In the past ten years, desktop 3D printing has come a very long way. They’re now affordable for almost anyone, capable of printing in many diverse materials, and offer a level of rapid prototyping and development not feasible with other methods. However, because the machines can only print plastic, they have inherent limitations. However, adding other building techniques like this method to add tensioning systems 3D-printed trusses is a great way to save weight and increase the strength of prints.
Build from [Jón Schone] The following are some examples of how to use Proper Printing It consists of printed modules of truss that can be connected to create structural components of any length. Kevlar threads can be strung on the inside of the truss, from one end to the other, to add strength without adding weight. The threads are then tensioned at the one end. The method works similarly to prestressed-concrete construction, but allows for lighter components and longer spans. This is important because the method will be used to build a 3D Printer, where components must be both light and strong. In this build it’s being used to make a desk lamp with a hinged joint.
Check out these other 3D printers. [Jón] Has a lot of interesting designs. From this dual extrusion to this 3D-printed wheel for a passenger car, he has dozens. There’s all kinds of interesting stuff going on at that channel and we’ll be on the edge of our seats waiting to see the 3D printer he builds using this tensioned truss system.
