The ProJet 4500 3D printer, and one of its creations

Although the things that can be done with 3D printers are certainly amazing, many 3D-printed plastic items still have a certain "look" to them. This is largely due to the fact that each item is all one uniform color. That apparently no longer has to be the case, however, as 3D Systems has unveiled its ProJet 4500. The company describes it as "the industry’s only continuous tone full-color plastic 3D printer."  Read More

Like most other fabrics, silk is colored with dye. Unfortunately, the dyeing process results in wastewater laden with toxins. Now, however, scientists from the National Chemical Laboratory in India are developing an alternative. They're feeding dye to silkworms, which in turn are producing pre-colored silk fibers.  Read More

Shapify statues are made from 3D Kinect scans at 1/20 full scale (Photo: Shapify.me)

To make a three-dimensional color statue of yourself, you could grab a chunk of marble and enlist the services of a sculptor and a painter, or you could take the simple approach and use a 3D scanner and a 3D full-spectrum multicolor printer. Since the first option is expensive and time-consuming and very few of us have access to the equipment for the second, Shapify has launched a service that lets users scan themselves at home, using a Kinect.  Read More

Panasonic has developed a new technology which could replace the color filters used in most digital cameras. Its new Micro Color Splitters work by separating colors at a microscopic scale using diffraction, rather than filtration. This means the technology has the potential to vastly improve low-light photography, and double a camera's color sensitivity.  Read More

The NODE is a rather clever device. It’s a multi-function remote sensor, that links via Bluetooth with a paired smartphone. Different sensing modules can be swapped on and off of the main NODE platform, allowing it to serve as a 3-axis accelerometer, magnetometer or gyroscope. Additional modules were promised when the device was first announced, and an interesting one is now on the way. It’s the NODE Chroma, and it allows users to copy any color they encounter, for later use in things like paints or computer graphics.  Read More

Scientists have developed a new process for changing the surface color of gold and other m...

Although a great many people like the “prestige” that comes with the natural color of their gold jewelry, teeth or vacuum cleaners, things are about to get a little more complicated – scientists from the University of Southampton have now devised a technique that causes gold (or other metals) to be seen in a variety of other colors ... green gold, anyone?  Read More

A sample of the biomimetic film, and a morpho butterfly

Butterfly wing material is somewhat like spider silk, in that they’re both animal-produced substances which scientists are very interested in copying. In the case of butterfly wings, it’s their ability to brilliantly reflect light in a variety of iridescent colors that could prove particularly useful to humans. Researchers from the Korea Advanced Institute of Science and Technology (KAIST) are reporting success in replicating the reflective properties of the insects’ wings, using tiny glass beads.  Read More

The Chromatic Typewriter was initially intended to be purely conceptual

A typewriter that paints? Artist Tyree Callahan modified this 1937 Underwood Standard typewriter to do just that, replacing each key with a different hue that can paint on paper. A chromatic typewriter isn't by any means practical (the keys have to be manually reloaded with paint) - but the concept is still pretty interesting. So, how did he come up with the idea to create the typewriter, and once he had that idea how did he turn it into a reality? We had the opportunity to talk about the project with Tyree.  Read More

Suppose you just love the sage green color of your new desk blotter, and think “If only I could instantly make my whole office this color.” Well, now you can ... sort of. The designers over at ThinkGeek have created a gizmo called Huey the Color Copying Chameleon Lamp, that automatically “reads” any color that it’s placed upon, then glows in that color.  Read More

Excess carbon dioxide in the atmosphere has certainly become an environmental concern in recent years, but researchers from Germany’s Fraunhofer Institute for Environmental, Safety and Energy Technology are now experimenting with a process that uses CO2 to process plastic products in an environmentally-friendly fashion. They have discovered that by compressing the gas, it can be used to impregnate plastic objects with dyes, antibacterial compounds, or other substances. Traditionally, toxic solvents have been used for coloring plastic items.  Read More
