There are many terrific infill sample models out there, but we wanted something that met the specific needs of our shop and students. We're guessing others can benefit. So, here it is!

Classification of the styles

We've never been satisfied with the arbitrary way infill styles are presented in PrusaSlicer, nor have we found a sample board that clarifies the clutter. We've created a systematic way to present them here:

• 1st row: Top/Bottom Infills
• 2nd row: Centered Infills (Lighting, Concentric, Spiral, Chords)
• 3rd row: Orthogonal Vertical Infills (Zig Zag, Rectilinear, etc.)
• 4th row: Non-Ortho Vertical Infills (Line, Triangles, etc.)
• 5th row: Omni-directional Infills (Gyroid, Cubic, etc.)

It may appear strange to include the random Lightning style with other centered infills, but look carefully and you'll notice it logically organizes itself around the center as it cantilevers up the interior! Others may be baffling: the Zig Zag and Rectilinear are virtually identical, as are the Support Cubic and Adaptive Cubic. It's just the nature of the beast in this context.

By creating this system, we're bringing a little order to the seemingly random sets of options found in the slicer. This will hopefully make the task of choosing the right pattern for your job less of a guessing game!

Other features

• Infills featured in the newest edition of PrusaSlicer.
• Examples of top and bottom infills, which are often not included in models like this.
• Hexagonal blocks are removable from the base for inspection.
• Deep blocks to illustrate how 3D infills like gyroid or 3D honeycomb work.
• Scalable: at 75%, it can fit on the MK4 (as seen in the 3MF file), and it's also designed to scale up well to create a larger board on the XL. It's also designed to scale down non-uniformly in the Z direction, making it a less volumetric display suitable for a wall.
• All infills are represented at the default 15% in the 3MF file.

Other printing notes

• We did not include Monotonic or Monotonic lines since they are the defaults (OK, fine, it would have messed up our pattern, but that's our logic and we're stickin' with it). They ARE, however, indirectly present in the base, if not the samples.
• If using the STL file, you need to set up the infill in the slicer. Use our 3MF file as a guide for individually assigning the appropriate tops and bottoms, perimeters (where necessary), and various infills.
