Researchers from Michigan Technological University have developed an open-source parametric 3D printed slot die system for thin film semiconductor processing. By using the 3D printed system over a commercial one, users could make cost savings of over 17,000 percent.
Slot die coating is a technology used to deposit a variety of liquid chemicals onto glass, stainless steel, or plastic substrates. Its myriad applications include solar photovoltaic cells, flat panel displays (LCD, OLED, and flexible), solid state lighting, and printed electronics sensors. The coating method can also be used to produce RFID tags, fuel cells, and lithium-ion batteries.
