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]Not documented
Bed temperature°C35–45 (Bambu Lab); 50–70 (Fiberlogy)[4][5]130–150 (3DXTech)[3]
Enclosure / chamber requirement1–5Open frame is fine[4]Actively heated chamber required[17][18]
Part cooling fanFan on[4]Not documented
Warping tendency1–5None[4]Severe — heated chamber needed[17]
Overall printing difficulty1–5Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[19][4]Expert / industrial hardware only[17][18]
Extruder requirementNozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[19]Not documented
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[19][20]Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[17]
Abrasiveness1–5Moderately abrasive — wood fill[19]Non-abrasive when unfilled[3]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[19]Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 120 °C pre-dry before every print[21]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[4]Not documented
Equilibrium moisture content at ~50 % RH%1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[4]0.37 in 24 h and 1.1 at saturation on extruded stock (ASTM D570)[22]
Drying temperature & time55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[4][19]Not documented
Symptoms when wetBambu Lab flags pre-drying and ventilation as specific requirements for this grade[19]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][4]No dry-versus-conditioned figures are published; 3DXTech mandates a 120 °C, 4 h pre-dry before every print because trapped water flashes to steam at these nozzle temperatures[21]
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]55 (printed XY, ISO 527, 3DXTech) and 55 (printed on side long edge, ASTM D638, Stratasys PPSF); 79 at yield on extruded stock[3][6][22]
Young's modulusMPa2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[4][2][5]2100 (printed, ASTM D638, Stratasys PPSF) and 2310 (printed XY, ISO 527, 3DXTech); 2344 on extruded stock[3][6][22]
Elongation at break%4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[4][2][5]3 (printed, ISO 527 and ASTM D638) against 60 on extruded stock — printing costs PPSU almost all of its ductility[3][6][22]
Flexural strengthMPa55 ± 4 printed XY, ISO 178 (Bambu Lab)[4]110 (printed, ISO 178 and ASTM D790, 3DXTech and Stratasys PPSF agree); 91 on extruded stock[3][6][22]
Flexural modulusMPa2780 ± 120 printed XY, ISO 178 (Bambu Lab)[4]2200 (printed, ASTM D790, Stratasys PPSF) and 2215 (printed XY, ISO 178, 3DXTech)[3][6]
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]Izod notched 58.7 J/m and unnotched 165.5 J/m (printed, ASTM D256 Method A, Stratasys PPSF); 160 J/m notched on extruded stock[6][22]
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]Brittle — snaps with little warning[3]
Hardness (scale-specific)Shore A / Shore D / RockwellNot documentedRockwell M86 on printed PPSF (ASTM D785, Stratasys); M96 on extruded PPSU stock (and an unlabelled 123)[6][22]
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[24][25][26]Good. Printed PPSF holds 189 °C heat deflection at 1.8 MPa (ASTM D648) and extruded stock is rated 149 °C long-term service, but Ensinger does not claim the creep resistance it claims for PSU and PPS[6][22]
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[27][4]Not documented
Elasticity / flexibility1–5Rigid[4]Rigid[3]
Z strength as % of XY%58 by tensile, 51 by flexural (printed, Bambu Lab)[4]Not documented
Thermal Properties
HDT at 0.45 MPa°C60 (ISO 75, 0.45 MPa)[4]190 (printed XY, ISO 75 at 0.45 MPa, 3DXTech)[3]
HDT at 1.8 MPa°C57 (ISO 75, 1.8 MPa)[4]189 (printed, ASTM D648 at 264 psi, Stratasys PPSF); 207 on extruded stock, converted from 405 °F[6][22]
Glass transition (Tg)°C54 (Bambu Lab, DSC); Fiberlogy quotes 55–60[4][5]230 (DSC) — the highest glass transition in the dataset[3]
Melting point / Vicat°C156 peak melt (DSC)[4]Not documented
Continuous service temperature°CNot documented149 long-term service on extruded PPSU stock, converted from 300 °F[22]

Flammability / UL 94Not documentedUL 94 V-0 at 1.5 mm, rated on the base resin[3]
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[28]Not documented
Chemical resistanceNot documentedWithstands repeated steam autoclaving, the usual reason to choose PPSU over PSU; Stratasys also lists PPSF as passing 24 h stress-crack exposure to antifreeze, petrol, motor oil, power-steering, transmission and washer fluid at 23 °C and 100 °C[3][6]
Electrical & ESD propertiesNot documentedVolume resistivity 5e13 to 1.5e14 ohm-cm and dielectric strength 80-290 V/mil on printed PPSF (ASTM D257, D149)[6]
Health & Safety
Fume toxicity1–5Low hazard — minimal VOC and particle emission[29]Moderate — measurable VOCs and UFPs, ventilation advised. None of these polymers was in the chamber study, and all are processed far above the temperatures it covered[29]
Ventilation / filtration requirement1–5None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[19]Ventilated room or enclosure recommended[29]
Post-Processing
Sanding & machiningSands and stains like timber — the usual reason for choosing it[2]Not documented
Support material pairingSupport for PLA (Bambu Lab)[4]Not documented
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.[30]Dichloromethane dissolves it at 23 °C at every stress level; acetone solvates and softens unstressed PPSU (Solvay ESCR).[31]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[30][32]MEK ruptures stressed parts and toluene crazes them above 13.8 MPa; glass-filled grades survive where unfilled craze.[31]
Solvent welding & smoothing agentChloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[33][32]Dichloromethane cements PPSU and NMP softens residual resin; both are laboratory reagents, not workshop stock.[31]
