Identity & Market
Base polymer / chemistryAcrylonitrile butadiene styrene — a styrenic terpolymer with a butadiene rubber phase[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/cm³1.04 (Polymaker PolyLite ABS and ABS Pro) to 1.06 (ABS Max), ISO 1183; Bambu Lab 1.05[5][1][6][7]1.41 (extruded POM-C stock)[3]
Typical priceUSD/kg1 kg spools cluster near 20[8][9][10][11][12]Not documented
Price range across brandsUSD/kg12–45 across brands; IEMAI 12, SUNLU 12 at a 3 kg minimum, ELEGOO 15 in a 5 kg pack, Polymaker 19, YXPOLYER 20, Bambu Lab 20, Push Plastic 25, 3DXTech 45[8][9][13][14][10][11][12][15]Not documented
Market availability1–5Ubiquitous, every brand and retailer[8][9][13][14]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][16][17][18]
Spool sizes & diameters1.75 and 2.85 mm; 1, 5 and 10 kg spools[13][14]Not documented
Typical applicationsEnclosures, automotive interior parts and tooling that must hold shape above PLA's 55 °C ceiling[1][19]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]
Printing Parameters
Nozzle temperature°C240–270 (Bambu Lab); 245–265 (Polymaker PolyLite)[5][1]Not documented
Bed temperature°C80–100 (Bambu Lab); 90–100 (Polymaker)[5][1]Not documented
Enclosure / chamber requirement1–5Enclosure recommended — Polymaker calls a chamber needed at ambient temperature, Bambu Lab requires an enclosed printer and rules out its P1P and A-series machines[1][20]Not documented
Recommended chamber temperature°C45–60 (Bambu Lab)[5]Not documented
Part cooling fan0–80 % (Bambu Lab); off (Polymaker PolyLite)[5][1]Not documented
Bed surface & adhesion aidClean the plate and apply glue — Bambu Lab lists glue as the way to improve adhesion and prevent warping[20]Not documented
Maximum volumetric flow (mm³/s; see test conditions)mm³/s10–16 (PrusaSlicer guidance for ABS/ASA)[21]Not documented
Warping tendency1–5High — enclosure needed for reliable large parts; Bambu Lab attributes surface cracking to cooling stress exceeding interlayer adhesion[20]Not documented
Bed-adhesion difficulty1–5Needs a specific surface plus adhesive[20]Not documented
Stringing / oozing tendency1–5Slight[1]Not documented
Overall printing difficulty1–5Intermediate — dry filament and a tuned profile[20][1]Not documented
Extruder requirementNot documentedApium 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 required1–4Brass fine indefinitely[20]Not documented
Abrasiveness1–5Non-abrasive[20]Not documented
Nozzle clog risk1–5Low — no special hot-end required and clogging is not among the listed drawbacks; Prusa lists no drybox and no hardened nozzle[22][23]Not documented
Heat-creep / jam sensitivity1–5Slightly sensitive[22]Not documented
Hotend requirementNo special hot-end required[22]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.65 % saturated at 25 °C / 55 % RH (Bambu Lab); Polymaker measures 0.51 % maximum uptake for ABS Pro[5][6]Low (0.1-0.3 %) — extruded POM-C stock takes up 0.18 % in 24 h and 0.80 % at saturation (ASTM D570)[3]
Equilibrium moisture content at ~50 % RH%0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[5][6]Not documented
Drying temperature & time80 °C for 8 h (Bambu Lab); 70 °C for 6 h (Polymaker)[5][1]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[24]Not documented
Effect of moisture on strengthPolymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; the loss appears as poor layer adhesion and surface defects rather than a stated strength delta[24]Not documented
Storage requirementSealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[24]Not documented

Environment & Chemical
UV resistance1–5Months outdoors before embrittlement[19]Not documented
Chemical resistanceGood against weak acids, weak alkalis, oils and grease; poor against strong acids; dissolved by acetone[1]Good chemical resistance, particularly to bases; Apium lists resistance to bases as a headline property[3][4]

Electrical & ESD propertiesSurface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[25]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 toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[31][20]Not documented
VOC emission rateµg/min12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[31]Not documented
Ultrafine-particle emission rateparticles/min2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[31]Not documented
Hazardous species emittedStyrene 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[31][20]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[31][20]Not documented
Post-Processing
Sanding & machiningSands well and takes filler; the usual preparation before painting[19]Easy to machine — Ensinger lists machinability as a headline property of POM-C stock[3]
Gluing & solvent weldingSolvent-welds with acetone[1]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works — ABS dissolves in acetone[1]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[32][20]Not documented
Dimensional accuracy & detailWarping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[20]Not documented
Solvents & Solubility
Soluble inAcetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[33][1]Hexafluoroisopropanol dissolves it at room temperature; NMP and DMF only when hot. Laboratory reagents.[34]
Softened or crazed byPetrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[33][35]Acids, oxidants, halogens and hot concentrated zinc chloride attack it; alcohols, ketones and esters do not.[34][33]
Solvent welding & smoothing agentAcetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[36]None — no solvent softens POM below its melting point, which is why it is bolted or heat-welded rather than glued.[34]
