| Identity & Market | ||
| Base polymer / chemistry | PETG compounded with a conductive filler to bring surface resistivity into the static-dissipative range[1][2] | Poly(lactic acid), a thermoplastic aliphatic polyester from fermented plant starch[3][4] |
| Densityg/cm³ | 1.24 (Fiberon) and 1.28 (3DXTech), ISO 1183[1][2] | 1.17–1.24 (ISO 1183)[3][5][4] |
| Typical priceUSD/kg | 1 kg-equivalent spools span 66–140; the middle of the market is about 103[6][7] | Mainstream 1 kg spools cluster near 20[8][9][10] |
| Price range across brandsUSD/kg | 66–140 across brands; Fiberon PETG-ESD 66, 3DXSTAT ESD-PETG 140[6][7] | 10–33 across brands; budget house brands 10–14, premium European 26–33[11][12][13][14] |
| Market availability1–5 | Niche, a handful of specialist brands[6][7] | Ubiquitous, every brand and retailer[15][16] |
| Spool sizes & diameters | 1.75 mm; 0.5, 0.75, 1 and 3 kg spools[6][7] | 1.75 and 2.85 mm; 0.75, 0.85, 1 and 1.1 kg spools plus spool-less refills[8][17][18][13][19] |
| Typical applications | Electronics fixtures, trays and jigs handled around static-sensitive components[1][2] | Concept models, functional prototypes, low-wear toys, jigs used at room temperature[20] |
| Diameter tolerance± mm | Not documented | ±0.02 (Prusament) to ±0.03 (Bambu Lab, Prusa Research standard)[3][8][21] |
| Printing Parameters | ||
| Nozzle temperature°C | 250–290 (Fiberon)[1] | 190–230; Prusament specifies 210 ± 10[3][5][4] |
| Bed temperature°C | 70–80 (Fiberon); 70 (3DXTech)[1][2] | 25–60; Prusament 40–60, Bambu Lab 35–45[3][5][4] |
| Enclosure / chamber requirement1–5 | Open frame is fine — Fiberon specifies room-temperature chamber[1] | Open frame is fine[5][15] |
| Part cooling fan | Not documented | 100 % from the second layer; reduce on the first one or two layers for bed adhesion[3][16] |
| Bed surface & adhesion aid | Textured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[22][23] | Smooth or textured PEI, glass or painter's tape; glue stick only where release is a problem[5][24][16] |
| 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][25] | 12–20 (PrusaSlicer max volumetric speed guidance for PLA)[25] |
| Warping tendency1–5 | Not documented | None[26][15] |
| Bed-adhesion difficulty1–5 | Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[22][23] | Sticks to anything — glue only needed on smooth PEI[5][4][16] |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[23] | Slight — 1–3 mm retraction handles it; oozing rises with nozzle temperature[5][16][27] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile; resistivity depends on getting the nozzle temperature right[1] | Beginner — prints on any machine out of the box[15][16] |
| Extruder requirement | Not documented | Any extruder; Bowden and direct drive both fine, no hardware upgrades[15] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[1] | Brass fine indefinitely[15] |
| Abrasiveness1–5 | Moderately abrasive — conductive carbon filler[1] | Non-abrasive[26][15] |
| 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[28] | Very low[15][16] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[29] | Moderate — good heatbreak cooling needed; softens below 60 °C so it deforms in a warm cold zone[24][30] |
| Hotend requirement | No special hot-end required[29] | Any standard hotend; PTFE-lined is fine at PLA temperatures[15] |
| Other hardware wear | Not documented | None — brass nozzles and standard drive gears are unaffected[26][15] |
| 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[22][28] | Moderate — 0.40–0.51 % saturated at 23–25 °C and 55–70 % RH[4][5][31] |
| Equilibrium moisture content at ~50 % RH% | 0.41 equilibrium water absorption (Fiberon PETG-ESD)[1] | 0.43 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 equilibrium (Polymaker)[4][5] |
| Drying temperature & time | 65 °C for 3 h (Fiberon)[1] | 50–55 °C for 6–8 h in a forced-air dryer; 45 °C for 12 h in the Bambu Lab AMS HT[5][4][30] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[32] | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[32] |
| 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[32] | Polymaker rates PLA low-sensitivity — it absorbs moisture slowly and the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[32] |
| Storage requirement | Sealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[32][23] | Sealed with desiccant below 20 % RH; shelf life at ambient is long[4][16] |

| Fatigue / repeated-flex resistance1–5 | Moderate — no ESD-grade S-N curve; unfilled printed PETG ran 79 000–193 000 cycles at 30 % of tensile strength[43] | Poor — 38 000–49 000 cycles at 30 % of tensile strength, against 79 000–193 000 for PETG (printed, R = 0.2, 7 Hz)[43][24] |
| Elasticity / flexibility1–5 | Slightly flexible in thin sections[1] | Rigid[26] |
| Z strength as % of XY% | 57 (Fiberon, printed Z against XY tensile)[1] | 77–89 on TDS specimens; ≈44 on My Tech Fun 4×4 mm bars[5][4][34] |

| Melting point / Vicat°C | Amorphous — no melting point; Vicat 86 (Fiberon, ISO 306)[1] | 145–160 peak melt (Prusament, ISO 11357); 150 and 160 by DSC (PolyLite, Bambu Lab); Vicat 57–63 (ISO 306)[20][5][4] |
| Continuous service temperature°C | Not documented | 50–55 — loaded bars begin to move at this temperature[26][34] |
| Annealing response | Not documented | Bambu Lab conditions specimens at 55 °C for 8 h; annealing at 50–60 °C for 6–12 h raises crystallinity but can warp parts[4][44] |
| Thermal expansion (CTE)µm/m·K | Not documented | 96 ± 5 at 0° and 99 ± 5 at 90° raster (printed PLA, fibre Bragg grating, 25–50 °C)[45] |
| Flammability / UL 94 | Flammable; no UL 94 rating published for standard grades[46] | Flammable; no UL 94 rating published by the major brands[4][5] |
| Environment & Chemical | ||

| Chemical resistance | Withstands acids, alkalis, oils and UV exposure[23] | Good against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[5][24] |
| Water / humidity resistance in service1–5 | Not documented | Good — insoluble in water, absorbs 0.4–0.5 % at equilibrium[4][47] |
| Food contact | Not certified for food contact as filament[23] | Base resin is food-contact grade and EN 71-3 certified by some brands, but printed layer grooves harbour bacteria; Prusa advises against food use[24][47] |
| Biodegradability / compostability | Not biodegradable[23] | Industrially compostable only — needs sustained 55 °C and specific microbial conditions; not home compostable[47][24][4] |
| Recyclability | Not accepted in household plastic collection[23] | Mechanically recyclable; not accepted in household plastic collection, so brand take-back schemes are the practical route[47] |
| Electrical & ESD properties | Surface resistivity falls with nozzle temperature: 7.0×10⁶–1.6×10⁷ ohm at 250 °C, 3.2×10⁵–4.7×10⁵ at 270 °C and below 1×10⁴ at 290 °C (Fiberon); 3DXTech quotes 10⁷–10⁹ ohm/sq[1][2] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[48] | Low hazard — minimal VOC and particle emission[48] |
| VOC emission rateµg/min | Not documented | 4–5 lactide, the dominant VOC (chamber study, three printers)[48] |
| Ultrafine-particle emission rateparticles/min | Not documented | ≈1 × 10⁸ median across three printers; only laywood ≈8 × 10⁷ and laybrick ≈6 × 10⁷ were lower[48] |

| 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[29] | Wet sanding — dry sanding heats the surface by friction and smears it[20][24] |
| Gluing & solvent welding | Cyanoacrylate; no common solvent welds PETG cleanly[29] | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone, depending on additives and colour[24][21] |
| Vapour / chemical smoothing | No practical vapour smoothing[29] | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[24] |
| Support material pairing | Prints its own supports; Polymaker rates PolyDissolve S1 for PETG[29] | PolySupport and PolyDissolve S1 (Polymaker); Support for PLA (Bambu Lab)[5][4] |
| Dimensional accuracy & detail | Nozzle temperature has to be held steady — it moves surface resistivity by three orders of magnitude[1] | Good — low shrinkage and features under 0.2 mm resolve; 55° overhangs and 30 mm bridges[26][4][16] |
| Solvents & Solubility | ||
| Soluble in | No common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[49][50] | Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[51] |
| 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.[49] | Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[51][50] |
| Solvent welding & smoothing agent | Dichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[50] | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[52][50] |
