Identity & Market
Base polymer / chemistryPLA with a blowing agent. Two distinct types: active-foaming grades that expand at the nozzle (Bambu Lab PLA Aero, colorFabb LW-PLA) and pre-foamed grades that do not (Polymaker PolyLite LW-PLA, PolyWood)[1][2][3][4]PLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[5][6]
Densityg/cm³Filament 1.21 (Bambu Lab) and 1.24 (colorFabb); pre-foamed filament 0.8 (PolyWood, at 21.5 °C) and 0.9 (Polymaker LW-PLA); foamed prints reach 0.40[1][2][3][4]1.31 (Bambu Lab, ISO 1183) to 1.38 (Fiberlogy PLA Mineral, method not stated) — above plain PLA from the filler[6][5]
Typical priceUSD/kg1 kg-equivalent spools cluster near 45[7][2][8]Mainstream 1 kg spools cluster near 21[9][10][11]

Maximum volumetric flow (mm³/s; see test conditions)mm³/s3.2–8 at the 40–100 mm/s colorFabb specifies and the 50–100 mm/s Polymaker specifies, on a 0.4 mm nozzle at 0.2 mm layer[3][2][16]Not documented
Warping tendency1–5Not documentedNone[6]
Bed-adhesion difficulty1–5Not documentedSticks to anything[17]
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; flow has to be cut to match the expansion[2]Beginner — prints on any machine out of the box[6][5]
Extruder requirementBambu Lab PLA Aero is 0.4 mm nozzle only on the store and wiki, while its own TDS lists 0.4, 0.6 and 0.8[1][18]Not documented
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[3][4]Brass fine indefinitely[19][6][5]
Abrasiveness1–5Non-abrasive[3][4]Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[5][6][20]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles; Bambu Lab warns the foamed extrudate swells and easily clogs the nozzle, and rules out 0.2 mm nozzles[18]Very low[19]
Heat-creep / jam sensitivity1–5Not documentedModerate — good heatbreak cooling needed; PLA softens below 60 °C[21]
Hotend requirementNot documentedNo special hot-end required[17]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.45 % saturated at 25 °C / 55 % RH (Bambu Lab); 0.40 % equilibrium (Polymaker)[1][3]Moderate — 0.40 % saturated at 25 °C / 55 % RH[6]
Equilibrium moisture content at ~50 % RH%0.45 saturated at 25 °C / 55 % RH (Bambu Lab); 0.40 equilibrium (Polymaker)[1][3]0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[6]
Drying temperature & time55 °C for 6–8 h[1][3]50 °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[6][5][22]
Symptoms when wetNot documentedBubbling and popping at the nozzle, stringing, rough surface and weak layers[23]
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[23]Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[23]
Storage requirementNot documentedSealed with desiccant below 20 % RH; shelf life at ambient is long[20][17]

Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[21]Degrades within weeks outdoors[21][30]

Food contactNot documentedBase resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[21]
Biodegradability / compostabilityNot documentedIndustrially compostable only — needs sustained 55 °C; not home compostable[31][21]

Ventilation / filtration requirement1–5None needed in a normal room[32]None needed in a normal room[32]
Post-Processing
Sanding & machiningNot documentedWet sanding — dry sanding heats the surface by friction and smears it[30][21]
Gluing & solvent weldingNot documentedCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[21][33]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[21]
Support material pairingNot documentedSupport for PLA (Bambu Lab)[6]
Dimensional accuracy & detailFoamed surfaces are rough and matte; dimensional accuracy depends on holding the foaming temperature steady[1][2]Matte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[6]
Solvents & Solubility
Soluble inChloroform dissolves the PLA matrix; the foamed wall wicks solvent right through instead of only skinning over.[34]Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[34]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[34][35]Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[34][35]
Solvent welding & smoothing agentChloroform vapour reaches only the resin skin; no workshop-safe smoothing agent exists for PLA of any kind.[36][35]Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[36][35]
