Have lots of goldfinches at our birdfeeder. Thought I'd try a “stained glass” version of one. It was a lot harder than I thought, but it came out okay.

I used HueForge Lithophane Blending Type and an AI created image to make this “stained glass" Goldfinch print in TWO parts. The first part has just the blues and black of the foreground. The second part blanks out parts of the bird and provides the reds and yellows for the background.

Both parts have very thin base layers, so special care is needed to remove them from the print bed. It is probably best to cool them completely before trying.

When joining the two parts be sparing with the adhesive, especially in the lighter parts. The adhesive will change the colors if it is not behind the black or red parts. I just used some around the black parts and around the very edge to keep the glue from showing. If spread thin and uniformly, it should not show too much.

I used 0.08mm layers to speed printing with minimal lose in detail.

Part 1

Project: GoldFinch_Part_1_v2.hfp
Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm

The Model is 150x150mm in size
You may print at higher layer heights below the Min Depth of 0.16mm
The Max Depth is 1.4mm and the Actual Depth is 1.4mm

Filaments Used:
PLA PolyLite Natural Transmission Distance: 21
PLA Overture Blue Transmission Distance: 4.2
PLA HueForge Navy Blue 2.2 Transmission Distance: 4
PLA 3D Solutech Black Transmission Distance: 0.4
This print uses 4 unique filaments

Swap Instructions:
Start with Natural
At layer #2 (0.24mm) swap to Blue
At layer #8 (0.72mm) swap to Navy Blue 2.2
At layer #11 (0.96mm) swap to Black for the rest.

Part 2:

Project: Goldfinch_Part_2_v2.hfp
Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm

The Model is 150x150mm in size
You may print at higher layer heights below the Min Depth of 0.16mm
The Max Depth is 1.9mm and the Actual Depth is 1.9mm

Filaments Used:
PLA PolyLite Natural Transmission Distance: 21
PLA BambuLab Matte Lemon Yellow Transmission Distance: 4
PLA PolyTerra Army Red Transmission Distance: 0.3
PLA Overture Red Transmission Distance: 4.8
This print uses 4 unique filaments

Swap Instructions:
Start with Natural
At layer #2 (0.24mm) swap to Lemon Yellow
At layer #17 (1.44mm) swap to Army Red
At layer #18 (1.52mm) swap to Red for the rest.

If substituting filaments, pick ones with the closest TD values. Use a Natural white, if possible. Otherwise, pick the one with a TD > 10 to minimize the color change it will cause.
