large parts[12]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[12]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[12]Easy — minor profile tuning[2]
Extruder requirementNot documentedA second extruder or a tool changer[2]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[12]Brass fine indefinitely[2]
Abrasiveness1–5Non-abrasive[1]Non-abrasive[2]
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]Moderate — needs dry filament and a clean nozzle; Polymaker specifies a 55 °C dry for the PLA grade and warns brass nozzle life falls to about 9 h on the PA12 grade[2][3]
Heat-creep / jam sensitivity1–5Slightly sensitive[13]Not documented
Hotend requirementNo special hot-end required[13]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[4][16][15]Moderate — 0.64 % equilibrium water absorption (PolySupport for PLA)[2]
Equilibrium moisture content at ~50 % RH%Not documented0.64 equilibrium water absorption (Polymaker PolySupport for PLA)[2]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[17]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[17]Not a structural material; no dry-versus-conditioned data is published[17]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[17]Not documented
Mechanical Properties
Tensile strength (XY)MPa45 at break (printed XY, ISO 527)[1]Not documented
Young's modulusMPa1990 (printed XY, ISO 527)[1]Not documented
Elongation at break%4 at break (printed XY, ISO 527) — well below the 10 % of unfilled 3DXTech ABS[1][18]Not documented
Flexural strengthMPa80 (printed XY, ISO 178)[1]Not documented
Flexural modulusMPa2250 (printed XY, ISO 178)[1]Not documented
Brittleness1–5Moderate — elongation at break falls to 4 % from 10 % for the unfilled grade[1][18]Not documented
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1][18]Not documented
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break falls to 4 % against 10 % for unfilled 3DXTech ABS[1][18]Not documented
Elasticity / flexibility1–5Rigid[1]Not documented
Thermal Properties
HDT at 0.45 MPa°CNot documented43 (ISO 75, 0.45 MPa, PolySupport for PA12). Polymaker's sheet prints a higher figure at the higher load, which is physically inverted; treat both HDT numbers as approximate[3]
HDT at 1.8 MPa°CNot documented53 (ISO 75, 1.8 MPa, PolySupport for PA12) — printed above the 0.45 MPa figure on Polymaker's own sheet, which cannot be right; treat both as approximate[3]
Glass transition (Tg)°C105 (DSC)[1]Not documented
Melting point / Vicat°CNot documentedVicat 171 (PolySupport for PA12, ISO 306)[3]
Flammability / UL 94UL 94 V-0 at 1.5 mm, rated on the base resin rather than the printed part[1]Not documented
Environment & Chemical
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[19]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 (ASTM D257, THERMAX HTS2 and MTS1)[20][21]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[22][12]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][12]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[22][12]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
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[23][12]This is the support material. Polymaker publishes an adhesion matrix per model material, from very good to unusable, because break-away supports only work against the polymer they were matched to[2][3]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[24][19]None — break-away support is removed mechanically; 3DXTech lists no water or solvent route for it.[25]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[24][26]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.[27]None — there is no solvent to weld or smooth with.[25]

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.
