Update: added new Orca 3mf file (FullSpectrum Display Sign 12-Color BRYW.3mf) with better coloring (thx @jusdisgi )

This model is a dedicated showcase for the Full Spectrum fork of OrcaSlicer, created by Ratdoux. It is designed to demonstrate "Virtual Multi-Color" printing - achieving a massive spectrum of colors and gradients by dithering between multiple filaments.

While it can work on single-extruder machines, it shines on multi-toolhead printers like the Snapmaker U1. By using FullSpectrum, you can mix your loaded colors into entirely new shades and smooth gradients that go far beyond a simple tool swap.

Each letter in "FullSpectrum" is a separate object, allowing you to assign different mixed-color profiles to each one. This is the perfect first print to calibrate and see the dithering capabilities of the FullSpectrum slicer on your toolchanger.

Fast Print: Complete the test in under 2 hours at 0.08mm layer height.

Print Settings

• Layer Height: 0.08mm (Crucial for the best dithering/color mixing effect).
• Slicer: You must use the FullSpectrum OrcaSlicer Fork to achieve the mixed-color effect.

All credit for the development of this incredible technology goes to the creator, Ratdoux. This model was created to support and showcase the FullSpectrum project. Thank you, Ratdoux, for unlocking the true color potential of the 3D printing community!
