AI CAD tools are rapidly entering the 3D printing space, falling into four categories: plugin assistants, automated workflows, file inspectors, and text-to-STL converters. Inspectors automatically identify errors in CAD files, reducing the risk of geometric defects, and are expected to see the earliest widespread adoption. While text-to-STL tools generate rough models, they enable hundreds of millions of users to easily create simple items like jewelry or toys, significantly expanding consumer-grade 3D printing applications. Such tools could democratize 3D creation, moving it from 2 million experts to the general public, much like personal computers did. For the metal powder industry, a surge in non-professional users will drive demand for desktop-class 3D printing, though high-performance parts will still rely on traditional CAD design. Key factors to watch include the adoption rate of inspectors and the practical use of text-to-STL in the consumer market.
