It is a question that has haunted the sleepless nights of most 3D printing device developers: how do you convince home users to purchase a 3D printing device? As it turns out, additional individuals may already have a 3D printing device at their fingertips without in fact understanding it. MIT-backed startup Lumii has made a new optics algorithm that lets users print full color 3D holographic photos, with ideal 3D parallax movement, on regular 2D inkjet printing devices. 3D is appearing eachwhere, in fact in the 2nd dimension.
This astonishing new 3D printing opportunity was shown off at Siggraph 2016, a desktop graphics and interactive techniques conference that was held in Anaheim, California in late July. Whilst packed with additional innovations than you can count, the Lumii booth as particularly talked of thanks to a rad interactive showcase. Visitors may let themselves be 3D scanned, after that the data was immediately reworked by Lumii’s hologram algorithm and printed on a regular Epson color printing device, the type you can find in any office. The results blew eachone out of the water, as the full-color holographic cards displayed a ideal 3D portraits.

This is especially astonishing for the reason the holographic effect is usually only made with special lenses or with materials that are placed on top of the photo. But Lumii does so with nothing else than an inkjet printing device and a custom algorithm. The resulting ‘light field prints’ in fact next true 3D parallax movement in all directions (unlike those crappy 3D cards we had as kids), meaning you can view a 3D image of each single angle.
This astonishing achievement has been accomplished by co-founders Tom Baran, Matthew Hirsch, and Daniel Leithinger, all MIT graduates. And as they explain, it’s far additional than only a gimmick. “A long-standing vision of the display research community has been to turn it into display surfaces with fidelity that is indistinguishable of reality. Our research is aimed at building progress in the direction of this goal, in particular by creating high-resolution automultiscopic light field displays capable of full horizontal and vertical parallax,” they explained in a research paper.

Whilst other researchers have achieved a few good results in that field may already, each 3D image can rapidly cost several hundred times additional than a regular color print. What’s additional, they are in addition quite limited when it comes to resolution. “The way that we do it is instead of via specialized optics like lenses, we use algorithms to take a 3D version — the kind of version that you can use in a program like AutoCAD or a CAD box — and we turn that into a special patterns,” Baran explained at Siggraph. “And when you print the patterns and lay them on top of one another, you get a 3D effect.”

To manufacture a holographic photo with these stacked layers, all they require is an off-the-shelf 3D scanning setup, such as Microsoft Kinect One, Intel Realsense F200, or Structure Sensor. “The output can be processed by Lumii’s light field engine, and printed as a hologram-like 3D film,” they say. Many commercially on the market photo printing devices can be utilized ,with a high resolution photo accomplished in as little as 15 minutes. Understandably, it was a massive hit at Siggraph, where hundreds of individuals let themselves be 3D scanned.
Whilst it looks like only a rad printing toy, Lumii is in fact serious of commercializing their algorithm as well. “Optimized light field displays that put inexpensive, high-quality, print and digital displays in the hands of users can turn it into amazing opportunities in human desktop interaction, 3D printing and making, medical diagnostics, media and advertisement, augmented reality, artistic expression, and beyond,” they argue. Especially the fact that little specialized equipment is necessary manufactures this a quite potent innovation.
What’s additional, they have got a lot of interest of different types of industries may already, which include of advertising and healthcare specialists. “You understand all those lightboxes in airports and malls, we are rolling out a print service in the coming months where you can take one of our Lumii prints, that is a rigid insert, insert it in one of those lightboxes, and you get what amounts to a full color holographic advertisement,” Baran said. To manufacture this a reality, they are already working on a web interface where individuals can upload 3D data to be processed for local printing.
