Almost everybody knows that 3D-printers can print anything you want. Some people want a snack, and they prefer chocolate. This is not something impossible anymore. Most modern 3D-printers as the main material used plastics because it melts at relatively low temperatures and is easily deformed.

Chocolate print

Scientists at the University of Exeter (England) have noticed that chocolate has similar properties. These considerations led them to build a computer-controlled 3D-printer that prints with chocolate. Of course, not everything went smooth, working with chocolate was a bit more complicated. It is not as flexible, so pouring it through a standard feeder was difficult, and maintaining a stable form of the printed prototype was not easy, too. To fix these issues, the authors developed intelligent systems of heating and cooling, rather complicated and expensive to maintain. This makes the idea of 3D-printers chocolate machines going into mass production unrealistic in the nearest future. However, the service of printing chocolate figurines, whether it’s household items or jewelry, might well arise. Girls will definitely appreciate a chocolate necklace for Valentine’s Day!

Samsung Electronics announced the launch of ML-4510/501X series printers expanding line of printing solutions for the B2B sector. The new models are designed for small and medium-sized businesses, these are monochrome laser printers. The printing speed of Samsung ML-4510ND is 43 A4 pages per minute, while the ML-5010ND and 5015ND models produce up to 48 pages per minute. First page out time is 7.5 seconds in ready mode and 16 seconds from standby mode.

The new printers are equipped with 600 MHz dual-core processor and have 1 Gbps network adapter. The dual-core processor also manages the printing preparations and simultaneous printing of various tasks, so the company believes that the devices are suitable for workgroups of 10-20 people. With two 100-sheet paper trays, total input capacity of Samsung ML-4510/501X series increased up to 620 sheets.

In printers of Samsung ML-4510/501X series, the drum needs to be replaced after printing 60,000 pages, and high capacity toner cartridge, Samsung ML-501,X allows you to print up to 20 000 pages. To save toner, you can select ECO mode, which automatically enables duplex printing and skips blank pages. Samsung ML-4510/501X series printers produce noise level of less than 54 dBA and are operated using a 4.3-inch LCD touch screen (the ML-4510ND and ML-5010ND also have a numeric keypad). In addition, the USB port in the models Samsung ML-5010ND/5015ND makes it possible to print from a flash drive.

How do you like the idea of moving the wall, an integral part of today’s social networks, to the real world? Liat Segal is obviously a fan of social networking who wants to leave messages for friends not only on the virtual wall, but also on quite tangible one. To do so, Liat invented Cellular Wall Printer, a device resembling good old impact printers.

The device is a combination of an Android-smartphone and servo motors, the latter control the movement of each of the seven markers. An “adapter” between the phone and motors is the IOIO programmable board. The Cellular Wall Printer receives messages on a smartphone (SMS, Twitter or Facebook), which it prints on any wall (or surface, for that matter).

The inventor claims that the device copes with printing well even when the printer operator moves. You can get the whole idea by watching this video:
