How This STL Is Meant to Be Printed

Orientation:

Flat back on the build plate

Image/detail side facing UP

Print style:

Height-based color blending (HueForge-style)

Color logic:

Dark colors first, light colors last

Lighter layers sit on top and let light pass through

This STL does not use mesh separation or color regions.

All 16 colors are created by layer changes only.

2. Base Print Settings (Use These)

Use these settings regardless of slicer.

Nozzle: 0.4 mm

Layer Height: 0.08 mm ✅ (important)

First Layer Height: 0.20 mm

Infill: 100%

Walls: 2–3

Top Layers: 0

Bottom Layers: 0

Supports: OFF

Ironing: OFF

Print Speed:

Outer walls: 25–30 mm/s

Overall max: 40 mm/s

Material: PLA (matte preferred for dark colors)

3. How the 16 Colors Are Applied (This File)

This file is designed for 16 equal color bands.

Layer math

Layer height: 0.08 mm

Each color uses: 2 layers

Height per color: 0.16 mm

Total color height: 2.56 mm

First layer (0.20 mm) is just adhesion and does NOT count as a color

4. Exact Color Change Plan

You will insert a color change every 2 layers after the first layer.

Color order (BOTTOM → TOP)

You must follow this order:

Black

Very Dark Gray

Dark Gray

Charcoal

Dark Brown / Dark Blue

Medium Dark Brown / Blue

Medium Brown / Slate

Neutral Gray

Medium Light Gray

Light Gray

Cream

Ivory

Pale Yellow

Off-White

White

Natural / Translucent (optional highlight)

If you don’t have exact shades, keep the dark → light progression. That matters more than color names.

5. Where to Add Color Changes (Critical Part)

Step-by-step (works in ****, PrusaSlicer, OrcaSlicer, Bambu Studio):

Slice the STL

Open Preview

Switch to Layer View

Ignore Layer 1 (that’s the 0.20 mm first layer)

Starting at Layer 2, add a color change every 2 layers

Example:

Layers 2–3 → Color 1 (Black)

Layers 4–5 → Color 2

Layers 6–7 → Color 3

…

Final 2 layers → Color 16

Most slicers will show this as:

“Add color change at layer X”

or “Pause for filament change”

6. If You’re Using AMS / MMU

Load filaments in slot order = dark → light

Do not paint by face

Use height-based color changes only

Disable purge towers if possible (this model doesn’t need them)

7. After Printing (Lighting Setup)

For this STL to look right:

Use white LED backlighting

Distance from light to litho: 15–30 mm

Avoid RGB lights (they flatten contrast)

8. Common Failures (Avoid These)

❌ Printing light → dark (image looks muddy)

❌ Infill below 100%

❌ Layer height above 0.12 mm

❌ Glossy black filament (kills detail)

9. Quick Checklist

Flat back on bed ✔

0.08 mm layers ✔

16 colors, 2 layers each ✔

Dark → light order ✔

100% infill ✔
