1 - Yes, we are currently doing this 2 - Right now our focus is on flat substrates, curved surfaces are a little trickier 3 - Any pure metal or alloy system that can be electroplated would be compatible with our approach. Aluminum and Titanium are difficult but not impossible. We're focused on copper as our first commercial material but have other material systems in development. 4 - Our current pixel size is 33 microns, ~50micron negative features should be doable. Controlled wick structures are actually a really good application of the technology 5 - Our primary business model actually is to offer print services to our customers. Feel free to reach out to me via email in profile if there's an application you'd like to explore
