Make 3D-Modeling Child’s Play with a Can of Play-Doh

Posted on by

You need to replicate a small part on a 3-D printer, so you start getting your tools together. Calipers, rulers, and a sketch pad at a minimum, and if you’re extra fancy, maybe you pull out a 3D-scanner to make the job really easy. But would you raid your kid’s stash of Play-Doh too?

You might, if you want to follow [Vladimir Mariano]’s lead and use Play-Doh for accurately modeling surface features in the part to be replicated. Play-Doh is a modeling compound that kids and obsolete kids alike love to play with, especially a nice fresh can before it …read more

Using Lasagna to Make Cost-Saving Molds

Posted on by

Building a one-off prototype is usually pretty straightforward. Find some perfboard and start soldering, weld up some scrap metal, or break out the 3D printer. But if you’re going to do a production run of a product then things need to have a little more polish. In [Eric Strebel]’s case this means saving on weight and material by converting a solid molded part into something that is hollow, with the help of some lasagna.

What [Eric] walks us through in this video is how to build a weep mold. First, the solid part is cast in silicone. Using the cast, …read more

Your 3D Printer Could Print Stone

Posted on by

Most of our  3D printers print in plastic. While metal printing exists, the setup for it is expensive and the less expensive it is, the less impressive the results are. But there are other materials available, including ceramic. You don’t see many hobby-level ceramic printers, but a company, StoneFlower, aims to change all that with a print head that fits a normal 3D printer and extrudes clay. You can see a video of the device, below. They say with some modifications, it can print other things, including solder paste.

The concept isn’t new. There are printers that can do this …read more

SNES Micro Is A Pi Z Of Art

Posted on by

Clay is a shapeless raw material that’s waiting to be turned into awesomeness by your creativity. So is the Raspberry Pi. [Dorison Hugo] brought the two together in his artfully crafted SNES micro – a tiny retro gaming console sculpted from clay.

For his build, [Dorison] assembled two halves of a little case from sheet plastic, which both together have about the size of the components that will go inside the sculpture: a Raspberry Pi Zero and a USB hub. He then moulded clay on the outside of the two halves, using them as a scaffold for the actual case. …read more
