Business models for 3D printing services - Mini Project: Build & Apply

Business Models for 3D Printing Services

📖 Scenario: You are starting a 3D printing service business. To plan your business, you need to understand different business models used in the 3D printing industry.This project will guide you through creating a simple list of common business models, adding a filter to select models based on customer type, and then organizing the models for presentation.

🎯 Goal: Build a structured list of 3D printing service business models, filter them by customer type, and prepare the final list for sharing with your team.

📋 What You'll Learn

Create a list of business models with exact names and customer types

Add a variable to filter business models for 'individual' customers

Use a loop to select only the filtered business models

Add a final step to prepare the list for presentation

💡 Why This Matters

This knowledge is useful for business analysts, startup founders, and marketing professionals in the 3D printing industry.

1

Create the list of business models

Create a list called business_models with these exact dictionaries: {'name': 'On-demand printing', 'customer': 'individual'}, {'name': 'Prototyping services', 'customer': 'business'}, {'name': 'Mass customization', 'customer': 'individual'}, {'name': 'Manufacturing partner', 'customer': 'business'}

3D Printing

# Create the list business_models with the specified dictionaries
# Your code here

Need a hint?

Use a list of dictionaries with keys 'name' and 'customer'.

2

Add a filter for individual customers

Create a variable called target_customer and set it to the string 'individual' to filter business models for individual customers.

3D Printing

business_models = [
    {'name': 'On-demand printing', 'customer': 'individual'},
    {'name': 'Prototyping services', 'customer': 'business'},
    {'name': 'Mass customization', 'customer': 'individual'},
    {'name': 'Manufacturing partner', 'customer': 'business'}
]
# Create target_customer variable set to 'individual'
# Your code here

Need a hint?

Assign the string 'individual' to the variable target_customer.

3

Filter business models by customer type

Create a list called filtered_models that contains only the dictionaries from business_models where the 'customer' value matches target_customer. Use a for loop with variables model and an if condition.

3D Printing

business_models = [
    {'name': 'On-demand printing', 'customer': 'individual'},
    {'name': 'Prototyping services', 'customer': 'business'},
    {'name': 'Mass customization', 'customer': 'individual'},
    {'name': 'Manufacturing partner', 'customer': 'business'}
]
target_customer = 'individual'
# Create filtered_models list with models matching target_customer
# Your code here

Need a hint?

Use a for loop to check each model's 'customer' key and add matching models to filtered_models.

4

Prepare the final list for presentation

Create a list called model_names that contains only the 'name' values from each dictionary in filtered_models. Use a list comprehension.

3D Printing

business_models = [
    {'name': 'On-demand printing', 'customer': 'individual'},
    {'name': 'Prototyping services', 'customer': 'business'},
    {'name': 'Mass customization', 'customer': 'individual'},
    {'name': 'Manufacturing partner', 'customer': 'business'}
]
target_customer = 'individual'
filtered_models = []
for model in business_models:
    if model['customer'] == target_customer:
        filtered_models.append(model)
# Create model_names list with names from filtered_models
# Your code here

Need a hint?

Use a list comprehension to extract the 'name' from each dictionary in filtered_models.
