Many modern desktop 3D printers include the ability to print in multiple colors. However, this typically only works with a few colors at a time, and the more colors you can use, the higher the machine’s cost and complexity. However, a recent technique allows printers to mix new colors by overlaying thin sheets of different […]
All the cool new 3D printers have tool-changing heads. Instead of multiplexing filament through one hot end, you simply park one hot end and pick up another. Or pick up a different tool, depending on what you need. There are many advantages to a system like that, but one disadvantage: cost. [Ultimate Tool Changer] has […]
Tool changing 3D printers are hot. The idea is that instead of switching filament, you swap out hot ends or other tools. That isn’t a new idea. However, most tool changers are expensive. [Engineers Grow] has one that is simple and inexpensive, relying on the printer’s own motors and some clever mechanics. The first step […]
Tool changing on 3D printers is hot right now, and it’s going to be really interesting to see the ideas that reliable tool changing lets people try out. One such idea is having the 3D printer use a marker to label the enclosure and buttons it just 3D printed. The 3D print shown is an […]
