Materials & Software Correspondent
Theo Marsh is a materials engineer who got pulled into 3D printing chasing better filament and never left. He covers the things that decide whether a print succeeds long before the nozzle heats up: filaments and resins, material properties and sourcing, slicer software and firmware, and the print-process settings that turn a spool into a finished part. He follows the open-source toolchain closely — Klipper, Marlin, and the major slicers — and translates release notes and material datasheets into advice makers can use.
