Description

Zhiguo Lei and seven co-authors build a strong, light aluminum composite with a friction-based printer, in this 2025 paper. The material mixes carbon nanotubes into a 2A12 aluminum alloy, a blend prized for aircraft parts. Melting-based printing can wreck nanotubes, so the team used additive friction stir deposition, which kneads softened metal into place without melting.

They printed a block 22 millimeters tall with a clean, layered, onion-like structure and no flaws. Grains stayed fine and even, and strength beat the base alloy in both directions, at no less than 450 megapascals with at least 15 percent stretch. Corrosion current fell to four percent of the base material's rate, thanks to evenly spread particles that block micro-galvanic attack. The study supports friction printing for flight-grade parts.
