Moldea is a free web tool that turns a few dimensions into a flat, printable template for slab-built ceramics — no sign-up, no cost, no app to install. Enter the size you want the finished piece to be, and Moldea works out the exact flat pattern, already enlarged to compensate for clay shrinkage, ready to print at true 1:1 scale and cut from a slab.

For slab building — building ceramic forms by cutting and joining flat clay sheets instead of throwing on a wheel — you need an accurate flat development of the finished shape, correctly enlarged for shrinkage. Moldea does that geometry for you instead of eyeballing it or scaling a printed circle by hand.
Moldea is a free web tool that generates flat, printable templates for slab-built ceramic pieces — mugs, bowls, vases, teapots, and more — sized to the exact dimensions you want for the finished piece.
No. Moldea works the moment you open the page — no account, no sign-up, no cost. It's a static site with no backend, so it keeps working as long as the page is online.
Every template includes an adjustable shrinkage percentage (12% by default) that enlarges the flat pattern so the fired piece comes out at exactly the dimensions you asked for, after drying and firing shrinkage.
Lathe-profile vessels (mug, bowl/flowerpot, two-section vase, teapot, mate cup, vase, casserole, small lidded pot), plus a rectangular tray, a snack-dish set, and cuttable slab letters/numbers.
Yes — that's exactly what it's for. Instead of throwing on a wheel, you cut the flat template out of a slab of clay, then curve and join the walls along the marked cut and fold lines.
It prints at true 1:1 scale and always includes a 100×100mm calibration square — measure it after printing to confirm your printer or browser didn't silently rescale the page.
