Model type

A relief raises the bright parts of the picture above a base plate: terrain, embossed logos, signs. A lithophane is a thin plate that is thicker where the picture is dark, so the photo appears when light shines through it. Print it in white filament.

Model size (longest side)

Height

Relief: how far the brightest parts rise above the base plate. Lithophane: the thickest point of the plate (the thinnest is 0.8 mm). Auto uses 5 mm for a relief and 3 mm for a lithophane.

Mesh detail

More detail keeps finer features of the picture, but the file gets bigger and slower to slice.

Swaps high and low, for example to raise a dark logo on a white background.

Understanding PNG and 3MF file formats

PNG (Portable Network Graphics) is a popular raster image format known for its lossless compression and support for transparency. It is widely used for web graphics, digital artwork, and images requiring high quality and clear backgrounds.

3MF (3D Manufacturing Format) is a modern file format designed for 3D printing. It stores 3D model data, including geometry, color, and material information, in a compact and extensible XML-based structure. 3MF is supported by many 3D printers and modeling applications, offering advantages over older formats like STL.

How to convert PNG to 3MF

Converting a PNG image to a 3MF 3D model is not a direct process, as PNG is a 2D image format and 3MF is a 3D model format. The conversion typically involves two main steps:

  1. Convert the PNG image to a 3D model (such as STL or OBJ) using image-to-3D software. This is often done by creating a height map or extruding the image based on its brightness or transparency.
  2. Export or convert the 3D model to 3MF using a 3D modeling application that supports 3MF export.

Recommended software for PNG to 3MF conversion

  • Microsoft 3D Builder (Windows):
    • Open 3D Builder and import your PNG image using Insert → Add → Load Image.
    • Use the Convert to 3D tool to extrude the image into a 3D object.
    • Export the model as 3MF via Menu → Save As → 3MF.
  • Ultimaker Cura (Windows, macOS, Linux):
    • Import the PNG as a height map using Extensions → Post Processing → Modify G-code or via plugins.
    • Export the 3D model as 3MF using File → Save Project.
  • Online converters:
    • Web-based tools like Selva3D or Embossify can convert PNG to STL, which can then be imported into software like Microsoft 3D Builder for 3MF export.

Tips for best results

  • Use high-contrast PNG images for clearer 3D extrusion.
  • Edit the PNG to remove unnecessary backgrounds or noise before conversion.
  • Adjust extrusion depth and smoothing settings in your chosen software for optimal 3D model quality.

Summary

While there is no one-click solution to convert PNG directly to 3MF, using tools like Microsoft 3D Builder or Ultimaker Cura makes the process straightforward. Start by converting your PNG to a 3D model, then export it as a 3MF file for 3D printing or further editing.
