Infill provides a 3D print with the necessary internal supports in order to print the top layers without the plastic sagging into the empty parts of the print. With the ability to change the strength, buoyancy, weight and amount of material used, the infill pattern can be an important factor to consider when printing.
Grid
A strong 2D infill, the grid infill pattern is great for standard prints that will only see a little bit of use. As a medium strength infill pattern, it offers a reasonable amount of rigidity in all directions, but heavy use will wear them down pretty quickly. It is also a faster infill pattern, as it is a less complex pattern.
Lines 1 / rectilinear
Considered a quick 2D infill, this infill is great for models and figurines that will not see functional use and will probably sit on a shelf or desk. As a fast infill pattern, this infill pattern could still potentially used for prototypes as long as they’re not being used for strength. The infill can also be good for flexible filaments.
Triangles
Considered a strong 2D infill, this infill pattern is great for parts that will only see a little bit of use. With triangles incorporated into the infill pattern, the pattern has an inherent advantage when a lateral load is applied perpendicular to the object’s face and for parts with thin rectangular components. Despite this, the pattern takes longer to print.
Tri - Hexagon / stars
Considered a strong 2D infill, this infill pattern is great for prints that will only see a little bit of use. The hexagons in this pattern act as a more efficient shape because it has shorter lines connecting each side, leading to fewer issues with bowing from poor print cooling. It also is a strong infill pattern relative to the material use. Despite this, the pattern takes longer to print.
Cubic
Our default infill pattern for most functional parts when high strength is required in multiple directions and when models will see heavy use or need to withstand a moderate amount of force. As a strong 3D infill that involves a 3D pattern of stacked and tilted cubes, it is great to make objects strong in all directions.
Cubic Subdivision
Considered a strong 3D infill and a variation of the Cubic infill that uses less material, this infill pattern is great for functional parts when high strength is required in multiple directions and when models will see heavy use or need to withstand a moderate amount of force.
Octet
Also known as Tetrahedral, this strong 3D infill incorporates stacked pyrimad shapes and is great for functional parts that will see heavy use or need to withstand a moderate amount of force in multiple directions.
Quarter Cubic
Simlar to Octet, this infill pattern also has pyramids, but hald of the pyramids are shifted with respect to the other half. This strong 3D infill is great for functional parts that will see heavy use or need to withstand a moderate amount of force in multiple directions.
Concentric
A great 3D infill that excels for printing with flexible filaments, this infill pattern creates shapes that mimic the shapes of the outer walls
Zig Zag
A fast, low strength infill pattern mostly used for models and figurines and other parts that won’t see any functional use and will probably sit on a shelf or desk. It could also potentially be used for prototypes as long as they’re not being used for strength.
Cross
A great 3D infill that excels for printing with flexible filaments, this infill pattern produces grids of crosses, where the spaces between crosses and grids allow for bending and twisting.
Cross 3D
A great 3D infill that excels for printing with flexible filaments, this infill pattern is similar to Cross, but as the print grows, the lines move in inclines. This results in objects with slightly more rigidity, while still being flexible.
Gyroid
Great for parts that will be stressed in multiple ways, this infill pattern is great for printing functional parts and models that will see heavy use and when high strength is required in multiple directions. This infill provides a great amount of strength for a reduced amount of material.
Lines 2
Considered a quick 2D infill, this infill is also great for models and figurines that will not see functional use and will probably sit on a shelf or desk. As a fast infill pattern, this infill pattern could still potentially used for prototypes as long as they’re not being used for strength. The infill can also be good for flexible filaments.
Honeycomb
A very efficient infill that can save time, material and energy, while also offering high strength. This infill provides a greater amount of strength in all directions than a rectangular pattern, with little increase in print time. This infill is a great infill for the strength vs. the amount of material used.
3D Honeycomb
Similar to the Honeycomb infill, this infill also saves time, material and energy, while still offering high strength. This infill also provides a greater amount of strength in all directions than a rectangular pattern, with little increase in print time. This infill is also great for the strength vs. the amount of material used.
Hilbert Curve
A great looking pattern that can take slightly longer due to the crazy movements the printer has to make on each layer.
Archimedean Chords
A great looking pattern than can take slightly longer due to the crazy movements the printer has to make on each layer.
Octagram Spiral
A great looking pattern than can take slightly longer due to the crazy movements the printer has to make on each layer.
