Origami-Inspired, Self-locking Structures With 3D Printing

Researchers recently shared details on creating foldable, self-locking structures by using multi-material 3D printing. These origami-inspired designs can transition between flat and three-dimension…

Printing In Multi-material? Use These Filament Combos

If one has a multi-material printer there are more options than simply printing in different colors of the same filament. [Thomas Sanladerer] explores combinations of different filaments in a fanta…

Need Many Thin Parts? Try Multi-material Stack Printing

Admittedly it’s a bit of a niche application, but if you need lots of flat 3D printed objects, one way to go about it is to print them in a stack and separate them somehow. An old(er) solution is t…

Make Multi-Material Resin Prints With A Syringe (And A Bit Of Patience)

Resin printing is a fantastic way to create parts, but multi-material printing isn’t really a possibility with resin. That is, unless you use [Cameron Coward]’s method for creating mult…

Automated Hotend Swapping For Less Wasteful Multicolor Printing

Multicolor printing on FDM machines can be tricky to get working flawlessly, and purging hotends when changing colors can end up wasting a lot of filament and material. To solve this problem for th…

Prusa XL Goes Big, But That’s Only Half The Story

For a few years now it’s been an open secret that Prusa Research was working on a larger printer named, imaginatively enough, the Prusa XL. Positioned at the opposite end of their product spe…

Enraged Rabbit Project Is A Filament Cocktail Special

As long as 3D printers have been around, it seems as though many of us have dreamed about nozzle-sharing solutions for multicolor 3D prints. Just because Prusa’s MMU has had the spotlight for…

Toolchanging Printers Get A Nozzle Hanky Like No Other

When it comes to toolchanging 3D printers, idle nozzles tend to drool. Cleaning out that nozzle goo, though, is critical before switching them into use. And since switching nozzles can happen hundr…
