| Price range across brandsUSD/kg | 45–120 across brands; SUNLU 45, YXPOLYER 50, Coex 3D 52, 3DXTech 107 at 750 g pricing; the FR PC/ABS grade runs 120[5][6][7][8] | 42–96 across brands; IEMAI 3D E-WATER 42, YXPOLYER 55, Reli3D 66 at 500 g, Polymaker PolyDissolve S1 67 at 750 g, 3DXTech AquaTek 96 at 750 g in 1.75 mm[5][9][10][12][11] |
| Market availability1–5 | Niche, a handful of specialist brands[5] | Stocked by most mainstream brands[5][9][10][12][11] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 750 g spools[5] | 1.75 and 2.85 mm; 0.5 and 0.75 kg spools[5][9] |
| Typical applications | Electrical enclosures and transport interiors that must meet a flammability rating[1] | Dissolvable support for PLA, TPU, PVB and PETG — Polymaker names those four for PolyDissolve S1[3] |
| Printing Parameters | ||
| Nozzle temperature°C | Not documented | 215–225 (Polymaker PolyDissolve S1)[3] |
| Bed temperature°C | Not documented | 25–60 (Polymaker PolyDissolve S1)[3] |
| Enclosure / chamber requirement1–5 | Enclosure recommended[13] | Open frame is fine[3] |
| Part cooling fan | Not documented | Part cooling fan required (Simplify3D)[14] |
| Bed surface & adhesion aid | Clean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[13][15] | PEI sheet or painter's tape[14] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | 4–12 at Polymaker's 50–150 mm/s on a 0.4 mm nozzle at 0.2 mm layer[3] |
| Warping tendency1–5 | High — enclosure needed for reliable large parts[13] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[13] | Sticks to most surfaces[14] |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[16] | Moderate — retraction tuning needed[14] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[13] | Intermediate — dry filament and a tuned profile; PVA is unusable once it has taken up moisture[17][3] |
| Extruder requirement | Not documented | A second extruder or a tool changer; PVA is a support material, not a model material[3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[13] | Brass fine indefinitely[3] |
| Abrasiveness1–5 | Non-abrasive[1] | Non-abrasive[3] |
| Nozzle clog risk1–5 | Low — 3DXTech lists no special nozzle concerns and no minimum layer height for its FR-ABS, only an 80 °C pre-dry[18] | Very high — frequent jams without careful setup; wet PVA foams and carbonises in the nozzle[17] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[15] | High — all-metal hotend and strong cooling needed; Simplify3D warns PVA clogs if the nozzle is left hot while not extruding[14] |
| Hotend requirement | No special hot-end required[15] | No special hot-end required, but the nozzle must not be parked hot[14] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — the ABS matrix takes up 0.51–0.65 % saturated at 25 °C / 55 % RH and 3DXTech specifies a 80 °C, 4 h pre-dry[4][19][18] | Very high (>2 %) — Polymaker measures 10.21 % equilibrium water absorption, by far the highest in the dataset[3] |
| Equilibrium moisture content at ~50 % RH% | Not documented | 10.21 equilibrium water absorption (Polymaker PolyDissolve S1)[3] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[17] | Bubbling and popping at the nozzle, stringing and a rough surface; with PVA this progresses to clogging[17] |
| Effect of moisture on strength | Polymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; absorbed water flashes to steam in the hotend and shows as bubbling and poor layer adhesion[17] | Polymaker groups PVA with nylon as the most moisture-prone class and says it often has to stay in a dryer while printing; there is no published dry-versus-conditioned strength comparison because PVA is not a structural material[17] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity[17] | Sealed with desiccant at all times; PVA takes up water faster than any other filament here[17][3] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 45 at break (printed XY, ISO 527)[1] | Not documented |
| Young's modulusMPa | 1990 (printed XY, ISO 527)[1] | Not documented |
| Elongation at break% | 4 at break (printed XY, ISO 527) — well below the 10 % of unfilled 3DXTech ABS[1][20] | Not documented |
| Flexural strengthMPa | 80 (printed XY, ISO 178)[1] | Not documented |
| Flexural modulusMPa | 2250 (printed XY, ISO 178)[1] | Not documented |
| Brittleness1–5 | Moderate — elongation at break falls to 4 % from 10 % for the unfilled grade[1][20] | Not documented |
| Creep resistance / sustained load1–5 | Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1][20] | Poor — deforms under load at room temperature; PVA is not used structurally[2] |
| Fatigue / repeated-flex resistance1–5 | Below average — no S-N curve found; elongation at break falls to 4 % against 10 % for unfilled 3DXTech ABS[1][20] | Poor — fails after a few cycles[2] |
| Elasticity / flexibility1–5 | Rigid[1] | Not documented |
| Wear resistance & friction | Not documented | 3DXTech marks tensile strength, modulus and elongation as not applicable for its PVA support grade — it is not characterised as a structural material[2] |
| Thermal Properties | ||
| Glass transition (Tg)°C | 105 (DSC)[1] | 60 (3DXTech AquaTek, DSC)[2] |
| Continuous service temperature°C | Not documented | Bounded by a glass transition of 60 °C[2] |
| Flammability / UL 94 | UL 94 V-0 at 1.5 mm, rated on the base resin rather than the printed part[1] | Flammable; no UL 94 rating published[2] |
| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Degrades within weeks outdoors, and dissolves in rain long before UV matters[3] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[21] | Dissolves in water; unusable in any wet or humid service environment[3][14] |
| Water / humidity resistance in service1–5 | Not documented | Dissolves or disintegrates — by design[3][2] |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[16] | Not offered as a food-contact material[2] |
| Biodegradability / compostability | Not biodegradable[16] | PVA is water-soluble and biodegrades in wastewater treatment, but Simplify3D notes disposal should follow local guidance[14] |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[16] | Dissolved PVA goes to drain rather than to recycling[14] |
| Electrical & ESD properties | Not documented | Surface resistance above 10^13 ohm/sq (ASTM D257, 3DXTech AquaTek PVA)[2] |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[22][13] | Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[22] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[22] | Not documented |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[22] | Not documented |
| Hazardous species emitted | Styrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[22][13] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[22][13] | Open a window / occasional ventilation[22] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[16] | Not sanded — it is dissolved away rather than finished[14] |
| Painting & finishing | Paints readily after light abrasion[16] | Not documented |
| Gluing & solvent welding | Not documented | Not applicable — PVA is a sacrificial support[14] |
| Vapour / chemical smoothing | Not documented | Water is the solvent; no vapour smoothing is used[3] |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[23][13] | This is the support material; Polymaker pairs PolyDissolve S1 with PLA, TPU, PVB and PETG[3] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[24][21] | Water — tap water works cold, warm moving water is faster; 6–12 h typical, changing the water every few hours.[25][26] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[24][27] | Nothing else: polyvinyl alcohol resists organic solvents, so an IPA or acetone rinse leaves the support intact.[28] |
| Solvent welding & smoothing agent | Acetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[29] | None — water dissolves PVA rather than welding it, and no solvent gives it a smoothed surface.[25] |
