In high-volume manufacturing, inspection often struggles to keep pace with production. That challenge becomes even greater when the material itself is naturally variable and the defects aren’t always easy to define consistently. In one high-volume manufacturing environment producing about 20,000…
The modern metric system—known as the International System of Units, or SI—is a model of consistency and logic. But in some cases, the logic seems to break down.
In this article, we’ll explore some of these quirks and why they (mostly) make sense at the end of the day (or…
What would you do if a 240-kg iron rock older than the Earth landed outside your house?
While you ponder the many exciting possibilities, Replicad engineer Jaap Termeer has created a superrealistic digital twin of the meteorite. Such a scanning scenario is uncommon, even for 3D…
In various industries (or in your shop), there are numerous parts that make use of very small holes. A dozen examples could be listed, but the most common include aerosol cans, needles for delivering fluids and medicines, fuel-injection nozzles, and simple fixed restrictors used to control…
On paper, material testing looks like one of the most controlled and reliable parts of a construction project. Samples are collected, standardized procedures are followed, and results are documented with precision. Everything points toward certainty.
And yet, failures still happen…
Aircraft are routinely exposed to damage from bird strikes, lightning strikes, hailstorms, collisions with ground support equipment, or debris on the runway.
As fleets grow and skilled technicians become harder to find, airlines and maintenance, repair, and overhaul facilities (…
