Stratasys Direct introduces Nylon PA12 GF for SAF technology
Stratasys Direct Manufacturing has expanded its material portfolio by introducing Nylon PA12 GF (Glass Filled), a material crafted for Selective Absorption Fusion (SAF) technology. This advanced composite material delivers improved stiffness, heat resistance, and dimensional accuracy, making it an ideal choice for industrial applications.
Nylon PA12 GF is distinct due to its 40% glass bead-filled composition, which provides exceptional strength, durability, and precision. The incorporation of glass beads enhances stiffness and heat resistance, setting it apart from standard materials. This innovative composite is designed for versatility and reliability, excelling in situations where toughness and dimensional stability are paramount.
The stiffness of Nylon PA12 GF, with a a high tensile and flexural modulus, enables 3D printed components to maintain their structural integrity and resist deformation under pressure. This makes it a perfect solution for load-bearing applications where strength and rigidity are essential.
With a heat deflection temperature exceeding 100°C at 264 psi, Nylon PA12 GF raises the bar for thermal performance in SAF materials. This capability makes it suitable for demanding applications like automotive components and industrial machinery. The glass bead reinforcement enhances its ability to perform reliably in high-temperature environments, further solidifying its role in challenging industrial use cases.
In terms of dimensional precision, Nylon PA12 GF from Stratasys achieves tolerances as tight as 0.010” or 0.002 inch-per-inch. While traditional Nylon 12 materials often experience 3-4% shrinkage during printing, Nylon PA12 GF ensures consistent and precise outcomes, making it ideal for intricate designs and critical prototypes.
The versatility of Nylon PA12 GF positions it as a go-to material for both prototyping and end-use production across diverse industries, including automotive, aerospace, and consumer goods. It excels in creating durable and accurate components like housings that endure significant real-world stresses.
A notable example of its durability is a case where a facility replaced a broken hinge with a Nylon PA12 GF part, which performed reliably for over six months under load. Its application in automotive parts, such as coolant hose brackets, highlights its ability to withstand heat while maintaining dimensional stability. Additionally, its compatibility with freeform geometries allows for innovative designs without the need for added support.
