01 VORONOI NEW

From solid to organic lattice

Meshmixer's voronoi effect, in your browser: cells and thickness in real millimetres, paintable solid zones and always-printable output. Perfect for lamps, planters and lightweight parts.

Generate voronoi → See live example 📊 6 lattices generated
Solid vase before voronoi → The same vase turned into a printable voronoi lattice

−82% material · watertight, print-ready
02 REDUCE

Mesh too heavy?

Cut your STL/OBJ triangle count while keeping the shape: far lighter files, easy to share and edit. In your browser, nothing uploaded.

Reduce mesh → See live example 📊 2 meshes reduced
Dense mesh with 71,680 triangles → The same part reduced to 7,168 triangles

03 CUT STL NEW

Doesn't fit your printer? Cut it

Pick your printer and we split the model into pieces that truly fit its bed — using each model's real build volume from our database. With alignment dowel holes for straight glue-ups and always-watertight pieces.

Cut my STL → See live example 📊 7 models cut
30 cm model that doesn't fit the bed → The same model cut into four pieces that do fit

04 TEXT & QR NEW

A name, a keychain

Type some text and take it home as a printable keychain, plate or sign; or turn your WiFi or a link into a physical QR. Eight fonts, relief or engraving, and a two-part download for two-colour prints. No limits, no sign-up.

05 LITHOPHANES NEW

Your photo, turned into light

Upload a photo and turn it into a printable lithophane: it comes alive when backlit in a lamp, a frame or a keychain. Size and thickness in millimetres, flat or curved, and your photo is never uploaded.

08 MATERIALS

Will it print what you need?

A traffic light per model and material: green it just works, amber with care, red don't bother. And always the why, from its specs.

DOES IT PRINT…
Creality Ender 3 V3 SE
open · 260°C
PLA / PETG
Yes. With a nozzle up to 260 °C and a bed up to 100 °C it comfortably meets PETG's needs.
✓
ABS / ASA
With caveats. It reaches 260 °C, but it's open-frame: ABS can warp and ventilation is advised. Doable in a draft-free spot or by adding an enclosure.
≈
Nylon (PA)
With caveats. It reaches 260 °C but is open-frame; Nylon warps in drafts and absorbs moisture. Enclosure + drying almost mandatory. For carbon-fibre variants, use a hardened-steel nozzle.
≈
PC
Not recommended. With 260 °C nozzle and/or no enclosure, PC won't print reliably.
