New angles and concepts in 3D printing are always welcome, and we haven’t seen anything quite like [Horn & Rhode]’s 3D prints that do not look anything like 3D prints, accomplished with an experimental tool called HueForge. The concept behind it is simple (though not easy), and the results can be striking when applied correctly.
3D prints that really don’t look 3D-printed.
The idea is this: colored, melted filament is, in a sense, not that different from colored paint. Both come in various colors, are applied in thin layers, and blend into new colors when they do so. When applied correctly, striking imagery can emerge. An example is shown here, but there are several more both on the HueForge project page as well as models on Printables.
Instead of the 3D printer producing a 3D object, the printer creates a (mostly) flat image similar in structure to a lithophane. But unlike a lithophane, these blend colors in clever and effective ways by printing extremely thin layers in highly precise ways.
Doing this effectively requires a software tool to plan the color changes and predict how the outcome will look. It all relies on the fact that even solid-color filaments are not actually completely opaque — not when printed at a layer height of 0.08 mm, anyway — and colors will, as a result, blend into one another when layered. That’s how a model like the one shown here can get away with on ..
