Identity & Market
Base polymer / chemistryCarbon-filled polyamide compounded to a static-dissipative resistivity — Polymaker's grade uses a PA612 matrix[1]Styrene-ethylene-butadiene-styrene thermoplastic elastomer — a styrenic rubber, not a polyurethane[2]
Densityg/cm³1.10 (ISO 1183)[1]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 130[3]1 kg-equivalent spools cluster near 77[4]
Price range across brandsUSD/kg130 at Polymaker's 0.5 kg pricing[3]77 for the Recreus 600 g spool; Proto-pasta only lists a 50 g coil, which prices at 120[4][5]
Market availability1–5Special order, 1–2 makers worldwide[3]Niche, a handful of specialist brands[2][5][4]
Spool sizes & diameters1.75 mm; 0.5 kg spools[3]1.75 and 2.85 mm; 0.05 and 0.6 kg spools[2][4]
Typical applicationsElectronics jigs and trays that also need nylon toughness and heat resistance[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)[6]Open frame is fine[2]
Bed surface & adhesion aidPEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[7][6]PEI sheet or painter's tape; Polymaker warns TPU can over-stick and advises a glue stick as a release agent[8][9]
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]
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[7]Not documented
Stringing / oozing tendency1–5Moderate — retraction tuning needed[6]Not documented
Overall printing difficulty1–5Expert / industrial hardware only[6][10]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 — Polymaker measures brass nozzle life at about 9 h on PA612-ESD and recommends hardened steel or ruby[1]Brass fine indefinitely[11]
Abrasiveness1–5Highly abrasive — carbon-filled nylon composite; Polymaker puts brass nozzle life at roughly 9 h on PA612-ESD[1]Non-abrasive[11]
Nozzle clog risk1–5High — jams from moisture, heat creep or particles[10]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[8][2]
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed[7]Not documented
Hotend requirementMay require an all-metal hot end (Simplify3D)[7]No special hot-end required, but a direct-drive extruder is (Simplify3D)[8]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5High (0.8–2 %) — the PA612 matrix sits between PA6 and PA12[12][13]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 wetNot documentedBubbling and popping at the nozzle, stringing and a rough surface[10]
Effect of moisture on strengthPolymaker publishes dry and wet printed blocks for PA612-ESD itself: at 4.64 % moisture tensile falls 84.3 → 73.6 MPa and modulus 4294 → 3731 MPa[1][13]Not applicable — the SEBS chemistry has no amide or ester linkages to take up water, and BASF specifies no drying at all[2]
Storage requirementSealed below 20 % RH with desiccant[10]Sealed with desiccant; often kept in a dryer during the print[10]
Hydrolysis at melt temperaturePolymaker specifies an 80–100 °C dry and storage below 20 % RH; no molecular-weight loss figure is published, and the wet data it does publish is conditioning rather than melt hydrolysis[14][15]Not documented
Mechanical Properties
Tensile strength (XY)MPa84.3 ± 2.3 printed XY dry (annealed 100 °C/16 h), 73.6 ± 2.3 conditioned to 4.64 % moisture, ISO 527[1]Not documented
Young's modulusMPa4293.7 ± 116.4 printed XY dry and 3730.8 ± 156.2 conditioned, ISO 527[1]Not documented
Elongation at break%3.0 ± 0.1 printed XY dry and 4.2 ± 0.4 conditioned, ISO 527[1]Not documented
Charpy impact, notchedkJ/m²5.9 ± 0.4 printed XY dry and 4.9 ± 0.3 conditioned, ISO 179 notched[1]Not documented
Other impact dataCharpy unnotched 24.1 ± 2.4 printed XY and 4.5 ± 0.2 printed Z (ISO 179)[1]Not documented
Layer adhesion / Z tensileMPa21.5 ± 2.7 printed Z dry — only a quarter of XY, the most anisotropic nylon composite here; 19.2 ± 1.6 conditioned[1]Not documented
Brittleness1–5Brittle — snaps with little warning; elongation 3.0 % in XY and 1.4 % in Z[1]Very ductile — bends far before failing[2]
Hardness (scale-specific)Shore A / Shore D / RockwellRockwell M88 / R117 on extruded PA66-GF30 stock (ASTM D785); no figure is published for a conductive carbon-filled nylon filament[16]89 Shore A and 29 Shore D (BASF Ultrafuse TPS 90A, ISO 7619-1)[2]
Creep resistance / sustained load1–5Good. Ensinger rates its PA66-CF30 compound for sustained static and dynamic load at 110 °C continuous service; the PA612 matrix here still takes up 4.64 % moisture at conditioning, which softens it[17][1]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[18]
Fatigue / repeated-flex resistance1–5Good. Ensinger states carbon-filled PA66 compounds have improved fatigue strength in tension, flexure and compression[17]Excellent — living hinges viable[9]
Elasticity / flexibility1–5Rigid[1]Rubbery / highly elastic[2]
Z strength as % of XY%26 (printed Z against XY tensile)[1]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°C157.0 (ISO 75, 0.45 MPa)[1]Not documented
HDT at 1.8 MPa°C125.4 (ISO 75, 1.8 MPa)[1]Not documented
Glass transition (Tg)°C41.8 (DSC)[1]Not documented
Melting point / Vicat°C187.3 melting (DSC); Vicat 190.0 (ISO 306)[1]242–249 melting (BASF Ultrafuse TPS 90A, ISO 11357-3)[2]
Flammability / UL 94Flammable; no UL 94 rating published for the grades surveyed[14]Not documented
Environment & Chemical
UV resistance1–5Months outdoors before embrittlement — unstabilised polyamide yellows under UV[6]Good — years with some colour shift; Polymaker lists UV exposure among the conditions TPU withstands[9]
Chemical resistanceWithstands oils, fuels and alkalis[6]Withstands industrial solvents and UV exposure (Polymaker)[9]
Water / humidity resistance in service1–5Not documentedExcellent — essentially unaffected[2]
Food contactNot food-contact certified as filament[6]Not food safe without specific certification (Polymaker)[9]
Biodegradability / compostabilityNot biodegradable[6]Not biodegradable[9]
RecyclabilityNot accepted in household plastic collection[6]Not accepted in household plastic collection[9]
Electrical & ESD propertiesStatic-dissipative — the reason the grade exists; Polymaker's insulating nylon composites sit above 10¹² ohm by contrast[1][12]Not documented
Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[19]Low hazard — minimal VOC and particle emission; TPU was not among the nine filaments in the chamber study[19]
VOC emission rateµg/minUp to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[19]Not documented
Ultrafine-particle emission rateparticles/min≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[19]Not documented
Hazardous species emittedCaprolactam, at up to 180 µg/min from nylon filament[19]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[19]Open a window / occasional ventilation[19]
Dust & fibre handling hazardFibre is bound in the matrix; sanding dust should not be inhaled[14]Not documented
Post-Processing
Sanding & machiningSands poorly — gums rather than powders[7]Difficult to sand or smooth; Polymaker limits post-processing to trimming or tumbling[9]
Gluing & solvent weldingCyanoacrylate; no common solvent welds polyamide[7]Cyanoacrylate bonds TPU; no common solvent welds it[9]
Vapour / chemical smoothingNo practical vapour smoothing[7]No practical vapour smoothing[9]
Support material pairingNot documentedPolymaker warns TPU supports are often very difficult to remove[9]
Solvents & Solubility
Soluble inFormic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[20]Toluene dissolves SEBS at room temperature — Kraton quotes solution viscosity at 25 % mass in toluene, 25 °C.[21]
Softened or crazed byZinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[20]Soaking in hydrocarbon solvents and oils deteriorates it; short exposures are tolerated. Resists water, acids and bases.[21]
Solvent welding & smoothing agentNone — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[20]Toluene will weld it, though the joint stays soft; no workshop-safe agent, and vapour smoothing is not practical.[21]
