Laserteknik för nätformning (LENS)

Innehållsförteckning

Laserteknik för nätformning (LENS) is a cutting-edge manufacturing process that is revolutionizing the production of metal parts. This innovative technology utilizes a high-powered laser to fuse metal powders into precise, complex shapes directly from a digital model. It’s a game-changer in industries ranging from aerospace to medical devices. Let’s dive into the world of LENS and explore its intricacies.

Översikt över Laserteknik för nätformning (LENS)

LENS is a form of additive manufacturing (AM), also known as 3D printing, specifically designed for creating metal components. Unlike traditional manufacturing techniques, which often involve subtractive processes, LENS builds parts layer by layer. This method offers unparalleled design freedom, efficiency, and material utilization.

Key Features of LENS

  • Hög precision: Utilizes a laser to ensure precise shaping.
  • Materialets mångsidighet: Compatible with various metal powders.
  • Effektiv: Reduces material waste significantly.
  • Komplexa geometrier: Capable of producing intricate designs not feasible with traditional methods.

How LENS Works

LENS employs a high-powered laser to melt metal powders, which are fed through a nozzle and deposited onto a substrate. The laser fuses the powder into a solid, forming each layer according to a CAD model. This process is repeated until the part is fully formed.
