Utilizing Polyjet 3D Printing technology to create molds can be a great option under the right circumstances. These printers use a photopolymer to layer by layer build a molds core and cavity. The mold can be put into a mud base and injected with the actual material that the end use part will be made of. By doing this mold makers can produce parts that are high quality at a fraction of the cost. Granted these molds are not as durable as tradition injection molds but for low volume production 3D printed molds can be a major cost reduction tool.
