Lucas Pabarcius is an American entrepreneur and engineer who is a co-founder of Atum Works, a nanomanufacturing company building the world's first scalable 3D lithography foundry. Based in Mountain View, California, the company develops technology capable of printing arbitrary three-dimensional metal structures with submicron resolution, with applications in semiconductor manufacturing, biotech, sensors, and advanced materials.[1]
Career
Pabarcius co-founded Atum Works in 2024 alongside Malcolm Tisdale and Matteo Kimura. The company describes its mission as "gigascale nanomanufacturing" and positions itself as building "3D ASML" — a reference to ASML Holding, the dominant manufacturer of lithography systems used in semiconductor fabrication. Atum Works' technology enables the fabrication of multi-material three-dimensional structures at approximately 100 nanometer resolution on a wafer scale, which the founders believe could enable three-dimensional wiring between chips, potentially making AI hardware faster and more efficient.[2]
The company was founded by engineers with backgrounds at Caltech and NASA. Atum Works received NASA awards for Most Visionary Concept and Best Product Development. The company participated in the Y Combinator Spring 2025 batch and operates in the hard tech, 3D printing, and semiconductor sectors.[3]
As of early 2026, Atum Works has raised over $10 million in investment funding to scale its technology.[4]
Prior to founding Atum Works, Pabarcius worked at several technology companies including Apple and Moveworks, and was associated with Carnegie Mellon. He also worked with Kashikoi, another Y Combinator company.
In December 2025, Pabarcius and his co-founders were named to the Forbes 30 Under 30 list in the Science category for 2026, recognized for their work in nanoscale manufacturing and semiconductor technology.[5]
