Free online 3D printing tools, right in your browser

GigaPrint is a 3D printing workbench that runs in your web browser. Split an STL that is bigger than your printer into bed-sized blocks, make a lithophane from a photo, press a model into a relief plaque, or fix a broken mesh. There's nothing to install, and your files are processed on your own device and never uploaded.

Split STL for 3D printing

Scale any STL, OBJ or 3MF to the size you want and cut it into blocks that fit your printer bed. Joints: pegs, dowel pins, snap clips, dovetail slides, magnet pockets or flat faces for glue. Optional hollowing with vent holes, 50+ printer bed presets, and 3MF build plates.

Lithophane maker

Turn a photo into a flat panel, a curved display or a lamp cylinder that shows the picture when light shines through. Rectangle, rounded, oval, heart and arch outlines.

Relief plaques

Press a 3D model into a raised plaque, like a coin, medallion or carved sign, viewed from any side, with a frame.

Drawing to 3D

Trace a drawing or logo (PNG or JPG) into a cookie cutter, stamp, keychain, badge or solid extrusion.

Laser and CNC sheets

Slice a model into stacked layers or an interlocking waffle, laid out on sheets and saved as SVG files with kerf compensation.

Low-poly and wireframe

Restyle a model as a faceted low-poly sculpture or a printable 3D wireframe.

STL repair

Check an STL, OBJ or 3MF for holes, flipped faces, gaps and loose bits, fix them in one click, and reduce the triangle count of huge scans.

Questions

Is GigaPrint free?

Yes. The free plan needs no account and covers splits up to 4 pieces with pegs or flat joints, lithophanes and reliefs up to 100 mm, repairs up to 200k triangles, one laser sheet, and unlimited cookie cutters and tags. Pro is coming soon at $7.99/month, $39/year or $79 lifetime, and will unlock every tool at full size.

Are my files uploaded?

No. GigaPrint runs entirely in your browser. Models and photos are processed on your own device and never leave it.

Do I need to install anything?

No. Open gigaprint.app in a current desktop browser (Chrome, Edge, Firefox or Safari). It needs JavaScript and WebGL.

How do I split an STL that is bigger than my 3D printer?

Open the Giant print tool, load your STL, set the finished size and your printer bed size, and GigaPrint cuts the model into blocks that fit, with joints so the pieces line up. Download the parts as STL files or 3MF build plates.

Which file formats are supported?

It opens STL, OBJ and 3MF models and PNG or JPG images, and saves STL, 3MF build plates and SVG cut sheets.

Is GigaPrint an alternative to LuBan?

For splitting large models into printable pieces, lithophanes, reliefs, laser layers and wireframes, yes: GigaPrint covers similar jobs in the browser, with no download. LuBan is a desktop app for Windows and macOS with more generative methods.

Can I sell what I print?

Pro covers hobby projects and selling the prints you make. Commercial ($69/year or $149 lifetime) is for print shops, farms and studios and adds a commercial license and priority support.
