What innovation made complicated products easy to make?

The advent of modular design and 3D printing significantly simplified the production of complicated products. Modular design allows for products to be broken down into interchangeable parts, making assembly and customization easier. Meanwhile, 3D printing enables rapid prototyping and on-demand manufacturing, reducing the complexity and cost associated with traditional production methods. Together, these innovations have streamlined the creation process, making it more accessible for designers and manufacturers alike.
