[Jessica] Is Soft On Robot Grippers

It is an old movie trope: a robot grips something and accidentally crushes it with its super robot strength. A little feedback goes a long way, of course, but futuristic robots may also want to employ soft grippers. [Jessica] shows how to build soft grippers made of several cast fingers. …read more

EL Wire Makes For A Great Faux-Neon Sign

Neon signs are attractive, but require specialised tools and skills for their manufacture. If you don’t have time to learn glass blowing and source the right gasses, you’re pretty much out of luck. However, EL wire can give a similar aesthetic, and with an off-the-shelf power supply it is easy …read more

Bearing-reinforced Stepper Tackles Hefty Axial Loads

These days, it’s common among us hackers to load a stepper motor with forces in-line with their shaft–especially when we couple them to leadscrews or worm gears. Unfortunately, steppers aren’t really intended for this sort of loading, and doing so with high forces can destroy the motor. Fear not, though. …read more

Acoustic Lenses Show Sound Can Be Focused Like Light

Acoustic lenses are remarkable devices that just got cooler. A recent presentation at SIGGRAPH 2019 showed that with the help of 3D printing, it is possible to build the acoustic equivalent of optical devices. That is to say, configurations that redirect or focus sound waves. One fascinating demonstration worked like …read more

3D-Printed Extension for Extreme Macro Photography Includes Lens Electronic Control

Macro photography — the art of taking pictures of tiny things — can be an expensive pastime. Good lenses aren’t cheap, and greater magnification inflates the price even further. One way to release a bit more performance from your optics comes in the form of an extension tube, which mounts …read more

3D Printing Glass

For most of us, 3D printing means printing in plastic of some sort — either filament or photo resin. However, we have all wanted to print in other materials — especially more substantial materials. Metal printers exist but they aren’t cheap. However, it is possible to print molds and cast …read more

A Better Embroidery Machine, With 3D Printing and Common Parts

In concept, an everyday sewing machine could make embroidery a snap: the operator would move the fabric around in any direction they wish while the sewing machine would take care of slapping down stitches of colored thread to create designs and filled areas. In practice though, getting good results in …read more

Clicky Signspinner Works Just Like A Retractable Pen

[u407]’s 3D printed Signspinner was created as a clean/dirty indicator for a dishwasher, and at its heart is a mechanism that works a lot like that of a retractable ballpoint pen. Every click of the plunger spins the circular label inside by one-quarter of a rotation. In [u407]’s case it …read more

Resin Printers are Now Cheaper, Still Kind of a Hassle

Your run-of-the-mill desktop 3D printer is based on a technology known as Fused Deposition Modeling (FDM), where the machine squirts out layers of hot plastic that stick to each other. But that’s not the only way to print a Benchy. One of the more exotic alternative techniques uses a photosensitive …read more

3D Printed Fan Filter Takes Cues from Costume Scene

This custom fan filter created by [Kolomanschell] is a clever application of a technique used to create wearable 3D printed “fabrics”, which consist of printed objects embedded into a fine mesh like a nylon weave. The procedure itself is unchanged, but in this case it’s done not to embed 3D …read more
