New EDM technology rapidly removes printed parts from build plates, reducing cost and lead time.

3D printing offers a wealth of opportunities to iterate rapid prototypes for testing and more.

Jairus of All recreated the Hidden Blade from the popular video game series Assassin’s Creed with help from quick-turn machining at Protolabs.

3D printing is making major inroads into customising medical implants for individuals. It allows implant manufacturers and sometimes even hospitals to create complex geometries and patient specific solutions that saves the surgeon time and improves a patient’s outcome.

When it comes to getting a fabricated sheet metal part that is consistent with a complex set of technical requirements, ensuring that a supplier has all the necessary information to generate an accurate quote is the first (and most important) hurdle to cross.

There’s one of only a few 3D printing processes that is possible at both a desktop- and industrial-level. It’s fused deposition modeling (FDM), although you’ll sometimes see it referred to as fused filament fabrication (FFF). It’s a great printing process to create prototype parts to test fit and form. Because it prints using thermoplastic material, it also delivers parts that are functional when in a high-heat environment, or when exposed to chemicals or mechanical stress.

There’s one fundamental thing you need to know about threading and assembling inserts into 3D-printed parts: What you can and can’t manufacture depends on the material properties of both the part and the insert. A second thing to keep in mind: It pays to design for standard taps and inserts whenever possible.

A newly machined metal part can end up with edges that are sharper than desired for the end user unless the design smooths or breaks those sharp edges. To create an edge break, the design should incorporate sloped or beveled edges and corners known as chamfers—or rounded ones called fillets.

When you hear the term “over-engineering,” you probably think about all of those overly complicated products we’ve all encountered that seem too complex relative to their intended use. The confusing shower faucet controls. The washer or dryer with a dizzying array of counter-intuitive buttons and settings. Your new car’s baffling audio setup. Well, you get the idea.

It is not a question of if but rather when will the next black swan event hit the globalized supply chain. And it is critical that companies learn from the last couple of years and develop an agile supply chain network that delivers value, reduces risk, and is not just driven by cost.

1018 and 4140 steel are two popular material choices. Here are factors to consider when choosing between the two.
