3D printing for the day

The BBC has an article by Leo Kelion about the latest at the CES show in Las Vegas, Nevada:

A desktop 3D printer that uses paper, ink, and glue to create highly detailed objects has been unveiled at the CES tech show. Mcor said it was the first time such technology had become available in a machine suitable for classrooms and offices.
The device is one of many new 3D printers announced. Other launches include a sub-three-hundred-dollar model and a machine that creates circuit boards.
There is still uncertainty about the sector as a whole. Share prices in many of the firms involved sank in 2015, over concerns the industry had been over-hyped. But shipments are still forecast to rise from about a quarter-million devices in 2015 to two-and-a-half million units in 2018, according to research firm Gartner.
The Mcor Arke creates color models at a resolution of 4,800 by 2,400 dots per inch, providing higher detail than many 2D printers. It does this by using razors to cut plain paper into shape, inkjets to colour it and then glue to join all the layers together and to laminate the final object. The firm believes its use of normal paper gives it an edge over rivals.
Mcor says it has already received pre-orders for more than twenty-five hundred units of the new printer "Because paper is used with other non-toxic materials, no special ventilation or disposal systems are needed, just an ordinary recycle bin and none of the messy powders or melting plastics used by other 3D printers," it said.
The machine, targeted at schools and offices, is due to go on sale before July of 2016, and will cost six thousand dollars. That is about half the price that Mcor had been charging for a much bulkier model.
"Nobody can match Mcor's resolution in terms of color," said Daniel O'Connor from TCT magazine. "This printer's resolution is twice that of any industrial machine, and those industrial machines typically cost over fifty thousand dollars."
The Da Vinci Mini is XYZprinting's cheapest model to date. It makes objects by squirting hot plastic to build them up layer by layer, a basic technique that means creations can look a bit rough and ready. But the company suggests it could serve as a starter device.
"Making 3D printing technology affordable and accessible has always been XYZprinting's biggest goal so that we can break down the barriers to ownership," the firm's chief executive Simon Shen told the BBC. "There are other obstacles, apart from price, such as speed and multiple colors, but it's just a matter of time before every home and office has at least one 3D printer." The Da Vinci Mini can create objects up to the size of a six-inch cube. O'Connor said it was significant that an established brand was now offering a 3D printer for less than a games console. "The machines XYZprinting are producing may not be the highest quality in the world, but they more than fill the void for what people want for schools and other educational purposes," he said.
There is also much higher-end gear at CES:
3D Systems has a model that can print complex objects out of titanium, stainless steel and nickel.
The ProX DMP 320 is targeted at the aerospace and automotive industries and costs up to seven hundred thousand dollars.
Nano Dimension, an Israeli start-up, is demoing a printer that uses inks containing nanoparticles of silver to create complex circuit boards. It says the Dragonfly 2020 can help gadget-makers bring products to market more quickly by making it easier to test the electronics involved. 

Other exhibitors include:Glowforge, which has a printer that uses a laser that can both cut and engrave wood, leather, fabrics, and acrylic
Voxel8, which has developed a 3D printer that adds pre-made electronic parts and wiring to objects as it creates them
Polaroid, which has revealed a 3D printer with a built-in camera that transmits photos via wi-fi, so owners can monitor progress from afar.
Makerbot, one of the biggest 3D printing brands, is also in attendance. Its latest product, the Smart Extruder+, may not seem as eye-catching as those of its rivals, but it marks an important step for the business. The $199 device allows users to upgrade the part of their machine that melts plastic and pushes it through a nozzle to build an object. Makerbot says that its updated version of the Smart Extruder will be reliable. It includes a sensor that can pause the printing process if it detects the plastic has jammed or run out, and sends an alert to its user's smartphone. The component is itself a replacement for an original version, launched in 2014, which customers complained had a tendency to fail sooner than expected. Last year, a class action lawsuit was filed over the matter that claimed the firm had knowingly sold a product it knew had problems. Affected owners were particularly annoyed that Makerbot had only offered a ninety-day warranty for the device. That has been extended to six months for the Smart Extruder+.
"Makerbot had pretty bad publicity over the original one," said O'Connor. "It really needs to focus now on improving its technology and making it work rather than launching fancy new machines, and I think that's what it is doing now."

Rico says he probably won't own one of these dinguses, but it's nice to know they're available...
