A unique new approach of printing functional materials with unparallel precision and repeatability. Technology called Ultra-Precise Deposition (UPD) is a nanodispensing method capable to print high density and high viscous materials with the resolution down to 1 µm in feature size and with high ratio of width to height after single pass. For this method material extrusion is controlled by a pressure, which means it is not supported with high electric field. Thanks to this there are no limitation if the substrate is conductive or dielectric.

EHD is a promising digital printing technology for going beyond the resolution limits of inkjet. Most examples showcase electronic or display related applications.
The three themes are closely linked since QDs can be digitally printed as color conversation materials atop blue microLEDs to enable wide color gamut RGB uLED displays without requiring a separate transfer step for each color.. This is an important technology as it simplifies the manufacturing step for microLED and thus removing a major hinderence.
As microLEDs inevitably shrink in size, the micro-bumping requirements for the microLED dies becomes more challenging. Direct wafer-based printing based on gravure offset techniques offers a promising solution in this regard. Indeed, this is another field where printed electronics can play a role.
Nano-Ops is commercialising an automated wafer-based process and fab-in-a-box based on the directed assembly technology which can 'print' features down to 20nm. Here, In the first step a pattern is first etched into a template wafer.

The progress of screen printing towards fine line printing has been incredible going from 100 µm features before 2010 to 70 µm to 2015 to 40 µm in 2018 and now pushing - in development- towards 20 µm and less. In parallel, the wet thickness of the printed line have gone down from 12um or so in 2018 to now just 4um.
To scale up microLED displays to large areas, smaller displays can be titled. Because microLEDs can be truely edge-less devices, the tiling can function, yielding a seemless look.
Stretchable Electronics and inks for durable wearable electronics. These inks can be printed on TPU films which can be bonded to fabrics. This results in devices that stretch without cracking and maintain excellent electrical properties. Examples include biometric sensors & fixed resistance heaters
Silver nanoparticle inks improve every year. These improvements are often incremental, but very important. One ever-present direction of development is towards inks which offer ever higher conductivity levels at a low curing temperature and a short curing time. This a critical figure of merit because it opens more substrate choices, saves time, and lowers energy consumption costs.
