Problems solved by technology

[0003] In order to solve the above problems, there are currently two solutions: one method is to reduce the printing speed, prolong the printing time, and allow time for the heat loss of the material, and this method makes the printing efficiency very low; A cooling fan is installed next to the print head to cool down the surface of the printed model material at any time. Although it can avoid the problem of thermal softening and deformation when printing small model shapes, but during the printing process, the fan cools down when the model is laid on a flat surface, and printing will occur. The bonding between the finished upper layer and the printing layer being printed is not firm and easy to crack

Abstract

The invention relates to the technical field of FDM printing moulds, in particular to a device for printing model cooling automatic controlling in the FDM printing process. According to the device, a timely-cooling model material is provided, and it is ensured that a model is not cracked, softened, collapsed and deformed in the FED printing process. According to the technical scheme, the device for printing model cooling automatic controlling in the FDM printing process comprises a cooling fan, a temperature sensor, a temperature controller, a PLC, a master controller and a relay; and the temperature sensor is in electric connection with the temperature controller, the temperature controller is in electric connection with the PLC, the PLC is in electric connection with the master controller, and the relay is in electric connection with the cooling fan. The device for printing model cooling automatic controlling in the FDM printing process is applicable to the field of FDM printing.

Description

Technical field [0001] The invention relates to the technical field of FDM printing molds, in particular to a device for automatically controlling the cooling of a printing model during the FDM printing process. Background technique [0002] In recent years, 3D printing technology has developed vigorously. Among them, printers based on FDM (melt extrusion) technology are very popular in the printer market due to their fast forming speed, low forming material price, and simple technology. However, during the printing process of the current FDM printers on the market, the small part of the printed model is printed on the periphery for a long period of time due to the print head. The heat of the material here cannot be dissipated in time, causing the model to soften and collapse. Eventually the model was scrapped. Therefore, realizing material cooling is one of the difficult problems that 3D printers need to solve. [0003] In order to solve the above problems, there are currently t...
