| summary |
This paper presents the design and construction of a 3D-printed thin bending-active formwork for shell. In order to use less scaffolding and make a dome with flexible material,3-D print is applied to the formwork. First step is form-finding . Two single -curved surfaces are used to fit the form found by Kanagaroo and then unroll them .Principle stress lines are also printed on the unrolled formwork to enhance it. However, the formwork with stress lines is hard to bend. So, bending-active simulation made by ABAQUS is also applied to find the best mesh pattern to bend. Bend the basic pattern first on the framework and then print Principle stress lines onto it. Karamba is used to simulate the deformation of the shell under gravity load. It is proved that grid made up of stress lines have the best performance The full scale prototype is made up of two pieces shell bent and tied together can stand steadily. Spring-back test shows that the second layer printed on the shell can help to provide deformation. |
