Although everyone knows that plastic injection molding can produce mass volumes of parts with precision and low cost, not every manufacturer gets the process right, which could defeat its purpose and ...

One of the greatest advantages of designing plastic parts is the vast number of assembly options a designer can apply to his or her design. The most common among these options is the use of screws.

Over the last five years, two main advances have helped additive manufacturing (AM) evolve from a prototyping technology to a viable production method. Over the last five years, two main advances have ...

Editor's Note: An updated version of this information can be found here. What exactly is computer-numerical-controlled (CNC) machining? It’s a means to make parts by removing material via high-speed, ...

OpenSCAD has a lot of fans around these parts — if you’re unaware, it’s essentially a code-based way of designing 3D models. Instead of drawing them up in a CAD program, one writes a script that ...

When it comes to creating miniature parts, innovative cutting and machining processes continually make more intricate features and precise geometries possible. Although advanced machining can create ...

In Part 1, I discussed the background behind lock-in amplifiers. Here, I’ll cover analog and digital lock-in amplifiers, software-defined radio, de-embedding, and the hardware and software ...
