An anti-drawing 3D printing pen with adjustable caliber

Abstract

The invention discloses an anti-wire-drawing 3D printing pen with adjustable diameter. The anti-wire-drawing 3D printing pen with adjustable diameter comprises a material guiding pipe, a hot melt chamber, a pen holder, throat pipes and a pen head. The hot melt chamber is formed in the bottom end of the interior of the pen holder, the material guiding pipe is disposed in the pen holder, the top endof the material guiding pipe extends to the top of the pen holder, the bottom end of the material guiding pipe is in communication with the hot melt chamber, and a heating pipe is arrange in the penholder of the outer side of the end, close to the hot melt chamber, of the material guiding pipe. The throat pipes are evenly spaced between the pen head and the pen holder, so that the surface area of the throat pipes can be utilized to increase the heat dissipation area of materials conveniently without affecting material circulation, and air can circulate between adjacent throat pipes, so thatthe printing pen is driven to move in the process of combining with the use of the printing pen; and the flow of the air between the throat pipes is further increased, the heat dissipation effect is improved, the solidification efficiency of the materials is improved, and the situation that the materials are excessively soft to affect the effect of printing in the process of printing is avoided.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to an adjustable caliber anti-drawing 3D printing pen. Background technique [0002] With the development of science and technology, 3D printing technology is more and more widely used in various fields. At the same time, 3D printing technology also appears in people's life in the form of more types of products, and 3D printing pen is one of them. Unlike 3D printers, which realize 3D printing through the movement of the printing nozzle driven by the mechanical arm, the 3D printing pen is controlled by human hands, and the 3D printing pen can realize three-dimensional painting according to the wishes of the person. That is to say, the user only needs to use the traditional paintbrush to operate It is possible to draw a three-dimensional pattern in a three-dimensional environment. [0003] At present, the nibs used in the existing 3D printing pens have a single function, and the ...

Problems solved by technology

[0004] The purpose of the present invention is to provide an anti-drawing 3D printing pen with adjustable caliber, so as to solve the problem that the existing 3D printing pen used in the above-mentioned background technology has a single function, and the same 3D printing pen cannot satisfy various needs of users at the same time. Creation needs, and the handwriting thickness, handwriting shape, and special functions of the pen tip are not easy to adjust during the use of the 3D printing pen. There will be part of the material overflowing, resulting in wire drawing, reducing the aesthetics of the work, uneven material delivery, and poor heat dissipation at the nib position
