Hybrid 3D printing technique produces liquid-filled objects

Ordinarily, if you want to make a 3D-printed liquid-filled object, you have to inject the liquid after the object has been printed. A new process, however, allows such items to be printed all in one step – and the technology could have some valuable ap… Continue reading Hybrid 3D printing technique produces liquid-filled objects

Plant-inspired printing tech creates self-folding paper structures

When plants perform movements, such as curling their leaves or twisting their stems, they do so by drawing water into the cellulose fibers in that part of their “body.” Scientists have now replicated that technique to produce self-folding paper structu… Continue reading Plant-inspired printing tech creates self-folding paper structures

No Need for Speed with This Arduino-Based Inkjet Printer

When it comes to computers, it seems like the only thing that matters is speed. The more the better, in general, and the same applies to peripherals. We want the fastest network adapters, the fastest video card, and the fastest printer. So why in the world would anyone intentionally build …read more

Inkjet-printed tattoo electrodes deliver long-term EEG measurements

European engineers have optimized a novel technology using temporary tattoo electrodes to record electroencephalography (EEG) brain activity. The technology is cheap, can be produced using an inkjet printer, and delivers EEG measurements as accurately … Continue reading Inkjet-printed tattoo electrodes deliver long-term EEG measurements

This Camera Captures Piezo Inkjet Micro-Drops for DIY Microfluidics

In microfluidics, there are “drop on demand” instruments to precisely deposit extremely small volumes (pico- or nano-liters) of fluid. These devices are prohibitively expensive, so [Kyle] set out to design a system using hobbyist-level parts for under $1000. As part of this, he has a fascinating use case for a …read more

Vintage Mini Inkjet Prints On-Demand ASCII Art

Readers of a certain age may fondly remember ASCII art emerging from line printers in a long-gone era of computing; for others, it’s just wonderfully retro. Well, when [Emily Velasco] found a vintage Kodak Diconix 150 inkjet at a local thrift store for $4, she knew what she had to …read more
