Description

A blade mold printing table based on 3D printing technology

technical field

The invention relates to the technical field of wind blade manufacturing, in particular to a blade mold printing table based on 3D printing technology.

Background technique

Wind energy is one of the most promising resources in terms of sustainability and reliability, but the turbine technology used is still imperfect. Blades are the key components of wind turbines. Their good design, reliable quality and superior performance ensure the normal operation of the unit, and also determine the power generation performance and power of the wind turbine. The size of the average turbine blade means testing and prototyping can be prohibitively expensive and time-consuming.

3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and others. The prototyping phase of new turbine blades can be drastically shortened using 3D printing technology. Traditional methods for making molds are time-consuming and labor-intensive, and each new model prototype will take around 16 months to complete before the blades can finally be built and tested on them. 3D printed molds cut that time down to just three months.

In order to manufacture blade molds, Sandia National Laboratories cooperated with Oak Ridge National Laboratory, a leader in 3D printing, and TPI Composites, the largest independent manufacturer of wind turbine blades in the United States, to develop the first wind turbine manufactured by 3D printing molds. The huge blade of a single machine, and thus won the 2018 National Technology Focus Award of the Federal Laboratory Alliance for Technology Transfer. With the advancement of science and technology, the blade mold production scheme based on 3D printing technology is becoming more and more perfect. However, the defects of 3D printing technology determine that it still cannot completely replace the traditional production method for mass production. The prototype design stage of the new turbine blade is convenient for designers to adjust and redesign the parameters of the blade according to the printed prototype mold. Existing 3D printing of blade molds is usually carried out in a laboratory, and the design process, printing process, transportation process, and testing and feedback process are all carried out independently, which affects the continuity of the experiment.
