The processing of sheet metal using conventional methods such as hydraulic presses and punching dies is efficient and widespread. However, the production of the required punching tools is often complex and costly. A recent video from the YouTube channel “Stick Shift Garage” shows how such tools can be created using 3D printing. The team used PLA+ with full infill to print individual stamps for embossing 1 to 2 mm thick sheet metal – including their logo.
The results in the video show that the technology is promising. After a few adjustments to the pressure of the press, precise and recognizable embossing was achieved. The PLA+ stamps lasted about a dozen uses before the first signs of wear appeared, but without completely failing. For a longer service life, other filament types such as PETG or materials reinforced with glass or carbon fibers could be an interesting alternative. The extent to which these options can compete with conventional CNC-manufactured metal tools remains to be seen.
In view of the fact that this was a first attempt without extensive prior knowledge, the experiment can be considered a success. The team has announced a further video for the future, in which improvements and new findings will be presented.
