Printing Parameters
Nozzle temperature°C190–230 (Bambu Lab)[2]190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][4]

Enclosure / chamber requirement1–5Open frame is fine[2]Open frame is fine[5]
Part cooling fanFan on[2]Fan on[5]
Warping tendency1–5Not documentedNone[5]
Overall printing difficulty1–5Easy — minor profile tuning; 0.2 mm nozzles are not usable[17]Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[17][5]
Extruder requirementNozzles below 0.4 mm are not compatible (Bambu Lab)[17]Nozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[17]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass 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[17]Brass acceptable; hardened steel for volume work — Bambu Lab's PLA compatibility table lists no hardened-nozzle requirement, but its nozzle guide names wood among the abrasive filaments hardened steel exists for[17][18]
Abrasiveness1–5Moderately abrasive — stone fill[17][1]Moderately abrasive — wood fill[17]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle[17]Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[17]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.44 % saturated at 25 °C / 55 % RH[2]High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5]

Drying temperature & timeNot documented55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][17]
Symptoms when wetNot documentedBambu Lab flags pre-drying and ventilation as specific requirements for this grade[17]
Effect of moisture on strengthPolymaker 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[19]No dry-versus-conditioned figures are published. At 1.25 % saturated uptake the practical loss shows as poor layer adhesion, rough surface and weak layers[19][5]

Dust & fibre handling hazardFormfutura'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[1]Not documented
Post-Processing
Sanding & machiningSands to a stone-like matte surface[1]Sands and stains like timber — the usual reason for choosing it[4]

Dimensional accuracy & detailMatte mineral surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[2]Wood grain hides layer lines; colour darkens with nozzle temperature[5][4]
Solvents & Solubility
Soluble inChloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[26]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[26]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[26][27]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[26][27]
Solvent welding & smoothing agentChloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[28][27]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[28][27]
