Questions & Answers

Q: How does 3D printing bring software-like behavior to the physical world?

3D printing enables rapid prototyping, faster iterations, and the ability to quickly bring minimum viable products to market, allowing for customer feedback and iteration.

Q: What are the challenges of 3D printing in terms of design and materials?

Design literacy is a challenge for individuals looking to create their own designs. The need for materials that meet manufacturing constraints and R&D in the industry are also challenges.

Q: How does 3D printing impact the concept of seasonality and inventory management?

3D printing allows for on-demand production, eliminating the need for mass production and reducing waste. It also enables a long tail demand, making products available regardless of when they were designed.

Q: Can 3D printing become a mainstream technology for mass customization?

While 3D printing offers possibilities for mass customization, it still faces limitations in terms of material costs, volume, and production time. Progress is being made, but a shift to mainstream adoption may take time.

Summary & Key Takeaways
