The use of fiber lasers for microwelding is increasing. They are particularly well-suited for microwelding medical and electronic components, such as hypodermic tube assemblies and disk-drive armatures.

When shopping for a micromilling machine, one of the first things you’ll need to consider is spindle speed—how fast is fast enough? The answer depends on a number of factors, including cutter diameter, workpiece material, required feed rate and the money in your bank account.

By using force in the same way as a cotton-candy-making machine, a small U.S. firm has become a force in the world of nanoscale fiber fabrication.

If there is a common theme echoed by manufacturers of microscale coils, forms and springs—all produced using microwire—it is that customers want more from less. That is, less in terms of size, not capability.

Nanopatterns on orthopedic implants may one day lengthen the service lives of those implants, slashing the number of replacement surgeries needed due to implant failures and improving the lives of millions of people with artificial joints.

The micromolding of liquid silicone rubber is increasing because of LSR’s ability to accommodate difficult-to-mold geometries, such as undercuts, tapers and angles.

Geologists say that the Colorado River once took a hard westward turn, then trickled its way across what is now northern Arizona to form the Grand Canyon. Abrasive waterjet pioneer Don Miller predicts there is another trickle coming, this one in the world of micromanufacturing.

Deburring parts smaller than 1?8" via mass finishing poses several challenges. Companies used to working exclusively with larger parts need to confront these challenges when deburring microparts.

Turn on the TV, pick up a consumer magazine or visit a popular Web news portal these days and you just might get an update on 3-D printing—the hottest topic in manufacturing.

Lasers offer a flexible, virtually trouble-free way to mark components for identification purposes. As a result, laser marking has gained ground on other parts-marking techniques.
