Open-source solar-powered 3D printers can go almost anywhere

Open-source solar-powered 3D printers could bring 3D printing to remote areas, Professor Joshua Pearce at Michigan Technological University has proposed.

One version features an array of solar photovoltaic panels and a stand-alone printer that could be stationed in a sunny schoolyard and print anything from consumer toys to science lab equipment.

The second system is smaller and fits in a suitcase, based on a RepRap 3D printer and can thus replicate itself and make parts for larger printers. And it can go almost anywhere.

3-D-Printing Bio-Electronic Parts
With new “inks” containing semiconductors, researchers have been able to print LEDs for the first time.
Printing Circuitry for Bionic Implants MIT Technology Review

• By Katherine Bourzac on December 1, 2014

A 3-D printer can already make a prototype or spare part out of metal or polymer. Researchers at Princeton University have now taken an important step toward expanding the technology’s potential by developing a way to print functioning electronic circuitry out of semiconductors and other materials. They are also refining ways to combine electronics with biocompatible materials and even living tissue, which could pave the way for exotic new implants.

With cartridges full of semiconductor “inks,” it should be possible to print circuits for all sorts of tasks, says Michael McAlpine, an assistant professor at Princeton, who led the work. To demonstrate the feat, the researchers printed a light-emitting diode within a contact lens.

Oooh - are they 3D printing with carbon nanotubes yet?

Sigma Labs and Additive Industries Want to Make Metal 3D Printing Better

Advanced quality inspection process developer Sigma Labs has signed a technology cooperation agreement with 3D printing equipment manufacturerAdditive Industries. Sigma Labs is the latest additive manufacturing development company to join Additive Industries in its “AddLab” shared resources technology laboratory.

Santa Fe, New Mexico’s Sigma Labs is a leading developer of high tech, in-process, non-destructive quality inspection processes for metal-based additive manufacturing companies. Its line of advanced PrintRight3D software can reduce machining time, post-processing and help prevent misprints and the production of faulty parts.

Yale working with Organovo to develop 3D printed organs with bioprinted blood vessels

Researchers at Yale School of Medicine’s Department of Surgery and Yale School of Engineering and Applied Science have joined forces with a leading three-dimensional biology company [Organova] to develop 3D printed tissues for transplant research.

As the number of donors for vital tissue and organ transplants decreases worldwide and the demand for transplants increases, 3D bioprinting technology offers a solution to a long-standing and growing problem. “This field may provide a unique and new opportunity where we can print 3D organs that can supplement or replace the shortage of organs out there worldwide,” said Dr. John Geibel, vice chair and director of surgical research at Yale School of Medicine.

Organovo’s 3D human tissues offer many advantages over standard cell-culture platforms due to the fact that three-dimensionality is achieved without dependence on biomaterial or scaffold components that would not be found in native tissues.

First Copper and Bronze: There’s Now Brass 3D Printer Filament

The ingenious chemists at colorFabb have developed yet another metal-infused 3D printing filament: brassFill.

As you might imagine, it’s made of a mixture of a standard polymer (PLA) with fine brass particles. brassFill prints can be polished using conventional techniques to develop a bright, shiny finish as you can see in the image at top.

3D printing technology may be some way off producing fully functional household appliances, but tiny steps are being made toward helping us out with our domestic duties. Hoover has teamed up with MakerBot to today unveil two designs for vacuum cleaner accessories, freely available to all through 3D printing marketplace Thingiverse.

That's a clever idea. But you still might get the Secret Service paying you a visit ;-)

Researchers 3 Years Away from Commercializing Pure Graphene 3D Printers

As we’ve mentioned so many times in past articles, the convergence of additive manufacturing and the ‘miracle material’ graphene could have major ramifications for dozens of industries over the next several years. Because of this, researchers and companies are spending a great deal of time and money figuring out the best methods to 3D print graphene.

A group of researchers, led by Seol Seung-kwon at the Korea Electrotechnology Research Institute’s Nano Hybrid Technology Research Center (KERI) are at the forefront of this research. As we mentioned last month, KERI, a unit under the Ministry of Finance in South Korea, recently published a paper in Advanced Materials called ‘3D Printing of Reduced Graphene Oxide Nanowires‘.

Polyes Q1 - The Safest, Cool-Ink 3D Pen

Introducing Polyes

The safest, cool-ink 3D pen
Why did we build this?

The 3D printing pens that currently exist on the market are not easy to operate and unsafe — take for example, all pens using ABS/PLA materials that give off unpleasant odors and the risks of getting hurt by high temperatures. We wanted to address the aspects of safety and convenience by developing a pen that uses photo-polymer as ink, which solidifies under the LED light.

How It Works:

Unlike other 3D pens, there are no hot parts, no melting plastics and thus no unpleasant smell.

Polyes Q1 adopts the LED, which nearly does no harm to people’s eyes. The pen has photo-polymers inside, and it solidifies immediately when exposed under the LED light.

There’s also a tilt sensor inside, and together with child-safety switch, it could prevent kids’ eyes from being exposed to light. Additionally, we've designed integrated control buttons by moving the speed control key and the backwards to the line of the power indicator to make it more convenient. In short, we focused our efforts to make Polyes safer, more user-friendly and convenient.
