3D drawing pen

Abstract

The invention discloses a 3D drawing pen comprising a pen holder, a pen head and a pen core; the pen holder is internally provided with a battery box, a driving mechanism and a pen core cavity; the surface of the pen holder is provided with a switch; one end, close to the pen core cavity, of the pen holder is provided with a light source; the pen core comprises a light curing material storing chamber surrounded by a soft material and a discharging mouth made of a hard material; the discharging mouth is provided with a window; the storing chamber of the pen core is located in the pen core cavity; the discharging mouth is located in the pen head; the pen head is mounted at one end, close to the pen core cavity, of the pen holder through a connecting structure. The 3D drawing pen provided by the invention is simple in structure, realizes 3D printing in a manner that a battery allows a threaded rod to drive a light curing material to be subjected to extrusion feeding, is safe and convenient in use, at the same time, can change different-color pen cores and pen heads with different-shape discharge mouths according to the needs, and is more flexible in use process.

Description

technical field [0001] The invention relates to the field of 3D drawing, in particular to a 3D drawing pen. Background technique [0002] With the rapid development of 3D printing technology, 3D printing technology is more and more widely used in people's daily life. 3D printing pen is popular as a tool that can conveniently construct three-dimensional models. It can be used for graffiti Creating personalized 3D models can also cultivate the user's spatial imagination; the existing 3D printing pens can only use internal heating to extrude hot-melt materials as raw materials, and can only use linear plastics as raw materials. It has the following disadvantages: The available raw materials are single, and the scope of application is limited; the extrusion speed of raw materials is uneven, and heat dissipation needs to be considered, which increases the volume of the pen, which is inflexible in use, and there is a risk of burns to the user during use.
