# Using Sensor Fusion to Analyze Laser Processing in Additive Manufacturing

Sensor: “A device that detects or measures a physical property and records, indicates, or otherwise responds to it.” A sensor is a device that detects a physical quantity and responds by transmitting a signal.

# Bringing New Vision to Laser Material Processing Systems

The use of modern laser technology has become standard in industrial manufacturing thanks to its speed, accuracy and effectiveness. Lasers are used to engrave parts, electronic printed circuit boards or chip cards. They perforate packaging; structure semiconductor wafers; drill, cut and weld plastics or metals; and create highly complex structures via 3D printing.

# 3D Imaging Reveals Sub-surface Battery Flaws

Ed Barnard

Traditional imaging technologies have been used to investigate overall solar efficiency, but many of the methods only offer surface views. A new – and “exciting” – ultra-fast laser technique developed at the Department of Energy's Lawrence Berkeley National Laboratory provides a deeper look and maps a solar cell in three dimensions.

# Autonomous Vehicles Open Up New Roads for LIDAR Growth

Laser range-finding, or LIDAR, is a way of measuring distance, directly analogous to radar except using radiation in the near infrared range of the electromagnetic spectrum rather than the radio waves used in radar. LIDAR techniques are used for a variety of final applications including terrain-mapping for geology, urban planning and archaeology; distance measurement for surveying, golf, hunting, military applications, and docking of large ships; and speed measurement for traffic monitoring and speed limit enforcement.

High-power (multi-kW) fiber lasers are revolutionizing industrial materials processing markets by offering an unmatched combination of performance, reliability, and cost advantages. For example, in sheet metal cutting (the largest application, with more than $1B/year of laser sales), fiber lasers provide the highest cutting speed (especially for thin sheets, the dominant application), scalability to thick sheets (>1”), and the ability to process a wide range of metals with a single tool. Along with low power consumption and high reliability, these capabilities result in the lowest cost per part. Fiber lasers have thus been the fastest-growing segment of the laser market for the past decade.

You already know getting there will require the latest video imaging technology from an incredibly small, sub-millimeter, package; in other words, a distal chip-on-tip (COT) video camera. The COT needs to integrate into an elegantly designed, flexible device and allow video imaging into anatomy that was previously inaccessible, or image into the tiny dark crevices of our mechanized world. The technology has to be inexpensive, yet video performance needs to be competitive with larger sensor video products with which the market is already familiar. (Figure 1). So, where do you start to identify appropriate video technologies and vendors?

Analysts from the San Francisco, CA-based business consulting firm Grand View Research spoke with P&IT about current camera technology's most exciting capabilities, applications, and leaders.

Unlike subtractive manufacturing methods such as machining, the growing range of AM technologies creates components directly from a computer model, adding material only where needed. Wohlers Associates, a leading independent consulting firm focused on these technologies, is forecasting that the value of the worldwide AM market will grow to more than$10.8 billion by 2021, up from just \$2.2 billion in 2012. That rapid escalation, however, isn't the result of hobbyists buying desktop 3D printers that cost a few hundred dollars.
