Architectural 3D printing applications

“

- [Instructor] 3D printing might enable much lower cost buildings and other structures. However, like any housing fabrication technique using it well requires knowledge, skill, and understanding of what a jurisdiction will sign off on for human habitation. In traditional concrete construction builders make a hollow mold called a form first. Typically this is made out of wood. Concrete is poured into the form and smoothed around any reinforcements. Quite complex shapes can be made this way like this precast concrete stairway. Here we see the mold which is filled with concrete and the final stair. 3D printing allows you to create something that would otherwise have required a mold by laying of similar materials, one layer at a time instead. For example, 3D printers can create most things that can be plastic injection molded. Each 3D print will take longer than making one copy with an injection mold but there's no need…
