Smart Formulation of cBN (Cubic Boron Nitrite) Slurry for Insert Fabrication: A Bayesian Optimization Approach in Vat Photopolymerization

Sampath Kumar R

Abstract: Vat photo polymerization (VPP) is a high-precision additive manufacturing technique for producing complex ceramic components. It requires a high ceramic content to reduce shrinkage and improve mechanical integrity, but also raises the slurry's viscosity, compromising printability. Traditional trial-and-error methods are time-consuming and costly, especially for high-value materials like cubic boron nitride (cBN). Bayesian optimization, an AI-driven technique, was used to guide experimental formulation, resulting in a VPP-suitable cBN slurry with 69 vol. % ceramic content in fewer than 40 iterations. This demonstrates how integrating AI with materials development can accelerate optimization, reduce waste, and advance high-performance ceramics in additive manufacturing.
