Heartysan: Personalised poster studio and store

The task

Our workshop sells personalised posters printed on paper and brushed metal, some with 3D-printed parts. Every order needed manual design work in several desktop programs. We wanted customers to design the poster themselves and the workshop to receive a file that goes straight to print.

What we built

  • Generators for sound waves, star maps, city maps, moon phases, lyrics spirals and mountain maps, all with millimetre-accurate geometry.
  • Poster editor with layers, snapping, grouping and per-material preview on paper, frames and four metal finishes.
  • 3D export: two-colour 3MF for Bambu Studio and GLB for rendering, plus a city-relief printer.
  • Store with accounts and checkout; listings are published from ShopFlow and mirror the Etsy offer.
