FFF 3D Printer Slicer Feature Comparison

Slic3r

• Perimeter ordering outermost-first (or default: innermost-first)
• Perimeter Speeds can be changed independently of the Infill speeds
• Outermost Perimeter Speed can be adjusted
• Custom Infill Angle
• Print Infill before Perimeters (or default: Perimeters Before Infill)

Simplify3D

• Perimeter ordering outermost-first (or default: innermost-first)
• Outermost Perimeter Speed can be adjusted, but not perimeter speeds as a group.
• Custom Infill Angle per layer (using multiple processes)
• Injection of custom GCode at various events (layer change, tool change, etc.)
• Rudimentary Scripting, but documentation is lacking.

This should be a in matrix-like table.
