Abstract: A three-dimensional printing apparatus including a body, a rotation module, a tank, an elevating module, a forming platform, a curing module, and a control module is provided. The rotation module and the elevating module are disposed on the body. The tank is disposed on the rotation module. The forming platform is disposed on the elevating module. The curing module disposed in the body and under the tank. The control module is electrically connected to the rotation module, the elevating module, and the curing module. The forming platform dips into the forming material in liquid in the tank and the curing module cures the forming material between the forming platform and an inner bottom of the tank to form a solidification layer. Then the elevating module and the rotation module respectively drive the forming platform to rise and rotate relatively to the tank simultaneously.

Abstract: A laser module with removable structures of three-dimensional printer includes a platform, a carrying seat and a laser module. The platform has a working side and a movement mechanism; the movement mechanism at least has a displacement rod. The carrying seat is disposed on the displacement rod, and the movement mechanism drives the carrying seat to move on the working side along the displacement rod. The carrying seat has an assembly portion, and the laser module is disposed on the assembly portion of the carrying seat and detachably integrated with the assembly portion as a whole. Thereby the purposes of fast and convenient disassembly can be achieved through assembling the laser module on the carrying seat.

Abstract: A stereolithography apparatus including a base, an elevator track, a threaded rod, a sliding bracket, a nut, a plurality of friction-reducing components, and a printing platform. The sliding track is disposed on the base. The threaded rod is disposed on the base and an axial direction of the threaded rod is parallel to the elevator track. The sliding bracket is slidably disposed on the elevator track. The nut is set on the threaded rod to be driven by the threaded rod to slide along the threaded rod. The sliding bracket clamps the nut to be driven by the nut to slide along the elevator track. The friction-reducing components are disposed between the nut and the sliding bracket for the nut to move relatively to the sliding bracket. The printing platform is disposed on the sliding bracket to slide with the sliding bracket along the elevator track.

Abstract: A three-dimensional printer includes a platform, a lifting mechanism and a carrying base, wherein the lifting mechanism includes a vertical screw, a linear sliding rail, a movable component, a stand and a pair of limiting members. The linear sliding rail is arranged with the vertical screw in parallel. One end of the movable component is disposed with an inner screw hole while the other end has a guide portion. The guide portion is vertically connected to the linear sliding rail in a slidable manner. The stand is disposed on the horizontal two sides of the movable component. The pair of limiting members is respectively sandwiched between the two sides of the movable component and the stand. One end of each limiting member is fixed to the movable component while the other end has a sliding portion. Each sliding portion abuts on the stand.
