Convert Images for 3D Printing

1. Vectorization: Your image (JPG, PNG, SVG) is converted to vector paths.
2. Extrusion: Each path is extruded upward along the Z-axis to create depth.
3. Mesh Generation: The extruded paths are converted to a triangle mesh (STL, 3MF, or OBJ).
4. Export: The 3D model is ready to slice and print.

Logos and Badges: Convert your company logo into a 3D sign or badge. Perfect for desk decorations, keychains, and promotional items.

Cookie Cutters: Extrude simple shapes into cookie cutter outlines. Print in food-safe PLA or PETG.

Signage: Turn text and icons into 3D signs for walls, shelves, and displays.

STL: The most common 3D printing format. Supported by all slicers and printers.

3MF: Modern format that supports colors, textures, and metadata. Preferred by Bambu Lab, Prusa, and other modern printers.

OBJ: Text-based format that supports colors and materials. Compatible with Blender, MeshLab, and CAD software.

File Formats Explained Convert PNG to STL Convert SVG to 3MF

A 3D printer needs a watertight surface mesh, not a picture. Converting artwork to STL, 3MF or OBJ means extruding every closed 2D region upward into a solid with a top, a bottom and vertical walls. The extrusion depth you choose is the model's thickness, and the slicer handles everything above and below that.

The part that determines whether the print succeeds is closure. A region that is not fully closed produces a surface with a hole, and the slicer cannot decide where solid ends and air begins. It will usually print anyway, with a missing wall or a stray fragment. Checking for closed contours before conversion is the single highest-value step.

STL is the universal format and every slicer reads it, but it stores only geometry — no units, no color, no material. 3MF is the modern replacement: it is also an XML package, so it can carry units, colors and multiple objects, and both PrusaSlicer and Bambu Studio read it natively. OBJ suits further modeling work in Blender or another mesh editor because it preserves structure better than STL when you need to edit rather than print.

If you plan to hand the file to someone else, 3MF is the best default. If you need maximum compatibility with older software, STL is the one that always opens.

An extruded region thinner than two nozzle widths will print as a single fragile wall or fail entirely. For a 0.4 mm nozzle, keep the model at least 1 mm thick. Layer height then controls the vertical resolution of any angled edge: 0.2 mm is the usual balance, and dropping to 0.12 mm makes a shallow ramp noticeably smoother at the cost of print time.

Models come out of conversion in design units, which rarely match millimeters. Most slicers let you scale on import, but confirming the unit before printing prevents a thumbnail-sized ornament or a phone-sized monstrosity. A flat base improves adhesion — if the design is a thin outline, adding a plinth in the slicer gives the print something to grip.
