| Environment & Chemical | ||
| UV resistance1–5 | Not documented | Degrades within weeks outdoors[21][26] |

| Water / humidity resistance in service1–5 | Dissolves or disintegrates — by design[1] | Good — insoluble in water[14] |
| Food contact | Not documented | Base resin is food-contact grade, but printed layer grooves harbour bacteria; Prusa advises against food use[21] |
| Biodegradability / compostability | Not documented | Industrially compostable only — needs sustained 55 °C; not home compostable[27][21] |
| Recyclability | Not documented | Mechanically recyclable; not accepted in household plastic collection[27] |
| Health & Safety | ||

| Ventilation / filtration requirement1–5 | Open a window / occasional ventilation[28] | None needed in a normal room[28] |
| Post-Processing | ||
| Sanding & machining | Not documented | Wet sanding — dry sanding heats the surface by friction and smears it[26][21] |
| Gluing & solvent welding | Not documented | Cyanoacrylate for most joints; some grades partially dissolve and bond with acetone[21][29] |
| Vapour / chemical smoothing | Not documented | No practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[21] |
| Support material pairing | This is the support material[1] | PolySupport and PolyDissolve S1 (Polymaker)[2] |
| 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.[30][1] | Chloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[31] |
| Softened or crazed by | Nothing else — a vinyl alcohol copolymer resists organic solvents, so IPA or acetone will not touch it.[32] | Acetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[31][33] |
| Solvent welding & smoothing agent | None — water is a removal solvent, not a welding one.[30] | Chloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[34][33] |
