Material Overview

Glass Filled Nylon PA12 offers high tensile strength and rigidity, making it ideal for producing functional prototypes and end-use parts that need to endure mechanical stress and load-bearing requirements. In addition to its strength and stiffness, Glass Filled Nylon PA12 also exhibits excellent impact resistance. It can absorb and dissipate energy effectively, making it suitable for applications where parts may experience sudden shocks or collisions.

Mechanical Properties

Glass-filled nylon offers enhanced tensile strength and stiffness, making it highly resistant to warping and deformation under stress. This material also boasts improved wear resistance, ideal for components subjected to regular friction or movement. Additionally, the glass fibers within the nylon reduce shrinkage and warping during cooling, resulting in more dimensionally stable parts. However, it's important to note that while these glass fibers increase rigidity, they can also make the material less resilient to impacts compared to standard nylon.

Chemical Compatibility

Glass filled nylon demonstrates excellent thermal and chemical resistance. It is resistant to many chemicals, oils, and greases, allowing it to withstand exposure to various substances without deteriorating or losing its mechanical properties.

Thermal Properties

Glass-filled nylon created through Selective Laser Sintering (SLS) 3D printing exhibits enhanced thermal resistance compared to standard nylon. This property makes it particularly suitable for applications exposed to elevated temperatures, as the material maintains its integrity and performance under thermal stress, broadening its applicability in various industrial and mechanical settings where heat resistance is crucial.


Glass Filled Nylon PA12 is a versatile material that finds applications in multiple industries, including automotive, aerospace, consumer goods, and industrial manufacturing. Its combination of high tensile strength, stiffness, impact resistance, chemical resistance, and thermal stability make it a popular choice for producing functional, durable, and reliable 3D-printed parts.
