Digital twin solution provider and leading material designer to partner on premium content

Buffalo, New York – July 19, 2021 – Sentient Science and QuesTek Innovations have partnered to offer premium content that enables DigitalClone software-as-a-service subscribers to upgrade and gain access to the libraries of advanced materials designed by QuesTek.  The newly released material libraries include high-performance alloys that are widely used in aerospace and industrial applications: Ferrium C61, Ferrium C64, Ferrium M54, and Ferrium S53.  Additional models may also be included in future releases.

DigitalClone users that add this option to their subscription will gain the ability to evaluate and quantify the fatigue life benefits of QuesTek alloys for their specific applications – using models developed in collaboration with the material designer.  The physics-based SaaS modeling solution provides a low-risk, high-fidelity environment to fully explore the entire design space and highlight the effectiveness of innovative materials that support next-generation designs or lightweighting initiatives for existing designs.

“We have always admired the expertise of the team at QuesTek Innovations, and I look forward to this opportunity to work more closely together.  This agreement allows us to highlight a key use case for DigitalClone – the ability to digitally evaluate the benefits of using advanced materials like the Ferrium alloys,” says Stéphane Attal, CEO of Sentient Science.

QuesTek’s President, Jason Sebastian, said “QuesTek has long been impressed by Sentient’s technical achievements and market reputation, and we are excited to begin a formal collaboration together to ultimately enable higher performance designed systems.” He added “We view this as the first of several upcoming directional steps to increase digital access to QuesTek materials products and know-how, as a part of our broader strategy of leading the democratization and digitization of Integrated Computational Materials Engineering.”

QuesTek material libraries are available as an upgrade for existing DigitalClone for Engineering (DC-E) and DigitalClone for Additive Manufacturing (DC-AM) subscribers, as of 15 July 2021.  Upgrade fee will be added to annual subscription pricing.  Contact Sentient Science for details and pricing at

About DigitalClone

DigitalClone is a physics-based computational modeling and design framework that simulates the microstructure of different components and their behavior. It calculates internal stresses caused by different applied loading conditions, accumulates internal damages resulting in crack nucleation and propagation, and investigates the performance and life prediction. DigitalClone-AM accounts for various AM process parameters – such as laser power, scan speed, hatch strategy, layer thickness, and others – to generate highly accurate predictions of part-level distortion, residual stress, grain structure, and porosity. Sentient’s AM expertise include process and microstructure modeling of the AM build process, microstructure-based life prediction of AM components, in-process defect monitoring and correction, reliability-centered part design and optimization, and lifecycle cost analysis. Sentient’s AM fatigue life prediction capability has been demonstrated for several materials and components with high accuracy. Since 2015, Sentient Science has received a total of $5.6M in funding from the US DoD and NASA to continue to expand the company’s additive manufacturing capabilities.
