QTREX converts 3D-printed insulation into graphene-like carbon to shield quantum processors

Across all 20 laser-processing conditions tested, the process produced conductive carbon, with Raman spectroscopy confirming a graphene-like structure in the resulting material. Researchers found that laser power and scan speed could be used to control electrical resistance and conversion depth, establishing a manufacturing window that balances electrical performance against the structural integrity of the printed substrate.

QTREX Quantum Ltd. (Nasdaq: QTEX), a developer of Additively Manufactured Electronics (AME) for quantum computing infrastructure, has demonstrated a patent-pending process that directly converts sections of 3D-printed dielectric insulation into electrically conductive, graphene-like carbon, using localized laser processing rather than adding separate conductive materials. The research was conducted with Northeastern University using QTREX’s AME platform and its DF INSU300 dielectric material.Across all 20 laser-processing conditions tested, the process produced conductive carbon, with Raman spectroscopy confirming a graphene-like structure in the resulting material.
