Pen-tip-replaceable 3D printing pen

Abstract

The invention provides a pen-tip-replaceable 3D printing pen. The pen-tip-replaceable 3D printing pen comprises a printing pen tip which is installed at the front end of a printing pen shell by meansof threaded connection; a connector socket is installed inside the front end of the printing pen shell; a connector matched with the connector socket is arranged at the tail part of the printing pen tip; a nozzle penetrates out of the top of the printing pen tip from the inside of the printing pen tip; and the tail part of the nozzle is connected with a conveying pipe through the connector. The pen-tip-replaceable 3D printing pen provided by the invention solves the problem that an original pen tip of the 3D printing pen is hard to dismount and replace, and can simultaneously satisfy the requirement that the printing shapes are different in a 3D drawing process. By adopting the pen-tip-replaceable 3D printing pen, a user can randomly, simply and rapidly replace the pen tips having variousfunctions on the same 3D printing pen, so more possibilities and higher flexibility are provided for 3D creation activities. If the pen tip is damaged or blocked, the user can easily implement the maintenance and replacement work, so the structural design of a product is optimized.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a 3D printing pen with a replaceable tip. Background technique [0002] At present, 3D printing pens mostly use acrylonitrile-butadiene-styrene plastic (ABS) filaments or polylactic acid (PLA) filaments as printing materials. The softening temperature of ABS filament is 200 degrees Celsius higher, and the softening temperature of PLA filament is also close to 200 degrees Celsius. When the softened printing consumables are extruded from the nozzle outlet, the nozzles with better heat dissipation performance will also be heated to a higher temperature by the softened printing consumables. [0003] Most of the nibs of the 3D printing pen protrude from the casing, so that the printing material can be extruded from the outlet on the nib and hardened on the printing medium. Some measures such as human body protection have been solved in the patented technology with application n...

AI Technical Summary

Problems solved by technology

At present, most of the nibs on the market are integrated, and the hook structure is generally used to connect with the pen body. It is easy to cause the nib to be difficult to disassemble and easy to be damaged due to material blockage or other reasons. The shape and the original non-detachable nib are improved
