⭕ This is a Zcorp model Z406 color 3D printer. The Z406 rapid prototype printer uses plaster powder and a liquid binder. The Z406 is much faster and much less costly to operate than the plastic media 3D printers from Stratasys or MakerBot. The Z406 also does not require any support structure to be printed as the Z406 fully supports the model with the unused plaster powder. After the 3D model is built and removed you manually recycle the unused plaster powder back to the supply side. All the unused powder is recycled, there is no waste. The Z406 can print in color or in white (clear binder). Third party clear or color binder works great. Included is the Zcorp anti-static vacuum and the depowder station. The depowder station is used to remove the powder that might be trapped in corners or in fine detail. The Z406 was purchased new in 2012. I will include several containers of plaster powder, you will need to buy liquid binder and other supplies. You will receive the Z406 printer, depowder station, anti-static vacuum, some supplies, operators manual and PC software. The Zprint software for PC prepares the 3D model for printing. Can help with delivery or collection.
