DIY Solder Stencil from Soda Can

A method for creating DIY solder stencils from soda cans has been demonstrated, utilizing a 3D-printed tool for cutting and a fiber laser for precise hole creation.

Professionally made solder stencils are typically steel, but aluminum soda cans are a common alternative for hobbyists. The challenge lies in accurately creating the necessary holes.

A 3D-printed tool, similar to a pipe cutter, is used to cleanly slice the soda can. This tool gradually presses a utility knife blade into the can as it rotates, minimizing kinking and bending of the thin aluminum.

After removing the top and bottom of the can, it is cut down the side to form a flat sheet.

The hole pattern for the stencil is generated from PCB design software.

A fiber laser is employed to cut the stencil. Fiber lasers are effective for marking and cutting metal due to their wavelength, and they can cut the thin aluminum stencil very quickly.

Fiber lasers, once industrial tools, are now available as prosumer-level equipment. The demonstrated method uses an xTool F1 Ultra, a laser previously shown to be capable of creating PCBs by selectively removing copper.
