Overall printing difficulty1–5Intermediate — dry filament and a tuned profile; hardened nozzle mandatory[14]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[5]
Hardware Wear & Reliability
Nozzle hardness required1–4Hardened steel required[14]Not documented
Abrasiveness1–5Highly abrasive — standard CF composite[14]Not documented

Drying temperature & time80 °C for 8 h (Bambu Lab)[1]Not documented
Symptoms when wetBubbling and popping at the nozzle, stringing and a rough surface[20]Not documented
Effect of moisture on strengthNo dry-versus-conditioned figures are published; Polymaker groups the styrenics as moderate-sensitivity and absorbed water shows as bubbling and poor layer adhesion[20]Not documented
Storage requirementSealed with desiccant; Polymaker rates the styrenics moderate-sensitivity[20]Not documented

Wear resistance & frictionNot documentedWear 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[4][5]
Thermal Properties
HDT at 0.45 MPa°C110 (ISO 75, 0.45 MPa, Bambu Lab) against 100 for unfilled Bambu Lab ASA[1][21]158 (extruded POM-C stock, ASTM D648 at 66 psi; converted from 316 °F)[4]

Food contactNot food safe[15]Not documented
Biodegradability / compostabilityNot biodegradable[15]Not documented
RecyclabilityNot accepted in household plastic collection[15]Not documented
Electrical & ESD propertiesSurface resistance above 10⁹ ohm/sq — not static-dissipative (3DXTech, ASTM D257)[2]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[4][5]
Health & Safety
Fume toxicity1–5High — hazardous VOC such as styrene; enclosure and filtration needed[25][14]Not documented
Hazardous species emittedStyrene. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea. Azimi et al. measured styrene from every styrenic filament tested but did not test ASA itself[14][25]Not documented
Ventilation / filtration requirement1–5Enclosure with carbon and HEPA filtration[25][14]Not documented
Dust & fibre handling hazardCarbon fibre is bound in the matrix; sanding dust should not be inhaled[2]Not documented
Post-Processing
Sanding & machiningSands well and takes filler before painting[15]Easy to machine — Ensinger lists machinability as a headline property of POM-C stock[4]
Painting & finishingPaints readily; ASA holds colour outdoors so many parts are left unpainted[15]Not documented
Gluing & solvent weldingSolvent-welds with acetone[22]Not documented
Vapour / chemical smoothingAcetone vapour smoothing works[22]Not documented
Support material pairingHIPS breaks away or dissolves in d-limonene; Bambu Lab sells a Support for ABS that also serves ASA[14]Not documented
Dimensional accuracy & detailMatte fibre-filled finish hides layer lines[1]Not documented
Solvents & Solubility
Soluble inAcetone dissolves the resin and leaves the fibre; MEK, THF, ethyl acetate and chlorinated solvents attack the styrenic backbone.[26][22]Hexafluoroisopropanol dissolves it at room temperature; NMP and DMF only when hot. Laboratory reagents.[27]
Softened or crazed byLimonene attacks some grades — Prusa reports Prusament ASA Orange flaking apart as layer adhesion fails.[28]Acids, oxidants, halogens and hot concentrated zinc chloride attack it; alcohols, ketones and esters do not.[27][26]
Solvent welding & smoothing agentAcetone vapour reaches only the resin fraction, so the fibre is left standing proud of the smoothed surface.[29][22]None — no solvent softens POM below its melting point, which is why it is bolted or heat-welded rather than glued.[27]
