This Back to the Future picture of Marty & Doc at the clock tower in 1885 was made using HueForge. It requires 6 colors Black, Dark Gray, Brown, Light Gray, Beige, and White. I used all Matte colors for this print because the colors seem to blend well together. Matte also helps reduce stringing on the print, but you can use normal PLA if that is all you have. Please keep in mind depending on the brand and shade of your PLA your results may vary.

Print at 100% infill with a layer height of 0.08, the first layer needs to be 0.16, and a wall loop of 1.

I did not use a prime tower, it is not needed. This print should take about 3h11m if you use the 3mf settings.

Swap Instruction are as followed:

Start with Black

At layer #5 (0.48mm) swap to Dark Gray

At layer #10 (0.88mm) swap to Brown

At layer #13 (1.12mm) swap to Light Gray

At layer #16 (1.36mm) swap to Beige

At layer #19 (1.60mm) swap to white

Happy Printing!
