PrintReady – watertight STL from any image or text

Turn a photo or a line of text into a watertight, print-ready STL in one click

Problem

3D printing hobbyists hit a wall: they have an image or text they want printed, but the generated mesh isn't watertight and slicers throw errors. Manual repair is tedious. Someone built an image-and-text-to-STL tool and specifically advertised "watertight, print-ready" — a sign this barrier is real and worth solving separately.

Solution

A minimal web tool: upload a PNG/JPG or type text, choose thickness, size, and base style, and the backend handles rasterization, extrusion, sealing, and manifold checking to output an STL that opens cleanly in major slicers. A simple repair mode also fixes existing broken STLs.

Users

3D printing hobbyists, makers, teachers, small print shops

MVP

Image to relief/badge STL; text to sign/nameplate STL; automatic watertight check and repair; size and thickness controls; one-click download

Revenue

Free low-res export, per-use $2 or $8/mo for high-res/commercial export; slicer software affiliate deals

Why now

Consumer 3D printers are everywhere, but non-modelers are still blocked by watertightness and slicer errors; WASM makes browser-side processing nearly free
