With the advent of the computer, mechanical typewriters have almost completely disappeared from everyday life. Nevertheless, maker projects continue to show that interest in mechanical word processing has not completely died out – even if the approach is often far removed from classic technology. A current example is provided by YouTuber and maker Toast, who has created a typewriter entirely of his own design using 3D printing.
The special feature lies not only in the use of additive manufacturing, but above all in the operating concept. Instead of a conventional keyboard, the device uses a rotary wheel to select letters. Once the desired letter has been selected mechanically, the user presses it vertically onto the paper. The ink does not come from a ribbon, but is transferred through classic carbon paper – a deliberate throwback to older technologies.
Toast had to develop several mechanical components to implement the function. These include a type lever mechanism that transfers the letters to the paper, as well as a feed system that controls the paper feed during writing. Toast’s decision in favor of the unconventional input concept is based on the practical difficulties of implementing a classic QWERTY keyboard with mechanical type arms for home use.
The project is an example of how 3D printing, basic mechanics and an experimental approach can be used to develop functional, albeit unusual, devices. Even if the practical use is limited, the design offers interesting insights into the interplay between additive manufacturing and mechanical design.
