| Enclosure / chamber requirement1–5 | Not documented | Open frame is fine[3] |
| Part cooling fan | 10–50% fan recommended; mechanical-test specimens used 50–100%.[1] | Fan on[3] |
| Bed surface & adhesion aid | PEI build plate[1] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 9 mm³/s maximum in eSUN spiral-vase test; mechanical specimens used 2 mm³/s. Linear recommendation 25–110 mm/s is a separate quantity.[1] | Not documented |
| Overall printing difficulty1–5 | Not documented | Easy — minor profile tuning; 0.2 mm nozzles are not usable[11] |
| Extruder requirement | Not documented | Nozzles below 0.4 mm are not compatible (Bambu Lab)[11] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Not documented | 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[11] |
| Abrasiveness1–5 | Not documented | Moderately abrasive — stone fill[11][2] |
| Nozzle clog risk1–5 | Not documented | Moderate — needs dry filament and a clean nozzle[11] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Not documented | Moderate — 0.44 % saturated at 25 °C / 55 % RH[3] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.44 saturated at 25 °C / 55 % RH (Bambu Lab)[3] |
| Drying temperature & time | 70–75 °C for 6–8 h; re-dry after receiving or extended exposure.[1] | Not documented |
| Effect of moisture on strength | Not documented | 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[12] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | >16.5 MPa printed XY, GB/T 1040; manufacturer lower bound, not an exact measurement.[1] | 33 ± 4 printed XY, ISO 527 (Bambu Lab)[3] |
| Young's modulusMPa | Not documented | 2330 ± 240 printed XY, ISO 527 (Bambu Lab)[3] |
| Elongation at break% | >520% printed XY, GB/T 1040; manufacturer lower bound.[1] | 6.7 ± 0.5 printed XY, ISO 527 (Bambu Lab)[3] |
| Flexural strengthMPa | Not documented | 75 ± 5 printed XY, ISO 178 (Bambu Lab)[3] |

| Charpy impact, notchedkJ/m² | Not documented | 9.5 ± 2.6 printed XY, ISO 179, notched (Bambu Lab)[3] |
| Other impact data | Not documented | Charpy unnotched 24.0 printed XY (Bambu Lab, ISO 179)[3] |
| Layer adhesion / Z tensileMPa | 7.5 MPa printed Z, GB/T 1040 (manufacturer test)[1] | 30 ± 4 printed Z, ISO 527 (Bambu Lab)[3] |
| Brittleness1–5 | Not documented | Brittle — snaps with little warning[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | 90 Shore A nominal grade designation; do not compare numerically with Shore D or Rockwell.[10] | Not documented |
| Creep resistance / sustained load1–5 | Not documented | 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[13][14][15] |
| Fatigue / repeated-flex resistance1–5 | Not documented | 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[16][3] |
| Elasticity / flexibility1–5 | Not documented | Rigid[3] |
| Z strength as % of XY% | Not documented | 91 by tensile, 73 by flexural (printed, Bambu Lab)[3] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 56 (ISO 75, 0.45 MPa)[3] |
| HDT at 1.8 MPa°C | Not documented | 53 (ISO 75, 1.8 MPa)[3] |
| Glass transition (Tg)°C | Not documented | 56 (DSC)[3] |
| Melting point / Vicat°C | 110 °C Vicat softening (GB/T 1633, 120 °C/h, 10 N); not HDT or a continuous-use rating.[1] | 156 peak melt (DSC); Formfutura gives a 120–170 melting range for StoneFil[3][2] |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Degrades within weeks outdoors[17] |
| Health & Safety | ||
| Fume toxicity1–5 | Not documented | Low hazard — minimal VOC and particle emission[18] |
| Ventilation / filtration requirement1–5 | Not documented | None needed in a normal room[18] |
| Dust & fibre handling hazard | Not documented | 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 & machining | Not documented | Sands to a stone-like matte surface[2] |
| Support material pairing | Not documented | Support for PLA (Bambu Lab)[3] |
| Dimensional accuracy & detail | Not documented | Matte mineral surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[3] |
| Solvents & Solubility | ||
| Soluble in | Not documented | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[19] |
| Softened or crazed by | Not documented | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[19][20] |
| Solvent welding & smoothing agent | Not documented | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[21][20] |
Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ.
