Clear Visualization of Laser Additive Manufacturing with Powder Bed

Ғылым және технология

LAM, or Laser Additive Manufacturing, is a form of metal 3D printing that, much like in normal 3D printers, uses a source file as a blueprint to produce an object. LAM is used in different applications such as prosthetics, implants, and bio-compatible materials. In LAM, a laser mounted on a movable processing head moves over a building platform while feeding metal powder or wire which is then melted by a laser, thus adding layers on the printed object. LAM is different from cladding in that it prints in three dimensions.
In this footage our #CAVILUX Laser Illumination was used to image a LAM process. By being able to see through the bright thermal heat of the LAM process, the individual powder particles are clearly seen as they form the surface on the platform.

    This is probably a dumb idea but have you ever tried interleaving lit and unlit frames with a video like this? It might be interesting to blend the two with some kind of variable transparency so you can see where the heat is without losing the information that the illuminated setup provides. (exposure would probably be impossible unless the camera allowed some kind of signaling as well) This video brought it to mind because when you watch DMLS vids you can always see a small shower of sparks around where the laser is hitting the media bed. It made me wonder any of those pieces that are flying away in this video are incandescent.

    Very good question @jcims. You can achieve a similar effect by just increasing the camera exposure time. This allows for more thermal radiation to reach the sensor and you can make more of the plasma or bright particles visible. It depends a lot on the research purpose how much process light should be visible.
