3D strength isn’t a technical measure of strength, but it refers to when a pattern offers a good mix of tensile, compression, and shear strength. Shear strength follows another dimension compared to tensile and compression strength, which focuses on the Z-axis plane strength.ģD Strength: Lastly, we have what I like to call “3D strength”. Shear strength: Shear strength is across the X/Y plane, and it represents how resistant a model is to being ripped apart from its side. This type of strength is important for infill patterns because it is essentially the impact strength of a model. This is perfect for printing hooks!Ĭompression strength: Compression strength is the exact opposite of tensile strength and represents the strength of a part as it’s compressed from top to bottom. The higher the tensile strength of an infill pattern, the more resistant to being pulled apart your model is. Tensile strength: Tensile strength is the strength along the Z-axis, but I like to think about it as “the strength of being pulled”. I’ve gone over a few different types of strengths below: It’s important to briefly go over a few types of strength because knowing how a specific infill pattern is strong will help you determine if you want that pattern for your print. Some patterns provide more strength across the X/Y plane, while others provide more strength along a part’s vertical (Z plane). Just like with a building or a bridge, different infill patterns offer different strength benefits.

This arrangement style (structure) is known as the infill pattern.Īs we mentioned, there are many different infill patterns that you can choose from, and each has its own benefits and downsides. This density isn’t just randomly put into the inside of a 3D model, though, and it’s specifically arranged. Infill density is a percentage value that controls the internal solidity (fullness) of a 3D model. The easiest way to explain infill pattern is to think about the term “infill” in two parts: infill density and infill pattern. Infill pattern is the internal shape and structure of a 3D model.
