| Price range across brandsUSD/kg | 19–80 across brands; IEMAI 19, LANDU 24, SUNLU 27, Polymaker 30, Bambu Lab 32, 3DXTech 47, Proto-pasta 80[8][7][6][11][9][12][10] | Not documented |
| Market availability1–5 | Stocked by most mainstream brands[7][8][6][11] | 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][13][14][15] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.5, 0.75, 1 and 3 kg spools[11][6][16] | Not documented |
| Typical applications | Stiff jigs, drone and RC frames, tool holders — matte black finish, no gain in tensile strength[5][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)[7] | Not documented |

| Warping tendency1–5 | None[5] | Not documented |
| Stringing / oozing tendency1–5 | Slight[2] | Not documented |
| Overall printing difficulty1–5 | Easy — minor profile tuning; needs a hardened nozzle and 0.4 mm or larger[17][2] | Not documented |
| Extruder requirement | Nozzles below 0.4 mm are not compatible (Bambu Lab)[17] | 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[4] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Hardened steel required[17][2] | Not documented |
| Abrasiveness1–5 | Highly abrasive — standard CF composite[17][19] | Not documented |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle[17] | Not documented |
| Hotend requirement | Hardened steel nozzle; Bambu Lab lists PLA-CF among the filaments its hardened-steel nozzle exists for[19][17] | Not documented |
| Other hardware wear | Bambu Lab reports AMS wear; Polymaker advises against running PLA-CF through an AMS at all[17][2] | Not documented |
| Moisture Behaviour | ||

| Drying temperature & time | 55 °C for 6–8 h[5][2] | Not documented |
| Effect of moisture on strength | Polymaker rates PLA low-sensitivity and publishes no dry-versus-conditioned figures for this grade; absorbed water flashes to steam and shows as bubbling and poor layer adhesion[20] | Not documented |

| Creep resistance / sustained load1–5 | Poor — 12 mm bars sagged to 15.1, 19.8 and 21.3 mm over 5 days at 1.25 kg across three brands, against 16.2–21.8 mm for their unfilled PLA[22][23][21] | Not documented |
| Fatigue / repeated-flex resistance1–5 | Poor — no CF-grade S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and elongation in Z falls to 0.9 %[24][2] | Not documented |
| Elasticity / flexibility1–5 | Rigid[2] | Not documented |
| Z strength as % of XY% | 48 (Polymaker) to 68 (Bambu Lab), printed[5][2] | 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[3][4] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 54 (Polymaker) to 55 (Bambu Lab), ISO 75 at 0.45 MPa[5][2] | 158 (extruded POM-C stock, ASTM D648 at 66 psi; converted from 316 °F)[3] |
| HDT at 1.8 MPa°C | 50 (Polymaker) to 54 (Bambu Lab), ISO 75 at 1.8 MPa[5][2] | 110 (extruded POM-C stock, ASTM D648 at 264 psi; converted from 230 °F)[3] |

| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[25] | Not documented |

| Water / humidity resistance in service1–5 | Not documented | Good — minor absorption; 0.80 % water at saturation (ASTM D570, extruded stock)[3] |
| 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[3][4] |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission[26] | Not documented |
| Ventilation / filtration requirement1–5 | None needed in a normal room[26] | Not documented |
| Dust & fibre handling hazard | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[1] | Not documented |
| Post-Processing | ||
| Sanding & machining | Not documented | Easy to machine — Ensinger lists machinability as a headline property of POM-C stock[3] |
| Support material pairing | Support for PLA (Bambu Lab); PolySupport and PolyDissolve S1 (Polymaker)[5][2] | Not documented |
| Dimensional accuracy & detail | Matte finish hides layer lines; stiffness is the gain — tensile strength stays at or below Bambu Lab PLA Basic's 35 MPa and Polymaker PolyLite PLA's 52.3 MPa[5][2][27][28] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[29] | Hexafluoroisopropanol dissolves it at room temperature; NMP and DMF only when hot. Laboratory reagents.[30] |
| Softened or crazed by | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[29][31] | Acids, oxidants, halogens and hot concentrated zinc chloride attack it; alcohols, ketones and esters do not.[30][32] |
| Solvent welding & smoothing agent | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[33][31] | None — no solvent softens POM below its melting point, which is why it is bolted or heat-welded rather than glued.[30] |
