If you want to build RC airplanes, you’ll need a way to make lightweight wings. 3D printing can work with foaming filament, but most 3D printers have limited build volume. A better method is to use a hot wire cutter to shape foam. Michael Rechtin’s CNC hot wire cutter automates that process across four axes, […]
When working with Styrofoam, a conventional CNC machine like a router or laser cutter just won’t do. However, as shown in Michael Rechtin’s excellent video below, a hot wire can carve foam like butter, creating custom wings for RC aircraft or whatever else you can dream up. Rechtin’s build uses a double gantry system to […]
You may have a 3D printer or other “digital” tools like a laser engraver or CNC router, but what if you want to work with Styrofoam? As How To Mechatronics demonstrates in his latest project, many of the same techniques used there can be implemented to make your own Arduino-powered hot wire cutter. This build […]
