Embodiment Construction
[0017] The specific embodiment of the present invention will be further described below in conjunction with the accompanying drawings, so as to better understand the inventive point of the present invention.
[0018] A 3D printing anti-warping temperature compensation and alarm method, comprising the following steps:
[0019] 1) Before starting 3D printing, preset a temperature range and a temperature difference value, and collect the actual temperature of the center of the printing bottom plate in real time. When the actual temperature of the center of the printing bottom plate is lower than the lower limit of the preset temperature range, blow hot air The method performs temperature compensation on the printing area, so that the temperature at the center of the printing plate rises until the actual temperature at the center of the printing plate reaches the lower limit of the preset temperature range, and the 3D printing model starts;
[0020] 2) During the process of 3D pri...

The invention discloses a temperature compensation and alarming method as well as heating system for preventing 3D printing edge warping. The heating system comprises an infrared temperature sensing module, a blower, an air heater band, a voltage regulation module, a control module and a power source module. The voltage regulation module comprises a thyristor zero-crossing trigger circuit unit and a heating circuit unit connected with the thyristor zero-crossing trigger circuit unit. The air heater band is connected in the heating circuit unit in series and is arranged at an air outlet of the blower. The signal output end of the infrared temperature sensing module and the blower are connected with the control module. The control end of the thyristor zero-crossing trigger circuit unit is electrically connected with the control module. The power source module supplies electricity to the infrared temperature sensing module, the control module and the thyristor zero-crossing trigger circuit unit. The problems that edge warping and irregular deformation of a model occur during 3D printing are solved, and meanwhile, the influence of the size of bottom plates of different 3D printers is avoided.
Description
technical field [0001] The invention relates to the field of printers, in particular to a 3D printing anti-warping heating system and a temperature compensation and alarm method for solving problems such as warping and irregular deformation of models during 3D printing. Background technique [0002] The reason for the warping of the model of the 3D printer: the warping is caused by cooling and shrinkage during printing of PLA / abs and other materials. The newly printed part has a higher temperature and shrinks slower during printing. The long shape shrinks faster, so the entire model is printed inconsistently due to shrinkage deformation, resulting in edge warping or irregular deformation. Different types of 3D printers have different anti-warping methods. The reason is that different 3D printers have different sizes of bottom plates, and the sizes of the heating plates they use will also be different. Contents of the invention [0003] The technical problem to be solved b...
