MÉTODOS: 140 espécimes foram impressos em impressoras 3D do tipo SLA (estereolitografia a laser) e DLP (estereolitografia por processamento digital de luz) para cada teste mecânico realizado e foram divididos em 28 grupos, de acordo com a resina (4 tipos: Blue, Gray, Surgical Guide, Standard) e o tempo de pós cura com luz ultravioleta (7 tempos: 0, 5, 10, 15, 30, 60 e 120 minutos). Foram realizados os testes de microdureza Vickers, tração diametral e flexão três pontos. Os dados obtidos foram submetidos a uma ANOVA de dois níveis e ao pós teste de Tukey. Para a avaliação das alterações dimensionais de modelos odontológicos foram realizados dois experimentos distintos. No primeiro, 56 modelos odontológicos do arco maxilar em formato de ferradura foram impressos na impressora MoonRay S100 (SprintRay) com a resina Gray (SprintRay), variando a orientação de impressão, a presença de barra e o processo de pós cura. Depois de impressos foram escaneados em escâner de mesa R700 (3Shape) e então foram realizadas as medições transversais entre caninos, primeiros e segundos pré-molares e molares e de comprimento de arco no software VistaDent OC (Dentsply Sirona). No segundo, 56 modelos foram impressos com a mesma resina e impressora, variando o tipo de modelo, presença de barra e polimerização. Foram então escaneados com o escâner R700 e utilizado o software VistaDent para a realização das mesmas medidas da metodologia anterior. RESULTADOS: O tempo e a resina influenciaram os valores de microdureza, resistência à tração e à flexão (p
