| Identity & Market | ||
| Base polymer / chemistry | PLA filled with wood powder — 10–18 wt% (Bambu Lab SDS); colorFabb woodFill uses a PLA/PHA base with recycled wood fibre[1][2] | Polyvinylidene fluoride — a semi-crystalline fluoropolymer[3][4] |
| Densityg/cm³ | 1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[5][2][6] | 1.71 (ISO 1183) — the densest unfilled filament in the dataset[3] |
| Typical priceUSD/kg | 1 kg spools cluster near 25; counting the 0.5 kg specialty spools the middle of the market is about 34[7][8][9] | 1 kg-equivalent spools cluster near 251[10] |
| Price range across brandsUSD/kg | 14–76 across brands; SUNLU 14, ELEGOO 19, Bambu Lab 25, Prusament 44, Filament PM 49 on 0.5 kg spools, colorFabb 76[8][7][11][12][13][9] | 251 at 3DXTech's 750 g pricing — the most expensive material in the whole dataset[10] |
| Market availability1–5 | Stocked by most mainstream brands[7][8][12][6] | Special order, 1–2 makers worldwide[10][14] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.6, 0.85 and 1 kg spools[12][6][7] | 1.75 and 2.85 mm; 750 g spools[10] |
| Typical applications | Decorative and model-making prints that are sanded and stained like timber[5][2] | Chemical-plant fittings, semiconductor handling and parts needing outstanding UV and chemical resistance[3] |
| Diameter tolerance± mm | ±0.03 (Bambu Lab)[5] | Not documented |
| Printing Parameters | ||
| Nozzle temperature°C | 190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][2] | Not documented |
| Bed temperature°C | 35–45 (Bambu Lab); 50–70 (Fiberlogy)[5][6] | 70–110 (3DXTech FluorX)[3] |
| Enclosure / chamber requirement1–5 | Open frame is fine[5] | Enclosure required (passive)[3] |
| Part cooling fan | Fan on[5] | Not documented |
| Warping tendency1–5 | None[5] | High — enclosure needed for reliable large parts[3] |
| Overall printing difficulty1–5 | Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[15][5] | Expert / industrial hardware only[3][4] |
| Extruder requirement | Nozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[15] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | 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[15][16] | Brass fine indefinitely for unfilled grades[3] |
| Abrasiveness1–5 | Moderately abrasive — wood fill[15] | Non-abrasive when unfilled[3] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[15] | Low — 3DXTech lists no special nozzle concerns, no minimum layer height and states drying is not required[14] |
| Other hardware wear | Not documented | Hydrogen fluoride released on overheating is extremely corrosive and will attack hotend and enclosure metalwork as well as people[4] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5] | Negligible (<0.1 % EMC) — fluoropolymers are essentially non-hygroscopic[3] |
| Equilibrium moisture content at ~50 % RH% | 1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[5] | Not documented |
| Drying temperature & time | 55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][15] | Not documented |
| Symptoms when wet | Bambu Lab flags pre-drying and ventilation as specific requirements for this grade[15] | Not documented |
| Effect of moisture on strength | 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[17][5] | Not applicable in practice — 3DXTech states drying is not required for PVDF, so there is no moisture-driven strength loss to measure[14] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[5][2][6] | 51 at break (printed XY, ISO 527)[3] |
| Young's modulusMPa | 2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[5][2][6] | 2450 (printed XY, ISO 527)[3] |
| Elongation at break% | 4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[5][2][6] | 25 at break (printed XY, ISO 527)[3] |
| Flexural strengthMPa | 55 ± 4 printed XY, ISO 178 (Bambu Lab)[5] | 50 (printed XY, ISO 178)[3] |
| Flexural modulusMPa | 2780 ± 120 printed XY, ISO 178 (Bambu Lab)[5] | 1800 (printed XY, ISO 178)[3] |
| Charpy impact, notchedkJ/m² | 3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[5][2] | Not documented |
| Other impact data | Charpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[5][2] | Izod 133 J/m on extruded PVDF stock, converted from 2.49 ft-lb/in (ASTM D256)[18] |
| Layer adhesion / Z tensileMPa | 15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[5] | Not documented |
| Brittleness1–5 | Brittle — snaps with little warning[5] | Tough — absorbs impact, yields before breaking[3] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell M79 on extruded PVDF stock (ASTM D785)[18] |
| Creep resistance / sustained load1–5 | 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[19][20][21] | Not documented |
| 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 the wood filler cuts elongation and the parts snap without warning[22][5] | Not documented |
| Elasticity / flexibility1–5 | Rigid[5] | Slightly flexible in thin sections[3] |
| Z strength as % of XY% | 58 by tensile, 51 by flexural (printed, Bambu Lab)[5] | Not documented |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 60 (ISO 75, 0.45 MPa)[5] | 149 on extruded PVDF stock (ASTM D648 at 66 psi; converted from 300 °F)[18] |
| HDT at 1.8 MPa°C | 57 (ISO 75, 1.8 MPa)[5] | 113 on extruded PVDF stock (ASTM D648 at 264 psi; converted from 235 °F)[18] |
| Glass transition (Tg)°C | 54 (Bambu Lab, DSC); Fiberlogy quotes 55–60[5][6] | Not documented |
| Melting point / Vicat°C | 156 peak melt (DSC)[5] | 170 melting (ISO 11357)[3] |
| Continuous service temperature°C | Not documented | 149 long term and short term on extruded PVDF stock (converted from 300 °F)[18] |
| Thermal expansion (CTE)µm/m·K | Not documented | 127.8 (extruded PVDF stock, ASTM D696; source states 7.1e-5 in/in/°F) — the highest thermal expansion of any engineering polymer in this dataset[18] |
| Flammability / UL 94 | Not documented | UL 94 V-0 on extruded PVDF stock; Ensinger lists inherent flame resistance[18] |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[23] | Excellent — designed for permanent outdoor use; Ensinger lists good UV and weather resistance and high gamma radiation resistance for PVDF stock[3][18] |
| Chemical resistance | Not documented | Outstanding — resistant to most acids, solvents and oxidising agents, which is the reason to use it[3] |
| Water / humidity resistance in service1–5 | Not documented | Excellent — essentially unaffected[3] |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission[24] | Very high — toxic decomposition products; local exhaust mandatory. Above 315 °C thermal decomposition yields hydrofluoric acid, hydrogen cyanide and carbon monoxide[4] |
| Hazardous species emitted | Not documented | Above 315 °C: hydrofluoric acid, hydrogen cyanide, phenols, carbon monoxide, carbon dioxide and dense smoke. HF is extremely corrosive, its skin burns may not be immediately visible or painful, and exposure can be fatal by skin absorption, inhalation or ingestion[4] |
| Ventilation / filtration requirement1–5 | None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[15] | Local exhaust to outside / fume hood — the SDS states local exhaust is preferred[4] |
| Dust & fibre handling hazard | Not documented | Molten polymer causes thermal burns and must not be pulled off the skin. If HF is detected during a decomposition event, cut the heat but keep the extraction running, ventilate, and clear non-essential people from the area[4] |
| Post-Processing | ||
| Sanding & machining | Sands and stains like timber — the usual reason for choosing it[2] | Not documented |
| Support material pairing | Support for PLA (Bambu Lab)[5] | Not documented |
| Dimensional accuracy & detail | Wood grain hides layer lines; colour darkens with nozzle temperature[5][2] | The processing window sits well below the 315 °C decomposition threshold, so nozzle temperature must be controlled rather than raised to chase flow[3][4] |
| Solvents & Solubility | ||
| Soluble in | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[25] | THF, MEK, DMF, DMAc, NMP, DMSO and trimethyl phosphate dissolve 5–10 wt% at ambient — Arkema's active solvents, all lab reagents.[26] |
| Softened or crazed by | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[25][27] | Acetone, MIBK, cyclohexanone, butyl acetate and glycol ethers swell it; alkalis above pH 12 attack the homopolymer.[26][28] |
| Solvent welding & smoothing agent | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[29][27] | None for the workshop — the active solvents (NMP, DMAc, DMF) are laboratory reagents used for casting membranes, not joints.[26] |
