Color gradient filament is fun stuff to play with. It lets you make 3D prints that slowly fade from one color to another along...

When one needs a spring, a 3D-printed version is maybe not one’s first choice. It might even be fair to say that printed springs...

Overhangs are the bane of the melty-plastic 3D printing world. Often, we try to avoid them with creative print alignments, or we compensate with...

We always look forward to CNC Kitchen videos. They are usually useful, but always carefully thought out and backed with experimental data. His...

What happens when an air filter for 3D printers gets designed by engineers with a passion for function, a refusal to compromise, and a...

Evaluating the performance of 3D printers and component upgrades is a more difficult than it may seem at first glance, and subjective observations can...

Multicolor printing on FDM machines can be tricky to get working flawlessly, and purging hotends when changing colors can end up wasting a lot...

The early days of FDM 3D printing were wild and wooly. Getting plastic to stick to your build plate was a challenge. Blue tape...

The first video from attempting to make a liquid piston engine was… well… the operative word is attempting. The latest video, though, which...

Most houses built in the US today are platform construction: skinny two-by-fours are stacked and layered to create walls with studs. Each floor is...

One of the issues with 3D printing is that when a print is done, you need to go back and pull the print off...

At this point, 3D printers are nearly everywhere. Schools, hackerspaces, home workshops, you name it. Most of these machines are of the extruded-filament variety,...
