Educational 3D printer is a kind of rapid prototyping technology, also known as additive manufacturing. A technique for constructing objects in a manner. It 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. It can ont only teach studetns 3D printing technology works and its application in real-word scenarios such as simplifying industrial processes, but also improve students’ creativity and design skills.
