Architected materials

3D printing that breaks the mold.

Dr. Mihaela Vlasea’s sophisticated approach to Additive Manufacturing ison an entirely new level.Dr. Vlasea has made it possible for additive manufacturing to achieve highly intricate geometries and specific porosities. By manipulating materials and studying the results with ZEISS X-ray microscopy, she creates parts with complex internal lattice structures that possess unique mechanical and thermal behavior not achievable in typical materials.

This precision is impossible with traditional machining, stamping or injection molding. Dr. Vlasea’s work has potential implications for the biomedical, aerospace, automotive, and transportation sectors, and her approach is already employed by several of those industries’ top manufacturers.

Realtime feedback

More data. Fewer scrapped parts.

One of the biggest challenges in Additive Manufacturing is consistency. It’s especially difficult when parts are tested only after manufacture. But with the insight of XRM, Dr. Mihaela Vlasea is pioneering AI-based computer models that identify flaws and improve consistency duringmanufacturing.

Using XRM to create a better understanding of in situ sensor data, she generates process intelligence to deliver real time feedback and greater transparency into the quality of the build, increasing the reliability and leading to fewer scrapped parts.

From predicting the location of pores, to identifying the factors that lead to flaws, Dr. Vlasea’s work has a profound impact on testing time, improved quality and the overall advancement of metal AM.

Speed to market

Fewer flaws in less time.

It can take up to a year to refine the process parameters for manufacturing new parts. But Dr. Mihaela Vlasea’s team have innovated Additive Manufacturing at the micro, meso and macro levels to gaininsights into the process, reduce error and speed up the cycle.

For example, in Laser Powder Bed Fusion, improper set up can result in faulty porosity, rendering an expensive sample part unusable. By combining microscopy with physics based models, Dr. Vlasea and her team are able to rapidly map the parameter space, zero in on ideal conditions and produce optimized parts.

ZEISS XRM technologygives Dr. Vlasea the ability to leverage more predictive power, thus improving the efficiency, quality and economics of precision parts made by additive manufacturing.
