Additive manufacturing of polishing pads

This invention describes a method for creating the specific material formulations used to make polishing pads. These pads have two distinct regions and are formed from a special blend of two different types of polymers that interlock to create a strong, flexible material. The method focuses on precisely mixing these polymers, controlling their ratio to achieve desired properties like strength and flexibility, and ensuring the final blend is very fluid, with a maximum viscosity of 20 centipoise.

Why it matters: Since 2023, advancements in AI-driven material design can better optimize IPN formulations, while multi-material additive manufacturing has matured.
