An MIT startup has made a new kind of 3D hologram. Using scanned images and an inkjet printer, Lumii's approach prints images in layers onto clear paper that, when put together, form holograms.

The first step is to choose a smoothing spray that is designed for the type of material you are printing with. There are different smoothing sprays for different 3D printing materials, such as ABS ...

A one- or two-layer thick 3D print will stick to the sheet, which can then be laid print-side down onto a t-shirt and transferred to the fabric by ironing it at maximum temperature.

Normally, in a 3D printer, the inkjet moves around in two dimensions, slowly printing one 2D layer before moving up to print another layer on top…. But using this technology, you could have a whole ...

Previously, researchers could only print this material, known as graphene, in 2D sheets or basic structures. But engineers have now 3-D printed graphene objects at a resolution an order of ...
