• Add print layers, top layer fill and imperfections all with a single node
• Highly customizable
• Special node for transparent filament - NEW: 3 types of infill 
• Can be used with any material and as an asset in Blender's asset browser
• Watch the video for a complete overview and how-to!

If you're into 3D printing, you'll want these shaders!

New in v3 for Blender 4 (Oct 2023):

• Set print direction per material
• More realistic 1st/top layer 
• More customization options
• New imperfections
• New 3D Printed Plastic node with preview feature
• New 3D Printed Transparent filament node now with 3 different types of infill, more customization options and perimeter preview mode
• Note for v1/v2 users: No more baking normals to mesh required in v3!

Demo: White plastic has different print direction

Transparent filament: 3 types of infill

Perimeter preview mode (fast preview, no displacement)

Tips:

• Mesh required (no texts or curves)
• Good topology helps a lot, remesh if necessary
• Apply all transforms
• Cycles: Add adaptive SubDiv modifier to the bottom of the modifier stack (best with quad-based topology!)
• EEVEE Next: High poly required, add SubDiv modifier to the bottom of the modifier stack
• Dimensions: Default settings of the nodes are for very big objects (e.g. default round cube), for small objects adjust the paramaters: Increase all the "scale" parameters, reduce the imperfections depth

Enjoy!
