Micro-angelo? This 3D-printed ‘David’ is just one mm tall

Abstract of the referenced paper at https://www.mdpi.com/2072-666X/11/1/6 :
Additive Manufacturing of Sub-Micron to Sub-mm Metal Structures with Hollow AFM Cantilevers
We describe our force-controlled 3D printing method for layer‐by‐layer additive micromanufacturing (µAM) of metal microstructures. Hollow atomic force microscopy cantilevers are utilized to locally dispense metal ions in a standard 3-electrode electrochemical cell, enabling a confined electroplating reaction. The deflection feedback signal enables the live monitoring of the voxel growth and the consequent automation of the printing protocol in a layer‐by‐layer fashion for the fabrication of arbitrary‐shaped geometries. In a second step, we investigated the effect of the free parameters (aperture diameter, applied pressure, and applied plating potential) on the voxel size, which enabled us to tune the voxel dimensions on-the-fly, as well as to produce objects spanning at least two orders of magnitude in each direction. As a concrete example, we printed two different replicas of Michelangelo’s David. Copper was used as metal, but the process can in principle be extended to all metals that are macroscopically electroplated in a standard way.

Pretty amazing. Just think what it will be like in another 10 years, plus you'll be able to pick one of these up from Creality for a couple of hundred instead of 250K. The filament I'm using right now is 1.75mm in diameter. :roll:

Very impressive, reminds me of many years ago when IBM wrote "IBM" with single molecules.

Best and Happy Holidays,
Research is like a treasure hunt, you don't know where to look or what you'll find!
