We’re no strangers to seeing translucent 3D printed parts: if you print in a clear filament with thin enough walls you can sorta see through the resulting parts. It’s not perfect, but if you’re trying to make a lamp shade or decorative object, it’s good enough. You certainly couldn’t print anything practical like viewing windows or lenses, […]
20 years ago, PCB production was expensive and required a multitude of phone calls and emails to a fab with significant minimum order restrictions. Now, it’s cheap and accessible online, which in addition to curtailing the home etching market has created significant new possibilities for home projects. Now that flexible PCBs are also readily available, […]
Normally when you think of a V8 engine you think of pistons driven by exploding fuel, pushing a crankshaft. [Miller’s Planet’s] version doesn’t use pistons, instead it uses solenoids along with a 3D printed crankshaft. The finished product would make a great science project or classroom demonstration of how a crankshaft converts a reciprocal linear […]
We’ve seen all sorts of 3D-printers on these pages before. From the small to the large, Cartesians and deltas, and printers that can squeeze out plastic, metal, and even concrete. But this appears to be the first time we’ve ever featured a paper-pulp extruding 3D-printer. It’s fair to ask why the world would need such […]
