Consumable material drying device of 3D printer

Abstract

The invention relates to a consumable material drying device of a 3D printer. The consumable material drying device comprises a printer body. A fixing piece is arranged on one side of the printer body. A consumable material coiling block is arranged on the fixing piece. A drying box is arranged on one side of the printer body. A feeding hole is formed in one side of the lower end of the drying box, and a discharging hole is formed in the other side of the upper end of the drying box. A guiding wheel is arranged in the drying box. A thermal insulating layer is arranged on the inner wall of the drying box. Heating plates are arranged on the side walls of the thermal insulating layer. A plurality of temperature sensors are arranged in the drying box. When the consumable material drying device is used, a consumable material enters from the feeding hole and winds around the guiding wheel to stretch out of the discharging hole. The consumable material is heated through the heating plates, and the consumable material is rapidly heated. By means of the temperature sensors, the stability of the temperature in the drying box can be ensured, drying of the consumable material is accelerated. The 3D printing consumable material only needs to be dried at a time or does not need to be dried, and the influence of the high temperature on the performance of the consumable material during drying is reduced.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a drying device for consumables of a 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive material to create three-dimensional objects. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. [0003] At present, the hopper of the 3D printer is set open, and it is impossible to isolate the air and moisture. The water absorption of the consumables has a significant impac...

AI Technical Summary

Problems solved by technology

This method is only suitable for the printing process of small parts. As the consumables stay in the air longer, their water absorption will increase, and the impact on the final printed parts will be greater. Therefore, it is not suitable for printing large parts for a long time.

[0005] In addition, frequent thermal drying of the consumables will have an adverse effect on the performance of the consumables, and the 3D printer needs to be readjusted and reset when replacing the consumables, which is time-consuming and laborious and will also affect the service life of the printer.
