Printing Parameters
Nozzle temperature°CNot documented250–290 (Fiberon)[2]
Bed temperature°CNot documented70–80 (Fiberon); 70 (3DXTech)[2][3]
Enclosure / chamber requirement1–5Enclosure required (passive)[7][8]Open frame is fine — Fiberon specifies room-temperature chamber[2]
Bed surface & adhesion aidPEI with a glue stick or a commercial adhesive[9]Textured PEI, satin or powder-coated sheets; on smooth PEI a glue stick acts as a release agent[10][11]
Maximum volumetric flow (mm³/s; see test conditions)mm³/sNot documentedFiberon 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][12]
Warping tendency1–5Severe — heated chamber needed[7][8]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[9][13]Needs the right surface or a thin adhesive — the problem is releasing the part, not sticking it[10][11]
Stringing / oozing tendency1–5Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[13]Moderate — retraction tuning needed; Polymaker names stringing as PETG's common quirk[11]
Overall printing difficulty1–5Advanced — enclosure, hardware upgrades, tuning[7]Intermediate — dry filament and a tuned profile; resistivity depends on getting the nozzle temperature right[2]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[1]Hardened steel required[2]
Abrasiveness1–5Moderately abrasive — conductive carbon filler[1]Moderately abrasive — conductive carbon filler[2]
Nozzle clog risk1–5Moderate — needs dry filament and a clean nozzle; 3DXTech lists no special nozzle concerns but a 120 °C pre-dry[14]Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its ESD-PETG, only a 65 °C pre-dry[15]
Heat-creep / jam sensitivity1–5Slightly sensitive[9]Slightly sensitive[16]
Hotend requirementAll-metal hot end required (Simplify3D)[9]No special hot-end required[16]
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Low (0.1–0.3 %) — the PC matrix takes up 0.15–0.25 % and 3DXTech specifies a 120 °C, 4 h pre-dry[17][18][14]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[10][15]
Equilibrium moisture content at ~50 % RH%Not documented0.41 equilibrium water absorption (Fiberon PETG-ESD)[2]
Drying temperature & timeNot documented65 °C for 3 h (Fiberon)[2]
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[19]Bubbling and popping at the nozzle, stringing and a rough surface[19]
Effect of moisture on strengthNo 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[13][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 requirementAirtight containers with desiccant to prevent reabsorption[13]Sealed with desiccant; Polymaker groups PETG with the highly hygroscopic materials[19][11]
Mechanical Properties
Tensile strength (XY)MPa68 at break (printed XY, ISO 527, 3DXTech) — above the 58 of 3DXTech's unfilled ezPC; Stratasys prints 47.6-49.4 at yield in XZ (ASTM D638)[1][20][4]36.1 ± 0.9 printed XY, ISO 527 (Fiberon); 3DXTech quotes 50 at break[2][3]

Brittleness1–5Moderate[1]Moderate[2]

Creep resistance / sustained load1–5Excellent — holds load for years. Moulded unfilled PC was still running unbroken under 41 MPa tensile creep at room temperature when the test was stopped, and the conductive filler leaves the glass transition unchanged at 142 °C, so the creep mechanism is polycarbonate's[22][4]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[23][24][25][26]

Health & Safety
Fume toxicity1–5Moderate — measurable VOCs and UFPs, ventilation advised[29]Moderate — measurable VOCs and UFPs, ventilation advised[29]
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[29]Not documented
Ventilation / filtration requirement1–5Ventilated room or enclosure recommended[29][7]Open a window / occasional ventilation[29]
Dust & fibre handling hazardConductive carbon filler is bound in the matrix; avoid inhaling sanding dust[1]Conductive carbon filler is bound in the matrix; avoid inhaling sanding dust[2]
Post-Processing
Sanding & machiningSands and machines well; the toughness means it cuts rather than chips[9]Sands poorly — the material is tough and gums rather than powders[16]
Gluing & solvent weldingCyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[9]Cyanoacrylate; no common solvent welds PETG cleanly[16]
Vapour / chemical smoothingNo practical vapour smoothing[9]No practical vapour smoothing[16]
Support material pairingPrints its own supports; 3DXTech sells a dedicated PC break-away support[9]Prints its own supports; Polymaker rates PolyDissolve S1 for PETG[16]
Dimensional accuracy & detailNot documentedNozzle temperature has to be held steady — it moves surface resistivity by three orders of magnitude[2]
Solvents & Solubility
Soluble inDichloromethane, chloroform, DMF and dioxane dissolve it outright (Covestro, 6 days at 23 °C). Laboratory reagents.[30]No common workshop solvent; 1,2-dichloroethane destroys it inside a week and dichloromethane — a carcinogen — dissolves the surface.[31][32]
Softened or crazed byMethanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[30]Acetone (+16 % weight over 1 year at 23 °C), ethyl acetate, toluene and DMF swell and soften it; methanol crazes it.[31]
Solvent welding & smoothing agentDichloromethane cement welds PC — 16.5 MPa lap shear at one week (IPS Weld-On 3). A controlled carcinogen.[33]Dichloromethane brushed on is the only agent that smooths PETG — a controlled carcinogen, not workshop stock.[32]
