The invention relates to a thermal environment control structure and method for a fused deposition process of a 3D printer. The thermal environment control structure comprises a 3D printing controller, and a melted extruding head, wherein a base is arranged in the melted extruding head, a servo wire feeding mechanism is connected to the base, the servo wire feeding mechanism is connected to a high-temperature extruding head through heat radiation and heat conduction wires, and a thermostatic heating block is arranged on the high-temperature extruding head, an annular light emitting plate is connected with the base through supports, the high-temperature extruding head extends out of the annular light emitting plate, the end of the high-temperature extruding head is higher than the lower surface of the annular light emitting plate, a thermal radiation luminescent tube array is uniformly distributed on the annular light emitting plate, the thermal radiation luminescent tube array is connected with a thermal radiation controller, and the thermal radiation controller can be used for independent control of each thermal radiation luminescent tube in the thermal radiation luminescent tubearray. The thermal environment control structure and method have the advantages of simple structure, reasonable scheme, good thermal environment control effects of a fused deposition key area, low comprehensive energy consumption, no need of cabin sealing and low cost, and are easy to popularize and apply in the 3D printing industry.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a thermal environment control structure and method for the fusion deposition process of a 3D printer. Background technique [0002] Fused Deposition Modeling (FDM) 3D printers are currently one of the most widely used types of 3D printers. It provides a low-cost and rapid processing method for 3D parts without molds. 3D printers using FDM technology combine resin, engineering Plastic and other plastic wires are melted at high temperature by the melting extrusion head, and then deposited layer by layer on the section of the three-dimensional part according to the numerical control path, and finally accumulate the desired three-dimensional shape. During the fused deposition process, the working chamber of most 3D printers is at room temperature, and only when printing the first few layers, it passes through the hot bed-the substrate with constant temperature heating function, to keep the...

Problems solved by technology

However, the thermal insulation cabin is not only heavy in structure, high in energy consumption, and high in cost, but also easily causes high-temperature aging of servo devices, electrical sensors, and signal lines in the cabin, reducing its service life and reliability

At present, in the field of FDM 3D printers, there is still a lack of a thermal environment control method that can efficiently control the thermal environment of the fusion deposition process, and does not require real-time sealing and insulation of the entire cabin environment.
