Diameter tolerance± mm±0.03 (Bambu Lab PC FR)[2]±0.03 (Bambu Lab)[5]
Printing Parameters
Nozzle temperature°C260–280 (Bambu Lab); 250–270 (Polymaker)[2][1]190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][4]
Bed temperature°C90–110 (Bambu Lab); 90–105 (Polymaker)[2][1]35–45 (Bambu Lab); 50–70 (Fiberlogy)[5][6]
Enclosure / chamber requirement1–5Enclosure required (passive) — Bambu Lab specifies a 45–60 °C chamber, Polymaker 70–100 °C[2][1]Open frame is fine[5]
Recommended chamber temperature°C45–60 (Bambu Lab); 70–100 (Polymaker)[2][1]Not documented
Part cooling fan0–60 % (Bambu Lab)[2]Fan on[5]
Bed surface & adhesion aidSmooth or textured PEI plate (Bambu Lab)[2]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s24 at Bambu Lab's 300 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[2][15]Not documented
Warping tendency1–5Severe — heated chamber needed[1][16]None[5]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[17][18]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[18]Not documented
Overall printing difficulty1–5Advanced — enclosure, hardware upgrades, tuning[2][16]Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[19][5]
Extruder requirementNot documentedNozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[19]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[16]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[19][20]
Abrasiveness1–5Non-abrasive[1]Moderately abrasive — wood fill[19]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a 6 h pre-dry at 80 °C[21]Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[19]
Heat-creep / jam sensitivity1–5Slightly sensitive[17]Not documented
Hotend requirementAll-metal hot end required (Simplify3D)[17]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Low (0.1–0.3 %) — 0.12 % saturated at 25 °C / 55 % RH (Bambu Lab), half that of unfilled Bambu Lab PC[2][22]High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5]
Equilibrium moisture content at ~50 % RH%0.12 saturated at 25 °C / 55 % RH (Bambu Lab)[2]1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[5]
Drying temperature & time75 °C for 6 h (Polymaker)[1]55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][19]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[23]Bambu Lab flags pre-drying and ventilation as specific requirements for this grade[19]
Effect of moisture on strengthNo dry-versus-conditioned figures are published. Polymaker calls PC highly hygroscopic and requires a 70–80 °C dry for 6–8 h; run wet, the loss shows as surface defects and poor layer adhesion[18][23]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[23][5]
Storage requirementAirtight containers with desiccant to prevent reabsorption[18]Not documented
Mechanical Properties
Tensile strength (XY)MPa60 ± 4 (Bambu Lab) and 67 ± 4.5 (Polymaker) printed XY, ISO 527[2][1]26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[5][4][6]
Young's modulusMPa1670 ± 40 (Bambu Lab) and 2634 ± 182 (Polymaker) printed XY, ISO 527[2][1]2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[5][4][6]
Elongation at break%2.4 ± 0.3 (Bambu Lab) and 3.49 ± 0.7 (Polymaker) at break, printed XY, ISO 527 — the retardant roughly halves unfilled PC's elongation[2][1][24]4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[5][4][6]
Flexural strengthMPa96.6 ± 1.3 printed XY, ISO 178 (Polymaker)[1]55 ± 4 printed XY, ISO 178 (Bambu Lab)[5]
Flexural modulusMPa2518 ± 53 printed XY, ISO 178 (Polymaker)[1]2780 ± 120 printed XY, ISO 178 (Bambu Lab)[5]
Charpy impact, notchedkJ/m²11.7 ± 1.6 printed XY, ISO 179, notched (Polymaker)[1]3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[5][4]
Other impact dataNotched Charpy 7.5 ± 1.6 kJ/m² at −30 °C printed XY (Polymaker, ISO 179-1/1eA)[1]Charpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[5][4]
Layer adhesion / Z tensileMPa21 ± 3 (Bambu Lab) and 46 ± 4.8 (Polymaker) printed Z, ISO 527[2][1]15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[5]
Brittleness1–5Moderate[2][1]Brittle — snaps with little warning[5]
Hardness (scale-specific)Shore A / Shore D / RockwellRockwell 70 (118) — the source does not name the scales and Shore D 79 on extruded unfilled PC stock (ASTM D785, D2240); no figure is published for a flame-retardant filament[25]Not documented
Creep resistance / sustained load1–5Good. Moulded unfilled PC sustained 41 MPa tensile creep at room temperature without breaking, but the retardant package drops the glass transition to 115 °C in Polymaker's grade, so the unfilled rating is not carried over in full[26][1]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[27][28][29]
Fatigue / repeated-flex resistance1–5Not documentedPoor — 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[30][5]
Elasticity / flexibility1–5Rigid[1]Rigid[5]
Z strength as % of XY%35 (Bambu Lab) to 69 (Polymaker), printed[2][1]58 by tensile, 51 by flexural (printed, Bambu Lab)[5]
Thermal Properties

Continuous service temperature°C113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[31]Not documented
Thermal expansion (CTE)µm/m·K68.4 on extruded unfilled PC stock (ASTM D696; source states 3.8e-5 in/in/°F); no figure is published for a flame-retardant grade[25]Not documented
Flammability / UL 94UL 94 V-0 (Polymaker PolyMax PC-FR); 3DXTech rates its FR PC/ABS V-0 at 1.5 mm on the base resin[1][32]Not documented
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors unless stabilised[18]Degrades within weeks outdoors[33]
Chemical resistanceWithstands oils, solvents and fuels; Polymaker rates it good against weak acids[18]Not documented
Food contactBisphenol-A polycarbonate is not offered as food-contact filament[18]Not documented
Biodegradability / compostabilityNot biodegradable[18]Not documented
RecyclabilityMechanically recyclable but not accepted in household plastic collection[18]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[34]Low hazard — minimal VOC and particle emission[34]
Ultrafine-particle emission rateparticles/min≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[34]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[34][16]None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[19]
Post-Processing
Sanding & machiningSands and machines well; the toughness means it cuts rather than chips[17]Sands and stains like timber — the usual reason for choosing it[4]
Gluing & solvent weldingCyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[17]Not documented
Vapour / chemical smoothingNo practical vapour smoothing[17]Not documented
Support material pairingPrints its own supports; 3DXTech sells a dedicated PC break-away support[17]Support for PLA (Bambu Lab)[5]
Dimensional accuracy & detailNot documentedWood grain hides layer lines; colour darkens with nozzle temperature[5][4]
Solvents & Solubility
Soluble inDichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[35]Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[36]
Softened or crazed byMethanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[35]Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[36][37]
Solvent welding & smoothing agentDichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[38]Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[39][37]
