An in vitro comparison of the dimensional stability of four 3D-printed models under various storage conditions
CONCLUSIONS: Shrinkage of 3D-printed models is pervasive, arising regardless of the material used (PLA or resin) and being independent of the brand or storage conditions. Consequently, immediate utilization of 3D printing for orthodontic appliance purposes may be preferable, with prolonged storage risking the manufacture of inaccurate orthodontic retainers and appliances.PMID:38639456 | DOI:10.2319/081223-557.1
