Want to Learn more about buying your own 3D printer? If you print your parts through us, we will help you decide on the best settings based on the requirements of your application. The thickness of the outer shell and the how the part is oriented when printing are also important factors for the strength of the print. A higher infill percentage will result in a longer print time, especially on models with a large interior volume.Īlso, keep in mind that infill is not the only setting that can impact the strength of a printed part. Print speed is another factor to consider when choosing an infill percentage for a 3D print. ![]() Models with more interior volume will see a significant impact to the cost from changes in infill percentage, whereas thinner parts may see no impact. The price difference between higher and lower infill settings can vary greatly depending on the geometry of the model. ![]() ![]() However, increasing infill percentage beyond 60% has diminishing returns on strength. If there are large flat surfaces on the top of the print, some infill is needed to support those surfaces.Ģ0-40%: Light-use parts: For functional parts which will undergo some force, a moderate level of infill provides nearly the same strength as a solid part at a reduced cost.Ĥ0-100% Heavy-use parts: If your parts must withstand significant forces, or strength is the most important factor above cost, a higher infill percentage is the best choice. Use these recommendations to choose the best infill percentage based on the requirements of your project:Ġ-20%: Non-functional parts: For pieces that are not functional or do not need to withstand force, such as a display model or presentation prototypes, 10-20% infill is sufficient. In some cases, no infill is a viable option if there are no large flat surfaces on the top of the print.
