Identity & Market
Base polymer / chemistryPLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[1][2]Polyvinyl butyral — a printable thermoplastic whose surface can be smoothed with isopropyl alcohol instead of a hot solvent[3]
Densityg/cm³1.31 (Bambu Lab, ISO 1183) to 1.38 (Fiberlogy PLA Mineral, method not stated) — above plain PLA from the filler[2][1]1.10 (Polymaker PolySmooth, ISO 1183); Prusament PVB 1.10[3][4]
Typical priceUSD/kgMainstream 1 kg spools cluster near 21[5][6][7]1 kg-equivalent spools cluster near 80[8][9]

Printing Parameters
Nozzle temperature°C190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[2][1]215 +/- 10 (Prusament PVB)[4]
Bed temperature°C35–45 (Bambu Lab); 60 (Fiberlogy)[2][1]75 +/- 5 (Prusament PVB)[4]
Enclosure / chamber requirement1–5Open frame is fine[2][1]Open frame is fine[3]
Part cooling fanFan on; Fiberlogy specifies 75–100 %[2][1]100 % part cooling (Prusament PVB)[4]
Bed surface & adhesion aidCool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[2][1]Smooth PEI sheet or satin sheet; Prusa states a brim is not generally necessary[4]
Warping tendency1–5None[2]Not documented
Bed-adhesion difficulty1–5Sticks to anything[14]Not documented
Overall printing difficulty1–5Beginner — prints on any machine out of the box[2][1]Easy — minor profile tuning; it prints close to PLA[3]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[15][2][1]Brass fine indefinitely[3]
Abrasiveness1–5Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[1][2][16]Non-abrasive[3]
Nozzle clog risk1–5Very low[15]Moderate — needs dry filament and a clean nozzle; Prusa calls PVB very prone to absorbing moisture and requires a 60 °C, 4 h dry before every print[17][18]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed; PLA softens below 60 °C[19]Not documented
Hotend requirementNo special hot-end required[14]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.40 % saturated at 25 °C / 55 % RH[2]Very high (>2 %) — 2.36 % equilibrium water absorption (Polymaker PolySmooth), above every PLA and PETG grade here[3]
Equilibrium moisture content at ~50 % RH%0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[2]2.36 equilibrium water absorption (Polymaker PolySmooth); 2.09 for PolyCast; Prusament PVB takes up 0.18 in 24 h and 0.35 in 7 days at 24 °C and 22 % RH[3][20][4]
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][21]Maximum 60 °C for 4-8 h depending on how wet the filament is (Prusament PVB)[4]
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[18]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[18]Polymaker publishes no dry-versus-conditioned figures; at 2.36 % equilibrium uptake the material has to be kept dry to print cleanly[3][18]
Storage requirementSealed with desiccant below 20 % RH; shelf life at ambient is long[16][14]Sealed with desiccant[18]
Mechanical Properties

Elasticity / flexibility1–5Rigid[2]Rigid[3]
Z strength as % of XY%73 by tensile, 55 by flexural (printed, Bambu Lab)[2]98 (Prusament PVB, printed vertical against horizontal tensile yield, ISO 527-1: 49 +/- 5 against 50 +/- 5) — the most isotropic printed material in this dataset[4]

Water / humidity resistance in service1–5Good — insoluble in water[16]Not documented
Food contactBase resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[19]Not documented
Biodegradability / compostabilityIndustrially compostable only — needs sustained 55 °C; not home compostable[26][19]Not documented
RecyclabilityMechanically recyclable; not accepted in household plastic collection[26]Not documented
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission[27]Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[27]
Ventilation / filtration requirement1–5None needed in a normal room[27]Open a window / occasional ventilation[27]
Post-Processing
Sanding & machiningWet sanding — dry sanding heats the surface by friction and smears it[25][19]Not documented
Gluing & solvent weldingCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[19][28]Not documented
Vapour / chemical smoothingNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[19]Isopropyl alcohol vapour smoothing is the point of the material — Polymaker markets PolySmooth for hands-free post-processing to a layer-free surface[3]
Support material pairingSupport for PLA (Bambu Lab)[2]PolyDissolve S1 is rated for PVB (Polymaker)[29]
Dimensional accuracy & detailMatte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[2]PolyCast is the investment-casting variant of the same chemistry — it burns out cleanly rather than being smoothed[20]
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.[30]Isopropyl alcohol dissolves it; Prusa describes PVB as soluble only in IPA, and it is not water-soluble.[17]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[30][31]Not documented
Solvent welding & smoothing agentChloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[32][31]Isopropyl alcohol: brushed or sprayed on for speed, or several hours in IPA vapour for a glass-like surface.[31][17]
