Fixing

Do you need to fix?

Many generations slice fine straight from Exporting. Try the raw download first. You only need to fix if:

• Your slicer reports "non-manifold mesh", "open edges", or refuses to slice.
• The print has obvious holes / missing surfaces in the preview.
• You need a watertight, single-shell mesh (most resin printers need this for hollowing).
• The piece came out hollow with no way for liquid to escape: a shoe, a hat, a glove. Sealing that in the Studio is the difference between a print and a resin trap.

The Studio (in-browser)

The Studio is the full editor, free for everyone, and it runs in your browser, with nothing to install. Beyond repair it will cut, sculpt, paint, decimate, combine pieces and seal openings. Its Fix tools are the ones that matter here:

• Close holes. Finds every opening and caps each one to the shape of its own rim.
• Fix topology. Drops the degenerate and duplicate faces slicers choke on.
• Flatten base. Settles the model onto the print bed with a flat foot.
• Check solid. Tells you whether the mesh is watertight, and what is wrong if it isn't. It changes nothing.

All of it is free, including exporting your own edited work.

Prepare for print (automatic)

Prepare for print is the one-button option for when you don't want to open an editor at all. Pick it from the result page, choose how much detail to keep, and press the button. It runs on your own computer, so nothing waits in a queue, and you get a file to save when it finishes.

• Tidies the mesh. Merges duplicated points, drops anything nothing refers to, and combines the pieces into one object.
• Reduces the polygons. Your choice of none at all, a quarter, half, or three quarters. Fewer polygons means a smaller file that opens faster in a slicer.
• Rebuilds the shading so the surface reads smoothly instead of showing facets and seams.
• Stands it on the print bed. The model sits on zero instead of half-sunk through the bed, so your slicer opens it in the right place.
• Tells you what it found. The polygon count before and after, whether the surface is fully closed, and how long it took.

Cost: nothing. It is free for everyone, with or without a membership: no credits, no separate purchase. Because it runs on your computer, a big model takes longer on an old machine than on a new one.

3DP Ocean Fixer (desktop)

Coming soon. The Fixer is our native desktop app (Mac + Windows). It does everything the browser tools do plus the heavy operations that don't fit a browser:

• Remesh. Rebuild the topology at a target density. Great for fixing terrible AI-generated triangulation.
• Hollow + drain holes for resin printing: pick wall thickness, place drain holes, save the resin.
• Decimate. Reduce triangle count for FDM where the detail isn't visible at print scale.
• Split. Cut a model into multiple parts at custom planes (for prints larger than the build volume).
• Batch process. Drag a folder of models, apply a recipe, get fixed files out.

The Fixer signs in with the same email and password as the website: one account, two surfaces. It works offline once licensed, so the long fixing operations don't depend on our servers.
