Orientation strategy for strength in 3D Printing - Mini Project: Build & Apply

Orientation Strategy for Strength in 3D Printing

📖 Scenario: You are preparing to 3D print a small mechanical part that needs to be strong and durable. The way you place the part on the printer bed affects its strength after printing.

🎯 Goal: Learn how to choose the best orientation for a 3D printed part to maximize its strength.

📋 What You'll Learn

Create a list of common 3D printed part orientations

Add a variable to represent the strength priority

Use a loop to evaluate each orientation's strength advantage

Select the best orientation based on strength considerations

💡 Why This Matters

🌍 Real World

Choosing the right orientation for 3D printing parts helps improve their strength and durability, which is important for functional mechanical components.

💼 Career

Understanding orientation strategies is useful for 3D printing technicians, product designers, and engineers who want to optimize printed parts for strength.

1

Create a list of 3D print orientations

Create a list called orientations with these exact string values: 'flat', 'upright', and 'angled'.

3D Printing

# Create a list called orientations with 'flat', 'upright', and 'angled'
# Your code here

Need a hint?

Use square brackets to create a list with the given strings separated by commas.

2

Add a strength priority variable

Create a variable called strength_priority and set it to True to indicate that strength is the main concern.

3D Printing

orientations = ['flat', 'upright', 'angled']
# Create a variable strength_priority and set it to True
# Your code here

Need a hint?

Use the exact variable name strength_priority and assign it the boolean value True.

3

Evaluate strength advantages of each orientation

Create an empty dictionary called strength_scores. Then use a for loop with variable orientation to go through orientations. Inside the loop, assign a strength score to each orientation in strength_scores as follows: 'flat' = 3, 'upright' = 1, 'angled' = 2.

3D Printing

orientations = ['flat', 'upright', 'angled']
strength_priority = True
# Create an empty dictionary strength_scores
# Use a for loop with variable orientation to assign scores
# Your code here

Need a hint?

Use an if-elif-else structure inside the loop to assign the correct score to each orientation.

4

Select the best orientation for strength

Create a variable called best_orientation and set it to the key in strength_scores with the highest value using the max() function with key=strength_scores.get.

3D Printing

orientations = ['flat', 'upright', 'angled']
strength_priority = True
strength_scores = {}
for orientation in orientations:
    if orientation == 'flat':
        strength_scores[orientation] = 3
    elif orientation == 'upright':
        strength_scores[orientation] = 1
    elif orientation == 'angled':
        strength_scores[orientation] = 2
# Set best_orientation to the orientation with the highest strength score
# Your code here

Need a hint?

Use the max() function with the key parameter to find the dictionary key with the highest value.
