# What percent infill is strongest?

## What percent infill is strongest?

The obvious answer here is that 100% infill will be the strongest infill percentage, but there is more to it. We have to balance out printing time and material with part strength. The average infill density that 3D printer users apply is 20%, also being the default in many slicer programs.

## What is a good infill?

Infill patterns such as grid, triangles, or tri-hexagon are most appropriate. Note, however, that these patterns may increase print time by up to 25% compared to lines. Triangles: A 2D mesh made of triangles, this pattern has an inherent advantage in strength when a load is applied perpendicular to the object’s face.

## Is Gyroid infill strong?

Many 3D printing enthusiasts have carried out their own studies and testing, all pointing towards a similar result: Gyroid infill is stronger and has faster printing times than other infill patterns.

## How to use infill percentage and pattern successfully?

The secret on how to use infill percentage and pattern successfully is to find the sweet spot where sufficient strength is achieved for a 3D object’s designed purpose, with both material cost and print time being kept within acceptable range.

## How to choose the right infill percentage for the job?

Print Time and Filament Usage Infill Percentage Print Weight (Grams) Print Time (Minutes) Estimated Cost 60% 13.36 45 \$0.31 70% 14.94 51 \$0.35 80% 16.59 55 \$0.39 90% 18.08 61 \$0.42

## How to choose infill percentage on a 3D printer?

How to Choose Infill Percentage. 3D Printer infill patterns, or the internal structure of an object, are a necessary part of printing some 3D objects, especially those that require a measure of strength or sturdiness. That being said, infill is also something of a pain.

## How does infill affect the strength of an object?

In general, the strength of an FDM object is directly tied to the infill percentage used during printing. For example, a part utilising 50% infill is approximately 25% stronger than a part that utilises 25% infill. However, the amount of strength gained by increasing infill percentage does not increase linearly.
