Commercial 3D printers keep getting faster and faster, but we can confidently say that none of them is nearly as fast as [Jan]’s Minuteman printer, so named for its goal of eventually printing a 3DBenchy in less than a minute. The Minuteman uses an air bearing as its print bed, feeds four streams of filament […]
Many FDM filament dryers have a port through which you can guide the filament. This handy feature allows you to print from the spool without removing it from the dryer, saving time and limiting exposure to (moist) air. Unfortunately, these exit ports aren’t always thought out very well, mostly in terms of the angle with […]
With the newer generation of quick and reliable 3D printers, we find ourselves with the old collecting dust and cobwebs. You might pull it out for an emergency print, that is if it still works… In the scenario of an eternally resting printer (or ones not worth reviving), trying to give new life to the […]
We all love combat robotics for its creative problem solving; trying to fit drivetrains and weapon systems in a small and light package is never as simple as it appears to be. When you get to the real lightweights… throw everything you know out the window! [Shoverobotics] saw this as a barrier for getting into […]
Stripping and cutting wires can be a tedious and repetitive part of your project. To save time in this regard, [Red] built an automatic stripper and cutter to do the tiring work for him. An ESP32 runs the show in this build. Via a set of A4988 stepper motor drivers, it controls two NEMA 17 […]
You can buy all sorts of RC cars off the shelf, but doing so won’t teach you a whole lot. Alternatively, you could follow [TRDB]’s example, and design your own from scratch. The Lizard, as it is known, is a fun little RC car. It’s got a vaguely Formula 1-inspired aesthetic, and looks fetching with […]
Sometimes, you find yourself in need of a coil. You could sit around winding thousands of turns of copper wire yourself, but that would be remarkably tedious. Thus, instead, you might follow the example of [OJengineering] and choose to get a machine to do it for you. This build first popped up on on Reddit, […]
A treadmill-style bed can be a great addition to a 3D printer. It allows prints to be shifted out of the build volume as printing continues, greatly increasing the size and flexibility of what you can print. But [Ivan Miranda] and [Jón Schone] had a question. Instead of making a treadmill to suit a 3D […]
If you’ve got a popular 3D printer that has been on the market a good long while, you can probably get any old nozzles you want right off the shelf. If you happen to have an AnyCubic printer, though, you might find it a bit tougher. [Startup Chuck] wanted some specific sized nozzles for his […]
