#2Hello again HN! 12 months ago I told you LitiHolo (I’m the founder) was working to create a 3D Hologram Printer, and asked for your input. Well, we built it!
I've been involved with hologram printers all the way back to my grad school days (MIT Media Lab), and have built custom industrial versions for in-house commercial hologram work. But more recently LitiHolo has been focused on simple educational holograms kits. With this 3D Hologram Printer, we are kind of bringing the two together -- a simple hologram printer that makes the technology more affordable and accessible.
These are true laser-recorded holograms, and we are starting small and simple to get things off the ground (think Makerbot for holograms). Would love your feedback on how we can continue to make hologram technology like this more accessible, as well as ideas for possible killer apps and use cases.
Here's our previous HN post from 12 months ago: https://news.ycombinator.com/item?id=22616010
And full disclosure: we have launched a Kickstarter project for this, but would appreciate your input whether you back the project or not.

Good luck on your kickstarter. Hope you guys achieve your goals and ship this amazing tech!
I tried searching for the term "hogel size" I assume it is somewhat equivalent to resolution. Can you expand on it and tell us what are the limiting factors around resolution and how it can be improved in the future?
I am now curious how commercial sticker size holograms are printed.

#5The part of me that is still a kid in the 90s that thought DBZ shirts were the epitome of style is thinking this is the coolest thing I've ever seen.

Thanks! The hogel size is physically determined by things like the aperture size (in our case 1x1mm to start, with a stretch goal for 0.5x0.5mm), but also laser power, and just how long it takes to print each hogel and as a result the full hologram. Double the resolution is 4X the number of hogels.

Holograms have a way of doing that to people! Thanks.

#8Wow, it's a long time since I saw a site without SSL.
Probably want to add that, not only for avoiding the red key at the top but for performance reasons.

#9Cool idea. But I'm not seeing a practical application outside of the "hey this is cool!" factor.

Roger that! Will get on that, and thanks for the heads up.
