Augmented reality (AR) and virtual reality (VR) are cutting-edge tools that are becoming increasingly important to engineers for applications ranging from product design to assembly line layout.

Automotive engineers are intrigued by the numerous benefits of metal additive manufacturing for applications ranging from seat brackets to under-the-hood components.

Plastic injection molding, metal casting and metal stamping are age-old processes that form the backbone of manufacturing. Traditionally, there's no better way to mass-produce plastic or metal parts.

Aircraft wings have been assembled the same way for decades. But, engineers at the Massachusetts Institute of Technology (MIT) and NASA have developed a flexible aerostructure that is produced from hundreds of tiny, identical pieces using composite lattice-based cellular materials.

Strong and lightweight, carbon-fiber reinforced plastic (CFRP) offers numerous benefits to automotive and aerospace manufacturers. Many engineers are intrigued by potential applications for the material, yet remain frustrated by joining challenges.

Hackers are one of the biggest threats to digital factories and Industry 4.0 initiatives. If conveyors, fastening tools, robots and other equipment are not secure, state-of-the-art production technology can be rendered useless.

Factories of the future will feature advanced technology, such as additive manufacturing, artificial intelligence, augmented reality, data analytics and digital twins. While many manufacturers are still ramping up their Industry 4.0 initiatives, several assembly plants are already at the forefront. They are embracing the Fourth Industrial Revolution and reaping the benefits.

Lights-out automation has been a dream of engineers for more than 200 years. The goal is to push a button and let machines work unattended.

Traditionally, it's not unusual to see people wear goggles and other types of safety glasses in factories. But, a new class of wearable devices is becoming increasingly popular on assembly lines.
