Diameter tolerance± mm±0.03 (Bambu Lab)[5]±0.04 (Prusament)[3]
Printing Parameters
Nozzle temperature°C190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][2]270 ± 10 (Prusament)[3]
Bed temperature°C35–45 (Bambu Lab); 50–70 (Fiberlogy)[5][6]85 ± 10 (Prusament)[3]
Enclosure / chamber requirement1–5Open frame is fine[5]Enclosure recommended — Simplify3D lists an enclosure as a hardware requirement and Polymaker advises one below 70 °C ambient to stop warping and cracking[17][18]
Part cooling fanFan on[5]Off — Prusa runs 0 % except 100 % on bridges[3]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documented3.2 at Prusa's 40 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[3][19]
Warping tendency1–5None[5]High — enclosure needed for reliable large parts; Prusa recommends a brim[3]
Bed-adhesion difficulty1–5Not documentedVery difficult — special plates or slurry required[3]
Overall printing difficulty1–5Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[20][5]Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[3]
Extruder requirementNozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[20]Prusa states a hardened nozzle is necessary and recommends a brim[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[20][21]Hardened steel required — Prusa states plainly that a hardened nozzle is necessary[3]
Abrasiveness1–5Moderately abrasive — wood fill[20]Highly abrasive — standard CF composite[3]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[20]Moderate — needs dry filament and a clean nozzle; 3DXTech specifies a hardened 0.4 mm minimum nozzle and 0.25 mm layers or higher, and Prusa lists composites as a higher clogging risk[4][22]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5]Negligible (<0.1 % EMC) — Prusa measures 0.03 % in 24 h and 0.04 % in 7 days on its PP composite, the lowest figures it publishes for any filament[3]
Equilibrium moisture content at ~50 % RH%1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[5]0.03 after 24 h and 0.04 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[3]
Drying temperature & time55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][20]Not documented
Symptoms when wetBambu Lab flags pre-drying and ventilation as specific requirements for this grade[20]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[23][5]Not applicable in practice at 0.04 % equilibrium uptake[3]
Storage requirementNot documentedNo special storage needed[3]
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]21 ± 0.4 filament tensile yield (Prusament, ISO 527)[3]
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]14.5 ± 0.3 printed horizontal and 10.5 ± 0.8 printed vertical XZ (ISO 179-1, notched)[3]
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]Tough — absorbs impact, yields before breaking[3]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell R102 (and M95) on extruded unfilled PP stock (ASTM D785); no figure is published for a carbon-fibre PP filament[24]
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[25][26][27]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[28][5]Good[29]
Elasticity / flexibility1–5Rigid[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°C60 (ISO 75, 0.45 MPa)[5]158 (ISO 75, 0.45 MPa) — far above unfilled PP and above most engineering filaments[3]
HDT at 1.8 MPa°C57 (ISO 75, 1.8 MPa)[5]115 (ISO 75, 1.8 MPa)[3]
Glass transition (Tg)°C54 (Bambu Lab, DSC); Fiberlogy quotes 55–60[5][6]Not documented
Melting point / Vicat°C156 peak melt (DSC)[5]Not documented
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[30]Not documented
Chemical resistanceNot documentedExcellent against acids, alkalis and most solvents[18]
Water / humidity resistance in service1–5Not documentedExcellent — essentially unaffected[3]
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission[31]Low hazard — minimal VOC and particle emission. Inferred: no polyolefin was among the nine filaments in the Azimi chamber study, so this is a family-level judgement rather than a measurement[31]
Ventilation / filtration requirement1–5None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[20]Open a window / occasional ventilation. Inferred — no polyolefin was measured in the chamber study[31]
Dust & fibre handling hazardNot documentedCarbon fibre is bound in the matrix; sanding dust should not be inhaled[3]
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]Not documented
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.[32]None at room temperature; chloroform dissolves the matrix at 60 °C and xylene at about 118 °C, leaving the fibre.[33][34]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[32][35]Xylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it.[33]
Solvent welding & smoothing agentChloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[36][35]None — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically.[33]
