Market snapshot
Listing priceUSD/kg; dated snapshots$180.00/kg median; $180.00–$180.00/kg across 1 dated product listings$98.25/kg median; $76.50–$120.00/kg across 2 dated product listings
Identity & Market
Base polymer / chemistryPolycarbonate compounded with a conductive filler for static-dissipative parts[1]Styrene-ethylene-butadiene-styrene thermoplastic elastomer — a styrenic rubber, not a polyurethane[2]
Densityg/cm³1.24 (ISO 1183, 3DXTech); Stratasys specific gravity 1.195 (ASTM D792)[1][3]1.044 printed part density (BASF Ultrafuse TPS 90A, ISO 1183-1) — the lightest elastomer here[2]
Typical priceUSD/kg1 kg-equivalent spools cluster near 180[4]1 kg-equivalent spools cluster near 77[5]
Price range across brandsUSD/kg180 at 3DXTech's 750 g pricing — the most expensive material in this group[4]77 for the Recreus 600 g spool; Proto-pasta only lists a 50 g coil, which prices at 120[5][6]
Market availability1–5Special order, 1–2 makers worldwide[4]Niche, a handful of specialist brands[2][6][5]
Spool sizes & diameters1.75 and 2.85 mm; 750 g spools plus Stratasys-compatible cartridges[4]1.75 and 2.85 mm; 0.05 and 0.6 kg spools[2][5]
Typical applicationsElectronics fixtures and trays that need PC heat resistance and static dissipation together[1]Soft-touch overmoulds and skin-contact parts where a non-polyurethane elastomer is wanted[2]
Printing Parameters
Nozzle temperature°CNot documented260–280 (BASF Ultrafuse TPS 90A) — far hotter than any TPU here[2]
Bed temperature°CNot documented70–90 (BASF Ultrafuse TPS 90A)[2]
Enclosure / chamber requirement1–5Enclosure required (passive)[7][8]Open frame is fine[2]
Bed surface & adhesion aidPEI with a glue stick or a commercial adhesive[9]PEI sheet or painter's tape; Polymaker warns TPU can over-stick and advises a glue stick as a release agent[10][11]
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[2]
Warping tendency1–5Severe — heated chamber needed[7][8]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[9][12]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[12]Not documented
Overall printing difficulty1–5Advanced — enclosure, hardware upgrades, tuning[7]Advanced — enclosure, hardware upgrades, tuning[2]
Extruder requirementNot documentedNozzle 0.4 mm or larger; BASF caps print speed at 10–30 mm/s[2]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Brass fine indefinitely[13]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Non-abrasive[13]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a 120 °C pre-dry[14]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[10][2]
Heat-creep / jam sensitivity1–5Slightly sensitive[9]Not documented
Hotend requirementAll-metal hot end required (Simplify3D)[9]No special hot-end required, but a direct-drive extruder is (Simplify3D)[10]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Low (0.1–0.3 %) — the PC matrix takes up 0.15–0.25 % and 3DXTech specifies a 120 °C, 4 h pre-dry[15][16][14]Negligible (<0.1 % EMC) — BASF states drying is not necessary, unique among the elastomers here[2]
Drying temperature & timeNot documentedNone — BASF states Ultrafuse TPS 90A arrives in a printable condition and drying is not necessary[2]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[17]Bubbling and popping at the nozzle, stringing and a rough surface[17]
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[12][17]Not applicable — the SEBS chemistry has no amide or ester linkages to take up water, and BASF specifies no drying at all[2]
Storage requirementAirtight containers with desiccant to prevent reabsorption[12]Sealed with desiccant; often kept in a dryer during the print[17]
Mechanical Properties
Tensile strength (XY)MPa68 at break (printed XY, ISO 527, 3DXTech) — above the 58 of 3DXTech's unfilled ezPC; Stratasys prints 47.6-49.4 at yield in XZ (ASTM D638)[1][18][3]Not documented
Young's modulusMPa2300 (printed XY, ISO 527); Stratasys prints 1960 in XZ and 1810-1910 in ZX (ASTM D638)[1][3]Not documented
Elongation at break%6 at break (printed XY, ISO 527), against 14 for the unfilled grade[1][18]Not documented
Flexural strengthMPa95 (printed XY, ISO 178); Stratasys prints 82.6-83.2 at break in XZ against 46.3-49.5 in ZX (ASTM D790)[1][3]Not documented
Flexural modulusMPa2310 (printed XY, ISO 178)[1]Not documented
Layer adhesion / Z tensileMPa32.5-37.9 at yield printed ZX (Stratasys, ASTM D638 on the Fortus 450mc and F900)[3]Not documented
Brittleness1–5Moderate[1]Very ductile — bends far before failing[2]
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 an ESD grade[19]89 Shore A and 29 Shore D (BASF Ultrafuse TPS 90A, ISO 7619-1)[2]
Creep resistance / sustained load1–5Excellent — holds load for years. Moulded unfilled PC was still running unbroken under 41 MPa tensile creep at room temperature when the test was stopped, and the conductive filler leaves the glass transition unchanged at 142 °C, so the creep mechanism is polycarbonate's[20][3]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[21]
Fatigue / repeated-flex resistance1–5Not documentedExcellent — living hinges viable[11]
Elasticity / flexibility1–5Rigid[1]Rubbery / highly elastic[2]
Z strength as % of XY%68-77 (Stratasys ZX against XZ tensile yield, ASTM D638)[3]Not documented
Wear resistance & frictionNot documentedAbrasion 111 mm³ (ISO 4649) — the poorest abrasion resistance in this group, well behind TPU[2]
Thermal Properties
HDT at 0.45 MPa°C143-146 printed in XY, XZ and ZX (Stratasys, ASTM D648 Method B at 66 psi); 135 moulded[3]Not documented
HDT at 1.8 MPa°C140-144 printed in XY, XZ and ZX (Stratasys, ASTM D648 Method B at 264 psi); 124 moulded[3]Not documented
Glass transition (Tg)°C143 (DSC, 3DXTech) and 142 (Stratasys, ASTM D7426)[1][3]Not documented
Melting point / Vicat°CNot documented242–249 melting (BASF Ultrafuse TPS 90A, ISO 11357-3)[2]
Continuous service temperature°C113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[16]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 conductive-filled grade[19]Not documented
Environment & Chemical
UV resistance1–5Not documentedGood — years with some colour shift; Polymaker lists UV exposure among the conditions TPU withstands[11]
Chemical resistanceWithstands oils, solvents and fuels; Polymaker rates it good against weak acids[12]Withstands industrial solvents and UV exposure (Polymaker)[11]
Water / humidity resistance in service1–5Not documentedExcellent — essentially unaffected[2]
Food contactBisphenol-A polycarbonate is not offered as food-contact filament[12]Not food safe without specific certification (Polymaker)[11]
Biodegradability / compostabilityNot biodegradable[12]Not biodegradable[11]
RecyclabilityMechanically recyclable but not accepted in household plastic collection[12]Not accepted in household plastic collection[11]
Electrical & ESD propertiesSurface resistance 10⁷–10⁹ ohm/sq, the static-dissipative band (ASTM D257), against above 10¹³ for unfilled ezPC[1][18]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[22]Low hazard — minimal VOC and particle emission; TPU was not among the nine filaments in the chamber study[22]
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[22]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[22][7]Open a window / occasional ventilation[22]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Not documented
Post-Processing
Sanding & machiningSands and machines well; the toughness means it cuts rather than chips[9]Difficult to sand or smooth; Polymaker limits post-processing to trimming or tumbling[11]
Gluing & solvent weldingCyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[9]Cyanoacrylate bonds TPU; no common solvent welds it[11]
Vapour / chemical smoothingNo practical vapour smoothing[9]No practical vapour smoothing[11]
Support material pairingPrints its own supports; 3DXTech sells a dedicated PC break-away support[9]Polymaker warns TPU supports are often very difficult to remove[11]
Solvents & Solubility
Soluble inDichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[23]Toluene dissolves SEBS at room temperature — Kraton quotes solution viscosity at 25 % mass in toluene, 25 °C.[24]
Softened or crazed byMethanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[23]Soaking in hydrocarbon solvents and oils deteriorates it; short exposures are tolerated. Resists water, acids and bases.[24]
Solvent welding & smoothing agentDichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[25]Toluene will weld it, though the joint stays soft; no workshop-safe agent, and vapour smoothing is not practical.[24]
