| Identity & Market | ||
| Base polymer / chemistry | ASA with a heat-activated blowing agent that expands at the nozzle[1][2] | PLA filled with wood powder — 10–18 wt% (Bambu Lab SDS); colorFabb woodFill uses a PLA/PHA base with recycled wood fibre[3][4] |
| Densityg/cm³ | 0.99 filament (Bambu Lab, ISO 1183); Formfutura's grade reaches 0.33 g/cm³ fully expanded[1][2] | 1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[5][4][6] |
| Typical priceUSD/kg | 1 kg spools cluster near 50[7] | 1 kg spools cluster near 25; counting the 0.5 kg specialty spools the middle of the market is about 34[8][9][10] |
| Price range across brandsUSD/kg | 50 at Bambu Lab's 1 kg listing[7] | 14–76 across brands; SUNLU 14, ELEGOO 19, Bambu Lab 25, Prusament 44, Filament PM 49 on 0.5 kg spools, colorFabb 76[9][8][11][12][13][10] |
| Market availability1–5 | Niche, a handful of specialist brands[7][2] | Stocked by most mainstream brands[8][9][12][6] |
| Spool sizes & diameters | 1.75 mm; 1 kg spools[7] | 1.75 and 2.85 mm; 0.6, 0.85 and 1 kg spools[12][6][8] |
| Typical applications | Drone airframes, RC parts and floating or outdoor applications where mass matters and UV exposure rules out LW-PLA[2] | Decorative and model-making prints that are sanded and stained like timber[5][4] |
| Diameter tolerance± mm | Not documented | ±0.03 (Bambu Lab)[5] |
| Printing Parameters | ||
| Nozzle temperature°C | 240–280 (Bambu Lab); 220–285 (Formfutura), with foaming activating near 230 °C and peaking between 270 and 285 °C[1][2] | 190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][4] |
| Bed temperature°C | 80–90 (Bambu Lab); 50–90 (Formfutura)[1][2] | 35–45 (Bambu Lab); 50–70 (Fiberlogy)[5][6] |
| Enclosure / chamber requirement1–5 | Enclosure recommended — Bambu Lab specifies a 45–60 °C chamber[1][14] | Open frame is fine[5] |
| Recommended chamber temperature°C | 45–60 (Bambu Lab)[1] | Not documented |
| Part cooling fan | 0–80 % (Bambu Lab); 0–50 % (Formfutura)[1][2] | Fan on[5] |
| Bed surface & adhesion aid | PEI sheet, BuildTak or an adhesion aid such as Magigoo (Polymaker); Simplify3D also lists Kapton tape and ASA slurry[15][16] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 12 at Bambu Lab's 150 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[1][17] | Not documented |
| Warping tendency1–5 | Not documented | None[5] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[15] | Not documented |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[15] | Not documented |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning; flow has to be cut to match the expansion and the density follows nozzle temperature[2][1] | Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[18][5] |
| Extruder requirement | Not documented | Nozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[18] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[14] | 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[18][19] |
| Abrasiveness1–5 | Non-abrasive[14] | Moderately abrasive — wood fill[18] |
| Nozzle clog risk1–5 | Not documented | Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[18] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[16] | Not documented |
| Hotend requirement | No special hotend required[16] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | High — 0.80 % saturated at 25 °C / 55 % RH, nearly double unfilled Bambu Lab ASA[1][20] | High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5] |
| Equilibrium moisture content at ~50 % RH% | 0.80 saturated at 25 °C / 55 % RH (Bambu Lab)[1] | 1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[5] |
| Drying temperature & time | 80 °C for 8 h (Bambu Lab)[1] | 55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][18] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[21] | Bambu Lab flags pre-drying and ventilation as specific requirements for this grade[18] |
| Effect of moisture on strength | No dry-versus-conditioned figures are published; Polymaker groups the styrenics as moderate-sensitivity and absorbed water shows as bubbling and poor layer adhesion[21] | 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[21][5] |
| Storage requirement | Sealed with desiccant; Polymaker rates the styrenics moderate-sensitivity[21] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 32 ± 4 printed XY, ISO 527 (Bambu Lab)[1] | 26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[5][4][6] |
| Young's modulusMPa | 2010 ± 260 printed XY, ISO 527 (Bambu Lab)[1] | 2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[5][4][6] |
| Elongation at break% | 5.1 ± 1.6 printed XY, ISO 527 (Bambu Lab)[1] | 4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[5][4][6] |
| Flexural strengthMPa | 58 ± 6 printed XY, ISO 178 (Bambu Lab)[1] | 55 ± 4 printed XY, ISO 178 (Bambu Lab)[5] |
| Flexural modulusMPa | 1510 ± 120 printed XY, ISO 178 (Bambu Lab)[1] | 2780 ± 120 printed XY, ISO 178 (Bambu Lab)[5] |
| Charpy impact, notchedkJ/m² | 8.2 ± 1.6 printed XY, ISO 179, notched (Bambu Lab)[1] | 3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[5][4] |
| Other impact data | Charpy unnotched 32.0 ± 2.5 printed XY (Bambu Lab, ISO 179)[1] | Charpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[5][4] |
| Layer adhesion / Z tensileMPa | 21 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 24 against 58 in XY[1] | 15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[5] |
| Brittleness1–5 | Moderate[1] | Brittle — snaps with little warning[5] |
| Creep resistance / sustained load1–5 | Below average — no creep test found; the foamed structure drops modulus to 2010 MPa and load is carried by a lower solid fraction[1][20] | Poor — no wood-filled creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[22][23][24] |
| Fatigue / repeated-flex resistance1–5 | Moderate — no foamed-grade S-N curve; unfilled printed ASA holds a fatigue limit at 25 % of tensile strength[1][25] | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and the wood filler cuts elongation and the parts snap without warning[26][5] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[5] |
| Z strength as % of XY% | 66 by tensile, 41 by flexural (printed, Bambu Lab)[1] | 58 by tensile, 51 by flexural (printed, Bambu Lab)[5] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 85 (ISO 75, 0.45 MPa, Bambu Lab) against 100 for unfilled Bambu Lab ASA[1][20] | 60 (ISO 75, 0.45 MPa)[5] |
| HDT at 1.8 MPa°C | 78 (ISO 75, 1.8 MPa, Bambu Lab) against 92 for unfilled Bambu Lab ASA[1][20] | 57 (ISO 75, 1.8 MPa)[5] |
| Glass transition (Tg)°C | Not documented | 54 (Bambu Lab, DSC); Fiberlogy quotes 55–60[5][6] |
| Melting point / Vicat°C | Not documented | 156 peak melt (DSC)[5] |
| Continuous service temperature°C | 93 — Prusa publishes this as the temperature resistance of Prusament ASA[27] | Not documented |
| Flammability / UL 94 | Flammable; no UL 94 rating published[20] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Excellent — designed for permanent outdoor use; Formfutura states the foaming grade retains ApolloX's UV resistance[2][28] | Degrades within weeks outdoors[29] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[30] | Not documented |
| Food contact | Not food safe[15] | Not documented |
| Biodegradability / compostability | Not biodegradable[15] | Not documented |
| Recyclability | Not accepted in household plastic collection[15] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[31][14] | Low hazard — minimal VOC and particle emission[31] |
| Hazardous species emitted | Styrene. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea. Azimi et al. measured styrene from every styrenic filament tested but did not test ASA itself[14][31] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration[31][14] | None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[18] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[15] | Sands and stains like timber — the usual reason for choosing it[4] |
| Painting & finishing | Paints readily; ASA holds colour outdoors so many parts are left unpainted[15] | Not documented |
| Gluing & solvent welding | Solvent-welds with acetone[30] | Not documented |
| Vapour / chemical smoothing | Acetone vapour smoothing works[30] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a Support for ABS that also serves ASA[14] | Support for PLA (Bambu Lab)[5] |
| Dimensional accuracy & detail | Matte, textured surface that hides layer lines; colour lightens as the foaming degree rises, which doubles as a visual density cue[2] | Wood grain hides layer lines; colour darkens with nozzle temperature[5][4] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it (Polymaker); MEK, THF, ethyl acetate and the chlorinated solvents dissolve the styrenic backbone.[32][30] | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[33] |
| Softened or crazed by | Limonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[34] | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[33][35] |
| Solvent welding & smoothing agent | Acetone vapour, ~20 min at 80 °C over 5 mm of liquid; the foamed wall absorbs solvent, so cut the exposure well short.[35] | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[36][35] |
