UT Researchers Used 3D Printing to Build a Tabletop Version of a $400 Million Semiconductor Machine

There is exactly one company in the world that makes extreme ultraviolet (EUV) lithography machines: ASML. Their high-NA EUV systems cost approximately $400 million each and are essential for manufacturing the most advanced semiconductors. Every cutting-edge chip — from Apple Silicon to NVIDIA’s AI processors — depends on access to this bottleneck.

Researchers at the University of Texas at Austin just demonstrated a tabletop alternative using volumetric 3D printing.

What EUV Lithography Does

Standard photolithography builds 3D nanostructures layer by layer: pattern one layer, process it, repeat. EUV extends this approach to extreme ultraviolet wavelengths to achieve finer features — but the sequential nature remains. Each layer is patterned individually, which means complex 3D structures require many sequential steps.

The UT approach inverts this. Rather than building structures one layer at a time, volumetric 3D printing creates the entire 3D nanostructure simultaneously. A single light source passes through stationary, self-assembling nanospheres, enabling all-at-once printing on a microscopic scale.

The Speed Advantage

The time difference is substantial. As Professor Chin-Hao Chang describes the conventional EUV process: “The actual printing might not take very long. But the processing can take days.”

The UT tabletop method operates on a scale of minutes. That’s not an incremental improvement — it’s a different order of magnitude for design-to-output cycles, which matters enormously in research and development contexts where iteration speed is the bottleneck.

Beyond Semiconductors

The implications extend past chip manufacturing. The research team identifies three additional application domains:

• Nanodrug development — creating 3D nanostructures for drug delivery systems
• Quantum computing — fabricating components that require nanoscale precision
• Novel material synthesis — enabling new material architectures not achievable with sequential lithography

The common thread: any field that requires 3D nanostructures at scale, at speed, without $400 million in capital equipment.

The Democratization Argument

The semiconductor research pipeline currently has a significant bottleneck: most academic institutions and smaller companies cannot access industrial EUV equipment. ASML sells to a handful of tier-one foundries — TSMC, Samsung, Intel. Everyone else is downstream.

If tabletop volumetric nanolithography can achieve research-grade nanostructure fabrication, it expands the number of institutions that can do frontier semiconductor research. That’s a structural change in who gets to work on advanced materials and chip architectures, not just a faster tool for the existing players.

So What?

This is early-stage research, not a commercial product. The UT system demonstrates feasibility of the volumetric approach — not parity with industrial EUV on all metrics. Resolution, yield, and scalability still need to be characterized at production conditions.

But the proof of concept matters: a tabletop system using 3D printing principles can create nanostructures that previously required a $400 million single-source machine. That opens a path for the technology to mature outside the ASML supply chain — and potentially gives the broader research community access to nanostructure fabrication that’s currently locked behind capital barriers.

For the 3D printing industry, it’s also a reminder that “3D printing” as a category is much wider than FDM printers making plastic parts. Volumetric nanolithography is the same underlying logic applied at a scale where individual features are measured in nanometers.
