AI-driven design tools are transforming how products are conceptualized and developed in 3D printing. These tools leverage algorithms to optimize designs, enhance functionality, and reduce material waste.

What is generative design?

Generative design is a 3D CAD capability that uses AI to autonomously create optimal designs from a set of system design requirements. With generative design software, engineers can interactively specify their requirements and goals, including preferred materials and manufacturing processes, and the generative engine will automatically produce a manufacture-ready design. As a result, engineers can interact with the technology to create superior designs and drive product innovation more quickly.

Software like Autodesk Fusion 360 utilizes generative design, allowing engineers and designers to input parameters such as materials, manufacturing methods, and load conditions. The software then explores thousands of design alternatives, producing innovative solutions that might not be conceived through traditional methods. This approach not only leads to lighter, stronger components but also minimizes material usage.

Another powerful technique is topology optimization, where AI analyzes a design’s structure to determine the best material distribution. For instance, companies like nTopology are at the forefront, enabling designers to create complex geometries that maximize performance while minimizing weight, making it particularly beneficial for industries like aerospace and automotive.

AI tools are also enhancing the design process by providing real-time feedback. Tools like Siemens’ Solid Edge incorporate AI to suggest design changes based on performance metrics, allowing for quicker iterations and better final products.

Several startups have sought to improve AM through the use of AI. Printpal.io, for instance, uses AI to capture defects that occur during a 3D printing process. However, there is only one firm that has used AI to make the printing process itself actually work.

With $3 million in backing, 1000 Kelvin was founded by ex-Siemens employees who realized that no one was adequately addressing the problem. In turn, the Berlin-Los Angeles startup developed its AI-driven AMAIZE software to achieve first-time right 3D printing. Users simply upload a 3D model to the AMAIZE cloud, which analyzes the part. The tool, trained on millions of high-quality data points—including both simulated physics and actual measurements generated with Nvidia chips—identifies areas of a build that may encounter issues during printing. It then automatically corrects those errors, not by changing the design file itself, but by modifying the printer’s instructions. In that way, AMAIZE is an AI co-pilot for AM.

There’s no need to change the original 3D model based on intensive computer simulations. AMAIZE just pops out a file that tells the printer to adjust its laser power here, its scanning technique there, and, voila, the user has their desired part. In the case of a rocket launch provider that uses AMAIZE, the technology was able to cut the number of support structures for a critical component by 80 percent, which resulted in a cost savings of over 30 percent per part.

As industries increasingly adopt these advanced tools, we can expect faster prototyping, increased customization, and ultimately, more efficient production processes. The synergy between AI and 3D printing is not just a trend; it’s a fundamental shift in how we design and manufacture products for the future.
