| Printing Parameters | ||
| Nozzle temperature°C | 250–270 (Polymaker)[1] | 250–290 (Fiberon)[3] |
| Bed temperature°C | 90–105 (Polymaker)[1] | 70–80 (Fiberon); 70 (3DXTech)[3][4] |
| Enclosure / chamber requirement1–5 | Enclosure required (passive) — Polymaker specifies a 90–100 °C chamber[1] | Open frame is fine — Fiberon specifies room-temperature chamber[3] |
| Recommended chamber temperature°C | 90–100 (Polymaker)[1] | Not documented |
| Part cooling fan | Off (Polymaker)[1] | Not documented |
| Bed surface & adhesion aid | PEI with a glue stick or a commercial adhesive[10] | Textured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[11][12] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 20 at Polymaker's 250 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer[1][13] | 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][13] |
| Warping tendency1–5 | High — enclosure needed for reliable large parts[1][14] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[10][15] | Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[11][12] |
| Stringing / oozing tendency1–5 | Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[15] | Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[12] |
| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning[1][14] | Intermediate — dry filament and a tuned profile; resistivity depends on getting the nozzle temperature right[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[14] | 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; 3DXTech lists no special nozzle concerns but a 120 °C pre-dry of 4 h or more[16] | Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-PETG, only a 65 °C pre-dry[17] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[10] | Slightly sensitive[18] |
| Hotend requirement | All-metal hot end required (Simplify3D)[10] | No special hot-end required[18] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low (0.1–0.3 %) — the PC matrix takes up 0.15–0.25 % and 3DXTech specifies a 120 °C, 4 h or more pre-dry[19][20][16] | 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[11][17] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.41 equilibrium water absorption (Fiberon PETG-ESD)[3] |
| Drying temperature & time | 75 °C for 6 h (Polymaker)[1] | 65 °C for 3 h (Fiberon)[3] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[21] | Bubbling and popping at the nozzle, stringing and a rough surface[21] |
| 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[15][21] | 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[21] |
| Storage requirement | Airtight containers with desiccant to prevent reabsorption[15] | Sealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[21][12] |

| Hardness (scale-specific)Shore A / Shore D / Rockwell | Rockwell 70 (118) — the source does not name the scales and Shore D 79 on extruded unfilled PC stock (ASTM D785, D2240); no figure is published for a PC/ABS filament[22] | Not documented |
| Creep resistance / sustained load1–5 | Good. Room-temperature tensile creep of moulded PC/ABS was still running unbroken at 30 MPa when the experiment was stopped for time; specimens failed within the test window at 39-47 MPa (ASTM D638)[23] | Below average — no ESD-grade creep test; unfilled PETG sagged from 12 to 17.1–20.4 mm over 5 days at 1.25 kg[24][25][26][27] |
| Fatigue / repeated-flex resistance1–5 | Not documented | Moderate — no ESD-grade S-N curve; unfilled printed PETG ran 79 000–193 000 cycles at 30 % of tensile strength[28] |

| HDT at 1.8 MPa°C | 106 (ISO 75 at 1.8 MPa, Polymaker); Stratasys prints 107.5 in XY and 112.0 in XZ (ASTM D648 Method B at 264 psi), against 102.9 moulded[1][5] | 72 (ISO 75, 1.8 MPa, Fiberon)[3] |

| Food contact | Bisphenol-A polycarbonate is not offered as food-contact filament[15] | Not certified for food contact as filament[12] |
| Biodegradability / compostability | Not biodegradable[15] | Not biodegradable[12] |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[15] | Not accepted in household plastic collection[12] |
| Electrical & ESD properties | Not documented | 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[3][4] |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[30] | Moderate — measurable VOCs and UFPs, ventilation advised[30] |
| Ultrafine-particle emission rateparticles/min | ≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[30] | 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[10] | Sands poorly — the material is tough and gums rather than powders[18] |
| Gluing & solvent welding | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[10] | Cyanoacrylate; no common solvent welds PETG cleanly[18] |
| Vapour / chemical smoothing | Acetone attacks the ABS phase, so surface smoothing is partial rather than full[1] | No practical vapour smoothing[18] |
| Support material pairing | Prints its own supports; 3DXTech sells a dedicated PC break-away support[10] | Prints its own supports; Polymaker rates PolyDissolve S1 for PETG[18] |
| Dimensional accuracy & detail | Not documented | Nozzle temperature has to be held steady — it moves surface resistivity by three orders of magnitude[3] |
| Solvents & Solubility | ||
| Soluble in | Dichloromethane and chloroform dissolve the PC phase; acetone, MEK and THF dissolve the ABS phase.[31][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 | Petrol, esters, ether and 1 % alkali stress-crack the PC phase; aromatics and esters soften the ABS phase.[31][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 | Acetone attacks only the ABS phase, so smoothing is partial; a dichloromethane cement welds the whole section.[1][35] | Dichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[34] |
