Create Images on the surface of your 3D prints - each layer alternates through a fixed CMYK (or other) pattern, only varying the amount of overhang around the edge of your print. This creates a smooth surface, printing your image texture on the model with no additional seams.

Zoomed-out G-code preview:

OBJ Image Texture Loading

Load OBJ files with image textures or vertex colors - slice in full image resolution, no need to subdivide your model or bake vertex colors first

Fast multicolor printing

When printing image textures with this fork, only a single color is used per layer (not dependent on texture color). You can print many different models at once without increasing the number of tool changes.

Print images on your prime towers

Turn your prime towers into ornaments (requires no extra tool changes, and typically <1g additional filament)

Image Projection

2D Gradient Generation

Create 2D Gradients on your object by changing a texture mapping zone's pattern to "2D Gradient"

Paintable regions

Texture mapping and gradients integrate with OrcaSlicer color painting, so if you wanted you could have texture mapping only on one part of the model, and a solid filament color or gradient somewhere else.

Some Background

Open-source slicing has always been built on a tradition of collaboration and attribution. Slic3r, created by Alessandro Ranellucci and the RepRap community, laid the foundation. PrusaSlicer by Prusa Research built on Slic3r and acknowledged that heritage. Bambu Studio in turn forked from PrusaSlicer, and SuperSlicer by @supermerill extended PrusaSlicer with community-driven enhancements. Each project carried the work of its predecessors forward, crediting those who came before.

OrcaSlicer began in that same spirit, drawing from BambuStudio, PrusaSlicer, and ideas inspired by CuraSlicer and SuperSlicer. But it has since grown far beyond its origins. Through relentless innovation — introducing advanced calibration tools, precise wall and seam control, tree supports, adaptive slicing, and hundreds of other features — OrcaSlicer has become the most widely used and actively developed open-source slicer in the 3D printing community. Many of its innovations have been adopted by other slicers, making it a driving force for the entire industry.

OrcaSlicer-ImageMap is a fork of OrcaSlicer made by sentientstardust, to add image printing support using overhang and alternating CMYK (or other color) layers.

The OrcaSlicer logo was designed by community member Justin Levine (@freejstnalxndr).
