The utility model discloses a three-dimensional printer convenient to carry, which relates to the technical field of three-dimensional printers and comprises a base, a printing platform is slidably arranged on the top surface of the base, a door-shaped frame is arranged in the middle of the base, threaded holes are formed in the bottom ends of the two sides of the door-shaped frame, and two insertion holes are formed in the two sides of the outer wall of the door-shaped frame. The printing platform is located between the inner walls of the door-shaped frame, a moving rod is slidably arranged on the side wall of the door-shaped frame, and an extruder is slidably arranged on the top face of the moving rod. Fixing blocks are fixedly connected to the two sides of the base. According to the door-shaped frame, when the door-shaped frame is dismantled, only the threaded rod needs to be rotationally dismantled, the inserting rod needs to be pulled out, then the door-shaped frame can be dismantled from the base, when the door-shaped frame is installed, reverse operation is carried out, the door-shaped frame is convenient and rapid to dismantle and install and convenient to carry, and when the door-shaped frame is in a storage state, the transverse door-shaped frame can be fixed through the inserting hole by the inserting rod. Parts are prevented from being damaged due to shaking of the door-shaped frame and the parts on the door-shaped frame when the device is carried, and the safety of the device is protected.

This utility model relates to a 3D printing device suitable for large-size printed parts, belonging to the technical field of 3D printing equipment. It includes a support frame, a printing assembly, a track, and a forming platform. The printing assembly includes a bracket and a sand-laying device and an inkjet printing device mounted on the bracket. The support frame has a built-in lifting drive mechanism, whose drive end is connected to the bracket to drive the bracket to move up and down. The track is located below the printing assembly. The forming platform is movably mounted on the track. This utility model replaces the previous gradually descending forming cylinder technology with a technology that controls the printing assembly to rise gradually through a lifting drive mechanism. During the printing process, the forming platform is only responsible for bearing the continuously increasing weight of the material layer. Therefore, the lifting drive mechanism does not experience the situation of continuously increasing force as the printing process progresses, as in traditional technologies. This allows for more precise control of the printing thickness and accuracy. Furthermore, unlike the high requirements of forming cylinder structure manufacturing, it effectively saves manufacturing costs.

This invention discloses a 3D printing platform leveling and printing quality monitoring system and method based on vision and laser fusion detection. The system includes a vision detection module, a laser ranging module, a fusion calculation module, an AI recognition and decision-making module, and a control feedback module. Both the vision detection module and the laser ranging module establish bidirectional communication connections with the fusion calculation module to match the timing of image and distance information acquisition. This application effectively solves the problems of insufficient accuracy and instability in traditional technologies. By constructing a collaborative detection structure through the vision detection module and the laser ranging module, a triangulation subsystem of laser and vision detection modules is formed, completely overcoming the inaccuracy problem of traditional probes on highly reflective surfaces or magnetic plates. Simultaneously, it avoids the interference of environmental temperature, humidity, and material properties on measurement accuracy, significantly improving the stability and accuracy of the detection.

This invention relates to the field of additive manufacturing technology, specifically to an optical expansion platform, additive manufacturing equipment, and manufacturing method thereof. The platform includes a drive system with multiple output ends, the movement directions of which include a first direction and / or a second direction, the first direction being perpendicular to the second direction. The multiple output ends are capable of synchronous and independent movement. Optical devices are configured as multiple optical path mechanisms, each disposed on one of the output ends of the drive system. The output ends of this application can move synchronously to achieve overall collaborative scanning of large areas of large-size parts, improving processing efficiency, and can also move independently to meet the specific or differentiated processing needs of parts in certain areas. This collectively overcomes the problems of poor quality in traditional large-format scanning and defects in splicing multiple small-format parts, achieving high-quality one-time forming of large-size parts.
