| Market snapshot | ||
| Listing priceUSD/kg; dated snapshots | $170.36/kg median; $89.99–$796.00/kg across 4 dated product listings | $42.49/kg median; $26.00–$79.98/kg across 4 dated product listings |
| 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] | Break-away support compounds matched to a specific model material — Polymaker sells separate grades for PLA and for PA12[5][6] |
| Densityg/cm³ | Not documented | 1.22 (PolySupport for PLA) and 1.29 (PolySupport for PA12), ISO 1183[5][6] |
| 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[7][8][9] | 1 kg-equivalent spools span 26–80; the middle of the market is about 45[10][11][12] |
| 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[7][2][8][9] | 26–80 across brands and grades; IEMAI 3D E-REMOVE 26, Polymaker PolySupport for PLA 40 at 750 g, YXPOLYER 45, PolySupport for PA12 80 at 500 g[10][11][12] |
| Market availability1–5 | Niche, a handful of specialist brands[7][2] | Available from several mainstream brands[10][13] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.05, 0.1, 0.25, 0.5, 1 and 2 kg spools[7][2][8][9] | 1.75 and 2.85 mm; 0.5 and 0.75 kg spools[10] |
| Typical applications | Capacitive touch surfaces, low-current traces, EMI shielding and static-safe fixtures[1] | Support that peels off by hand, avoiding the moisture handling and dissolution time that soluble supports demand[5] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 220–230 (PolySupport for PLA)[5] |
| Bed temperature°C | Not documented | 25–60 (PolySupport for PLA)[5] |
| Enclosure / chamber requirement1–5 | Open frame is fine[1] | Open frame is fine[5] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | 4–12 at Polymaker's 50–150 mm/s on a 0.4 mm nozzle at 0.2 mm layer[5] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[1] | Easy — minor profile tuning[5] |
| Extruder requirement | Not documented | A second extruder or a tool changer[5] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass acceptable; hardened steel for volume work[1] | Brass fine indefinitely[5] |
| Abrasiveness1–5 | Moderately abrasive — conductive carbon filler[1] | Non-abrasive[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; Polymaker specifies a 55 °C dry for the PLA grade and warns brass nozzle life falls to about 9 h on the PA12 grade[5][6] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Not documented | Moderate — 0.64 % equilibrium water absorption (PolySupport for PLA)[5] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.64 equilibrium water absorption (Polymaker PolySupport for PLA)[5] |
| 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[14] | Not a structural material; no dry-versus-conditioned data is published[14] |
| Mechanical Properties | ||
| Brittleness1–5 | Brittle — snaps with little warning; carbon-black loading at conductive levels embrittles PLA[1] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Not documented |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 43 (ISO 75, 0.45 MPa, PolySupport for PA12). Polymaker's sheet prints a higher figure at the higher load, which is physically inverted; treat both HDT numbers as approximate[6] |
| HDT at 1.8 MPa°C | Not documented | 53 (ISO 75, 1.8 MPa, PolySupport for PA12) — printed above the 0.45 MPa figure on Polymaker's own sheet, which cannot be right; treat both as approximate[6] |
| Melting point / Vicat°C | Not documented | Vicat 171 (PolySupport for PA12, ISO 306)[6] |
| Environment & Chemical | ||
| Electrical & ESD properties | Conductive rather than dissipative — Proto-pasta sells the grade as electrically conductive composite PLA[1] | Surface resistance above 10^13 ohm/sq (ASTM D257, THERMAX HTS2 and MTS1)[15][16] |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[17] | Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[17] |
| Ventilation / filtration requirement1–5 | Open a window / occasional ventilation[17] | Open a window / occasional ventilation[17] |
| Dust & fibre handling hazard | Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1] | Not documented |
| Post-Processing | ||
| Support material pairing | Not documented | This is the support material. Polymaker publishes an adhesion matrix per model material, from very good to unusable, because break-away supports only work against the polymer they were matched to[5][6] |
| Solvents & Solubility | ||
| Soluble in | Chloroform dissolves PLA-based grades, leaving the carbon black; TPU-based grades need DMF, NMP or THF. Laboratory reagents.[18][19] | None — break-away support is removed mechanically; 3DXTech lists no water or solvent route for it.[20] |
| Softened or crazed by | Acetone and ethyl acetate plasticise a PLA-based grade; a TPU-based grade swells in toluene, esters and alcohols.[18][19] | Not documented |
| Solvent welding & smoothing agent | None — neither PLA nor TPU has a workshop-safe welding or smoothing solvent.[18][19] | None — there is no solvent to weld or smooth with.[20] |
Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
