Printing Parameters
Nozzle temperature°C260–280 (Bambu Lab); 250–270 (Polymaker)[2][1]190–230 (Polymaker); Bambu Lab Tough+ needs 220–250[3][4]
Bed temperature°C90–110 (Bambu Lab); 90–105 (Polymaker)[2][1]25–60 (Polymaker); 35–65 (Bambu Lab Tough+)[3][4]
Enclosure / chamber requirement1–5Enclosure required (passive) — Bambu Lab specifies a 45–60 °C chamber, Polymaker 70–100 °C[2][1]Open frame is fine[3][4]
Recommended chamber temperature°C45–60 (Bambu Lab); 70–100 (Polymaker)[2][1]Not documented
Part cooling fan0–60 % (Bambu Lab)[2]Fan on[3][4]
Bed surface & adhesion aidSmooth or textured PEI plate (Bambu Lab)[2]Textured or smooth PEI; Bambu Lab recommends glue stick or liquid glue for Tough+[3][4]
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][14]Not documented
Warping tendency1–5Severe — heated chamber needed[1][15]None[3]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[16][17]Sticks to anything[18]
Stringing / oozing tendency1–5Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[17]Slight — 1–3 mm retraction handles it[3][18]
Overall printing difficulty1–5Advanced — enclosure, hardware upgrades, tuning[2][15]Easy — minor profile tuning; Tough+ wants a hotter nozzle than plain PLA[3][4]
Hardware Wear & Reliability
Nozzle hardness required1–4Brass fine indefinitely[15]Brass fine indefinitely[19]
Abrasiveness1–5Non-abrasive[1]Non-abrasive[20][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]Very low[19]
Heat-creep / jam sensitivity1–5Slightly sensitive[16]Moderate — good heatbreak cooling needed; softens below 60 °C like plain PLA[22]
Hotend requirementAll-metal hot end required (Simplify3D)[16]No special hot-end required[18]
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][23]Low — 0.27 % saturated at 25 °C / 55 % RH[4]
Equilibrium moisture content at ~50 % RH%0.12 saturated at 25 °C / 55 % RH (Bambu Lab)[2]0.27 saturated at 25 °C / 55 % RH (Bambu Lab Tough+)[4]
Drying temperature & time75 °C for 6 h (Polymaker)[1]55 °C for 6–8 h; 65–75 °C for 12 h on a Bambu Lab X1 heatbed[3][4]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[24]Bubbling and popping at the nozzle, stringing, rough surface and weak layers[24]
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[17][24]Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for the modified grades; the loss shows as poor layer adhesion rather than a strength number[24]
Storage requirementAirtight containers with desiccant to prevent reabsorption[17]Sealed with desiccant below 20 % RH; shelf life at ambient is long[4][18]
Mechanical Properties
Tensile strength (XY)MPa60 ± 4 (Bambu Lab) and 67 ± 4.5 (Polymaker) printed XY, ISO 527[2][1]35–43 (printed XY, ISO 527); 53 on My Tech Fun 4×4 mm bars for Bambu Lab Tough[3][4][25][26]
Young's modulusMPa1670 ± 40 (Bambu Lab) and 2634 ± 182 (Polymaker) printed XY, ISO 527[2][1]1860–2150 (printed XY, ISO 527) — below plain PLA at 2300–3427[3][4][27][28]
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][29]5.1–5.7 (printed XY, ISO 527)[3][4]
Flexural strengthMPa96.6 ± 1.3 printed XY, ISO 178 (Polymaker)[1]62–65 (printed XY, ISO 178) — below plain PLA at 76–87[3][4][30][28]
Flexural modulusMPa2518 ± 53 printed XY, ISO 178 (Polymaker)[1]2140–2393 (printed XY, ISO 178)[3][4]
Charpy impact, notchedkJ/m²11.7 ± 1.6 printed XY, ISO 179, notched (Polymaker)[1]38.9–72.3 (printed XY, ISO 179, notched) — 5–9× plain PLA[3][4]
Other impact dataNotched Charpy 7.5 ± 1.6 kJ/m² at −30 °C printed XY (Polymaker, ISO 179-1/1eA)[1]Charpy unnotched 80.6 printed XY (Bambu Lab Tough+); CNC Kitchen measured ~20 vs 5 kJ/m² for PolyLite PLA[4][25]
Layer adhesion / Z tensileMPa21 ± 3 (Bambu Lab) and 46 ± 4.8 (Polymaker) printed Z, ISO 527[2][1]20.9–32.4 printed Z (ISO 527); 33.0 on My Tech Fun layer-adhesion bars vs 27.6 for PLA Basic[3][4][26]
Brittleness1–5Moderate[2][1]Tough — absorbs impact, yields before breaking[3][4][25]
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[31]78.8 Shore D measured on printed bars (My Tech Fun), against 75.3 for the same maker's plain PLA[32]
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[33][1]Poor — 12 mm bar sagged to 20.2 mm over 5 days at 1.25 kg, the same as plain PLA[26][34]
Fatigue / repeated-flex resistance1–5Not documentedBelow average — impact modifiers raise absorbed energy 5–9×; plain PLA ran 38 000–49 000 cycles at 30 % of tensile strength[35][4][25]
Elasticity / flexibility1–5Rigid[1]Rigid[3]
Z strength as % of XY%35 (Bambu Lab) to 69 (Polymaker), printed[2][1]60 (Bambu Lab Tough+) to 78 (PolyMax PLA), printed[3][4]
Thermal Properties
HDT at 0.45 MPa°C110 (Polymaker) and 113 (Bambu Lab), ISO 75 at 0.45 MPa[1][2]55 (PolyMax) to 61 (Tough+), ISO 75 at 0.45 MPa[3][4]
HDT at 1.8 MPa°C107 (Polymaker) and 108 (Bambu Lab), ISO 75 at 1.8 MPa[1][2]52 (PolyMax) to 58 (Tough+), ISO 75 at 1.8 MPa[3][4]
Glass transition (Tg)°C115 (Polymaker) and 145 (Bambu Lab), DSC[1][2]61 (DSC)[3][4]
Melting point / Vicat°CAmorphous — no melting point; Vicat 114 (Bambu Lab, ISO 306)[2]149–151 peak melt (DSC); Vicat 62 (ISO 306)[3][4]
Continuous service temperature°C113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[36]48–57 — loaded bars begin to move at this temperature: 48 for Polymaker PLA Pro, 50 for Sunlu PLA+, 52 for Bambu Lab Tough, 57 for PolyTerra PLA+[26][37][32][34]
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[31]96–99 for plain printed PLA (fibre Bragg grating, 25–50 °C); no grade-specific measurement published[38]
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][39]Flammable; no UL 94 rating published by the major brands[4][3]
Environment & Chemical
UV resistance1–5Degrades within weeks outdoors unless stabilised[17]Degrades within weeks outdoors[22][40]
Chemical resistanceWithstands oils, solvents and fuels; Polymaker rates it good against weak acids[17]Good against weak acids, oils and grease; poor against strong acids and alkalis[3][4]
Food contactBisphenol-A polycarbonate is not offered as food-contact filament[17]Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[22]
Biodegradability / compostabilityNot biodegradable[17]Industrially compostable only — needs sustained 55 °C; not home compostable[41][22]
RecyclabilityMechanically recyclable but not accepted in household plastic collection[17]Mechanically recyclable; not accepted in household plastic collection[41]
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[42]Low hazard — minimal VOC and particle emission[42]
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[42]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[42][15]None needed in a normal room[42]
Post-Processing
Sanding & machiningSands and machines well; the toughness means it cuts rather than chips[16]Wet sanding — dry sanding heats the surface by friction and smears it[40][22]
Gluing & solvent weldingCyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[16]Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[22][43]
Vapour / chemical smoothingNo practical vapour smoothing[16]No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[22]
Support material pairingPrints its own supports; 3DXTech sells a dedicated PC break-away support[16]PolySupport and PolyDissolve S1 (Polymaker); Support for PLA (Bambu Lab)[3][4]
Dimensional accuracy & detailNot documented55° overhangs and 30 mm bridges (Bambu Lab Tough+)[4]
Solvents & Solubility
Soluble inDichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[44]Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[45]
Softened or crazed byMethanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[44]Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[45][46]
Solvent welding & smoothing agentDichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[47]Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[48][46]
