Key Features

Pepr3D is an intuitive, free, and open-source 3D painting tool for coloring models intended for colorful 3D printing.

• Primarily, we support multi-material 3D FDM printers such as Prusa printers with their multi-material upgrades.

• Import existing single-color 3D models in various formats (.obj, .stl, and more), e.g., from Thingiverse.

• Color the model surface with intuitive tools such as triangle painter or paint bucket that follow the triangle topology.

• Paint details and texts using brush and text editor tools. They are not limited by the original topology!

• For faster painting, segment the model automatically or semi-automatically.

• Export the final result into individual .stl files using our easy-to-use export assistant.

• The exported files can be printed directly via the official Prusa Slicer (GitHub) using a multi-material Prusa 3D printer.
