| Identity & Market | ||
| Base polymer / chemistry | Polyether block amide: rigid polyamide and flexible polyether blocks.[1] | PETG compounded with a conductive filler to bring surface resistivity into the static-dissipative range[2][3] |
| Densityg/cm³ | 1.01 g/cm³ (GB/T 1033; eSUN manufacturer data)[1] | 1.24 (Fiberon) and 1.28 (3DXTech), ISO 1183[2][3] |
| Typical priceUSD/kg | Not documented | 1 kg-equivalent spools span 66–140; the middle of the market is about 103[4][5] |
| Price range across brandsUSD/kg | Not documented | 66–140 across brands; Fiberon PETG-ESD 66, 3DXSTAT ESD-PETG 140[4][5] |
| Market availability1–5 | Not documented | Niche, a handful of specialist brands[4][5] |
| Spool sizes & diameters | 1.75 mm diameter, 1 kg spool.[6] | 1.75 mm; 0.5, 0.75, 1 and 3 kg spools[4][5] |
| Typical applications | Manufacturer applications include footwear, sports equipment and cushioning.[1] | Electronics fixtures, trays and jigs handled around static-sensitive components[2][3] |
| Printing Parameters | ||
| Nozzle temperature°C | 230–260 °C; 240 °C recommended.[1] | 250–290 (Fiberon)[2] |
| Bed temperature°C | 60–90 °C[1] | 70–80 (Fiberon); 70 (3DXTech)[2][3] |
| Enclosure / chamber requirement1–5 | Not documented | Open frame is fine — Fiberon specifies room-temperature chamber[2] |
| Part cooling fan | 10–50% fan recommended; mechanical-test specimens used 50–100%.[1] | Not documented |
| Bed surface & adhesion aid | PEI build plate[1] | Textured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[7][8] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 9 mm³/s maximum in eSUN spiral-vase test; mechanical specimens used 2 mm³/s. Linear recommendation 25–110 mm/s is a separate quantity.[1] | Fiberon rates the material to 500 mm/s, equivalent to 40 on a 0.4 mm nozzle at 0.2 mm layer — a machine-limited headline rather than a measured melt rate[2][9] |
| Bed-adhesion difficulty1–5 | Not documented | Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[7][8] |
| Stringing / oozing tendency1–5 | Not documented | Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[8] |
| Overall printing difficulty1–5 | Not documented | Intermediate — dry filament and a tuned profile; resistivity depends on getting the nozzle temperature right[2] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Not documented | Hardened steel required[2] |
| Abrasiveness1–5 | Not documented | Moderately abrasive — conductive carbon filler[2] |
| Nozzle clog risk1–5 | Not documented | Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-PETG, only a 65 °C pre-dry[10] |
| Heat-creep / jam sensitivity1–5 | Not documented | Slightly sensitive[11] |
| Hotend requirement | Not documented | No special hot-end required[11] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Not documented | Moderate (0.3–0.8 %) — the PETG matrix reaches 0.40 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 65 °C, 4 h pre-dry[7][10] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.41 equilibrium water absorption (Fiberon PETG-ESD)[2] |
| Drying temperature & time | 70–75 °C for 6–8 h; re-dry after receiving or extended exposure.[1] | 65 °C for 3 h (Fiberon)[2] |
| Symptoms when wet | Not documented | Bubbling and popping at the nozzle, stringing and a rough surface[12] |
| Effect of moisture on strength | Not documented | Polymaker groups PETG with nylon, PVA and TPU as highly hygroscopic; no dry-versus-conditioned strength figures are published for this grade and the loss shows as bubbling and poor layer adhesion[12] |
| Storage requirement | Not documented | Sealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[12][8] |

| Support material pairing | Not documented | Prints its own supports; Polymaker rates PolyDissolve S1 for PETG[11] |
| Dimensional accuracy & detail | Not documented | Nozzle temperature has to be held steady — it moves surface resistivity by three orders of magnitude[2] |
