| Property | Flame-retardant ABS (FR-ABS)ABS | BVOH (soluble support)SUPPORT |
|---|---|---|
| Market snapshot | ||
| Listing priceUSD/kg; dated snapshots | $52.00/kg median; $44.99–$120.00/kg across 5 dated product listings | $165.72/kg median; $165.72–$165.72/kg across 1 dated product listings |
| Identity & Market | ||
| Base polymer / chemistry | ABS with a flame-retardant package; 3DXTech rates the base resin UL 94 V-0[1] | Butenediol vinyl alcohol copolymer — a vinyl alcohol copolymer that dissolves faster and in cooler water than straight PVA[2] |
| Densityg/cm³ | 1.18 (ISO 1183) — above unfilled ABS at 1.05 because of the retardant loading[1][3] | Not documented |
| Typical priceUSD/kg | 1 kg-equivalent spools span 45–120; the middle of the market is about 52[4][5][6][7] | 1 kg-equivalent spools cluster near 166[2] |
| 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[4][5][6][7] | 166 at Fiberlogy's 500 g pricing on 3DJake[2] |
| Market availability1–5 | Niche, a handful of specialist brands[4] | Niche, a handful of specialist brands[2] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 750 g spools[4] | 1.75 and 2.85 mm; 0.5 kg spools[2] |
| Typical applications | Electrical enclosures and transport interiors that must meet a flammability rating[1] | Dissolvable support where PVA dissolves too slowly, and for materials PVA bonds to poorly[2] |
| Printing Parameters | ||
| Enclosure / chamber requirement1–5 | Enclosure recommended[8] | Open frame is fine[9] |
| Bed surface & adhesion aid | Clean the plate and apply glue; Simplify3D also lists Kapton tape and ABS slurry[8][10] | Not documented |
| Warping tendency1–5 | High — enclosure needed for reliable large parts[8] | Not documented |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[8] | Not documented |
| Stringing / oozing tendency1–5 | Slight — Polymaker advises 1–2 mm retraction at 20–30 mm/s[11] | Not documented |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[8] | Intermediate — dry filament and a tuned profile[12] |
| Extruder requirement | Not documented | A second extruder or a tool changer[9] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[8] | Brass fine indefinitely[9] |
| Abrasiveness1–5 | Non-abrasive[1] | Non-abrasive[9] |
| 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[13] | Very high — frequent jams without careful setup[12] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[10] | Not documented |
| Hotend requirement | No special hot-end required[10] | Not documented |
| 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[3][14][13] | Very high (>2 %) — the vinyl alcohol backbone is what makes it soluble[12][9] |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing and a rough surface[12] | Not documented |
| 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[12] | Not a structural material; no dry-versus-conditioned data is published[12] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity[12] | Sealed with desiccant at all times[12] |
| 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][15] | 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][15] | Not documented |
| Creep resistance / sustained load1–5 | Moderate — no creep test found; Tg of 105 °C keeps room-temperature service far below softening[1][15] | Not documented |
| 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][15] | Not documented |
| Elasticity / flexibility1–5 | Rigid[1] | Not documented |
| Thermal Properties | ||
| Glass transition (Tg)°C | 105 (DSC)[1] | Not documented |
| Flammability / UL 94 | UL 94 V-0 at 1.5 mm, rated on the base resin rather than the printed part[1] | Not documented |
| Environment & Chemical | ||
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; dissolved by acetone[16] | Not documented |
| Water / humidity resistance in service1–5 | Not documented | Dissolves or disintegrates — by design[2] |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[11] | Not documented |
| Biodegradability / compostability | Not biodegradable[11] | Not documented |
| Recyclability | Mechanically recyclable but not accepted in household plastic collection[11] | Not documented |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[17][8] | Low hazard — minimal VOC and particle emission; none of these materials was in the chamber study[17] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[17] | 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[17] | 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[17][8] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[17][8] | Open a window / occasional ventilation[17] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler before painting[11] | Not documented |
| Painting & finishing | Paints readily after light abrasion[11] | Not documented |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[18][8] | This is the support material[2] |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[19][16] | Water: about 1 g of BVOH per 20 g of water, several hours; warmer water is faster but must not be too hot.[20][2] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[19][21] | Nothing else — a vinyl alcohol copolymer resists organic solvents, so IPA or acetone will not touch it.[22] |
| 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.[23] | None — water is a removal solvent, not a welding one.[20] |
