RecyclabilityNot documentedMechanically recyclable; not accepted in household plastic collection[27]
Health & Safety
Fume toxicity1–5Not documentedLow hazard — minimal VOC and particle emission[28]
Ventilation / filtration requirement1–5Not documentedNone needed in a normal room[28]
Post-Processing
Sanding & machiningNot documentedWet sanding — dry sanding heats the surface by friction and smears it[26][20]
Gluing & solvent weldingNot documentedCyanoacrylate for most joints; some grades partially dissolve and bond with acetone[20][29]
Vapour / chemical smoothingNot documentedNo practical vapour smoothing — only chloroform, hot benzene or THF, which are laboratory-only[20]
Support material pairingNot documentedPolySupport and PolyDissolve S1 (Polymaker)[2]
Solvents & Solubility
Soluble inNot documentedChloroform: 10 % w/v in 2–4 h at 23 °C, every grade and morphology; THF and DMF only at 65 °C. Laboratory reagents.[30]
Softened or crazed byNot documentedAcetone, ethyl acetate and toluene plasticise it but dissolve <1 % even at 65 °C; submersion in acetone crazes and destroys parts.[30][31]
Solvent welding & smoothing agentNot documentedChloroform vapour smooths and welds PLA at the cost of tensile strength; acetone does not smooth it at all.[32][31]

Material entries describe families or representative grades, not an interchangeable specification for every spool. Test methods, orientations and conditions may differ. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
