New Method Accelerates Color 3D Printing
A new slicer method for multi-color FDM 3D printing reduces the number of tool changes required. It works by rotating through a palette of colors each layer and adjusting filament flow or edge displacement to control color prominence, resulting in smoother gradients and faster prints. However, increasing the number of base colors can thicken apparent layer lines and steep walls may degrade the color blending effect.
- ▪The method rotates through a color palette each layer, adjusting filament amount or edge displacement to modulate color prominence.
- ▪It achieves smoother gradients and faster printing by requiring fewer tool changes than traditional multi-color approaches.
- ▪Adding more base colors increases the apparent layer height, e.g., a 3‑color print at 0.2 mm layer height appears as 0.6 mm.
- ▪Steep wall geometries can cause the color blending illusion to break down.

New Method Accelerates Color 3D Printing No comments by: Julian Scheffers July 23, 2026 Title: Copy Short Link: Copy Multi-color 3D printing is notorious for being difficult to get right. Even with modern printers, you often end up much using more filament (and tool changes) than you would for a single-color print. [YKG3D] shows us a new method of color printing that needs far fewer tool changes. Based on 2018 research, the new slicer rotates through its palette of colors each layer. Then, either by adjusting the amount of filament dispensed or by displacing the edges, the prominence of each color is adjusted.
