Printing Parameters
Nozzle temperature°C250–270 (Polymaker)[1]190–230 (Bambu Lab)[4]
Bed temperature°C90–105 (Polymaker)[1]35–45 (Bambu Lab)[4]
Enclosure / chamber requirement1–5Enclosure required (passive) — Polymaker specifies a 90–100 °C chamber[1]Open frame is fine[4]
Recommended chamber temperature°C90–100 (Polymaker)[1]Not documented
Part cooling fanOff (Polymaker)[1]Fan on[4]
Bed surface & adhesion aidPEI with a glue stick or a commercial adhesive[15]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s20 at Polymaker's 250 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[1][16]Not documented
Warping tendency1–5High — enclosure needed for reliable large parts[1][17]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[15][18]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[18]Not documented
Overall printing difficulty1–5Advanced — enclosure, hardware upgrades, tuning[1][17]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 required1–4Brass fine indefinitely[17]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]
Abrasiveness1–5Non-abrasive[1]Moderately abrasive — stone fill[19][3]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a 120 °C pre-dry of 4 h or more[20]Moderate — needs dry filament and a clean nozzle[19]
Heat-creep / jam sensitivity1–5Slightly sensitive[15]Not documented
Hotend requirementAll-metal hot end required (Simplify3D)[15]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Low (0.1–0.3 %) — the PC matrix takes up 0.15–0.25 % and 3DXTech specifies a 120 °C, 4 h or more pre-dry[21][22][20]Moderate — 0.44 % saturated at 25 °C / 55 % RH[4]
Equilibrium moisture content at ~50 % RH%Not documented0.44 saturated at 25 °C / 55 % RH (Bambu Lab)[4]
Drying temperature & time75 °C for 6 h (Polymaker)[1]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[23]Not documented
Effect of moisture on strengthNo dry-versus-conditioned figures are published. Polymaker calls PC highly hygroscopic and requires a 70–80 °C dry for 6–8 h; run wet, the loss shows as surface defects and poor layer adhesion[18][23]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[23]
Storage requirementAirtight containers with desiccant to prevent reabsorption[18]Not documented
Mechanical Properties
Tensile strength (XY)MPa39.9 ± 1.0 printed XY, ISO 527 (Polymaker); 3DXTech quotes 60 at break for its FR PC/ABS[1][2]33 ± 4 printed XY, ISO 527 (Bambu Lab)[4]
Young's modulusMPa1835 ± 65 printed XY, ISO 527 (Polymaker); 3DXTech quotes 2250[1][2]2330 ± 240 printed XY, ISO 527 (Bambu Lab)[4]
Elongation at break%4.2 ± 0.3 printed XY, ISO 527 (Polymaker); 3DXTech quotes 10 at break[1][2]6.7 ± 0.5 printed XY, ISO 527 (Bambu Lab)[4]
Flexural strengthMPa66.3 ± 0.9 printed XY, ISO 178 (Polymaker); 3DXTech quotes 85[1][2]75 ± 5 printed XY, ISO 178 (Bambu Lab)[4]
Flexural modulusMPa2081 ± 106 printed XY, ISO 178 (Polymaker); 3DXTech quotes 2300[1][2]2920 ± 180 printed XY, ISO 178 (Bambu Lab)[4]
Charpy impact, notchedkJ/m²25.8 ± 1.3 printed XY, ISO 179, notched (Polymaker) — above both unfilled PC and ABS[1]9.5 ± 2.6 printed XY, ISO 179, notched (Bambu Lab)[4]
Other impact dataNotched Charpy still 13 ± 2 kJ/m² at −30 °C printed XY (Polymaker, ISO 179-1/1eA), against 1.5 in Z. Stratasys prints Izod notched at 241 J/m XZ against 34.0 J/m ZX, and unnotched 655 against 101 J/m (ASTM D256, F900 T16).[1][5]Charpy unnotched 24.0 printed XY (Bambu Lab, ISO 179)[4]
Layer adhesion / Z tensileMPa25.9-30.2 at break printed ZX (Stratasys, ASTM D638 on the F900 and Fortus 450mc); 22.9 +/- 1.2 printed Z, ISO 527 (Polymaker)[1][5]30 ± 4 printed Z, ISO 527 (Bambu Lab)[4]
Brittleness1–5Tough — absorbs impact, yields before breaking[1]Brittle — snaps with little warning[4]
Hardness (scale-specific)Shore A / Shore D / RockwellRockwell 70 (118) — the source does not name the scales and Shore D 79 on extruded unfilled PC stock (ASTM D785, D2240); no figure is published for a PC/ABS filament[24]Not documented
Creep resistance / sustained load1–5Good. Room-temperature tensile creep of moulded PC/ABS was still running unbroken at 30 MPa when the experiment was stopped for time; specimens failed within the test window at 39-47 MPa (ASTM D638)[25]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 resistance1–5Not documentedPoor — 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][4]
Elasticity / flexibility1–5Rigid[1]Rigid[4]
Z strength as % of XY%75-86 (Stratasys ZX against XZ tensile at break, ASTM D638) against 57 (Polymaker, printed Z against XY tensile)[1][5]91 by tensile, 73 by flexural (printed, Bambu Lab)[4]

Melting point / Vicat°CAmorphous — no melting point; Vicat 135 (Polymaker, ISO 306)[1]156 peak melt (DSC); Formfutura gives a 120–170 melting range for StoneFil[4][3]
Continuous service temperature°C113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[22]Not documented
Annealing response90 °C for 2 h (Polymaker)[1]Not documented
Thermal expansion (CTE)µm/m·K59.9 over -50 to 35 °C and 73.0 over -50 to 95 °C (printed XY, ASTM E831)[5]Not documented
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[18]Degrades within weeks outdoors[30]
Chemical resistanceWithstands oils, solvents and fuels; Polymaker rates it good against weak acids[18]Not documented
Food contactBisphenol-A polycarbonate is not offered as food-contact filament[18]Not documented
Biodegradability / compostabilityNot biodegradable[18]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[18]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[31]Low hazard — minimal VOC and particle emission[31]
Ultrafine-particle emission rateparticles/min≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[31]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[31][17]None needed in a normal room[31]
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[3]
Post-Processing
Sanding & machiningSands and machines well; the toughness means it cuts rather than chips[15]Sands to a stone-like matte surface[3]
Gluing & solvent weldingCyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[15]Not documented
Vapour / chemical smoothingAcetone attacks the ABS phase, so surface smoothing is partial rather than full[1]Not documented
Support material pairingPrints its own supports; 3DXTech sells a dedicated PC break-away support[15]Support for PLA (Bambu Lab)[4]
Dimensional accuracy & detailNot documentedMatte mineral surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[4]
Solvents & Solubility
Soluble inDichloromethane and chloroform dissolve the PC phase; acetone, MEK and THF dissolve the ABS phase.[32][33]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[34]
Softened or crazed byPetrol, esters, ether and 1 % alkali stress-crack the PC phase; aromatics and esters soften the ABS phase.[32][33]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[34][35]
Solvent welding & smoothing agentAcetone attacks only the ABS phase, so smoothing is partial; a dichloromethane cement welds the whole section.[1][36]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[37][35]
