Abstract

The invention discloses a composite multi-material energy field constraint part additive manufacturing device based on surface exposure and a composite multi-material energy field constraint part additive manufacturing method. The energy field constraint part additive manufacturing device adopts surface exposure, and forming of a composite material and embedding of a functional part are achieved through switching of internal stations of the device. After one type of liquid composite material is formed, the material can be formed according to actual requirements, or another station can be switched to form other composite materials, before liquid tanks are switched, a formed part needs to be cleaned and dried, mutual influence between the materials is avoided, the operation is repeated in this way, and finally, additive manufacturing of a composite material energy field constraint part is achieved. According to the energy field constraint part additive manufacturing device using surfaceexposure, by adopting a rotating station with a simple structure, the equipment space is effectively saved, the actions among procedures are coherent, the forming time is saved, the cost is reduced, and the additive manufacturing device has a good application prospect in the energy field constraint part such as a marine sensor and a complex field antenna.

Description

technical field [0001] The invention relates to a three-dimensional printing technology, in particular to a device and method for additive manufacturing of composite multi-material energy field constraints based on surface exposure. Background technique [0002] With the continuous development of mechanical equipment technology, material science, biomedicine, clinical medicine and communication science and the continuous improvement of people's living standards, people pay more and more attention to the efficient application of various energy fields. The demand for special functional devices such as high-performance sensors and wearable medical equipment is becoming more and more intense, while compounding (composite material systems), structural and functional integration (mechanics + functions) and bionic intelligence (good matching and response to the human body) It is bound to become the development direction of this type of materials and devices in the future. However,...
