Printing Parameters
Nozzle temperature°CNot documented190–230 (Bambu Lab)[3]
Bed temperature°CNot documented35–45 (Bambu Lab)[3]
Enclosure / chamber requirement1–5Enclosure recommended[16]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[16][17]Not documented
Warping tendency1–5Moderate — needs adhesion aid or draught shield; the fibre reduces warping against unfilled ABS[16]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[16]Not documented
Stringing / oozing tendency1–5Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[18]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[16]Easy — minor profile tuning; 0.2 mm nozzles are not usable[19]
Extruder requirementNot documentedNozzles below 0.4 mm are not compatible (Bambu Lab)[19]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[16]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[19]
Abrasiveness1–5Highly abrasive — standard CF composite[16]Moderately abrasive — stone fill[19][2]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened nozzle of 0.4 mm minimum and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[20][21][22]Moderate — needs dry filament and a clean nozzle[19]
Heat-creep / jam sensitivity1–5Slightly sensitive[17]Not documented
Hotend requirementNo special hot-end required[17]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[23][24][20]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[25]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[25]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[25]
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity[25]Not documented
Mechanical Properties
Tensile strength (XY)MPa46 at break (printed XY, ISO 527)[1]33 ± 4 printed XY, ISO 527 (Bambu Lab)[3]
Young's modulusMPa5210 (printed XY, ISO 527) — more than double unfilled ABS[1]2330 ± 240 printed XY, ISO 527 (Bambu Lab)[3]
Elongation at break%2 at break (printed XY, ISO 527)[1]6.7 ± 0.5 printed XY, ISO 527 (Bambu Lab)[3]
Flexural strengthMPa76 (printed XY, ISO 178)[1]75 ± 5 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]
Brittleness1–5Brittle — snaps with little warning; elongation at break 2 %[1]Brittle — snaps with little warning[3]
Creep resistance / sustained load1–5Good — no creep test found; chopped carbon fibre restrains matrix flow and modulus rises to 5210 MPa against 2200–2330 for unfilled ABS[1][23][24]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[26][27][28]
Fatigue / repeated-flex resistance1–5Below average — no S-N curve found; elongation at break falls to 2 % against 10.5 % for unfilled ABS[1][23]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[29][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]
Thermal expansion (CTE)µm/m·K19–25 along the print bead and 80–84 in the build direction at 30 °C (20 wt% CF, large-format printed, TMA)[30]Not documented
Environment & Chemical
UV resistance1–5Not documentedDegrades within weeks outdoors[31]
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; dissolved by acetone[32]Not documented
Food contactNot food safe — Polymaker cites potential chemical leaching[18]Not documented
Biodegradability / compostabilityNot biodegradable[18]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[18]Not documented
Electrical & ESD propertiesSurface resistance above 10⁹ ohm/sq — not static-dissipative (ASTM D257)[1]Not documented
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[33][16]Low hazard — minimal VOC and particle emission[33]
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[33]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[33]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[33][16]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[33][16]None needed in a normal room[33]
Dust & fibre handling hazardCarbon fibre is bound in the matrix; sanding dust should not be inhaled[1]Formfutura'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[18]Sands to a stone-like matte surface[2]
Painting & finishingPaints readily after light abrasion[18]Not documented
Vapour / chemical smoothingAcetone smoothing is blunted by the fibre — only the resin fraction dissolves[32]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[34][16]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 the resin and leaves the fibre as sludge; MEK, THF, ethyl acetate and chlorinated solvents do the same.[35][32]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[36]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[35][37]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[36][38]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[38][32]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[39][38]
