| Identity & Market | ||
| Base polymer / chemistry | A carbon-filled compound conductive by volume rather than merely dissipative; Proto-pasta's is PLA-based, Recreus's and NinjaTek's are TPU, and add:north's Koltron G1 does not state its base polymer[1][2][3][4] | Polyphenylene sulfide — a semi-crystalline high-temperature polymer[5][6] |
| Densityg/cm³ | Not documented | 1.28 (ISO 1183, 3DXTech) and 1.33 (ISO 1183, Spectrum PPS AM230)[5][7] |
| Typical priceUSD/kg | 1 kg-equivalent spools span 90–181 for the carbon-filled grades; add:north's Koltron G1 sits far above at 796 because it is sold only in 100 and 250 g coils[8][9][10] | 1 kg-equivalent spools span 84–200; the middle of the market is about 117[11][12][13] |
| Price range across brandsUSD/kg | 90–796 across brands; Proto-pasta conductive PLA 90 at 1 kg, Recreus Conductive Filaflex 160 at 500 g, NinjaTek Eel 181 at 1 kg, add:north Koltron G1 796 at 250 g[8][2][9][10] | 84-200 across brands and diameters; IEMAI 3D 84 at 1 kg, Spectrum PPS AM230 117 at 750 g, 3DXTech ThermaX PPS 140 at 2.85 mm and 200 at 1.75 mm[11][12][13] |
| Market availability1–5 | Niche, a handful of specialist brands[8][2] | Niche, a handful of specialist brands[11][12] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.05, 0.1, 0.25, 0.5, 1 and 2 kg spools[8][2][9][10] | 1.75 and 2.85 mm; 500 g and 750 g spools[11][12] |
| Typical applications | Capacitive touch surfaces, low-current traces, EMI shielding and static-safe fixtures[1] | Chemical-plant and under-bonnet parts needing solvent resistance above 200 °C[6] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 335-345 (3DXTech printed-specimen conditions); 300-330 (Spectrum)[5][7] |
| Bed temperature°C | Not documented | 110-130 (3DXTech); 100-120 (Spectrum)[5][7] |
| Enclosure / chamber requirement1–5 | Open frame is fine[1] | Actively heated chamber required[14][15] |
| Recommended chamber temperature°C | Not documented | 60-80 actively heated (Spectrum PPS AM230)[7] |
| Bed surface & adhesion aid | Not documented | Adhesive required — Spectrum specifies Magigoo Pro HT[7] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[1] | Expert / industrial hardware only[14][15] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass acceptable; hardened steel for volume work[1] | Brass fine indefinitely for unfilled grades, but brass softens near these nozzle temperatures — hardened or plated hot ends are the norm[14] |
| Abrasiveness1–5 | Moderately abrasive — conductive carbon filler[1] | Non-abrasive when unfilled[5] |
| Nozzle clog risk1–5 | Low — Proto-pasta states the carbon-filled grade prints on standard PLA settings with no special nozzle required[1] | Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a mandatory 110 °C pre-dry before every print[16] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Not documented | Negligible (<0.1 % EMC) — Polymaker states minimal water absorption at 0.05 %[6] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.01 in 24 h on extruded stock (ASTM D570) — effectively non-absorbing[17] |
| Drying temperature & time | Not documented | At least 3 h at 90 °C in hot dry air if the filament has taken up moisture (Spectrum)[7] |
| Effect of moisture on strength | Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[18] | Little to measure — equilibrium uptake is 0.05 %; 3DXTech still specifies a 110 °C, 4 h pre-dry before printing[6][16] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | Not documented | 50 at break (printed XY, ISO 527, 3DXTech); 65 at break injection-moulded (ISO 527, Spectrum); 94 at yield on extruded stock (ASTM D638)[5][7][17] |
| Young's modulusMPa | Not documented | 2650 (printed XY, ISO 527, 3DXTech); 3650 injection-moulded (ISO 527, Spectrum); 5769 on extruded stock (ASTM D638)[5][7][17] |
| Elongation at break% | Not documented | 18 at break (printed XY, ISO 527, 3DXTech) against 2.0 injection-moulded (Spectrum) and 2.5 on extruded stock — the suppliers disagree by nearly an order of magnitude[5][7][17] |
| Flexural strengthMPa | Not documented | 52 (printed XY, ISO 178, 3DXTech); 141 on extruded stock (ASTM D790)[5][17] |
| Flexural modulusMPa | Not documented | 2540 (printed XY, ISO 178)[5] |
| Charpy impact, notchedkJ/m² | Not documented | 1.3 notched injection-moulded (ISO 179-1eA, Spectrum); unnotched 18[7] |
| Other impact data | Not documented | Izod notched 33 J/m on extruded PPS stock, converted from 0.62 ft-lb/in (ASTM D256)[17] |
| Brittleness1–5 | Brittle — snaps with little warning; carbon-black loading at conductive levels embrittles PLA[1] | Moderate[5] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell 105 (and R124) on extruded PPS stock (ASTM D785)[17] |
| Creep resistance / sustained load1–5 | Not documented | Excellent — holds load for years. Ensinger lists high creep resistance as a headline property of extruded PPS stock, and Spectrum states that rigidity, strength and creep resistance are unchanged under continuous load at high temperature[17][7] |
| Elasticity / flexibility1–5 | Rigid[1] | Rigid[5] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 90 (printed XY, ISO 75 at 0.45 MPa, 3DXTech); 129 injection-moulded (ISO 75, Spectrum); 204 on extruded stock (ASTM D648 at 66 psi)[5][7][17] |
| HDT at 1.8 MPa°C | Not documented | 107 injection-moulded (ISO 75 at 1.81 MPa, Spectrum); 104 on extruded stock (ASTM D648 at 264 psi)[7][17] |
| Melting point / Vicat°C | Not documented | 283 melting (ISO 11357, 3DXTech) and 280 on extruded stock; Vicat softening 236 at 50 N injection-moulded (ISO 306, Spectrum)[5][7][17] |
| Continuous service temperature°C | Not documented | 170 long-term service on extruded PPS stock, converted from 338 °F[17] |
| Thermal expansion (CTE)µm/m·K | Not documented | 59.4 (extruded PPS stock, 22-60 °C, ASTM D696; source states 3.3e-5 in/in/°F)[17] |
| Flammability / UL 94 | Not documented | UL 94 V-0 at 1.5 mm, rated on the base resin[5] |
| Environment & Chemical | ||
| Chemical resistance | Not documented | Outstanding — PPS resists essentially all solvents below 200 °C[6] |
| Water / humidity resistance in service1–5 | Not documented | Excellent — essentially unaffected; extruded stock takes up 0.01 % water in 24 h[17] |
| Electrical & ESD properties | Conductive rather than dissipative — Proto-pasta sells the grade as electrically conductive composite PLA[1] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[19] | 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[19] |
| Ventilation / filtration requirement1–5 | Open a window / occasional ventilation[19] | Ventilated room or enclosure recommended[19] |
| Dust & fibre handling hazard | Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Chloroform dissolves PLA-based grades, leaving the carbon black; TPU-based grades need DMF, NMP or THF. Laboratory reagents.[20][21] | None — PPS does not dissolve in any known solvent below 200 °C.[22][23] |
| Softened or crazed by | Acetone and ethyl acetate plasticise a PLA-based grade; a TPU-based grade swells in toluene, esters and alcohols.[20][21] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[23] |
| Solvent welding & smoothing agent | None — neither PLA nor TPU has a workshop-safe welding or smoothing solvent.[20][21] | None — no solvent welds or smooths PPS.[22] |
Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ.
