Thought I would share this. Using Sequential printing with Multi Process has reduce the number of material changes required.
I use to print the objects one at a time. Now I print them in the same job and use pauses to change out the material. Only requires 3 changes during the job.
Now I start with Black, Change to White, to grey, then back to black.
The old way was:
Object 1 start with White, change to Black. finish
Object 2 continue with black change to white. finish
Object 3 continue with White change to grey. finish
then change back to White to start next batch.
