3D printing infill settings have become a topic of curiosity among 3D printer owners. Many are interested in printing objects with different materials and structures, but not everyone has full understanding of what the different infill options mean. In this quick article, we’ll take a peek at each type of infill and how it’s best for particular subjects.

What is an infill?

An infill is a type of material used to add strength and stability to 3D Printing objects. Depending on the type of infill, it can be printed using a variety of print settings. This guide will discuss the different types of infill and their respective print settings.

The three main types of infill are: solid, liquid, and powder fillers. Solid infill are typically used when strength is more important than weight savings, while liquid and powder fillers are best suited for reducing weight or improving surface finish.

When selecting an infill, you’ll want to consider the object’s intended use. For example, if you’re Montreal printing an object that will be placed in direct contact with skin, you’ll want to select a solid infill. Conversely, if your object will only be used as a ornament or display piece, a powder filler may be more appropriate.

Infills and their Different Types

3D printing infill settings is one of the most important settings when printing with 3D printers. It’s responsible for how much material is used to create the final product, and determines how strong the finished product will be.

There are a few types of infill you can use in your printing process:

-Solid Infill: This type uses a consistent amount of fillers throughout the entire print. This is ideal for prints that need to be strong, like objects that will be used as part of a physical model. 

-Gradual Infill: With this setting, the printer will use different amounts of fillers throughout the print. This helps to create more realistic details, but it can lead to prints that are less strong. 

-Perimeter Infill: This type uses even more fillers near the edges of the object, which creates a stronger finish and prevents warping. 

Each type of infill has its own benefits and drawbacks, so it’s important to choose the right one for your printing project.

How to Understand Infill Density

The infill density is one of the most important variables when printing with 3D printers. It determines how much material is used to print each layer and affects the final product’s strength and durability. The following are three infill densities and their respective benefits:

Very Low Infill Density: Used for models that require a very low level of detail or where there is limited space. This type of printing requires less material, which results in a lighter product. However, Very Low Infill Densities can cause problems with adhesion and can lead to print failures.

Low Infill Density: Recommended for models that require moderate detail but no structural support. This type of printing uses more material than Very Low Infill Densities, but it allows for more accurate prints without causing any problems with adhesion or print failure.

High Infill Density: Recommended for models that require high detail and structural support. This type of printing uses the most material, which results in a stronger product but also increased time and complexity during printing.

Infill Density Examples

Infill density is one of the most important settings when printing with 3D printers. When printing with infill, the goal is to create a solid object from a bunch of small pieces that are glued together. The higher the infill density, the more solid objects you will end up with. However, high infill densities can also cause problems.

Here are some examples of how high infill densities can lead to problems:

-Overhangs can become too steep and difficult to print

-Parts can start to pull away from one another

-Bumps and ridges can form in your object

In order to avoid these problems, it is important to understand what setting should be used for your particular 3D printer and situation. There is no one right answer for all cases, but following some general guidelines will help you get started: 

-For low-resolution printers: Use between 30 and 50% infill density. This will produce prints that are strong and smooth without any overhangs or bumps. 

-For medium resolution printers: Use between 60 and 80% infill density. This will produce prints that are strong and smooth, but may have a few overhangs or bumps. 

-For high resolution printers: Use between 90 and 100% infill density. This will produce prints that are very strong and smooth, but may have lots of overhangs or bumps.


If you’re new to 3D printing, or if you’re just looking to improve the quality of your prints, you’ll want to pay attention to the infill settings that are used when printing with a standard printer. Knowing the right infill settings can make a huge difference in the final product, and it’s something that you’ll want to experiment with until you find an optimal setting for your specific 3D printing setup. In this article, we’ve outlined what each of the different infill settings is meant for and provided some tips on how to get started using them.
