In 2022, the EDM market is growing at a rapid, predictable rate of 6.9% CAGR (based on a market size of US$5.3 billion in the year 2020 and projected growth through 2027).  What is the Electrical […]

The Product Requirements Document (PRD aka Product Requirement Document) is a familiar term to most engineers. Typically, we get the PRD from a product manager; it tells us what to build but not how to build it. But let’s face it, it’s probably better that way. Engineers hate being told how to implement an idea — that’s the fun […]

Say you’re 3D printing a robot, and you’re designing a sweet gearing system to make your robot move smoothly. You can choose to 3D print or CNC machine involute gears for simple and reliable incorporation in your robot design. What to do about the fact that most CAD programs don’t have a “create involute gears” button? Welp, you’ll […]

Known for a having a hardworking and meticulous nature, Abraham Lincoln once said, “Give me six hours to chop down a tree, and I will spend the first four sharpening the axe.” While you probably aren’t reading this article for tree-felling advice, what Abe was getting at is that careful planning is important for any […]

Titanium (Ti) is a shiny metal with a high corrosion resistance and high strength. Titanium is impressively lightweight and biocompatible. Titanium is a transition metal with atomic number 22, period 4 and group 4 on the periodic table. It has a hexagonal crystal structure and two electrons in its fourth orbital, with an electron configuration […]

When you think of agility, something that comes to mind may be the agility competitions for dogs that are broadcast for interested parties to cheer their favorite dog on. You might recall the obstacles the dogs must navigate (typically 14-20), in order to secure a qualifying score or win. Dog agility competitions are serious, with […]

One of the most important considerations when designing parts for 3D printing in 2022 is the 3D printing wall thickness, sometimes referred to as the wall thickness. While 3D printing makes prototyping easier than ever—not only in terms of cost and speed, but also in regards to DFM (design for manufacturing), you can’t disregard DFM […]

CNC (Computer Numerical Control) machining has been around for decades. CNC machining is more popular than ever with today’s technological advancements in machining, along with a vast array of superior metal alloys such as superalloys. There is a wide array of CNC machining providers from in-house machining services to outsourced manufacturers to the innovative on-demand […]

The first step in designing a part is to determine what material it should be made out of. If you decide the part should be plastic, and it should be CNC machined, the selection does not simply stop there. There is a plethora of machinable plastic to choose from for plastic machining in 2022, each […]

Understanding the differences amongst the mechanical properties of strength vs. stiffness vs. hardness is foundational in mechanical engineering, yet these properties can often be confused. These properties are related, but there are very important differences between them:  Stiffness is an indicator of the tendency for an element to return to its original form after being […]

Software and hardware engineers alike have heard some form of this advice: “Build lots of prototypes; iterate as fast as you can.” For those of us in the hardware industry, these prototypes can cost a lot of time and money. So, while we should strive to iterate quickly, we must also get as much information […]

Like most SOLIDWORKS software users, you likely collaborate with other people on part designs or assembly projects. Collaboration is typically a good thing. After all, two heads are better than one, right? However, not everyone uses SOLIDWORKS, so the people you collaborate with likely end up sending you files with extensions like IGES, QIF, JT, […]

You’ve envisioned it, you’ve modeled it, and you’ve printed it. As it turns out, however, your newly printed prototype may need a bit more TLC before it appears, or functions as intended. 3D printed part finishing often involves a cleaning step to improve appearances or remove unwanted support material.  The purpose of this article is […]

Products that are subject to a torsional load often require analysis like the analysis used for bending stiffness. The main differences are the specific material property to be used (Shear Modulus or Modulus of Rigidity) and the polar moment of inertia (which is very similar to the area moment of inertia used in bending). Torsion […]

In a world of ever-increasing electronics, our lives are continuously impacted by devices that incorporate some sort of heat-generating circuitry. When it comes to electronics that dissipate power in the form of heat during normal operation, it is often necessary to manage this heat, to ensure the components don’t exceed their maximum allowable temperatures. One […]

Depending on the intended use case for your 3D printed part, structural integrity can be a crucial ingredient. It could be a matter of ensuring that your product doesn’t collapse when used or even a matter of ensuring user safety. The world in 2022 seeing a vastly accelerated need for 3D printed parts in mult-disciplinary […]

Fillets are one of those mysterious design features for which there seem to be no clearly defined rules. Either a part is entirely devoid of fillets, and most or all edges are well-defined, or the part’s designer decided to take the opposite route, and every single edge and corner is rounded with some size of […]

Today’s product complexity, along with increasing downward pressure on overall pricing, has led to an inevitable increase in the geometric complexity of mechanical components. The increased geometric complexity allows components to be utilized in an advanced way, typically performing multiple functions. This multi-functional utilization has led to complex load transfers, resulting in new stress concentrations. […]

Developing a new product and bringing it to market is a massive undertaking, but it’s also what drives the advancement of any industry. The Harvard Business Review says that “ideally, a successful new product can set industry standards—standards that become another company’s barrier to entry—or open up crucial new markets.”  Not every product can pace […]

Copper is a truly versatile metal. Copper has a naturally beautiful, shiny finish that makes it desirable for artwork, cookware, kitchen backsplashes, countertops, and even jewelry.
