Painting models in slicer in 3D Printing - Mini Project: Build & Apply

Painting Models in Slicer

📖 Scenario: You are preparing a 3D model for printing and want to add colors to different parts of the model using your slicer software. This helps you visualize the final print and plan the painting process.

🎯 Goal: Build a simple step-by-step guide to paint different parts of a 3D model inside a slicer software by setting up the model, selecting colors, applying paint, and finalizing the painted model.

📋 What You'll Learn

Create a basic 3D model representation

Set up a color palette for painting

Apply colors to specific parts of the model

Finalize the painted model for preview

💡 Why This Matters

🌍 Real World

Painting models in slicer software helps visualize how a 3D print will look with colors before printing. It assists in planning multi-color prints or post-print painting.

💼 Career

Understanding how to paint models in slicer software is useful for 3D printing technicians, designers, and hobbyists who want to create colorful 3D prints or prototypes.

1

Create the 3D Model Structure

Create a dictionary called model_parts with these exact entries: 'body': 'unpainted', 'wheels': 'unpainted', and 'windows': 'unpainted' to represent parts of the 3D model.

3D Printing

# Create the model_parts dictionary with unpainted parts
# Your code here

Need a hint?

Use a dictionary with keys as part names and values as 'unpainted'.

2

Set Up the Color Palette

Create a list called color_palette with these exact colors as strings: 'red', 'black', and 'blue' to use for painting the model parts.

3D Printing

model_parts = {'body': 'unpainted', 'wheels': 'unpainted', 'windows': 'unpainted'}
# Create the color_palette list with 'red', 'black', and 'blue'
# Your code here

Need a hint?

Use a list with the exact color names as strings.

3

Apply Colors to Model Parts

Use the model_parts dictionary and assign colors from color_palette to each part exactly as follows: set model_parts['body'] to 'red', model_parts['wheels'] to 'black', and model_parts['windows'] to 'blue'.

3D Printing

model_parts = {'body': 'unpainted', 'wheels': 'unpainted', 'windows': 'unpainted'}
color_palette = ['red', 'black', 'blue']
# Paint the body red, wheels black, and windows blue
# Your code here

Need a hint?

Assign each part a color from the palette by updating the dictionary values.

4

Finalize the Painted Model

Create a variable called painted_model and assign it the model_parts dictionary to represent the final painted model ready for preview.

3D Printing

model_parts = {'body': 'unpainted', 'wheels': 'unpainted', 'windows': 'unpainted'}
color_palette = ['red', 'black', 'blue']
model_parts['body'] = 'red'
model_parts['wheels'] = 'black'
model_parts['windows'] = 'blue'
# Assign model_parts to painted_model
# Your code here

Need a hint?

Simply assign the updated model_parts dictionary to painted_model.
