Technical Field

[0001] This utility model relates to the field of 3D wax model printers, and more particularly to a 3D wax model printer that can be quickly air-dried. Background Technology

[0002] Ordinary printers used in daily life can print flat objects designed on a computer. 3D printers work on essentially the same principle as ordinary printers, differing only in the printing materials. Simply put, a 3D printer is a device that can "print" real 3D objects. There are many different technologies involved in 3D printing, differing in their forming methods and the raw materials used. Commonly used materials for 3D printing include nylon fiberglass, durable nylon, plaster, aluminum, titanium alloys, stainless steel, silver plating, gold plating, rubber, and wax.

[0003] In high-precision wax model 3D printing equipment, it is necessary to cool the already formed printing material faster to reduce the temperature inside the equipment during operation.

[0004] Therefore, it is necessary to design a 3D wax model printer that can dry quickly. Utility Model Content
