DIY 3D Printing Uses low cost materials
Mark Ganter, Duane Storti and Ben Utela, from the University of Washington Department of Mechanical Engineering in Seattle, Washington, have developed a low-cost replacement for the materials their 3D printers use. AND, they've published their recipes.
Now materials costs drop from as high as $30 a pound to mere pennies. The result is that the UW has been able to open its rapid-prototyping shop to a wider variety of projects.
What's the new material? Powdered clay, mixed with sugar, maltodextrin or sometimes PVA. The fabjects are fired in a kiln just like any ceramic material.
Check out the recipe if you've built or are considering building a 3D printer.
