2020年5月28日 · 5. Laser Cutting. Similar to laser drilling, laser cutting relies on a focused laser beam to ablate material, straight cut, or cut patterns to very precise depths in the material or component. Ultrafast lasers are typically used for various types of metals and polymers because they cut clean edges and do not create heat-affected zones.

2018年9月5日 · After earning his degree, he set out to search for an area of research using the speedy femtosecond laser that he could call his own. “I realized that in biology, femtosecond lasers were considered a glorified cutting tool,” Vukelic says. “I felt that there had to be something more we could do with them.

2022年1月26日 · The researchers had been using infrared lasers in the lab for cutting acrylic and fiberboard for different projects and wondered what would happen if they used it on dough. The laser nicely browned the outside but didn’t cook the inside. The team then tried a blue laser, thinking that a laser on another wavelength might produce different results.

2024年7月23日 · In laser powder bed fusion (LPBF), the part geometry is divided into a series of 2D layers. A laser melts and fuses each layer to the build plate to construct the part. This process rapidly cools the part as each layer is melted, improving layer adhesion, surface finish, and overall strength of the print.

2020年9月28日 · Hey also discussed why the report makes clear that DOE should be the lead agency on this initiative. He points out that National Science Foundation (NSF) has identified AI as cutting across its priorities and Big Ideas. He explains DOE should be the lead agency because it focuses on date sets and powerful computing for science.

2020年2月28日 · Like every inventor, Hobson has a garage packed with tools. These range from laser cutters to 3D printers. Sometimes, they provide cosmetic packaging for his concoctions. Other times, like his metal printed 20-kilowatt heat saber, they are highly functional. It’s been quite a journey. From Winning Robotics Competitions to an Undrivable Car

2017年8月16日 · Laser machining applications include pressure vessel welding, orifice drilling, proximity sensors welding, leading-edge hole drilling, battery welding, and sensitive electronics glove box welding. “For the aerospace industry, laser welding capabilities play an integral role in everything from flight components to airport security procedures ...

2023年3月7日 · 1. Fiber laser machines. A fiber laser machine is essentially an engraver that uses a laser to mark metal surfaces such as anodized aluminum, zinc, and steel. Markings range from engraving serial numbers on parts to logos, QR codes, and barcodes.

laser sintering rapid prototyping process, which uses a laser to fuse powder instead of solidifying a plastic as SLA technology did. 1991→Stratasys produces the world’s first fused deposition modeling machine, which uses plastic and an extruder to deposit layers on a print bed. 1992→ Fused deposition modeling patent is issued to Stratasys.
