Podia3D turns a clinical prescription into a printable orthotic insole, in the browser. Set arch, heel cup, postings and per-zone firmness — no CAD. Export standard STL/3MF for any FDM printer. Closed insole systems bundle software, printer and material at 3–5x the price. Podia3D is just the software: design from clinical parameters in your browser, export standard STL/3MF for any FDM printer and TPU, and get a draft EU MDR declaration per insole.
