| Identity & Market | ||
| Base polymer / chemistry | PETG compounded with a conductive filler to bring surface resistivity into the static-dissipative range[1][2] | Poly(methyl methacrylate) — acrylic, sold for 3D printing as a transparent glass substitute[3] |
| Densityg/cm³ | 1.24 (Fiberon) and 1.28 (3DXTech), ISO 1183[1][2] | Not documented |
| Typical priceUSD/kg | 1 kg-equivalent spools span 66–140; the middle of the market is about 103[4][5] | 1 kg spools cluster near 50[6] |
| Price range across brandsUSD/kg | 66–140 across brands; Fiberon PETG-ESD 66, 3DXSTAT ESD-PETG 140[4][5] | 50 at Push Plastic's 1 kg listing; 3 kg spools run the same per kilogram[6] |
| Market availability1–5 | Niche, a handful of specialist brands[4][5] | Special order, 1–2 makers worldwide[6] |
| Spool sizes & diameters | 1.75 mm; 0.5, 0.75, 1 and 3 kg spools[4][5] | 1.75 and 2.85 mm; 1 and 3 kg spools[6] |
| Typical applications | Electronics fixtures, trays and jigs handled around static-sensitive components[1][2] | Transparent covers and light guides where PC's yellowing or cost rules it out[3] |
| Printing Parameters | ||
| Nozzle temperature°C | 250–290 (Fiberon)[1] | Not documented |
| Bed temperature°C | 70–80 (Fiberon); 70 (3DXTech)[1][2] | Not documented |
| Enclosure / chamber requirement1–5 | Open frame is fine — Fiberon specifies room-temperature chamber[1] | Not documented |
| Bed surface & adhesion aid | Textured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[7][8] | Not documented |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 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[1][9] | Not documented |
| Bed-adhesion difficulty1–5 | Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[7][8] | Not documented |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[8] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile; resistivity depends on getting the nozzle temperature right[1] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[1] | Not documented |
| Abrasiveness1–5 | Moderately abrasive — conductive carbon filler[1] | Not documented |
| Nozzle clog risk1–5 | Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-PETG, only a 65 °C pre-dry[10] | Not documented |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[11] | Not documented |
| Hotend requirement | No special hot-end required[11] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | 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] | Not documented |
| Equilibrium moisture content at ~50 % RH% | 0.41 equilibrium water absorption (Fiberon PETG-ESD)[1] | Not documented |
| Drying temperature & time | 65 °C for 3 h (Fiberon)[1] | Not documented |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[12] | Not documented |
| Effect of moisture on strength | 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] | Not documented |
| Storage requirement | Sealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[12][8] | Not documented |

| Dust & fibre handling hazard | Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands poorly — the material is tough and gums rather than powders[11] | Not documented |
| Gluing & solvent welding | Cyanoacrylate; no common solvent welds PETG cleanly[11] | Not documented |

| Dimensional accuracy & detail | Nozzle temperature has to be held steady — it moves surface resistivity by three orders of magnitude[1] | Not documented |
| Solvents & Solubility | ||
| Soluble in | No common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[20][21] | Acetone, MEK, ethyl and butyl acetate, THF, chloroform and carbon tetrachloride dissolve it; the last two are laboratory reagents.[22] |
| Softened or crazed by | Acetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[20] | Alcohols, aliphatic hydrocarbons, oils and phthalate plasticisers craze it, and the threshold falls as stress rises.[22] |
| Solvent welding & smoothing agent | Dichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[21] | Dichloromethane acrylic cement (IPS Weld-On 3): 2–5 min soak, 17.2 MPa lap shear at one week. Controlled carcinogen.[23] |
