报告摘要：

Three dimensional printing (3D printing), also known as additive manufacturing, are now being studied and developed as a hot topic in many different fields. Civil engineering is no exception. 3D printing process is an additive manufacturing method from one dimensional dot/line to a two dimensional plane, then to a three dimensional object. In this lecture, the basic concepts and development path of 3D printing will be introduced first. Then the classification of 3D printing technique will be discussed. The focus of the lecture will be the techniques developed for civil engineering, including both directly deposition and selective reaction. Specifically, the D-shape printing, contour crafting and concrete printing. In civil engineering, the 3D printing is beginning to move from an architect's modelling to delivering full-scale architectural product, from a component of house such as piece of facades to a whole structure of a building. As a new hotspot in the architecture, three-dimensional concrete printing has great potential in rapid constructing and manufacturing of irregular geometric components. While 3D techniques is being fast developed, it is still facing a great challenge. One of the challenges is to obtain develop suitable materials for 3D printing in order to make the mortar be easily pumped or extruded, which needs the effort of materials scientist and engineers.

This talk will also introduce some other achievements of the presenter such as highly stretchable hydrogel and floating type wind turbine.
