Abstract: A stereolithographic apparatus has a machine body disposed with a swept platform, which has a recess formed by recessing into a circumference of the swept platform. A build platform driven by the linear actuator to move is aligned with and abuts against a recess. A motor and a light-emitting device are disposed in the machine body. The motor drives a recoating blade to sweep on the swept platform and the build platform. By rotating the recoating blade, the slurry material could circularly spread the slurry material onto the build platform to form multiple build layers. After each build layer is spread, the light-emitting device irradiates the build layer to partially cure the build layer to form a build layer. By repeating the aforementioned process, the build layers are formed to pile as a printed product (e.g. green body), thereby rapidly producing a delicate product without supporting structure.
