The The layer thickness was set at one hundred , and also a and P have been printed inprinted in and Leptomycin B Formula 60-degree directions. The SLA-type 3D printer utilised Groups A and P had been 0-degree- 0-degree- and 60-degree directions. The SLA-type 3D for model printing includes a point has a of nmsize , and , laserthe laser is 50 mW, employing printer utilised for model printing size point 85 of nm 85 the and output output is 50 mW, Low Force Stereolithography printing tactic. For the handle group,group, the full-arch working with Low Force Stereolithography printing approach. For the control the full-arch group was printed at 0 degrees, and totally filled groupgrouponly 1 direction has printed. The group was printed at 0 degrees, and completely filled was was only a single direction has printed. model help structure of eacheach group was attached under model. The model help structure of group was attached below the the model. Table 1 lists the resin consumption as outlined by the kind of printed tooth model.
