Identity & Market
Base polymer / chemistryPLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[1][2]Polypropylene reinforced with chopped glass fibre[3][4]
Densityg/cm³1.31 (Bambu Lab, ISO 1183) to 1.38 (Fiberlogy PLA Mineral, method not stated) — above plain PLA from the filler[2][1]1.12 (Prusament PP Glass Fiber, ISO 1183) — the glass lifts it above water[3]

Diameter tolerance± mm±0.03 (Bambu Lab)[14]±0.04 (Prusament)[3]
Printing Parameters
Nozzle temperature°C190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[2][1]245 ± 10 (Prusament) — 25 °C below the carbon-fibre grade[3][15]
Bed temperature°C35–45 (Bambu Lab); 60 (Fiberlogy)[2][1]95 ± 10 (Prusament)[3]
Enclosure / chamber requirement1–5Open frame is fine[2][1]Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[16][17]
Part cooling fanFan on; Fiberlogy specifies 75–100 %[2][1]Off — Prusa runs 0 % except 100 % on bridges[3]
Bed surface & adhesion aidCool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[2][1]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented4 at Prusa's 50 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[3][18]
Warping tendency1–5None[2]High — enclosure needed for reliable large parts; Prusa recommends a brim[3]
Bed-adhesion difficulty1–5Sticks to anything[19]Very difficult — special plates or slurry required[3]
Overall printing difficulty1–5Beginner — prints on any machine out of the box[2][1]Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[3]
Extruder requirementNot documentedPrusa states a hardened nozzle is necessary and recommends a brim[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[20][2][1]Hardened steel required[3]
Abrasiveness1–5Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[1][2][21]Highly abrasive — standard GF composite[3]
Nozzle clog risk1–5Very low[20]Moderate — needs dry filament and a clean nozzle; Prusa lists higher risk of nozzle clogging for glass-filled composites[22]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed; PLA softens below 60 °C[23]Not documented
Hotend requirementNo special hot-end required[19]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.40 % saturated at 25 °C / 55 % RH[2]Low (0.1–0.3 %) — 0.11 % at both 24 h and 7 days, higher than the carbon-fibre grade's 0.04 % but still very low[3][15]
Equilibrium moisture content at ~50 % RH%0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[2]0.11 after 24 h and 0.11 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[3]
Drying temperature & time50 °C for 8 h in a forced-air dryer, or 60–70 °C for 12 h on an X1 heatbed; Fiberlogy specifies 50 °C for 6 h[2][1][24]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[25]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[25]Not applicable in practice at 0.11 % equilibrium uptake[3]
Storage requirementSealed with desiccant below 20 % RH; shelf life at ambient is long[21][19]No special storage needed[3]

Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[23][30]Not documented
Chemical resistanceGood against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[29][23]Excellent against acids, alkalis and most solvents[17]
Water / humidity resistance in service1–5Good — insoluble in water[21]Excellent — essentially unaffected[3]
Food contactBase resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[23]Not documented
Biodegradability / compostabilityIndustrially compostable only — needs sustained 55 °C; not home compostable[31][23]Not documented
RecyclabilityMechanically recyclable; not accepted in household plastic collection[31]Not documented
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission[32]Low hazard — minimal VOC and particle emission. Inferred: no polyolefin was among the nine filaments in the Azimi chamber study, so this is a family-level judgement rather than a measurement[32]
Ventilation / filtration requirement1–5None needed in a normal room[32]Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[32]
Dust & fibre handling hazardNot documentedGlass fibre is bound in the matrix; avoid inhaling sanding dust[3]
Post-Processing
Sanding & machiningWet sanding — dry sanding heats the surface by friction and smears it[30][23]Not documented
Gluing & solvent weldingCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[23][33]Not documented
Vapour / chemical smoothingNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[23]Not documented
Support material pairingSupport for PLA (Bambu Lab)[2]Not documented
Dimensional accuracy & detailMatte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[2]Not documented
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.[34]None at room temperature; chloroform dissolves the matrix at 60 °C and xylene at about 118 °C, leaving the fibre.[35][36]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[34][37]Xylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[35]
Solvent welding & smoothing agentChloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[38][37]None — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[35]
