Torlon® (PAI): A High-Performance Plastic With Advanced Material Properties

Torlon®, the brand name for polyamide-imide (PAI), is an ultra-high-performance thermoplastic known for its exceptional mechanical strength, thermal stability, and chemical resistance.  It has the highest strength and thermal resistance of any melt-processable plastic, with continuous use temperatures up to 260°C. Torlon is often used in extreme conditions, such as aerospace, oil & gas, and […]

Thermoplastics vs. Thermoset Plastics: Material Properties Overview

Thermoplastics and thermoset plastics are classes of polymers used in injection molding, CNC machining, 3D printing, and urethane casting. Like elastomers, another class of polymer, thermoplastics and thermosets both consist of long, repeating chains of molecules. Under a microscope, the structure of a thermoplastic resembles a railroad track while a thermoset material looks like a […]

How to Design for Stiffness Using Material Properties

Improving part stiffness is critical for load bearing applications, and can be accomplished through both design geometry and material properties. In this article, we’ll employ many of the same formulas we discussed in our previous article about leveraging geometric structures to improve stiffness. However, here we’ll focus on material selection, altering the properties of materials […]

Material Properties Faceoff: RepRap vs Commercial 3D Printers

We get a lot of questions about the performance of different 3D printed materials and technologies, specifically as it relates to parts printed on hobbyist vs commercial-grade machines. There are plenty of off-the-cuff ways of making such evaluations, but empirical data is certainly better. So we were pretty excited when we came across a recent academic […]

POM(Acetal/Delrin®) Plastic: Properties, Advantages, and Material Comparisons

Imagine designing a complex assembly with rotating parts that come into contact with each other. You have dialed in your dimensions and tolerances, ordered fasteners, and assembled your prototype parts. But as you rotate the components, they bind against each other, or even make grinding or squeaking noises. In this case, you may need a […]

Micro Injection Molding: Materials, Design, Tolerances & Applications

Micro molding is more than just the manufacturing of small plastic parts; it represents a highly specialized apex of injection molding, where precision is measured in microns and tolerances are tighter than a human hair. It is the enabling technology behind modern medicine’s life-saving catheters, connectors found in your smartphone, and fluid circuits that enable […]
