| Identity & Market | ||
| Base polymer / chemistry | Butenediol vinyl alcohol copolymer — a vinyl alcohol copolymer that dissolves faster and in cooler water than straight PVA[1] | Carbon-filled polyamide compounded to a static-dissipative resistivity — Polymaker's grade uses a PA612 matrix[2] |
| Densityg/cm³ | Not documented | 1.10 (ISO 1183)[2] |
| Typical priceUSD/kg | 1 kg-equivalent spools cluster near 166[1] | 1 kg-equivalent spools cluster near 130[3] |
| Price range across brandsUSD/kg | 166 at Fiberlogy's 500 g pricing on 3DJake[1] | 130 at Polymaker's 0.5 kg pricing[3] |
| Market availability1–5 | Niche, a handful of specialist brands[1] | Special order, 1–2 makers worldwide[3] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.5 kg spools[1] | 1.75 mm; 0.5 kg spools[3] |
| Typical applications | Dissolvable support where PVA dissolves too slowly, and for materials PVA bonds to poorly[1] | Electronics jigs and trays that also need nylon toughness and heat resistance[2] |
| Printing Parameters | ||
| Enclosure / chamber requirement1–5 | Open frame is fine[4] | Enclosure required (passive)[5] |
| Bed surface & adhesion aid | Not documented | PEI sheet with a glue stick, or a dedicated adhesive such as Magigoo[6][5] |
| Bed-adhesion difficulty1–5 | Not documented | Needs a specific surface plus adhesive[6] |
| Stringing / oozing tendency1–5 | Not documented | Moderate — retraction tuning needed[5] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[7] | Expert / industrial hardware only[5][7] |
| Extruder requirement | A second extruder or a tool changer[4] | Not documented |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[4] | Hardened steel required — Polymaker measures brass nozzle life at about 9 h on PA612-ESD and recommends hardened steel or ruby[2] |
| Abrasiveness1–5 | Non-abrasive[4] | Highly abrasive — carbon-filled nylon composite; Polymaker puts brass nozzle life at roughly 9 h on PA612-ESD[2] |
| Nozzle clog risk1–5 | Very high — frequent jams without careful setup[7] | High — jams from moisture, heat creep or particles[7] |
| Heat-creep / jam sensitivity1–5 | Not documented | Moderate — good heatbreak cooling needed[6] |
| Hotend requirement | Not documented | May require an all-metal hot end (Simplify3D)[6] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Very high (>2 %) — the vinyl alcohol backbone is what makes it soluble[7][4] | High (0.8–2 %) — the PA612 matrix sits between PA6 and PA12[8][9] |
| Effect of moisture on strength | Not a structural material; no dry-versus-conditioned data is published[7] | Polymaker publishes dry and wet printed blocks for PA612-ESD itself: at 4.64 % moisture tensile falls 84.3 → 73.6 MPa and modulus 4294 → 3731 MPa[2][9] |
| Storage requirement | Sealed with desiccant at all times[7] | Sealed below 20 % RH with desiccant[7] |
| Hydrolysis at melt temperature | Not documented | Polymaker specifies an 80–100 °C dry and storage below 20 % RH; no molecular-weight loss figure is published, and the wet data it does publish is conditioning rather than melt hydrolysis[10][11] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | Not documented | 84.3 ± 2.3 printed XY dry (annealed 100 °C/16 h), 73.6 ± 2.3 conditioned to 4.64 % moisture, ISO 527[2] |
| Young's modulusMPa | Not documented | 4293.7 ± 116.4 printed XY dry and 3730.8 ± 156.2 conditioned, ISO 527[2] |
| Elongation at break% | Not documented | 3.0 ± 0.1 printed XY dry and 4.2 ± 0.4 conditioned, ISO 527[2] |
| Charpy impact, notchedkJ/m² | Not documented | 5.9 ± 0.4 printed XY dry and 4.9 ± 0.3 conditioned, ISO 179 notched[2] |
| Other impact data | Not documented | Charpy unnotched 24.1 ± 2.4 printed XY and 4.5 ± 0.2 printed Z (ISO 179)[2] |
| Layer adhesion / Z tensileMPa | Not documented | 21.5 ± 2.7 printed Z dry — only a quarter of XY, the most anisotropic nylon composite here; 19.2 ± 1.6 conditioned[2] |
| Brittleness1–5 | Not documented | Brittle — snaps with little warning; elongation 3.0 % in XY and 1.4 % in Z[2] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | Rockwell M88 / R117 on extruded PA66-GF30 stock (ASTM D785); no figure is published for a conductive carbon-filled nylon filament[12] |
| Creep resistance / sustained load1–5 | Not documented | Good. Ensinger rates its PA66-CF30 compound for sustained static and dynamic load at 110 °C continuous service; the PA612 matrix here still takes up 4.64 % moisture at conditioning, which softens it[13][2] |
| Fatigue / repeated-flex resistance1–5 | Not documented | Good. Ensinger states carbon-filled PA66 compounds have improved fatigue strength in tension, flexure and compression[13] |
| Elasticity / flexibility1–5 | Not documented | Rigid[2] |
| Z strength as % of XY% | Not documented | 26 (printed Z against XY tensile)[2] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | Not documented | 157.0 (ISO 75, 0.45 MPa)[2] |
| HDT at 1.8 MPa°C | Not documented | 125.4 (ISO 75, 1.8 MPa)[2] |
| Glass transition (Tg)°C | Not documented | 41.8 (DSC)[2] |
| Melting point / Vicat°C | Not documented | 187.3 melting (DSC); Vicat 190.0 (ISO 306)[2] |
| Flammability / UL 94 | Not documented | Flammable; no UL 94 rating published for the grades surveyed[10] |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Months outdoors before embrittlement — unstabilised polyamide yellows under UV[5] |
| Chemical resistance | Not documented | Withstands oils, fuels and alkalis[5] |
| Water / humidity resistance in service1–5 | Dissolves or disintegrates — by design[1] | Not documented |
| Food contact | Not documented | Not food-contact certified as filament[5] |
| Biodegradability / compostability | Not documented | Not biodegradable[5] |
| Recyclability | Not documented | Not accepted in household plastic collection[5] |
| Electrical & ESD properties | Not documented | Static-dissipative — the reason the grade exists; Polymaker's insulating nylon composites sit above 10¹² ohm by contrast[2][8] |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[14] | Moderate — measurable VOCs and UFPs, ventilation advised[14] |
| VOC emission rateµg/min | Not documented | Up to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study[14] |
| Ultrafine-particle emission rateparticles/min | Not documented | ≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured[14] |
| Hazardous species emitted | Not documented | Caprolactam, at up to 180 µg/min from nylon filament[14] |
| Ventilation / filtration requirement1–5 | Open a window / occasional ventilation[14] | Ventilated room or enclosure recommended[14] |
| Dust & fibre handling hazard | Not documented | Fibre is bound in the matrix; sanding dust should not be inhaled[10] |
| Post-Processing | ||
| Sanding & machining | Not documented | Sands poorly — gums rather than powders[6] |
| Gluing & solvent welding | Not documented | Cyanoacrylate; no common solvent welds polyamide[6] |
| Vapour / chemical smoothing | Not documented | No practical vapour smoothing[6] |
| Support material pairing | This is the support material[1] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Water: about 1 g of BVOH per 20 g of water, several hours; warmer water is faster but must not be too hot.[15][1] | Formic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents.[16] |
| Softened or crazed by | Nothing else — a vinyl alcohol copolymer resists organic solvents, so IPA or acetone will not touch it.[17] | Zinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it.[16] |
| Solvent welding & smoothing agent | None — water is a removal solvent, not a welding one.[15] | None — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway.[16] |
