AB The application of techniques to improve the surface finish of pieces obtained by fuseddeposition modelling, as well as other functional aspects, is of great interest nowadays. Polylacticacid, a biodegradable material, has been considered a possible substitute for petroleum-basedpolymers. In this work, different chemical post-processing methods are applied to polylactic acidpieces obtained by fused deposition modelling and some characteristics are studied. Structural,thermal, and crystallinity property changes are analyzed according to the treatments applied. Thiscan prevent degradation, eliminate the glass transition phase of the material, and thereby increasethe thermal resistance by about 50  C. An improvement in the roughness of the pieces of up to 97%was also found.
