A 3D-printed “drive-by-wire” micro mill for your desktop — April 15th, 2026 In the automotive industry, “drive-by-wire” means that a traditionally mechanical linkage, like a throttle cable, has been replaced by an electronic actuator. That can eliminate design constraints and even save money. SciFientist was able to apply those same drive-by-wire principles to this 3D-printed micro milling machine . Machine tools, including vertical mills, are usually either CNC, manual, or power-assisted. In that last scenario, there is usually a simple motor that rotates a lead screw, so the user doesn’t have to crank the handle a bunch of times to traverse long distances. The motor can feed more consistently than a person can as well. But this 3D-printed micro mill is different, because it entirely replaces the traditional manual cranks with motors and can only be controlled electronically — just like a drive-by-wire car.…
