3D printing pen

Abstract

The invention discloses a 3D printing pen. An energy storing device is arranged at the top of a printing pen body, a spring is arranged inside the energy storing device, a spring limiting groove is formed in the outer side of the spring, a piston is arranged at the bottom of the spring, a material tank is arranged at the bottom of the piston, a shell is arranged on the outer side of the material tank, a second thread is arranged at the top end of the shell, a connecting piece is arranged on one side of the shell, and a clamping block is arranged at the top end of the connecting piece; a firstthread is arranged on the inner side of the clamping block, a fifth thread is arranged on the outer side of the first thread, a third thread is arranged on the inner side of the fifth thread, and a feeding pipe is arranged on the inner side of the third thread; and a fourth thread is arranged at the bottom end of the feeding pipe, and a pen head is arranged on the outer side of the fourth thread.According to the 3D printing pen, the second thread is arranged at the top end of the shell, the shell is connected with the energy storing device through the second thread, and the 3D printing pen is firm, simple, easy to operate and convenient to mount, demount and overhaul.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a 3D printing pen. Background technique [0002] 3D printing pen is a new type of electronic brush tool that uses PLA and ABS plastics to paint. It can not only paint on any surface such as traditional paper, desktop, wall, etc., but can even paint directly in the air. In addition, due to the materials it uses It is extracted from starch, which is not only safe and non-toxic, but also has the physical characteristics of turning two-dimensional images into three-dimensional objects. Most of the 3D printing pens currently used are driven by electric devices, which are not only complicated in structure and troublesome, but also easy to print. It affects the printing accuracy. In addition, most 3D printing pens are integrally formed, and the pen head cannot be replaced, which greatly limits its scope of application. [0003] Therefore, it is necessary to design a 3D pr...
