The technology can quickly churn out embossed images and even braille for the visually impaired

The Casio 2.5D 3D printer looks like a regular commercial printer but instead of using just ink, it uses heat to emboss information. This process lets the device churn out images and Braille characters that can be touched and felt in mere minutes.

The secret is in the paper. Sandwiched between printable layers is a type of plastic that expands when heated. Using infrared and heat absorption by black ink, specific areas in the paper expand under a halogen lamp.

In addition to the embossing, the printer also has inkjet heads, allowing it to superimpose colored images to the embossed figures.
