Market snapshot
Listing priceUSD/kg; dated snapshots$19.09/kg median; $10.99–$32.16/kg across 10 dated product listingsNot documented
Identity & Market
Base polymer / chemistryPLA compounded with a mineral filler — Fiberlogy names chalk — that scatters light into a diffuse finish[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/cm³1.31 (Bambu Lab, ISO 1183) to 1.38 (Fiberlogy PLA Mineral, method not stated) — above plain PLA from the filler[2][1]1.41 (extruded POM-C stock)[3]
Typical priceUSD/kgMainstream 1 kg spools cluster near 21[5][6][7]Not documented
Price range across brandsUSD/kg11–32 across brands; budget house brands 11–19, Fiberlogy PLA Mineral 32[8][6][9]Not documented
Market availability1–5Stocked by most mainstream brands[8][7][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[4][10][11][12]
Spool sizes & diameters1.75 mm; 1 kg spools plus spool-less refills[5][13]Not documented
Typical applicationsDisplay models and visible parts where a matte, non-reflective finish matters[2]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]
Diameter tolerance± mm±0.03 (Bambu Lab)[14]Not documented

Bed-adhesion difficulty1–5Sticks to anything[15]Not documented
Overall printing difficulty1–5Beginner — prints on any machine out of the box[2][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[16][2][1]Not documented
Abrasiveness1–5Slightly abrasive — mineral filler pushes density from 1.24 to 1.31–1.38[1][2][17]Not documented
Nozzle clog risk1–5Very low[16]Not documented
Heat-creep / jam sensitivity1–5Moderate — good heatbreak cooling needed; PLA softens below 60 °C[18]Not documented
Hotend requirementNo special hot-end required[15]Not documented
Moisture Behaviour
Moisture absorption (hygroscopicity)1–5Moderate — 0.40 % saturated at 25 °C / 55 % RH[2]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%0.40 saturated at 25 °C / 55 % RH (Bambu Lab)[2]Not documented
Drying temperature & time50 °C for 8 h in a forced-air dryer, or 60–70 °C for 12 h on an X1 heatbed; Fiberlogy specifies 50 °C for 6 h[2][1][19]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing, rough surface and weak layers[20]Not documented
Effect of moisture on strengthPolymaker rates PLA low-sensitivity — the loss shows as poor layer adhesion and brittle layers rather than a published strength figure[20]Not documented
Storage requirementSealed with desiccant below 20 % RH; shelf life at ambient is long[17][15]Not documented
Mechanical Properties
Tensile strength (XY)MPa30 (printed XY, ISO 527, Bambu Lab); 35.1 on My Tech Fun bars for PolyTerra PLA[2][21]66.9 at break and 64.1 at yield (extruded POM-C stock, ASTM D638; converted from 9700 and 9300 psi)[3]

Environment & Chemical
UV resistance1–5Degrades within weeks outdoors[18][24]Not documented
Chemical resistanceGood against weak acids, oils and grease; poor against strong acids and alkalis; dissolved by chloroform, THF and hot benzene[23][18]Good chemical resistance, particularly to bases; Apium lists resistance to bases as a headline property[3][4]
Water / humidity resistance in service1–5Good — insoluble in water[17]Good — minor absorption; 0.80 % water at saturation (ASTM D570, extruded stock)[3]
Food contactBase resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[18]Not documented
Biodegradability / compostabilityIndustrially compostable only — needs sustained 55 °C; not home compostable[25][18]Not documented
RecyclabilityMechanically recyclable; not accepted in household plastic collection[25]Not documented
Electrical & ESD propertiesNot documentedVolume 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 toxicity1–5Low hazard — minimal VOC and particle emission[26]Not documented
Ventilation / filtration requirement1–5None needed in a normal room[26]Not documented
Post-Processing
Sanding & machiningWet sanding — dry sanding heats the surface by friction and smears it[24][18]Easy to machine — Ensinger lists machinability as a headline property of POM-C stock[3]
Gluing & solvent weldingCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[18][27]Not documented
Vapour / chemical smoothingNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[18]Not documented
Support material pairingSupport for PLA (Bambu Lab)[2]Not documented
Dimensional accuracy & detailMatte surface hides layer lines; 55° overhangs and 30 mm bridges as for plain PLA[2]Not documented
Solvents & Solubility
Soluble inChloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[28]Hexafluoroisopropanol dissolves it at room temperature; NMP and DMF only when hot. Laboratory reagents.[29]
Softened or crazed byAcetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[28][30]Acids, oxidants, halogens and hot concentrated zinc chloride attack it; alcohols, ketones and esters do not.[29][31]
Solvent welding & smoothing agentChloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[32][30]None — no solvent softens POM below its melting point, which is why it is bolted or heat-welded rather than glued.[29]
