Most of us want our 3D prints to be perfect. But at Cornell University, they’ve been experimenting with deliberately introducing defects into printed titanium. Why? Because using a post-print treatment …read more Continue reading Defective 3D Printing for Great Strength
There’s an old joke about the Thermos bottle that keeps things hot and cold, so someone loaded it with soup and ice cream. That joke is a little close to …read more Continue reading 3D Printering: Water-Cooled Hotends
We all know that you can convert heat into electricity. Usually, you do that with some form of steam, but there are other methods, too, including thermocouples. If you’ve ever …read more Continue reading Power for Nothing and Your Kicks for Free
The quality of consumer-grade 3D printing has gone way up in recent years. Resin printers, in particular, can produce amazing results and they get less expensive every day. [Squidmar] took …read more Continue reading 3D Printer Showdown: $350 Consumer vs $73,000 Pro Machine
Have you ever heard of topological insulators? These are exotic materials where electricity flows only on the surface with very little loss. Now, according to IEEE Spectrum, scientists at Harvard …read more Continue reading Acoustic Switching Transistors: A new Kind of Electronics?
If you are old enough, you may remember that, for a time, almost every year was the year that home video was going to take off. Except it never was, …read more Continue reading Shelf Actualization
We’re no strangers to [Ivan]’s work and this time he’s building a relatively small CNC machine using extrusion, 3D printed parts, and a Makita router. The plans are available at …read more Continue reading Tiny CNC Cuts the Metal
When you think of a robot, you probably don’t think of a ball of underwater algae. But a team of university researchers used a 3D-printed exoskeleton and a ball of …read more Continue reading That’s No Moon… It’s an Algae Robot
Chinese researchers are reporting that applying an electric field to pea plants increased yields. This process — known as electroculture — has been tested multiple times, but in each case …read more Continue reading Better Farming Through Electricity
