Abstract

The invention provides a 3D printing pen, which comprises a penholder, a pen tip and a refill. An extrusion cylinder is arranged between the penholder and the pen tip, the extrusion cylinder is internally provided with an extrusion cavity, the extrusion cavity is communicated with the pen tip and is internally provided with a heater and a spiral conveying assembly. The spiral conveying assembly comprises a rotating shaft and helical blades, one end of the rotating shaft extends into the pen tip, and the other end of the rotating shaft is connected to a second driving motor, which is fixedly arranged in the penholder. The penholder is provided with speed regulation buttons and a switch button, the penholder is internally equipped with a first driving motor, a circuit board and a fan. The 3D printing pen provided by the invention firstly utilizes one motor to send the refill into the extrusion cavity, then heats and melts the refill by the heater, and then utilizes the other motor to drive the helical blades, so that the molten refill can be conveyed to the pen tip and is finally extruded by the pen tip. The 3D printing pen provided by the invention has the characteristics of simple structure, ingenious design, stable and reliable 3D printing effect, and easy implementation.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, and in particular relates to a 3D printing pen. Background technique [0002] 3D printing, also known as rapid prototyping, is a new type of industrial processing technology. For plastic materials, the principle of 3D printing is generally to melt the plastic and then spray it out. The sprayed material is cooled and solidified to form the desired shape. 3D printing systems for industrial processing are complex. The principle of 3D printing is applied to the paintbrush with a small structure, so that the paintbrush can realize the simple 3D printing function. The 3D printing pen not only increases the interest of the brush product, but also assists the design performance of the designer. However, since the overall size of the 3D printing pen is small, a reasonable arrangement of the functional areas of the 3D printing pen has a great impact on the quality and cost of the 3D printin...
