ABS: Three Plastics in One

It would be really hard to go through a typical day in the developed world without running across something made from ABS plastic. It’s literally all over the place, from toothbrush handles to refrigerator interiors to car dashboards to computer keyboards. Many houses are plumbed with pipes extruded from ABS, and it lives in rolls next to millions of 3D-printers, loved and hated by those who use and misuse it. And in the form of LEGO bricks, it lurks on carpets in the dark rooms of children around the world, ready to puncture the bare feet of their parents.

Tiny Drone Racing Gates Use Up Those Filament Scraps

Drone racing comes in different shapes and sizes, and some multirotor racers can be very small indeed. Racing means having gates to fly though, and here’s a clever DIY design by [Qgel] that uses a small 3D printed part and a segment of printer filament as the components for small-scale drone racing gates.

The base is 3D printed as a single piece and is not fussy about tolerances, meanwhile the gate itself is formed from a segment of printer filament. Size is easily adjusted, they disassemble readily, are cheap to produce, and take up very little space. In short, perfect …read more

Bask In The Warm Glow Of DIY Incandescent Bulbs

With most of the apparatus and instruments we now take for granted yet to be developed, the early pioneers of the Electric Age had to bring a lot to the lab besides electrical skills. Machining, chemistry, and metallurgy were all basic skills that the inventor either had to have or hire in. Most of these skills still have currency of course, but one that was once crucial – glassblowing – has sadly fallen into relative obscurity.

There are still practitioners of course, like [2SC1815] who is learning how to make homemade incandescent light bulbs. The Instructable is in both English …read more

Tariff Expansion Set to Hit 3D-Printing Right in the Filament

Mere weeks after tariffs were put into place raising the cost of many Chinese-sourced electronics components by 25%, a second round of tariffs is scheduled to begin that will deal yet another blow to hackers. And this time it hits right at the heart of our community: 3D-printing.

A quick scan down the final tariff list posted by the Office of the US Trade Representative doesn’t reveal an obvious cause for concern. In among the hundreds of specific items listed one will not spot “Filaments for additive manufacturing” or anything else that suggests that 3D-printing supplies are being targeted. But …read more

Old LED Light Bulbs Give Up Filaments for Spider Web Clock

We love it when something common gets put to a new and unusual use, especially when it’s one of those, “Why didn’t I think of that?” situations. This digital clock with a suspended display is just such a thing.

The common items in this case were “filaments” from LED light bulbs, those meant to mimic the look of clear-glass incandescent light bulbs. [Andypugh] had been looking at them with interest for a while, and realized they were perfect as the segments for a large digital clock. The frame of the clock was formed from bent brass U-channel and mounted to …read more
