![]() With a cross-over pattern on each layer, the grid infill can add more strength than rectilinear and concentric patterns. This could be an advantage if your object needs a higher infill density. However, it is less complex and uses less material. It also provides only mid-strength support compared to the triangles. Surprisingly, this infill pattern prints slower when used to fill in a rectangle. Achieving a smooth object surface with this infill pattern is difficult.Faster print time compared to other honeycomb patterns.Parts printed with triangular infill are not likely to deform.Parts that have to support heavier loads.Increase strength when choosing a low-infill density.To add support to parts with thin walls.Often the default infill used for plastic, composite, and metal prints that need high stability, the triangle pattern is one of the most versatile. To print out this infill, the printer arm only travels in straight lines across the part. It improves structural strength when forces are applied perpendicular to the face of the printed object, forming hexagon shapes much faster than the actual hexagon infill.Īnother advantage is the printing speed. See also How To Connect Ender 3 To PC: A Complete Setup Guide May require additional vertical support when filling long, vertical cylinders.Ĭonsidered the strongest pattern, the triangle infill makes sense for parts with thin walls and rectangular components.One of the slowest to print at high densities.Adds exceptional strength and load distribution at high density.Maintains object flexibility at lower density.Round, spherical, or cylindrical objects.Rigid parts that need a good distribution of load. ![]() This makes it suitable for a wide range of projects, such as: One of the most peculiar infills, the concentric pattern can be one of the most flexible or one of the strongest, depending on the infill density. Ideal to use for round or spherical prints, the concentric infill pattern also works well with rectangular or odd shape objects. Nonetheless, it remains relatively flexible and is not ideal for objects that need a high mechanical strength. You can use it for:įound in all types of slicing software, the concentric infill is a type of 2D pattern designed to add vertical stability. The Lightning infill is a perfect choice for decorative objects that don’t need a lot of mechanical stability. The rest of the model interior remains hollow. It can also save up to 90% of material used by other infill patterns, since it is designed to only provide internal support to those parts of the model that need it. ![]() However, Lightning may or may not be an option on other slicers.ĭifferent from any other infill patterns released before it, the Lightning infill was developed to decrease printing time by at least 25%. In 2022, Prusa adopted the pattern, including it in the PrusaSlicer 2.5 and beyond. The Lightning infill is one of the newest patterns introduced by Ulimaker with its Cura 4.12 version, back in 2021. The type of 3D printer and slicer software you’re using can also impact speed rates and alter this ranking. Patterns ranked lower on this list may be fastest than infill patterns ranked higher for different shapes and infill rates. *Disclaimer: Infill patterns are ranked based on the total printing time calculated for a cube object at an infill rate of 18%. ![]() While we listed the infill patterns from the fastest to the slowest, keep in mind that the infill density, material, and software you’re using can influence the actual print time. If you’re on the run, selecting the fastest pattern may save the day. Infills can enhance structural stability and resistance, but they could increase the printing time by a few hours. This newly released infill is best for objects that don’t need great mechanical stability. In Cura and PrusaSlicer, the fastest infill pattern is the Lightning. This pattern consists of only one line, with the lack of directional changes saving the printer time. The fastest 3D printing infill pattern is the concentric. When creating solid core objects, selecting the fastest infill pattern could make the difference between running late or finishing your project on time. One of the most important things in 3D printing is speed. ![]()
