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 […]

High-Pressure Die Casting: Process Overview, Applications, and Material Considerations​

How do you mold metal inside of metal? High-pressure die casting (HPDC) can do this very efficiently and is widely used for the production of complex, high-precision metal components in high volume. The process is known for its rapid cycle times and ability to produce intricate shapes with excellent dimensional accuracy.  This manufacturing process is […]

Rapid Injection Molding Guide: Process, Materials, and Benefits

If you need to design plastic parts and quickly get them to market, then (surprise!) rapid injection molding might be your answer. Rapid injection molding is an excellent option for production-grade parts without waiting months for traditional hardened-steel tooling, especially if you require multiple mold iterations before you settle on a final design.     Rapid injection […]

Sheet Metal Prototyping: Processes, Materials, Applications, and Benefits

Sheet metal prototyping is a proven method for evaluating a part’s form, fit, and function before full-scale production. Modern advancements in fabrication tools and digital workflows have made the process faster, more precise, and closely aligned with production intent—allowing teams to iterate quickly and reduce time to market without compromising quality. Prototype fabrication uses standard […]
