Shuttlecock with customizable structure and method for photocuring 3D printing of shuttlecock

Abstract

The invention discloses a shuttlecock with a customizable structure and a method for photo-curing 3D printing of the shuttlecock. The shuttlecock structurally comprises a shuttlecock head portion, anda shuttlecock skirt portion, wherein the shuttlecock head portion and the annular skirt portion are integrally formed by the same material through three-dimensional printing. After the structure is adopted, the shuttlecock is integrally formed by the same material through three-dimensional printing, it can be guaranteed that the shuttlecock head and the shuttlecock skirt of the shuttlecock are both of a symmetrical structure, the gravity center of the shuttlecock is located on the center line of the shuttlecock structure, and it is guaranteed that the flight path of the shuttlecock is stable.The photocuring 3D printing can show a complex hollow structure of the shuttlecock skirt, so that the shuttlecock conforms to aerodynamics, the flight path and flight speed of the shuttlecock can beclose to those of a shuttlecock with natural feathers; and the shuttlecock subjected to photocuring 3D printing is made of the same material, structures are in seamless connection, and the hitting resistance of the shuttlecock is greatly improved.

Description

technical field [0001] The invention relates to the field of additive manufacturing, in particular to a shuttlecock with a customizable structure and a method for photocuring 3D printing the shuttlecock. Background technique [0002] Photocuring 3D printing (Stereo Lithography Appearance, SLA or SL) mainly uses photosensitive resin as raw material, and utilizes the property that liquid photosensitive resin can be cured rapidly under the irradiation of ultraviolet laser beam. The photosensitive resin is generally in a liquid state, and it immediately causes a polymerization reaction under the irradiation of a certain wavelength of ultraviolet light (250nm ~ 400nm), and completes the curing. [0003] The specific photocuring 3D printing process is as follows: firstly slice the three-dimensional model of the pre-printed part, and then irradiate the surface of the photosensitive resin with light to cure it into a thin layer of solid, and the photocured photosensitive resin is ea...

AI Technical Summary

Problems solved by technology

Due to individual differences in natural feathers, the production process of natural feather shuttlecocks is more complicated, and because it is made of natural feathers, its durability is not high

In general, after 15 minutes of use, the shuttlecock made of natural feathers will lose hair, that is, the ball skirt cannot maintain symmetry, and the center of gravity of the shuttlecock will change, causing the flight trajectory to change.

[0005] There are also artificial feather shuttlecocks on the market to solve the problems of natural feather shuttlecocks, such as complex manufacturing process, not durable, not environmentally friendly

However, most artificial feather badminton designs are limited by the injection molding process. The structure design of the ball skirt is difficult to approach the aerodynamic natural feathers. Generally, the plastic ball skirts are hollow structures, so the airflow can pass through the plastic ball skirts.
