The video tutorial introduces the color painting feature for multi-color 3D printing, detailing various tools like the circle, sphere, triangle, height range, fill, and gap fill tools. It provides tips for efficient multi-color printing, such as managing filament changes and printing multiple models simultaneously. Advanced techniques include assembling models from single-color parts and optimizing orientation to save time and filament. The next video will cover more examples and tips for multi-color projects.

What is the first step to start painting a model for multi-color printing?

• Select the model in the 3D viewer

• Adjust the printer settings

• Click on the paint bucket or color painting tool

• Choose the color palette

Which tool allows you to draw on the surface of your model with a selected color?

• Height range tool

• Circle tool

• Triangle tool

• Sphere tool

What does the sphere tool do?

• Fills an entire surface

• Paints by layer heights

• Colors everything within a sphere

• Fills individual triangles

Which tool is used to fill gaps left after hand painting?

• Gap fill tool

• Circle tool

• Fill tool

• Height range tool

What is a consequence of multi-color printing on print time?

• It depends on the model size

• It increases print time due to filament changes

• It reduces print time

• It has no effect on print time

How can you save on filament when doing multi-color prints?

• Print models in multiple parts and assemble them

• Print models in a single color

• Reduce the number of filament changes

• Use a larger print bed

What is a benefit of adding additional benches to the build plate?

• It reduces the number of filament changes

• It increases the print speed

• It improves print quality

• It has the same number of filament changes
