easy

A. Marketplace platform

B. Subscription service

C. On-demand printing

D. Manufacturing contract

Solution

1. Step 1: Understand on-demand printing

   On-demand printing means customers pay each time they request a print, without ongoing fees.

2. Step 2: Compare with other models

   Subscription requires regular payments, marketplace connects buyers and sellers, manufacturing contracts are long-term deals.

3. Final Answer:

   On-demand printing -> Option C

4. Quick Check:

   Pay per order = On-demand printing [OK]

Hint: Pay only when ordering means on-demand printing [OK]

Common Mistakes:

• Confusing subscription with pay-per-use
• Thinking marketplace means direct printing
• Mixing manufacturing contracts with simple orders

2. Which of the following is the correct description of a subscription model in 3D printing services?

easy

A. Customers pay a fixed fee regularly for access to printing services

B. Customers pay only when they print a single item

C. Customers sell their designs directly to other users

D. Customers rent 3D printers for personal use

Solution

1. Step 1: Define subscription model

   Subscription means paying a regular fee (like monthly) to use services anytime within that period.

2. Step 2: Eliminate other options

   Pay-per-print is on-demand, selling designs is marketplace, renting printers is a different model.

3. Final Answer:

   Customers pay a fixed fee regularly for access to printing services -> Option A
