Ultra-Precise Deposition (UPD) is an additive manufacturing process for fabricating conductive and non-conductive features at micrometer scale. The method is compatible with a wide range of materials, which makes it particularly suitable for rapid prototyping of high-resolution displays and its components. In this contribution we will discuss the means to control the process and give a number of examples that can be considered as building blocks for display-component prototyping, making the process more productive and cost-efficient. We consider materials based on silver, copper, and gold, as well as photoresists.
