摘要： A method of dynamically adjusting lifting parameter applied to a stereolithography 3D printer (2) is provided. The method is to retrieve a printing area value of each layer of slice physical models (42, 43) and a corresponding lifting parameter after completion of printing this layer of the slice physical model (42, 43), and lift a curing platform (24) of the stereolithography 3D printer (2) according to the lifting parameter for peeling this layer of slice physical model (42,43) from a material tank (23) and spending a continuous time corresponding to the lifting parameter, the continuous time is not less than a backfilling time of light-curable materials (41). Therefore, the time of 3D printing can be effectively reduced, and the efficiency of 3D printing can be improved as well.

摘要： A 3D printing method is provided. A stereolithography 3D printer (2) selects one of multiple layers of print data sequentially, makes a modeling plane be a default thickness (h) away from a material tank (23), irradiates heading to the modeling plane according to the selected layer of the print data for printing one layer of slice physical model (421-422, 431-433), makes the modeling plane detach from light-curable materials (41) in the material tank (23), rotates the material tank (23) for making an angle difference between angles before and after rotation be within a default angle interval, and performs above steps repeatedly until completion of a 3D physical model.

摘要： Disclosed are a 3D laser printer and its operation method. The 3D laser printer (10) includes a body (1), a powder paving mechanism (2), a mobile preheating mechanism (3) and a laser module (4). The body (1) has a chamber (11), a carrying platform (12) disposed in the chamber (11), and a feeding machine (13) and a construction machine (14) capable of descending and ascending with respect to the carrying platform (12). The powder paving mechanism (2) is accommodated in the chamber (11) and capable of moving reciprocately between the feeding machine (13) and the construction machine (14). The mobile preheating mechanism (3) is accommodated in the chamber (11) and capable of moving reciprocately in at least one of the feeding machine (13) and construction machine (14). The laser module (4) is configured to be corresponsive to the construction machine (14). Therefore, non-heat resistant components such as a color printer head and a motor can be installed into the chamber (11) directly to achieve the effects of diversified function and simple installation.
