Material Selection

Xtellar has materials to fit a variety of applications. However, knowing which materials to select can sometimes be a challenging task. We developed some easy to use references below to help guide you.


Material properties are based on 3D printed test specimens printed in X-Y direction following a standardized methodology to ensure consistency between materials. This page is meant to provide a brief overview of our materials, each one of our product data sheets includes a much deeper analysis of each product and its properties.  Data sheets can downloaded by visiting the product listing page.

3D Material Comparisons

Tensile Strength.png

Tensile Strength

Tensile strength is the maximum stress that a material can bear before breaking when it is allowed to be stretched or pulled.

Flexural Modulus

The flexural strength of a material is defined as the maximum bending stress that can be applied to that material before it yields.



 Density is the measurement of how tightly a material is packed together. Higher density typically results in heavier parts, lower density typically results in lighter weight parts.
