| Identity & Market | ||
| Base polymer / chemistry | Polycarbonate/ABS alloy — PC stiffness and heat resistance with ABS processability[1][2] | Polyoxymethylene, normally the copolymer POM-C. Apium's filament grade is POM-C with antistatic additives; no unfilled POM filament was found on sale[3][4] |
| Densityg/cm³ | 1.10 (Polymaker) and 1.24 (3DXTech FR grade), ISO 1183; Stratasys specific gravity 1.10 (ASTM D792)[1][2][5] | 1.41 (extruded POM-C stock)[3] |
| Typical priceUSD/kg | 1 kg spools cluster near 50[6][7] | Not documented |
| Price range across brandsUSD/kg | 35–84 across brands; Reli3D 35, SUNLU 46, Polymaker 50, 3DXMAX 84[6][7][8][9] | Not documented |
| Market availability1–5 | Available from several mainstream brands[6][7] | Special order, 1-2 makers worldwide — Apium sells a POM-C ESD filament through its own shop and states its printers are the only ones able to process POM-C; no POM filament appears in the 3DJAKE or igo3d product sitemaps, at MatterHackers or at Printed Solid[4][10][11][12] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.5 and 1 kg spools[6][7] | Not documented |
| Typical applications | Automotive interior and electronics housings that need PC heat resistance without PC's warping[1] | Gears, bushings, bearings, conveyor and food-machinery parts; Apium markets its POM-C ESD grade for semiconductor insulators, aerospace fasteners and sliding parts[3][4] |

| Part cooling fan | Off (Polymaker)[1] | Not documented |
| Bed surface & adhesion aid | PEI with a glue stick or a commercial adhesive[13] | Not documented |
| 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][14] | Not documented |

| Overall printing difficulty1–5 | Advanced — enclosure, hardware upgrades, tuning[1][15] | Not documented |
| Extruder requirement | Not documented | Apium states that the adaptive heating system on its industrial machines is what makes POM-C printable, and that no other 3D printer can process it[4] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[15] | Not documented |
| Abrasiveness1–5 | Non-abrasive[1] | Not documented |

| Heat-creep / jam sensitivity1–5 | Slightly sensitive[13] | Not documented |
| Hotend requirement | All-metal hot end required (Simplify3D)[13] | Not documented |
| 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[18][19][17] | Low (0.1-0.3 %) — extruded POM-C stock takes up 0.18 % in 24 h and 0.80 % at saturation (ASTM D570)[3] |
| Drying temperature & time | 75 °C for 6 h (Polymaker)[1] | Not documented |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[20] | Not documented |
| 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[16][20] | Not documented |
| Storage requirement | Airtight containers with desiccant to prevent reabsorption[16] | Not documented |

| 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[21] | Rockwell 86 (and R120) — the source names only the R scale on extruded POM-C stock (ASTM D785)[3] |
| 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)[22] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Not documented |
| Z strength as % of XY% | 75-86 (Stratasys ZX against XZ tensile at break, ASTM D638) against 57 (Polymaker, printed Z against XY tensile)[1][5] | Not documented |

| Thermal Properties | ||
| HDT at 0.45 MPa°C | 112 (ISO 75 at 0.45 MPa, Polymaker); Stratasys prints 117.9 in XY and 126.1 in XZ (ASTM D648 Method B at 66 psi), against 125.0 moulded[1][5] | 158 (extruded POM-C stock, ASTM D648 at 66 psi; converted from 316 °F)[3] |

| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[16] | Not documented |

| Water / humidity resistance in service1–5 | Not documented | Good — minor absorption; 0.80 % water at saturation (ASTM D570, extruded stock)[3] |
| Food contact | Bisphenol-A polycarbonate is not offered as food-contact filament[16] | Not documented |

| Electrical & ESD properties | Not documented | Volume resistance 1e14 ohm-cm, dielectric strength 500 V/mil and dielectric constant 3.7 at 60 Hz on extruded stock (ASTM D257, D149, D150); Apium's filament grade adds antistatic agents[3][4] |
| Health & Safety | ||
| Fume toxicity1–5 | Moderate — measurable VOCs and UFPs, ventilation advised[23] | Not documented |
| 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[23] | Not documented |
| Ventilation / filtration requirement1–5 | Ventilated room or enclosure recommended[23][15] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands and machines well; the toughness means it cuts rather than chips[13] | Easy to machine — Ensinger lists machinability as a headline property of POM-C stock[3] |
| Gluing & solvent welding | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[13] | Not documented |
| Vapour / chemical smoothing | Acetone attacks the ABS phase, so surface smoothing is partial rather than full[1] | Not documented |
| Support material pairing | Prints its own supports; 3DXTech sells a dedicated PC break-away support[13] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Dichloromethane and chloroform dissolve the PC phase; acetone, MEK and THF dissolve the ABS phase.[24][25] | Hexafluoroisopropanol dissolves it at room temperature; NMP and DMF only when hot. Laboratory reagents.[26] |
| Softened or crazed by | Petrol, esters, ether and 1 % alkali stress-crack the PC phase; aromatics and esters soften the ABS phase.[24][25] | Acids, oxidants, halogens and hot concentrated zinc chloride attack it; alcohols, ketones and esters do not.[26][25] |
| Solvent welding & smoothing agent | Acetone attacks only the ABS phase, so smoothing is partial; a dichloromethane cement welds the whole section.[1][27] | None — no solvent softens POM below its melting point, which is why it is bolted or heat-welded rather than glued.[26] |
