Identity & Market
Base polymer / chemistryABS reinforced with chopped glass fibre — 3DXTech's grade is nominally 10 wt%[1][2]Break-away support compounds matched to a specific model material — Polymaker sells separate grades for PLA and for PA12[3][4]

Bed temperature°C80–100 (Bambu Lab)[2]25–60 (PolySupport for PLA)[3]
Enclosure / chamber requirement1–5Enclosure recommended — Bambu Lab specifies a 45–60 °C chamber[2][12]Open frame is fine[3]
Recommended chamber temperature°C45–60 (Bambu Lab)[2]Not documented
Part cooling fan0–80 % (Bambu Lab)[2]Not documented
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/s14 at Bambu Lab's 180 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[2][14]4–12 at Polymaker's 50–150 mm/s on a 0.4 mm nozzle at 0.2 mm layer[3]
Warping tendency1–5Moderate — needs adhesion aid or draught shield; Bambu Lab positions the fibre as reducing warping[2]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[15]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[12]Easy — minor profile tuning[3]
Extruder requirementNot documentedA second extruder or a tool changer[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[12]Brass fine indefinitely[3]
Abrasiveness1–5Highly abrasive — standard GF composite[12]Non-abrasive[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[16][17]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[3][4]
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 — 0.53 % saturated at 25 °C / 55 % RH (Bambu Lab)[2]Moderate — 0.64 % equilibrium water absorption (PolySupport for PLA)[3]
Equilibrium moisture content at ~50 % RH%0.53 saturated at 25 °C / 55 % RH (Bambu Lab)[2]0.64 equilibrium water absorption (Polymaker PolySupport for PLA)[3]
Drying temperature & time80 °C for 8 h (Bambu Lab)[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; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[18]Not a structural material; no dry-versus-conditioned data is published[18]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[18]Not documented
Mechanical Properties
Tensile strength (XY)MPa36 ± 3 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 68 at break[2][1]Not documented
Young's modulusMPa3160 ± 170 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 4210[2][1]Not documented
Elongation at break%6.3 ± 1.2 printed XY, ISO 527 (Bambu Lab); 3DXTech quotes 2 at break[2][1]Not documented
Flexural strengthMPa68 ± 4 printed XY, ISO 178 (Bambu Lab); 3DXTech quotes 70[2][1]Not documented
Flexural modulusMPa2860 ± 130 printed XY, ISO 178 (Bambu Lab); 3DXTech quotes 4420[2][1]Not documented
Charpy impact, notchedkJ/m²4.2 ± 1.1 printed XY, ISO 179, notched (Bambu Lab)[2]Not documented
Other impact dataCharpy unnotched 14.5 ± 1.5 printed XY (Bambu Lab, ISO 179)[2]Not documented
Layer adhesion / Z tensileMPa29 ± 3 printed Z, ISO 527 (Bambu Lab)[2]Not documented
Brittleness1–5Brittle — snaps with little warning; notched Charpy falls from 21.5 to 4.2 kJ/m² against unfilled Bambu Lab ABS[2][19]Not documented
Creep resistance / sustained load1–5Good — no creep test found; chopped glass fibre lifts modulus to 3160 MPa against 2200 for unfilled Bambu Lab ABS[2][19]Not documented
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; notched Charpy falls to 4.2 kJ/m² against 21.5 for unfilled Bambu Lab ABS[2][19]Not documented
Elasticity / flexibility1–5Rigid[2]Not documented
Z strength as % of XY%81 (Bambu Lab, printed Z against XY tensile)[2]Not documented
Thermal Properties
HDT at 0.45 MPa°C99 (ISO 75, 0.45 MPa, Bambu Lab) against 87 for unfilled Bambu Lab ABS[2][19]43 (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[4]
HDT at 1.8 MPa°C88 (ISO 75, 1.8 MPa, Bambu Lab) against 84 for unfilled Bambu Lab ABS[2][19]53 (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[4]
Melting point / Vicat°CNot documentedVicat 171 (PolySupport for PA12, ISO 306)[4]
Environment & Chemical
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[20]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[15]Not documented
Biodegradability / compostabilityNot biodegradable[15]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[15]Not documented
Electrical & ESD propertiesNot documentedSurface resistance above 10^13 ohm/sq (ASTM D257, THERMAX HTS2 and MTS1)[21][22]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[23][12]Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[23]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[23]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[23]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[23][12]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[23][12]Open a window / occasional ventilation[23]
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[15]Not documented
Painting & finishingPaints readily after light abrasion[15]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[24][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[3][4]
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.[25][20]None — break-away support is removed mechanically; 3DXTech lists no water or solvent route for it.[26]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[25][27]Not documented
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[28][20]None — there is no solvent to weld or smooth with.[26]
