10. A new way to 3D print
The HP Multi-Jet Fusion 3D 3200 Printer uses a sintering process that heats to fuse or compact the build powder into a solid shape without liquefying the powder. The chemical agents control the heating process. A layer of plastic powder is rolled onto the build bed. The powder is kept at a high temperature to speed the print process when it begins. At least two chemical agents are sprayed onto the layer in the build pattern. One agent absorbs the heat needed to sinter the plastic powder. The other agent stops the heat absorption process to ensure sharp part details. It takes about a light second to cure the exposed area.
