Making Needles with Lasers: technical breakdown, key moments and clinical context

Published on 8 May 2026 ('Making Needles with Lasers', 1:16 Short), this engineering feature shows how Neuralink fabricates its surgical insertion needles in-house using precision lasers to mill microscopic features—invisible to the naked eye—that grasp and release each flexible electrode thread without tearing it.

The needle grasps and inserts each electrode thread of our implant into the brain.

We've built the technology to produce these needles in-house, using lasers to mill features invisible to the naked eye.

What this video demonstrates—and what it does not establish

What this video demonstrates

  • Vertical integration of micron-scale surgical tooling inside Neuralink's manufacturing facility.

Scope limits & what it does not establish

  • Manufacturing component overview; surgical safety depends on the complete R1 + imaging + sterile cartridge workflow.

How this fits into Neuralink's broader clinical and hardware roadmap

This video sits inside the N1 hardware & R1 surgical robotics research track on StonkBuilder's independent Neuralink hub. All Neuralink hardware (the N1 implant and R1 surgical robot) and clinical programs (PRIME NCT06429735, CONVOY, and VOICE NCT07224256) remain investigational and have not received FDA commercial marketing authorization. Read our full companion guide at N1 hardware & R1 surgical robotics for cohort context.
