HP's printer uses multi-jet technology to build an assortment of items based on tiny voxels – the 3D equivalent of an image's pixel. With this ultra-fine control, the designer can adjust the item's geometry down to roughly 50 microns, or roughly the thickness of a human hair. The result is the ability to make items that would be very hard, if not impossible, using traditional manufacturing techniques. 

The printing process starts with the printhead forming patterns on the building stage using HP's two raw materials. The fusing agent defines the object's general shape and cross-section while the detailing agent adds fine details. 

To solidify the raw materials, banks of intense halogen lights shine on the substrate. For the item to comply with the designer's specs, the printer maintains a constant temperature across the object. The system uses a thermal camera to measure the temperature of the item and adjusts the temperature accordingly. 

The 4200 can lay down layers that are 80 microns thick. It is capable of building more than 4 liters per hour. The 4200 can print a sheet consisting of small parts or a single item measuring up to 15 x 11 x 14.6 inches. It tops out at nearly 40 liters of build capacity. 

In HP Multi Jet Fusion technology, production is based on polyamide grade materials called PA 11, PA 12 and PA12 glass beads. HP's FJ 4200 is well suited for companies that manufacture 130 to 600 items a week.
