3D conductive writing pen and writing method thereof

Abstract

The present invention relates to the liquid metal manufacturing field, and especially to a 3D conductive writing pen and the writing method thereof, and especially to a 3D conductive writing pen capable of realizing feedstock of various types of inks at the same time and the writing method thereof. A pen container is internally provided with a feed roller, a plastic wire and a channel for transferring metal ink, and the 3D conductive writing pen realizes the function of feedstock of various types of inks such as plastic and metal at the same time, so that the written 3D structure has plastic flexibility and portability and has metal conductivity; and moreover, the metal ink is filled with nanocrystalline metal particles to change the conduction performance of the writing lines. The writing pen can be directly configured for a 3D printer of the current popular common plastic or polymer wires so as to observably extend the application of the current device, fit for the fields of the teaching, field survival and military action and develop the application range of the routine conductive writing pen.

Description

Technical field [0001] The invention relates to the field of liquid metal manufacturing, in particular to a 3D conductive writing pen and a writing method thereof, and in particular to a 3D conductive writing pen that can realize simultaneous feeding of multiple types of inks and a writing method thereof. Background technique [0002] 3D (three-dimensional structure) writing pen is a portable writing pen that outlines three-dimensional structures with the rapid development of 3D printing technology. At present, the raw material of 3D writing pens on the market is thermoplastic plastic wire. When the thermoplastic wire is extruded from the pen holder for a few seconds, it will rapidly solidify, so that 3D structure can be directly written. The current 3D writing pen It is mostly used in the field of teaching and toys, mainly as teaching aids and toys. [0003] The disadvantage of this 3D writing pen is that the drawn lines do not have conductivity, which greatly limits its scope of...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to solve the relatively complicated spraying mechanism and ink processing of the existing 3D conductive writing pen due to the high surface tension of the liquid metal used, and the existing 3D conductive writing pen can only achieve a single ink operation, that is, only The ability to use conductive materials or insulating materials is not conducive to expanding the scope of practical applications
