4.3.7 Layers settings
Press on the “Layers” icon on the bottom of the window to move to the next step of the process.
This screen enables many of the options and settings for adjusting properties of 3D models. It also allows the user to add multiple 3D
models to be printed in one printing session.
1. Model: Select which model is currently
being modified.
2. Profile: Select one of the saved layer profiles
or choose to create a new one.
3. Perimeter: Activate or deactivate the
perimeter.
4. Infill: Activate or deactivate the infill.
5. Pattern: Tap to choose infill pattern.
6. Density: Indicate how dense the model
should be.
7. First layer height: Specify the thickness of
the first layer in percentage of layer height.
Corning advises to set the first layer height
at 60% to 100% of layer height.
8. Layer height: Specify the thickness of each
layer in mm. Corning advises to set the layer
height at 80% to 100% of nozzle diameter.
First layer height can vary.
9. Number of layers: Select the number of
layers.
Modify options to define the 3D model’s layers and how the Corning® Matribot® Bioprinter should bioprint the selected model. Use the
predefined settings or create custom settings. Descriptions of the infill pattern options are included below.
• Grid pattern: Suitable infill for tissue constructs with isotropic mechanical characteristics. This infill pattern is consistent across
adjacent layers, resulting in solid walls between the pores and good compressive strength. This pattern is most applicable for tissues
such as bone and cartilage. It can also generate constructs with porosity to allow diffusion of nutrients or filling with other bioinks or
materials.
• Honeycomb pattern: Suitable for constructs with isotropic mechanical characteristics. This infill pattern is consistent across adjacent
layers, resulting in solid walls between the neighboring pores with good compressive strength. This pattern is most applicable for
tissues such as bone and cartilage. This pattern can also generate constructs that contain porosity to allow diffusion of nutrients or
filling with other bioinks or materials.
• Rectilinear pattern: Suitable infill for tissue constructs with isotropic mechanical characteristics. This pattern is most applicable for
tissues such as skin, fascia, and cartilage. This infill pattern changes the fill angle by 90 degrees based on the layer.
• Linear pattern: Similar to the rectilinear pattern, except shifted by 45 degrees instead of 90 degrees from layer to layer. This pattern is
suitable for fibers and striated tissues. It can also generate constructs that contain porosity to allow diffusion of nutrients or filling with
other bioinks or materials.
• Concentric pattern: Suitable for irregular shapes and circular objects. The infill mimics the shape of the outer walls, creating concentric
ripples. It is ideal for high infills and complex geometries, and it ensures that the structure is filled in. NOTE: There is minimal crossing
of filaments, which might be detrimental for the structural integrity of the construct.
• Gyroid pattern: Consists of wave-like patterns which are suitable to use in applications that require elasticity. The pattern is similar in
structure and orientation to the rectilinear pattern. This is most applicable for tissues such as skin, ligament, muscle, tendon, and others
where elasticity is important.
