Open type 3D printer based on hot melt accumulation

Abstract

The invention relates to the field of 3D printing equipment, in particular to an open type 3D printer based on hot melt accumulation. A detecting mechanism and a print head are arranged, a soft TPU line and a TPE line are freely and stably transferred, and when the flexible line is transferred, a sensitive device is arranged for probing the conditions that whether the line is plugged or not, whether the line is broken or not and whether the line is used up or not; a high-temperature-resistant throat pipe is arranged, and therefore a printing material with the higher heating degree can be used;a balanced printing sensor is arranged, the balance of the print head is monitored, and collision to a printed product is prevented; and a special cooling air nozzle is arranged, heat reduction is even, the printing freezing rate is increased, and stacking deformation is prevented. The open type 3D printer based on hot melt accumulation comprises a printing table, a Z-axis printing frame and an X-axis printing rack, wherein an X-axis guide rail of the X-axis printing rack is provided with the FDM print head, and the FDM print head includes a printing control module, a printing medium extrusion module, a print head body, a guide rail connecting frame wheel and a support connecting frame.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to an open 3D printer based on hot melt deposition. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a machine that can be used for rapid prototyping technology. Adhesive materials to create three-dimensional objects. At this stage 3D printers are used to manufacture products. The technology of printing in the direction of XYZ three-axis, and printing layer by layer through its own nozzle to construct the object. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will manufacture products layer by layer according to the program. There are various forms of stacking thin layers by 3D printers. The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. There are various forms of stacking thin layers, and there are various types...

AI Technical Summary

Problems solved by technology

[0003] Flexible materials such as TPU and TPE are commonly used in hot-melt deposition 3D printers. Because these wires are very soft, there will be a situation called jamming and plugging during use, causing the print head to continue printing, but the consumables are not. Extrude from the nozzle

Because most of the printing time of 3D printers is about several hours, and the large objects can reach hundreds of hours. This device is empty, and because the printing material is heated, the temperature will rise to more than 200 degrees Celsius, which will cause the print head to burn and cause a fire.
