CORE Panels — polished-steel sauna heater finish design

I model the geometry. AI renders the rest.

The brief: a new finish for the CORE heater. I used AI renders to test materials early and to sell the direction inside the team before anything was built.

I model only what AI can't define — lines, proportions and geometry, in SolidWorks — and prompt the rest: material, finish, light and background.

The finish was placed into a real sauna photo, so the team judged it where it will live, not on a white background. The render shortened the loop from idea to decision; the prototype tests what a render can't: heat, texture, durability.

    Prompt

    Material, finish, light and background.

  3. 03

    Context

    Checked in a real sauna before deciding.

  4. 04

    Prototype

    Real prototypes now in production testing.

AI visualised many looks fast. The brief, the assessment and the final design were mine.
