Create, repair and print in 3D.

From idea to object. And your printer, ready to go.

Create the model, prepare it, print it, buy whatever you are missing and, if your printer fails, fix it with the AI.

Create in 3D with AI

Describe the part, upload a photo or start from a guided project: the agent proposes the model and you check it before printing.

Each project keeps its ideas and versions, like a conversation: come back whenever you like and pick up where you left off.

• AI studio
• Text to 3D
• Image to 3D
• Guided projects

Prepare your model

Paint it with real filaments, split it into parts with joints, close simple holes in the mesh, change the format and work out what it costs. All in the browser, without spending credits.

We print your design

Coming soon: upload your STL, 3MF or GLB and we will ship it to you printed. We are not taking orders yet.

Fix your printer with AI

For any 3D printer, filament or resin: usi3d's AI tells you what to check and how to fix it, step by step and with its sources.

• Tell it what is wrong: choose your printer from the catalogue, or “Other”, describe the fault and, if you like, add up to four photos.
• The AI ranks the causes: it tells you what to check first and why, with the sources of each guide, and flags what usi3d has not verified yet.
• You fix it, step by step: follow the checks, tick them off as you go and say at the end whether it is fixed.
• And every case improves it: what worked for you and what the AI does not know yet are noted so usi3d can extend its guides.

• Text to 3D: Describe your part, add reference images if you like and get its 3D model to review in your browser. Your first generation is free; downloading the model requires the Pro plan.
• Image to 3D: Upload an image of your part and get its 3D model: Detail with one image or Studio with several real photos of the object. Your first generation is free; downloading the model requires the Pro plan.
• Guided projects: Pick a specific part (your pet as a figurine, a desk organiser, a keychain, a planter or a terrain), customise its details and check the cost before generating its 3D model.
• Colors and filament: Edit the colors of your STL or GLB, check materials and export your project as GLB or 3MF.
• Split into parts: Upload your STL, 3MF or GLB, pick your printer and split it into parts that fit its bed, with numbered dowels that fit together.
• Repair an STL model: Find open edges, duplicate faces and orientation issues in your STL and close simple planar holes, in your browser. Check the result in your slicer.
• Convert 3D files: Convert your STL, OBJ and GLB models in the browser into the format you need.
