Hello again HN! 11 months ago I told you LitiHolo (I’m the founder) was working to create a 3D Hologram Printer, and asked for your input. It’s now live on Kickstarter! These are true laser-recorded holograms, and we are starting small an

Yes, this would work well! Might have a more narrow viewzone, because the light field from those is fairly narrow as I recall.

Yes, we're taking a radical approach to make it something that can be more accessible. Kind of like the first Makerbot, but for holograms. The SLM choice will be part of trying to get the right performance/cost mix. The printer w

Right now our full-color kits only handle 2"x3". We are planning to come out with a full-color 4"x5" upgrade in the near future, with stronger lasers. However, all of our hologram film is full-color sensitive, including

Yes, might be interested in getting your assistance. Send an e-mail through the info (at) litiholo address, and mention you reached out on HN. Anticipating the first printer will be single-color, just to keep it simple. Then as quick to c

Our plates should be fine, as long as the conditions are consistent during exposure.

Met Jason many years ago when the Museum of Holography was shutting down. Amazing that he is still there, although I think he was in a different location when we met. Our 3D Hologram Printer is working to bring hologram-making like this to

That would be cool! Personal favorites would be Big Sur or NYC skyline. Stay tuned on the LitiHolo site for hologram printer details as we get closer!

The 3D Hologram Printer we are building does exactly that!

Depending on the way the hologram is printed or created, the hologram recreates the full wavefront, so the hologram replays the image without needing to know how your head is oriented. Will need to look up beer pump logos. Interesting.

Roger that! Trying to convey the concept, but the goal is certainly to outperform.
74.
by hologram-paul 7y ago
For the current kits, you are correct. For the 3D Hologram Printer, we will be able to open it up a lot more.

by hologram-paul 7y ago
Thanks! The holograms are pretty cool too!

by hologram-paul 7y ago
Our current kits would not work for that, but the 3D Hologram Printer that we are building could make those. The printer takes multiple images, each from a slightly different perspective (maybe 1 degree apart each), and then synthesizes the

We put all of our film on glass plates for the stability. We currently don't have a film-only option, because the success/quality for getting good holograms has not been as good. Our film plates are pretty competitive when you co

The unique self-developing hologram film captures the interference pattern of the laser light, which is the hologram. The optical layout for our kits reduces the vibration issues by using single-beam setups. I've actually made a hologr

I like where your head's at!

Right now targeting 48 angles/slices/images per hologram. Want to give a smooth "look around" feel. Limited by the hardware/cost choices that get us good quality vs. reasonable cost. Size of the holograms initially

by hologram-paul 7y ago
Should work, I think.

As hologram technology gets more wide spread, the price will be able to come down. Right now a <$100 Hologram Kit replaces what used to cost $1000's. So we're moving in the right direction!

by hologram-paul 7y ago
We are building a 3D Hologram Printer so that you can have that kind of technology right at home! Or entrepreneurs could set up new businesses so that this is available easily and as common as a print shop.
84.
by hologram-paul 7y ago
Yes, agreed! Although I tell people that what we are doing currently with the Hologram Kits is helping to create the next generation of hologram engineers. So they can build what we dreamed of! And a 3D Hologram Printer will get us one ste

Possible! If you make a 3D hologram of a 2D plane, it will still be 2D, but at a particular depth location. This makes my head hurt to think about, though.

Yes, I lived in NYC for many years, and actually made hologram portraits in the basement of the old Museum of Holography off Canal Street. One of our big pushes for the 3D Hologram Printer is to put this kind of technology into the hands of

That is very much how the hologram printer works! You take many images, each from a slightly different perspective (maybe every 1 degree), and the hologram synthesizes them into the full 3D image. The other cool part is the holograms can h

Our current hologram film size is 2"x3", 4"x5", and we just introduced 6"x8". So planning to start in those sizes, but it is theoretically possible you could tile them to get larger area. Ultimately, it could

by hologram-paul 7y ago
Thanks. I think hologram portraits are the next direction, but any ideas on what else would make it more interesting?

Hey HN! LitiHolo (I'm the founder) already makes the Hologram Kit and Full-Color Hologram Kit. They let you make real laser holograms on an average desktop with self-developing film. But we want to do much more, and are working on a
