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]Styrene-ethylene-butadiene-styrene thermoplastic elastomer — a styrenic rubber, not a polyurethane[3]
Densityg/cm³1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[4][2][5]1.044 printed part density (BASF Ultrafuse TPS 90A, ISO 1183-1) — the lightest elastomer here[3]
Typical priceUSD/kg1 kg spools cluster near 25; counting the 0.5 kg specialty spools the middle of the market is about 34[6][7][8]1 kg-equivalent spools cluster near 77[9]
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[7][6][10][11][12][8]77 for the Recreus 600 g spool; Proto-pasta only lists a 50 g coil, which prices at 120[9][13]
Market availability1–5Stocked by most mainstream brands[6][7][11][5]Niche, a handful of specialist brands[3][13][9]
Spool sizes & diameters1.75 and 2.85 mm; 0.6, 0.85 and 1 kg spools[11][5][6]1.75 and 2.85 mm; 0.05 and 0.6 kg spools[3][9]
Typical applicationsDecorative and model-making prints that are sanded and stained like timber[4][2]Soft-touch overmoulds and skin-contact parts where a non-polyurethane elastomer is wanted[3]
Diameter tolerance± mm±0.03 (Bambu Lab)[4]Not documented
Printing Parameters
Nozzle temperature°C190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[4][2]260–280 (BASF Ultrafuse TPS 90A) — far hotter than any TPU here[3]
Bed temperature°C35–45 (Bambu Lab); 50–70 (Fiberlogy)[4][5]70–90 (BASF Ultrafuse TPS 90A)[3]
Enclosure / chamber requirement1–5Open frame is fine[4]Open frame is fine[3]
Part cooling fanFan on[4]Not documented
Bed surface & adhesion aidNot documentedPEI sheet or painter's tape; Polymaker warns TPU can over-stick and advises a glue stick as a release agent[14][15]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented0.8–2.4 at the 10–30 mm/s BASF specifies on a 0.4 mm nozzle at 0.2 mm layer — the slowest material in this group[3]
Warping tendency1–5None[4]Not documented
Overall printing difficulty1–5Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[16][4]Advanced — enclosure, hardware upgrades, tuning[3]
Extruder requirementNozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[16]Nozzle 0.4 mm or larger; BASF caps print speed at 10–30 mm/s[3]
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[16][17]Brass fine indefinitely[18]
Abrasiveness1–5Moderately abrasive — wood fill[16]Non-abrasive[18]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[16]Moderate — needs dry filament and a clean nozzle; BASF caps print speed at 10–30 mm/s and Simplify3D warns that raised feed rates on flexibles most likely end in a jam[14][3]
Hotend requirementNot documentedNo special hot-end required, but a direct-drive extruder is (Simplify3D)[14]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[4]Negligible (<0.1 % EMC) — BASF states drying is not necessary, unique among the elastomers here[3]
Equilibrium moisture content at ~50 % RH%1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[4]Not documented
Drying temperature & time55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[4][16]None — BASF states Ultrafuse TPS 90A arrives in a printable condition and drying is not necessary[3]
Symptoms when wetBambu Lab flags pre-drying and ventilation as specific requirements for this grade[16]Bubbling and popping at the nozzle, stringing and a rough surface[19]
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][4]Not applicable — the SEBS chemistry has no amide or ester linkages to take up water, and BASF specifies no drying at all[3]
Storage requirementNot documentedSealed with desiccant; often kept in a dryer during the print[19]
Mechanical Properties
Tensile strength (XY)MPa26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[4][2][5]Not documented

Flexural strengthMPa55 ± 4 printed XY, ISO 178 (Bambu Lab)[4]Not documented
Flexural modulusMPa2780 ± 120 printed XY, ISO 178 (Bambu Lab)[4]Not documented
Charpy impact, notchedkJ/m²3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[4][2]Not documented
Other impact dataCharpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[4][2]Not documented
Layer adhesion / Z tensileMPa15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[4]Not documented
Brittleness1–5Brittle — snaps with little warning[4]Very ductile — bends far before failing[3]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documented89 Shore A and 29 Shore D (BASF Ultrafuse TPS 90A, ISO 7619-1)[3]
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]Poor — no SEBS creep test; a printed 95A TPU bar crept from 74.5 to 82.7 mm over 5 days at 1.25 kg[23]
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[24][4]Excellent — living hinges viable[15]
Elasticity / flexibility1–5Rigid[4]Rubbery / highly elastic[3]
Z strength as % of XY%58 by tensile, 51 by flexural (printed, Bambu Lab)[4]Not documented
Wear resistance & frictionNot documentedAbrasion 111 mm³ (ISO 4649) — the poorest abrasion resistance in this group, well behind TPU[3]
Thermal Properties

HDT at 1.8 MPa°C57 (ISO 75, 1.8 MPa)[4]Not documented
Glass transition (Tg)°C54 (Bambu Lab, DSC); Fiberlogy quotes 55–60[4][5]Not documented
Melting point / Vicat°C156 peak melt (DSC)[4]242–249 melting (BASF Ultrafuse TPS 90A, ISO 11357-3)[3]
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[25]Good — years with some colour shift; Polymaker lists UV exposure among the conditions TPU withstands[15]
Chemical resistanceNot documentedWithstands industrial solvents and UV exposure (Polymaker)[15]
Water / humidity resistance in service1–5Not documentedExcellent — essentially unaffected[3]
Food contactNot documentedNot food safe without specific certification (Polymaker)[15]
Biodegradability / compostabilityNot documentedNot biodegradable[15]
RecyclabilityNot documentedNot accepted in household plastic collection[15]
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission[26]Low hazard — minimal VOC and particle emission; TPU was not among the nine filaments in the chamber study[26]
Ventilation / filtration requirement1–5None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[16]Open a window / occasional ventilation[26]
Post-Processing
Sanding & machiningSands and stains like timber — the usual reason for choosing it[2]Difficult to sand or smooth; Polymaker limits post-processing to trimming or tumbling[15]
Gluing & solvent weldingNot documentedCyanoacrylate bonds TPU; no common solvent welds it[15]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing[15]
Support material pairingSupport for PLA (Bambu Lab)[4]Polymaker warns TPU supports are often very difficult to remove[15]
Dimensional accuracy & detailWood grain hides layer lines; colour darkens with nozzle temperature[4][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]Toluene dissolves SEBS at room temperature — Kraton quotes solution viscosity at 25 % mass in toluene, 25 °C.[28]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[27][29]Soaking in hydrocarbon solvents and oils deteriorates it; short exposures are tolerated. Resists water, acids and bases.[28]
Solvent welding & smoothing agentChloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[30][29]Toluene will weld it, though the joint stays soft; no workshop-safe agent, and vapour smoothing is not practical.[28]
