Maximum volumetric flow (mm³/s; see test conditions)mm³/s≈24 at 300 mm/s with a 0.4 mm nozzle and 0.2 mm layer; 30 % more flow than regular PLA at the same temperature[1][17][19][22]Not documented

Effect of moisture on strengthPolymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[28]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[28]
Storage requirementSealed with desiccant below 20 % RH; shelf life at ambient is long[21][23]Not documented

Ventilation / filtration requirement1–5None needed in a normal room[37]None needed in a normal room[37]
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 & machiningWet sanding — dry sanding heats the surface by friction and smears it[35][27]Sands to a stone-like matte surface[3]
Gluing & solvent weldingCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[27][38]Not documented
Vapour / chemical smoothingNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[27]Not documented
Support material pairingPolySupport and PolyDissolve S1 (Polymaker)[1]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 inChloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[39]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[39]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[39][40]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[39][40]
Solvent welding & smoothing agentChloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[41][40]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[41][40]
