| Identity & Market | ||
| Base polymer / chemistry | ABS with a flame-retardant package; 3DXTech rates the base resin UL 94 V-0[1] | Polyoxymethylene, normally the copolymer POM-C. Apium's filament grade is POM-C with antistatic additives; no unfilled POM filament was found on sale[2][3] |
| Densityg/cm³ | 1.18 (ISO 1183) — above unfilled ABS at 1.05 because of the retardant loading[1][4] | 1.41 (extruded POM-C stock)[2] |
| Typical priceUSD/kg | 1 kg-equivalent spools span 45–120; the middle of the market is about 52[5][6][7][8] | Not documented |
| Price range across brandsUSD/kg | 45–120 across brands; SUNLU 45, YXPOLYER 50, Coex 3D 52, 3DXTech 107 at 750 g pricing; the FR PC/ABS grade runs 120[5][6][7][8] | Not documented |
| Market availability1–5 | Niche, a handful of specialist brands[5] | 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[3][9][10][11] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 750 g spools[5] | Not documented |
| Typical applications | Electrical enclosures and transport interiors that must meet a flammability rating[1] | Gears, bushings, bearings, conveyor and food-machinery parts; Apium markets its POM-C ESD grade for semiconductor insulators, aerospace fasteners and sliding parts[2][3] |
| Printing Parameters | ||
| Enclosure / chamber requirement1–5 | Enclosure recommended[12] | Not documented |
| Bed surface & adhesion aid | Clean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[12][13] | Not documented |
| Warping tendency1–5 | High — enclosure needed for reliable large parts[12] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[12] | Not documented |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[14] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[12] | 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[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[12] | Not documented |
| Abrasiveness1–5 | Non-abrasive[1] | Not documented |
| Nozzle clog risk1–5 | Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its FR-ABS, only an 80 °C pre-dry[15] | Not documented |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[13] | Not documented |
| Hotend requirement | No special hot-end required[13] | Not documented |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — the ABS matrix takes up 0.51–0.65 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 80 °C, 4 h pre-dry[4][16][15] | Low (0.1-0.3 %) — extruded POM-C stock takes up 0.18 % in 24 h and 0.80 % at saturation (ASTM D570)[2] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[17] | Not documented |
| Effect of moisture on strength | Polymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[17] | Not documented |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity[17] | Not documented |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 45 at break (printed XY, ISO 527)[1] | 66.9 at break and 64.1 at yield (extruded POM-C stock, ASTM D638; converted from 9700 and 9300 psi)[2] |
| Young's modulusMPa | 1990 (printed XY, ISO 527)[1] | 2275 (extruded POM-C stock, ASTM D638; converted from 330,000 psi)[2] |

| Other impact data | Not documented | Izod 53 J/m on extruded POM-C stock, converted from 1.0 ft-lb/in[2] |
| Brittleness1–5 | Moderate — elongation at break falls to 4 % from 10 % for the unfilled grade[1][18] | Tough — absorbs impact, yields before breaking; extruded stock elongates 40 % before failing. No printed figure is published[2] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell 86 (and R120) — the source names only the R scale on extruded POM-C stock (ASTM D785)[2] |
| Creep resistance / sustained load1–5 | Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1][18] | Not documented |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve found; elongation at break falls to 4 % against 10 % for unfilled 3DXTech ABS[1][18] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Not documented |
| Wear resistance & friction | Not documented | Wear factor 65e-10 in3*min/(ft*lb*h) and a dynamic coefficient of friction of 0.21 at 40 psi and 50 fpm (ASTM D3702, extruded stock) — the properties that make acetal the default gear and bushing plastic; Apium lists good sliding properties as the reason for its grade[2][3] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 158 (extruded POM-C stock, ASTM D648 at 66 psi; converted from 316 °F)[2] |
| HDT at 1.8 MPa°C | Not documented | 110 (extruded POM-C stock, ASTM D648 at 264 psi; converted from 230 °F)[2] |
| Glass transition (Tg)°C | 105 (DSC)[1] | Not documented |
| Melting point / Vicat°C | Not documented | 165 melting (extruded POM-C stock; converted from 329 °F)[2] |

| Thermal expansion (CTE)µm/m·K | Not documented | 84.6 (extruded POM-C stock, ASTM D696; source states 4.7e-5 in/in/°F)[2] |
| Flammability / UL 94 | UL 94 V-0 at 1.5 mm, rated on the base resin rather than the printed part[1] | UL 94 HB on extruded POM-C stock[2] |
| Environment & Chemical | ||
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[19] | Good chemical resistance, particularly to bases; Apium lists resistance to bases as a headline property[2][3] |
| Water / humidity resistance in service1–5 | Not documented | Good — minor absorption; 0.80 % water at saturation (ASTM D570, extruded stock)[2] |

| Biodegradability / compostability | Not biodegradable[14] | Not documented |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[14] | 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[2][3] |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[20][12] | Not documented |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[20] | Not documented |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[20] | Not documented |
| Hazardous species emitted | Styrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[20][12] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[20][12] | Not documented |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[14] | Easy to machine — Ensinger lists machinability as a headline property of POM-C stock[2] |
| Painting & finishing | Paints readily after light abrasion[14] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[21][12] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[22][19] | Hexafluoroisopropanol dissolves it at room temperature; NMP and DMF only when hot. Laboratory reagents.[23] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[22][24] | Acids, oxidants, halogens and hot concentrated zinc chloride attack it; alcohols, ketones and esters do not.[23][22] |
| Solvent welding & smoothing agent | Acetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[25] | None — no solvent softens POM below its melting point, which is why it is bolted or heat-welded rather than glued.[23] |
