Laser fusion targets

Inertial fusion promises abundant clean energy, but experimental optimization of targets is slowed by limited precision, throughput, and process complexity of traditional manufacturing methods such as mandrel-based vapor deposition and droplet microencapsulation. Nanoscribe’s additive manufacturing (AM) solutions overcome these hurdles, considerably accelerating the path from initial concept to optimized fusion targets.

Print reproducible fusion targets with 2GL

Nanoscribe’s Two-Photon Grayscale Lithography (2GL®) is an advanced additive microfabrication technology that enables single-step production of inertial fusion targets with unmatched precision. It combines a dense shell with nanoscale surface smoothness and a high-resolution 3D-printed foam lattice to create intricate target architectures of low density. 

Researchers can now experimentally iterate new designs rapidly, potentially bypassing lengthy simulations and quickly identifying optimal geometries. By combining submicron resolution, highly reproducible structures, and unprecedented design freedom, these 3D-printed targets can directly contribute to improved fusion yield and clearer interpretation of implosion data. These capabilities position 2GL as the go-to method for labs and future fusion power plants, as it uniquely supports exploratory research and scalable, cost-efficient production.

The key benefits of high-resolution 3D printing

Nanoscribe accelerates faster fusion target optimization and scalability in fusion research with unmatched precision in ultrafast 3D printing. The specific application advantages of Two-Photon Grayscale Lithography in detail:

• Unlimited geometric possibilities: A wide variety of target geometries supports rapid experimental iteration and may reduce the need for simulation cycles.

• Precision for consistent results: Sub-micrometer resolution, shells with <10 nm surface roughness, and intricate nanoporous foam structures are printed simultaneously in a single fabrication step.

• Repeatable and deterministic production: Systematic CAD-to-target fabrication ensures reproducible print outcomes, enabling consistent, reliable performance data compared to traditional fabrication methods.

• Scalability through exponential speedup: Ongoing evolution of 2PP technology offers throughput gains reminiscent of Moore’s Law, potentially supporting future fusion powerplant viability.

• True single-step production process: No assembly, molds, or tooling required – minimizing variability, lead-time, and cost.
