A focused add-on for one job: making a mesh look 3D printed. The Geometry Nodes approach and the included PLA shader keep the setup contained, though you'll want a clean, manifold, sensibly scaled mesh before you start.
3Dprintify is a Blender add-on from globglob3d that turns the geometry of any object into a version that looks 3D printed. It works by creating slices of geometry, the same way a 3D printer would, and ships with a PLA shader whose base color you can change in the shader editor. It's aimed at 3D print sellers who want to create renders of their products instead of relying on photography.
The workflow runs through Geometry Nodes. You triangulate your mesh with the Triangulate Modifier, append or add the provided node group, then press play on the timeline to watch the object build layer by layer. Once it's fully built, you apply the modifier. Controls cover layer height, defaulting to 0.28mm, and precision, which sets how closely the curves follow the base object and how many polygons result.
Meshes should be manifold, watertight, and at a real-world 3D printable scale. Very large objects or very fine layer heights can slow processing or crash Blender depending on hardware, and dense meshes may need the Decimate Modifier first. It's compatible with Blender 4.3, 4.2, 4.1, 4.0, and 3.6 under a GPL license.
3Dprintify is best for 3D print sellers who want rendered images of their products rather than relying on photography.
3Dprintify is completely free to download and use.
3Dprintify supports Blender 4.3, 4.2, 4.1, 4.0, and 3.6. It's an add-on distributed under the GPL license and is listed as Blender Extension compatible. The tool relies on Geometry Nodes, so you add its node group to an object by appending it or using the provided file. Before that, triangulate your mesh with the Triangulate Modifier and apply any other modifiers first, which speeds up baking because Blender won't recompute them each frame.
3Dprintify works through a Geometry Nodes group. First triangulate your mesh with the Triangulate Modifier, then append the node group or use the provided file and add it to the object. Press play on the timeline and let the modifier build the object slice by slice, the same way a 3D printer would. Once it's fully built, apply the modifier. Layer Height controls the height of each layer, with a default of 0.28mm, and Precision controls how closely the curves follow the base object and how many polygons result.
3Dprintify expects a mesh that is manifold and watertight, with face normals facing outward; voxel remeshing can help if you run into problems. The node group is built for real-world sizes, so keep your object at a 3D printable scale. Objects larger than 50x50x50cm or layer heights below 0.12mm may be too slow to process or can crash Blender depending on your hardware. Very dense meshes can cause lag, so reduce the polycount with the Decimate Modifier before using it if needed.
3Dprintify is listed as free in this catalog. Licensing and pricing can change over time, so check the developer's page for the current terms before downloading. The add-on is distributed under the GPL license and is marked as Blender Extension compatible. If you run into problems, globglob3d offers support via Discord, and a demo video is available. The tool turns a mesh into a version that looks 3D printed and works through a Geometry Nodes group you add to your object.
