Over the last decade, desktop 3D printers are a far cry from what they were. 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. By adding other building techniques like this method to add tensioning systems, 3D-printed trusses become stronger and lighter.
Build from [Jón Schone] The following are some examples of how to use Proper Printing The truss is made up of modular printed sections that can be joined together to form structural components with any length. Kevlar is strung along the interior of the truss from one end to another to give them strength and weight without adding any additional weight. This method is similar to the construction of prestressed cement, allowing for stronger components, longer spans and less building material. It also allows lighter components. The last point is particularly important, as this method is intended to be used for a future 3D printer that will require components to be strong and light. In this build it’s being used to make a desk lamp with a hinged joint.
Other innovative 3D Printer Builds [Jón] Has a lot of interesting designs. From this dual extrusion to this 3D printed passenger vehicle wheel. 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.
