The U1 can use four types of filament to produce a wider range of colors.
I recently discovered an interesting piece of software called “Lumina Studio,” which works on a principle somewhat similar to HueForge. However, instead of creating relief patterns, it generates flat designs. By layering filament of different colors, it can produce a wider range of colors. Just like the cross-sections shown below, the layers are stacked on top of each other. However, there is currently a limit: a maximum of 10 layers and a minimum of 5 layers.
After stacking 10 layers, this is the final result.
I also tried printing the same image using both 5-layer and 10-layer stacks. As a comparison, I think the 10-layer version renders skin tones better. The color transitions are also more refined, and the image’s contrast has improved to some extent
However, the biggest advantage of the U1 when printing overlaid colors is its speed. It took me 9 hours to print the first image using the U1. The sets below took 5 and 8 hours, respectively. If I had printed the first image using the AMS machine, it would have taken 12 hours.
