Identity & Market
Base polymer / chemistryPLA filled with wood powder — 10–18 wt% (Bambu Lab SDS); colorFabb woodFill uses a PLA/PHA base with recycled wood fibre[1][2]Break-away support compounded to survive high-temperature print chambers; 3DXTech sells separate grades for PC/ABS and for the PAEK and PEI class[3][4]
Densityg/cm³1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[5][2][6]1.37 (3DXTech THERMAX HTS1, ISO 1183)[3]
Typical priceUSD/kg1 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 168[10]
Price range across brandsUSD/kg14–76 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]100–290 across grades; 3DXTech THERMAX MTS1 100 at 2 kg, HTS2 168 at 250 g, HTS1 250 at 500 g, IEMAI 3D HT-SP 290 at 1 kg[10][14]
Market availability1–5Stocked by most mainstream brands[7][8][12][6]Niche, a handful of specialist brands[10][14]
Spool sizes & diameters1.75 and 2.85 mm; 0.6, 0.85 and 1 kg spools[12][6][7]1.75 mm; 250 g, 500 g, 1 kg and 2 kg spools[10]
Typical applicationsDecorative and model-making prints that are sanded and stained like timber[5][2]Support for PEEK, PEI and PC-class prints, where PVA and PLA-based supports would decompose[3][4]
Diameter tolerance± mm±0.03 (Bambu Lab)[5]Not documented
Printing Parameters
Nozzle temperature°C190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][2]Not documented
Bed temperature°C35–45 (Bambu Lab); 50–70 (Fiberlogy)[5][6]Not documented
Enclosure / chamber requirement1–5Open frame is fine[5]Actively heated chamber required — it is used inside high-temperature builds[3]
Part cooling fanFan on[5]Not documented
Warping tendency1–5None[5]Not documented
Overall printing difficulty1–5Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[15][5]Expert / industrial hardware only[3]
Extruder requirementNozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[15]A dual-extruder machine rated for high-temperature materials; 3DXTech states the grade is intended for dual-extruder printers designed to print high-temp materials[16]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass 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][17]Brass fine indefinitely[3]
Abrasiveness1–5Moderately abrasive — wood fill[15]Non-abrasive[3]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[15]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry for HTS1 and 80 °C for MTS1[16][18]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5]Not documented
Equilibrium moisture content at ~50 % RH%1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[5]Not documented
Drying temperature & time55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][15]Not documented
Symptoms when wetBambu Lab flags pre-drying and ventilation as specific requirements for this grade[15]Not documented
Effect of moisture on strengthNo dry-versus-conditioned figures are published. At 1.25 % saturated uptake the practical loss shows as poor layer adhesion, rough surface and weak layers[19][5]No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry for HTS1 and 80 °C for MTS1 because trapped water flashes to steam at these nozzle temperatures[16][18]
Mechanical Properties
Tensile strength (XY)MPa26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[5][2][6]Not documented
Young's modulusMPa2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[5][2][6]Not documented
Elongation at break%4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[5][2][6]Not documented
Flexural strengthMPa55 ± 4 printed XY, ISO 178 (Bambu Lab)[5]Not documented
Flexural modulusMPa2780 ± 120 printed XY, ISO 178 (Bambu Lab)[5]Not documented
Charpy impact, notchedkJ/m²3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[5][2]Not documented
Other impact dataCharpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[5][2]Not documented
Layer adhesion / Z tensileMPa15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[5]Not documented
Brittleness1–5Brittle — snaps with little warning[5]Not documented
Creep resistance / sustained load1–5Poor — no wood-filled creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[20][21][22]Not documented
Fatigue / repeated-flex resistance1–5Poor — 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[23][5]Not documented
Elasticity / flexibility1–5Rigid[5]Not documented
Z strength as % of XY%58 by tensile, 51 by flexural (printed, Bambu Lab)[5]Not documented
Wear resistance & frictionNot documented3DXTech marks tensile strength, modulus and elongation as not applicable for its support grades — they are not characterised as structural materials[3]
Thermal Properties
HDT at 0.45 MPa°C60 (ISO 75, 0.45 MPa)[5]Not documented
HDT at 1.8 MPa°C57 (ISO 75, 1.8 MPa)[5]205 (THERMAX HTS1, printed XY, ISO 75 at 1.8 MPa)[3]
Glass transition (Tg)°C54 (Bambu Lab, DSC); Fiberlogy quotes 55–60[5][6]225 (3DXTech THERMAX HTS1, DSC) — high enough to stay solid inside a PEI or PEEK build[3]
Melting point / Vicat°C156 peak melt (DSC)[5]Not documented
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[24]Not documented
Electrical & ESD propertiesNot documentedSurface resistance above 10^13 ohm/sq on all three THERMAX support grades (ASTM D257) — insulating[3][25][4]
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission[26]Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[26]
Ventilation / filtration requirement1–5None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[15]Open a window / occasional ventilation[26]
Post-Processing
Sanding & machiningSands and stains like timber — the usual reason for choosing it[2]Not documented
Support material pairingSupport for PLA (Bambu Lab)[5]This is the support material. MTS1 is matched to PC/ABS and PC; HTS1 and HTS2 to the higher-temperature classes[4][3]
Dimensional accuracy & detailWood grain hides layer lines; colour darkens with nozzle temperature[5][2]Not documented
Solvents & Solubility
Soluble inChloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[27]Aqueous alkali, not water: IEMAI specifies an alkaline bath in an ultrasonic cleaner until the support dissolves.[14]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[27][28]Not documented
Solvent welding & smoothing agentChloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[29][28]None — the alkaline bath dissolves the support rather than welding anything.[14]

Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ.
