What It Is

BumpMesh by CNC Kitchen is a browser-based texture/displacement tool for 3D printing and model processing. Users can import STL, OBJ, or 3MF files, add textures to the model surface, and then export them as STL or 3MF. Its core positioning is not as a full modeling application, but as a lightweight tool for quickly adding bumps, relief effects, or surface details to existing models.

Core Features and Compatibility

The tool supports a preset texture library as well as custom displacement map uploads, with controls for texture height, inverse displacement, symmetric displacement, UV scaling, offset, rotation, and more. It offers a fairly rich set of projection modes, including Triplanar, Box, cylindrical, spherical, and multiple planar projections, making it suitable for different shapes. Masking can include or exclude areas by angle, top/bottom surfaces, or brush selection. Advanced features include overhang protection, bottom flattening, mesh regularization, and baked textures. Import supports STL/OBJ/3MF, while export supports STL/3MF, fitting common 3D printing workflows.

Pricing, Licensing, and Privacy

BumpMesh is completely free and explicitly allows commercial use, such as processing STL files for clients or products. Attribution is encouraged but not required. Commercial licensing or embedding it into another business/website requires contacting the official team. All processing runs locally in the browser, and files are not uploaded. The website does not use cookies, analytics, or tracking technologies, though access logs may be handled by GitHub Pages. This is a clear advantage for users who care about keeping their models confidential.

Pros and Cons

The advantages are that it is free, requires no installation, is privacy-friendly, and provides fairly detailed controls specifically for 3D-printing texture workflows. The drawbacks are also clear: the official statement says the tool is provided as-is, with no guarantee that issues will be fixed and no support provided. Beta feature behavior may also change. High-resolution exports may additionally be limited by a safe triangle-count cap, so complex models should be checked carefully.

Who It’s For and Access from China

It is suitable for 3D printing hobbyists, product prototyping teams, model makers, and designers who need to quickly add surface textures to STL files. The text does not specify access conditions from mainland China. Since it is hosted on GitHub Pages, actual availability may depend on the network environment. Payment support only mentions PayPal, Ko-fi, and the official store, with no information on domestic Chinese payment methods. If access or workflow limitations become an issue, alternatives such as Blender, Meshmixer, or ZBrush may be worth considering.
