Anodizing aluminium is a process that reveals all slight imperfections on the surface of the metal. There cannot be any hairline scratches, any texture alterations or even fingerprints. The electrochemical process highlights all these even more. For most projects this is an obstacle. But it could also be an inspiration – mess up the surface intentionally.
Brush & anodize
The first stage of this method was the design of a 3D printed tool that oscillates in different ways to reliably control a brush patter on the surface of the metal. The design of the tool is our production secret, the sketch below kind of tells the story a little bit. The tool is motor driven and is capable of effectively decorating surfaces up to 1000 x 2000 mm. The anodizing here is hard silver and normal dark grey. These are some amazing surface finishes that have very unique organic yet still technical look and just await an application in a real project.
More or less random brush patterns.
The mostly automated brushing method produces different results based on type of tool used and the oscillation with which it hits the surface of the material. Metals have been tested the most but this vibration based method could surely work on many other materials as well.
The brush effect is done after the laser and can go over any perforations with ease.
