Overview

MeshRefinery is a free, browser-based tool that diagnoses and repairs broken 3D meshes — open edges, holes, non-manifold geometry, floating debris — so files pass slicer checks, all via WebAssembly with no upload or signup required.

It also converts between STL, OBJ, and GLB/glTF. Paid deep repair (20 credits) rebuilds a fully watertight surface while preserving original colors, and AI image-to-3D (30 credits, via Tripo API) turns a single photo into a textured GLB model.

Built for 3D printing, game assets, and AR/VR pipelines.

FAQ 12

What is MeshRefinery?
MeshRefinery is an online tool designed to assist users in repairing broken 3D models with formats such as STL, OBJ, and GLB. It's capable of making 3D models acceptable for slicing software and also allows photo transformation into 3D models.
How does MeshRefinery repair broken 3D models?
MeshRefinery repairs broken 3D models by diagnosing issues such as invisible holes and debris within the browser. The tool identifies these flaws and rebuilds the meshes at a click, making them watertight. The repair process involves rebuilding the model's geometry to make it watertight, along with more in-depth repairs to restore surface details and colors.
What types of 3D model formats does MeshRefinery support?
MeshRefinery supports multiple 3D model formats, including STL, OBJ, and GLB. It is also capable of format conversion between these formats.
How does MeshRefinery ensure user's privacy?
To ensure privacy, MeshRefinery performs all the processing and repairs locally via WebAssembly within the user's browser. There's no need for file uploads, and the user's model never touches a server.
Can MeshRefinery repair any type of 3D model, regardless of its source?
Yes, MeshRefinery's compatibility extends to 3D models sourced from any generator or scan, demonstrating its versatility and effectiveness within the 3D modelling sphere.
What issues can MeshRefinery identify in a 3D model?
MeshRefinery can identify a range of issues in a 3D model. This includes invisible holes, non-manifold edges, open edges, floating fragments, loose shells, debris, and other defects that might affect the model's integrity and its slicer compatibility.
What is the process of repairing a 3D model using MeshRefinery?
To repair a 3D model using MeshRefinery, users simply drop their file into the tool. Format is instantly parsed in the browser without any uploads. A diagnostic report identifies any defects or issues before proceeding. After reviewing, users can chose to repair or convert the file with a single click then download the resulting repaired file directly to their device.
Can MeshRefinery transform a photo into a 3D model?
Yes, aside from repairing 3D models, MeshRefinery also provides the functionality to transform photos into 3D models.
What does the 'making watertight' process in MeshRefinery entail?
The 'making watertight' process in MeshRefinery involves removing defects such as open edges, holes, and floating debris from a 3D model, rebuilding the geometry to ensure there are no leaks or gaps. This operation produces a watertight file, which is especially important for the acceptance of the model by slicing software.
Does MeshRefinery support format conversion? What formats can be converted?
Yes, MeshRefinery supports format conversion between STL, OBJ, and GLB. This extends the tool's versatility, making it more useful for users who work with different 3D modelling formats.
Is there any type of preview or diagnosis report provided before repairing a 3D model in MeshRefinery?
Yes, MeshRefinery offers a diagnosis report function. Before any repair costs are incurred, users can view this report to understand the issues with their model. This ensures clarity, convenience, and a degree of control over the repair process.
What makes MeshRefinery effective in the 3D modelling sphere?
MeshRefinery's effectiveness in the 3D modelling sphere springs from its ability to diagnose and repair a wide range of issues found commonly in 3D models. It repairs models from any source, removes unseen holes and debris, rebuilds watertight meshes, and performs surface restoration. Its ability to transform photos into 3D models, along with compatibility with multiple formats, enhances its utility.
