MODEL. REPAIR.
Print perfectly.
Essential is Clean Studio's browser-based 3D editor: sculpt, repair, resize and simplify your STL models before sending them to the slicer, for a clean print on the first try.

Everything you need before the slicer
From a raw file to a clean, print-ready model, without ever leaving your browser.
Sculpting brushes
Inflate, remove material, smooth, deform with the elastic brush, or add local detail: five brushes with adjustable radius, strength and hardness, with real-time preview.
Automatic repair
Closes open edges, fixes defective faces and mesh cavities, even without a full remesh, so you don't lose detail or bloat the file.
Remesh & simplify
Rebuild topology with surface subdivision or voxel remesh, or reduce the triangle count while keeping the original shape.
Flat base
Place a cutting plane and get a flat, closed base in one click, ready for the print bed.
Precise dimensions
Resize per axis in millimeters, with locked or free proportions, and revert to the original size anytime.
Undo/redo history
Every stroke and every transform can be undone: experiment freely without any risk of ruining your model.
From raw file to print
Upload
Drag your STL or OBJ into the browser, or pick it from your computer.
Model
Sculpt, repair, resize and simplify until the model is exactly right.
Export
Download the clean STL and send it straight to your favorite slicer.
What we're building next
Essential keeps evolving — here's what we're working on.
Split, for printing without an AMS
Soon you'll be able to split a model into separate parts meant to be printed individually — one per color or material — and glued together afterwards, no AMS system required.
