| Base polymer / chemistry | Bisphenol-A polycarbonate — an amorphous engineering thermoplastic[1][2] | PETG compounded with a conductive filler to bring surface resistivity into the static-dissipative range[3][4] |
| Densityg/cm³ | 1.19 (Polymaker) to 1.22 (Prusament), ISO 1183; Bambu Lab 1.20; Stratasys specific gravity 1.20 (ASTM D792)[1][5][6][7] | 1.24 (Fiberon) and 1.28 (3DXTech), ISO 1183[3][4] |
| Typical priceUSD/kg | 1 kg spools cluster near 40[6][8][9] | 1 kg-equivalent spools span 66–140; the middle of the market is about 103[8][10] |
| Price range across brandsUSD/kg | 30–92 across brands; Polymaker PolyLite 30, Bambu Lab 40, Polymaker PolyMax 52, Prusament 59, 3DXTech ezPC 64 and 3DXMAX PC 92[8][6][9][10] | 66–140 across brands; Fiberon PETG-ESD 66, 3DXSTAT ESD-PETG 140[8][10] |
| Market availability1–5 | Available from several mainstream brands[6][8][10][9] | Niche, a handful of specialist brands[8][10] |

| Typical applications | Light guides, lenses, under-bonnet automotive parts and impact-loaded housings that must hold shape above 110 °C[2][1] | Electronics fixtures, trays and jigs handled around static-sensitive components[3][4] |
| Diameter tolerance± mm | ±0.03 (Prusament PC Blend)[5] | Not documented |
| Printing Parameters | ||
| Nozzle temperature°C | 250–280 across brands; Prusament 275 ± 10, Bambu Lab 260–280, Polymaker 250–270. Polymaker's material guide gives a wider 260–310 for PC and its composites[5][6][1][2] | 250–290 (Fiberon)[3] |
| Bed temperature°C | 90–115; Prusament 110 ± 10, Bambu Lab 90–110, Polymaker 90–105[5][6][1] | 70–80 (Fiberon); 70 (3DXTech)[3][4] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive) — Polymaker specifies a 70–100 °C chamber, Bambu Lab 45–60 °C and rules out its P1P and A-series machines[1][6][11] | Open frame is fine — Fiberon specifies room-temperature chamber[3] |
| Recommended chamber temperature°C | 70–100 (Polymaker); 45–60 (Bambu Lab)[1][6] | Not documented |
| Part cooling fan | Off or very low — Polymaker specifies off, Prusament 20 % within a 0–30 % range, Bambu Lab 0–60 %[1][5][6] | Not documented |
| Bed surface & adhesion aid | Textured PEI with glue when needed (Polymaker); smooth or textured PEI (Bambu Lab)[1][12] | Textured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[13][14] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 24 at Bambu Lab's 300 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer; Polymaker allows 50–200 mm/s and its material guide advises 30–60 for layer adhesion[6][1][2][15] | 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[3][15] |
| Warping tendency1–5 | Severe — heated chamber needed[1][2][11] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[1][11] | Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[13][14] |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed[2] | Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[14] |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning[2][11] | Intermediate — dry filament and a tuned profile; resistivity depends on getting the nozzle temperature right[3] |
| Extruder requirement | All-metal hotend rated to 300 °C; Polymaker advises larger nozzles and high chamber temperatures to improve bonding[2] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[11] | Hardened steel required[3] |
| Abrasiveness1–5 | Non-abrasive[1] | Moderately abrasive — conductive carbon filler[3] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle[2] | Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-PETG, only a 65 °C pre-dry[16] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[17] | Slightly sensitive[18] |
| Hotend requirement | All-metal hot end required (Simplify3D); Polymaker advises a hot end rated above 300 °C[17][2] | No special hot-end required[18] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low — 0.25 % saturated at 25 °C / 55 % RH (Bambu Lab); Prusa measures 0.15 % after 7 days at 22 % RH. Polymaker nonetheless calls PC highly hygroscopic in service[6][5][2] | 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[13][16] |
| Equilibrium moisture content at ~50 % RH% | 0.25 saturated at 25 °C / 55 % RH (Bambu Lab); 0.15 after 7 days at 24 °C / 22 % RH (Prusa)[6][5] | 0.41 equilibrium water absorption (Fiberon PETG-ESD)[3] |
| Drying temperature & time | 80 °C for 8 h (Bambu Lab); 75 °C for 6 h (Polymaker); 70–80 °C for 6–8 h (Polymaker material guide)[6][1][2] | 65 °C for 3 h (Fiberon)[3] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[19] | Bubbling and popping at the nozzle, stringing and a rough surface[19] |
| Effect of moisture on strength | No dry-versus-conditioned figures are published. Polymaker calls PC highly hygroscopic and requires a 70–80 °C dry for 6–8 h; run wet, the loss shows as surface defects and poor layer adhesion[2][19] | 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[19] |
| Storage requirement | Airtight containers with desiccant to prevent reabsorption[2] | Sealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[19][14] |

| Flammability / UL 94 | Flammable; no UL 94 rating on standard PC, though V-0 grades exist[29][1] | Flammable; no UL 94 rating published for standard grades[30] |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors — unstabilised PC yellows and embrittles under UV[2] | Not documented |

| Dust & fibre handling hazard | Not documented | Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[3] |
| Post-Processing | ||
| Sanding & machining | Sands and machines well; the toughness means it cuts rather than chips[17] | Sands poorly — the material is tough and gums rather than powders[18] |
| Painting & finishing | Optical clarity survives printing, so transparent parts are usually left unpainted[2] | Not documented |
| Gluing & solvent welding | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[17] | Cyanoacrylate; no common solvent welds PETG cleanly[18] |

| Support material pairing | Prints its own supports; 3DXTech sells a dedicated PC break-away support[17] | Prints its own supports; Polymaker rates PolyDissolve S1 for PETG[18] |
| Dimensional accuracy & detail | Warping is the dominant accuracy limit; light transmission 89 % on PolyLite PC (GB/T 2410)[1][2] | Nozzle temperature has to be held steady — it moves surface resistivity by three orders of magnitude[3] |
| Solvents & Solubility | ||
| Soluble in | Dichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[32] | No common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[33][34] |
| Softened or crazed by | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[32] | Acetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[33] |
| Solvent welding & smoothing agent | Dichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[35] | Dichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[34] |
