Tensioning 3D Prints For Lightweight, Strong Parts

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 techniques to the prints, such as this method of adding tensioning systems on 3D printed trusses, you can reduce weight and make prints that are otherwise not remarkable incredibly strong.

The building 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 is strung along the interior of the truss from one end to another to give them strength and weight without weighing it down. The method works similarly to prestressed-concrete construction, but allows for lighter components and longer spans. The last point is particularly important, as this method will eventually be used to construct a 3D-printer where components are required 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 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.
