|---|---|---|
| Market snapshot | ||
| Listing priceUSD/kg; dated snapshots | $47.48/kg median; $37.49–$50.00/kg across 4 dated product listings | $19.09/kg median; $10.99–$32.16/kg across 10 dated product listings |
| Identity & Market | ||
| Base polymer / chemistry | PLA 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/cm³ | Filament 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/kg | 1 kg-equivalent spools cluster near 45[7][2][8] | Mainstream 1 kg spools cluster near 21[9][10][11] |
| Price range across brandsUSD/kg | 37–50 across brands; Polymaker LW-PLA 37, Bambu Lab Aero 45, colorFabb 50, PolyWood 50[8][7][2] | 11–32 across brands; budget house brands 11–19, Fiberlogy PLA Mineral 32[12][10][13] |
| Market availability1–5 | Available from several mainstream brands[7][8][2] | Stocked by most mainstream brands[12][11][9] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.6, 0.75, 0.8 and 1 kg spools[8][2] | 1.75 mm; 1 kg spools plus spool-less refills[9][14] |
| Typical applications | RC aircraft, drone airframes and large props where mass matters more than strength[1][2] | Display models and visible parts where a matte, non-reflective finish matters[6] |
| Diameter tolerance± mm | Not documented | ±0.03 (Bambu Lab)[15] |
| Printing Parameters | ||
| Nozzle temperature°C | 210–260 (Bambu Lab, foaming); 195–260 (colorFabb, foaming); 190–210 (Polymaker, pre-foamed)[1][2][3] | 190–230 (Bambu Lab); 190–210 (Fiberlogy PLA Mineral)[6][5] |
| Bed temperature°C | 35–45 (Bambu Lab); 50–60 (colorFabb); 25–60 (Polymaker)[1][2][3] | 35–45 (Bambu Lab); 60 (Fiberlogy)[6][5] |
| Enclosure / chamber requirement1–5 | Open frame is fine[3] | Open frame is fine[6][5] |
| Part cooling fan | Fan on[1][3] | Fan on; Fiberlogy specifies 75–100 %[6][5] |
| Bed surface & adhesion aid | Not documented | Cool plate, high-temperature plate or textured PEI with glue (Bambu Lab); smooth PEI, textured PEI or glass (Fiberlogy)[6][5] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 3.2–8 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 tendency1–5 | Not documented | None[6] |
| Bed-adhesion difficulty1–5 | Not documented | Sticks to anything[17] |
| Overall printing difficulty1–5 | Intermediate — 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 requirement | Bambu 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 required1–4 | Brass fine indefinitely[3][4] | Brass fine indefinitely[19][6][5] |
| Abrasiveness1–5 | Non-abrasive[3][4] | Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[5][6][20] |
| Nozzle clog risk1–5 | High — 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 sensitivity1–5 | Not documented | Moderate — good heatbreak cooling needed; PLA softens below 60 °C[21] |
| Hotend requirement | Not documented | No special hot-end required[17] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 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 & time | 55 °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 wet | Not documented | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[23] |
| Effect of moisture on strength | 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[23] | Polymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[23] |
| Storage requirement | Not documented | Sealed with desiccant below 20 % RH; shelf life at ambient is long[20][17] |

| Creep resistance / sustained load1–5 | Poor — no foamed-grade creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg, and the foam carries less solid[25][26][27] | Poor — 12 mm bar sagged to 18.7 mm over 5 days at 1.25 kg[24] |
| Fatigue / repeated-flex resistance1–5 | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and elongation at break falls to 2.6 % in XY and 1.2 % in Z[28][1] | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength (R = 0.2)[28][21] |

| Annealing response | Bambu Lab advises against annealing thin, low-infill Aero prints[1] | 50–60 °C for 6–12 h; some prints deform or warp, and a forced-air oven is required[6] |
| Flammability / UL 94 | Not documented | Flammable; no UL 94 rating published by the major brands[20][29] |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[21] | Degrades within weeks outdoors[21][30] |

| Support material pairing | Not documented | Support for PLA (Bambu Lab)[6] |
| Dimensional accuracy & detail | Foamed 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 in | Chloroform 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 by | Acetone, 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 agent | Chloroform 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] |
