Description

Technical Field

[0001] The utility model belongs to the technical field of three-dimensional printing pens, and in particular relates to a particle material three-dimensional printing pen. Background Art

[0002] A 3D printing pen is a pen with printing function. It can draw on the surface of an object or in the air. It is often used in education, design, restoration, cultural creation and other fields. At present, the 3D printing pens on the market use a molten deposition process, using an extrusion roller to feed the filament into the pen tip, heat it, and then extrude it out of the nozzle. During use, once the extrusion roller feeds all the filament, it is very easy to cause the front and rear filaments to be unable to connect and become blocked. Therefore, in the process of painting, you need to always pay attention to the remaining length of the filament. When there is only a small section of filament left, the material must be removed from the printing pen, which is not only inconvenient to operate, but also the material cannot be fully utilized.

[0003] The granular material 3D printers currently on the market have the characteristics of fast printing speed, flexible material replenishment, and a wide range of material choices. However, since their extrusion mechanism uses a spiral push rod, the print head is large in size and weight and cannot be directly applied to printing pens.
