3D printers are great for producing one thing, but if you need multiple copies, the workflow quickly starts to go downhill. The solution? Build a 3D printer with multiple print heads, capable of printing four objects in the same amount of time it takes to print one.
This build is an experiment for [allted]’ Mostly Printed CNC / MultiTool. It’s a CNC machine that uses printed parts and 3/4″ electrical conduit for the frame and rails. That last bit is the interesting part: electrical conduit is cheap, easy to acquire, available everywhere, and can be cut with a hacksaw. As far as desktop CNC machines go, it doesn’t get simpler or cheaper than this, and a few of these builds are milling wood with the same quality of a machine based on linear rails. It won the grand prize in the recent Boca Bearings contest, and is a great basis for a cheap and serviceable 2.5 or 3D CNC.
[allted] already has this cheap CNC mill cutting aluminum and engraving wood with a laser, showing off the capabilities of a remarkably cheap but highly expandable CNC machine. It’s a fantastic build, and we can’t wait to see more of these machines pop up in garages and workspaces.
