How Polyjet 3D printing works. Polyjet 3D printing is the process of building up layers of photopolymers, by jetting droplets of UV curable liquid onto a bed, and curing it with a UV light layer by layer.
The process starts with a CAD file, saved to the required printer file type.
From hear the printer file is uploaded into the printer software, where the software calculates the number of slices required to produce the part(s), and where each droplet will be jetted, whether it be build material or support material, once the droplets have been jetted onto the bed, a roller spreads the liquid out, and makes sure it is a uniform thickness across the whole area.
The liquid is then cured by the UV light passing over the top of it, turning its state from a liquid into a solid.
As each layer is created, the bed drops down slightly, by so many microns each time.
This process happens again and again, until the part is finished, which can take many hours or even days.
Once the part(s) have been printed, they are easily removed from the printer bed with a scraper, and or other tools, dependent on the features printed.
The part(s) then go through post processing to remove the support material by means of a high-power jet wash, after which they are ready to be handled, and used with no extra curing required.
If required the parts can then be metal plated, dependent on geometry, and dyed if required! When using Vero Clear or Vero White.
