| Identity & Market | ||
| Base polymer / chemistry | Polyoxymethylene, normally the copolymer POM-C. Apium's filament grade is POM-C with antistatic additives; no unfilled POM filament was found on sale[1][2] | Carbon-fibre reinforced PPS — Polymaker's Fiberon grade is nominally 10 wt%[3] |
| Densityg/cm³ | 1.41 (extruded POM-C stock)[1] | 1.29 (Fiberon PPS-CF10) and 1.36 (Fiberon PPS-GF20), ISO 1183[3][4] |
| Typical priceUSD/kg | Not documented | 1 kg-equivalent spools span 93–174; the middle of the market is about 140[5][6][7][8] |
| Price range across brandsUSD/kg | Not documented | 93-174 across brands and formats; Polymaker Fiberon PPS-GF20 93 at 3 kg, IEMAI 3D CF-PPS 131 at 750 g, LEHVOSS Luvocom 3F PPS CF 9938 164 at 2.3 kg, Bambu Lab PPS-CF 174 at 750 g[5][6][7][8] |
| Market availability1–5 | 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[2][9][10][11] | Available from several mainstream brands[5][6][7] |
| Spool sizes & diameters | Not documented | 1.75 mm; 0.5 kg spools[5] |
| Typical applications | Gears, bushings, bearings, conveyor and food-machinery parts; Apium markets its POM-C ESD grade for semiconductor insulators, aerospace fasteners and sliding parts[1][2] | Chemical and automotive parts needing PPS chemistry with structural stiffness[3] |
| Printing Parameters | ||
| Enclosure / chamber requirement1–5 | Not documented | Enclosure required (passive) — Polymaker states its Fiberon PPS-CF10 needs no heated chamber, unlike the unfilled sulfones and PAEKs[3] |
| Overall printing difficulty1–5 | Not documented | Expert / industrial hardware only[3] |
| Extruder requirement | 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[2] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Not documented | Hardened steel required[3] |
| Abrasiveness1–5 | Not documented | Highly abrasive — standard CF composite[3] |
| Nozzle clog risk1–5 | Not documented | High — jams from moisture, heat creep or particles; Polymaker specifies hardened steel or ruby nozzles for carbon-filled PPS and Prusa lists composites as a higher clogging risk[12][13] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Low (0.1-0.3 %) — extruded POM-C stock takes up 0.18 % in 24 h and 0.80 % at saturation (ASTM D570)[1] | Low (0.1–0.3 %) — 0.225 % equilibrium for Fiberon PPS-CF10 and 0.11 % for PPS-GF20[3][4] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 0.225 equilibrium (Fiberon PPS-CF10); 0.11 (PPS-GF20)[3][4] |
| Effect of moisture on strength | Not documented | No dry-versus-conditioned figures are published; equilibrium uptake is 0.225 % and Polymaker specifies a 100 °C, 10 h dry[3] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 66.9 at break and 64.1 at yield (extruded POM-C stock, ASTM D638; converted from 9700 and 9300 psi)[1] | 59.4 ± 1.3 (PPS-CF10) and 64.1 ± 2.1 (PPS-GF20) printed XY, ISO 527[3][4] |
| Young's modulusMPa | 2275 (extruded POM-C stock, ASTM D638; converted from 330,000 psi)[1] | 5446.7 ± 149.0 (PPS-CF10) and 4552.0 ± 54.6 (PPS-GF20) printed XY, ISO 527[3][4] |

| Creep resistance / sustained load1–5 | Not documented | Excellent — holds load for years. Ensinger lists high creep resistance for unfilled PPS stock and Spectrum states creep resistance is unchanged under continuous load at high temperature; the fibre raises heat deflection to 252 °C at 0.45 MPa[14][15][3] |
| Elasticity / flexibility1–5 | Not documented | Rigid[3] |
| Z strength as % of XY% | Not documented | 54 (PPS-CF10) and 36 (PPS-GF20), printed[3][4] |

| Flammability / UL 94 | UL 94 HB on extruded POM-C stock[1] | Not documented |
| Environment & Chemical | ||
| Chemical resistance | Good chemical resistance, particularly to bases; Apium lists resistance to bases as a headline property[1][2] | Outstanding — PPS resists essentially all solvents below 200 °C[12] |
| Water / humidity resistance in service1–5 | Good — minor absorption; 0.80 % water at saturation (ASTM D570, extruded stock)[1] | Not documented |
| Electrical & ESD properties | 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[1][2] | Surface resistivity above 10¹² ohm — insulating (ANSI/ESD S11.11)[3][4] |
| Health & Safety | ||
| Fume toxicity1–5 | Not documented | Moderate — measurable VOCs and UFPs, ventilation advised. None of these polymers was in the chamber study, and all are processed far above the temperatures it covered[16] |
| Ventilation / filtration requirement1–5 | Not documented | Ventilated room or enclosure recommended[16] |
| Dust & fibre handling hazard | Not documented | Fibre is bound in the matrix; sanding dust should not be inhaled[3] |
| Post-Processing | ||
| Sanding & machining | Easy to machine — Ensinger lists machinability as a headline property of POM-C stock[1] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Hexafluoroisopropanol dissolves it at room temperature; NMP and DMF only when hot. Laboratory reagents.[17] | None — PPS does not dissolve in any known solvent below 200 °C.[18][19] |
| Softened or crazed by | Acids, oxidants, halogens and hot concentrated zinc chloride attack it; alcohols, ketones and esters do not.[17][19] | Nothing at 23 °C; Ensinger rates it only conditionally resistant to benzene, dichloromethane, toluene and pyridine.[19] |
| Solvent welding & smoothing agent | None — no solvent softens POM below its melting point, which is why it is bolted or heat-welded rather than glued.[17] | None — no solvent welds or smooths PPS.[18] |
