Densityg/cm³1.18 (ISO 1183) — above unfilled ABS at 1.05 because of the retardant loading[1][4]1.22 (Bambu Lab PLA Marble) and 1.50–1.70 (Formfutura StoneFil), ISO 1183[3][2]

Printing Parameters
Nozzle temperature°CNot documented190–230 (Bambu Lab)[3]
Bed temperature°CNot documented35–45 (Bambu Lab)[3]
Enclosure / chamber requirement1–5Enclosure recommended[15]Open frame is fine[3]
Part cooling fanNot documentedFan on[3]
Bed surface & adhesion aidClean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[15][16]Not documented
Warping tendency1–5High — enclosure needed for reliable large parts[15]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[15]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[17]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[15]Easy — minor profile tuning; 0.2 mm nozzles are not usable[18]
Extruder requirementNot documentedNozzles below 0.4 mm are not compatible (Bambu Lab)[18]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[15]Brass acceptable; hardened steel for volume work — Bambu Lab's compatibility table says no hardened nozzle is needed while the note under the same table groups PLA Marble with particle-filled materials that should always use one[18]
Abrasiveness1–5Non-abrasive[1]Moderately abrasive — stone fill[18][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[19]Moderate — needs dry filament and a clean nozzle[18]
Heat-creep / jam sensitivity1–5Slightly sensitive[16]Not documented
Hotend requirementNo special hot-end required[16]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][20][19]Moderate — 0.44 % saturated at 25 °C / 55 % RH[3]
Equilibrium moisture content at ~50 % RH%Not documented0.44 saturated at 25 °C / 55 % RH (Bambu Lab)[3]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[21]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[21]Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for this grade; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[21]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[21]Not documented
Mechanical Properties
Tensile strength (XY)MPa45 at break (printed XY, ISO 527)[1]33 ± 4 printed XY, ISO 527 (Bambu Lab)[3]
Young's modulusMPa1990 (printed XY, ISO 527)[1]2330 ± 240 printed XY, ISO 527 (Bambu Lab)[3]
Elongation at break%4 at break (printed XY, ISO 527) — well below the 10 % of unfilled 3DXTech ABS[1][22]6.7 ± 0.5 printed XY, ISO 527 (Bambu Lab)[3]
Flexural strengthMPa80 (printed XY, ISO 178)[1]75 ± 5 printed XY, ISO 178 (Bambu Lab)[3]
Flexural modulusMPa2250 (printed XY, ISO 178)[1]2920 ± 180 printed XY, ISO 178 (Bambu Lab)[3]
Charpy impact, notchedkJ/m²Not documented9.5 ± 2.6 printed XY, ISO 179, notched (Bambu Lab)[3]
Other impact dataNot documentedCharpy unnotched 24.0 printed XY (Bambu Lab, ISO 179)[3]
Layer adhesion / Z tensileMPaNot documented30 ± 4 printed Z, ISO 527 (Bambu Lab)[3]
Brittleness1–5Moderate — elongation at break falls to 4 % from 10 % for the unfilled grade[1][22]Brittle — snaps with little warning[3]
Creep resistance / sustained load1–5Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1][22]Poor — no stone-filled creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[23][24][25]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break falls to 4 % against 10 % for unfilled 3DXTech ABS[1][22]Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and the mineral filler leaves a brittle compound[26][3]
Elasticity / flexibility1–5Rigid[1]Rigid[3]
Z strength as % of XY%Not documented91 by tensile, 73 by flexural (printed, Bambu Lab)[3]
Thermal Properties
HDT at 0.45 MPa°CNot documented56 (ISO 75, 0.45 MPa)[3]
HDT at 1.8 MPa°CNot documented53 (ISO 75, 1.8 MPa)[3]
Glass transition (Tg)°C105 (DSC)[1]56 (DSC)[3]
Melting point / Vicat°CNot documented156 peak melt (DSC); Formfutura gives a 120–170 melting range for StoneFil[3][2]
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
UV resistance1–5Not documentedDegrades within weeks outdoors[27]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[28]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[17]Not documented
Biodegradability / compostabilityNot biodegradable[17]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[17]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[29][15]Low hazard — minimal VOC and particle emission[29]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[29]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[29]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[29][15]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[29][15]None needed in a normal room[29]
Dust & fibre handling hazardNot documentedFormfutura's SDS sets an occupational limit of 1 mg/m³ for the stone powder and lists it as both a fibre and a particulate — do not dry-sand without extraction[2]
Post-Processing
Sanding & machiningSands well and takes filler before painting[17]Sands to a stone-like matte surface[2]
Painting & finishingPaints readily after light abrasion[17]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[30][15]Support for PLA (Bambu Lab)[3]
Dimensional accuracy & detailNot documentedMatte mineral surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[3]
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[31][28]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[32]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[31][33]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[32][34]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[34]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[35][34]
