Dublin researcher awarded €2.5M to develop 3D printed long lasting battery

Feb 15, 2016 | By Tess

A research team at Trinity College Dublin’s Amber Science Centre has recently been awarded a grant of €2.5 million to continue the research and development of their 3D2DPrint project, which consists of a new type of long lasting battery that can be housed and hidden within any type of material, from the human body in 3D printed cardiac devices, to clothing, to smartphones.

The 3D2DPrint research project is being led by Professor Valeria Nicolosi, an expert in nanomaterials who has received the coveted European Research Council (ERC) Consolidator Grant no less than four times. Now, with more than €11 million in funding over the past five years, Nicolosi and her growing and multidisciplinary team are making some impressive advances.

Professor Valeria Nicolosi

Nicolosi explains the significance of the ERC funding, “Since 2011, the first year of my ERC Starting Grant, my group has grown from three to 25 people. The ERC grants I have been awarded were not only important in helping fund our research and grow our team, but to also help leverage more funding and realise partnerships with large multinationals. What is key is that these Grants allow us to take the next step with our research – whether it is the licensing of technology or starting up a new company.”

The high-tech battery being developed is being created through a combination of 2 dimensional nanomaterials and 3D printing technologies, which are being used to create custom and complex objects to house and enhance the capabilities of the nanomaterials.

Eventually Nicolosi and her team are hoping to introduce fully customizable batteries, which could be used for any number of applications, from a 3D printed smart watch, to smart textiles, to cardiac devices, which could also be 3D printed.

The new and extremely long-lasting batteries would also offer an alternative to the commonly used Lithium-ion batteries which are embedded in most consumer electronics but which pose certain risks, such as flammability.

“The work Prof Nicolosi and her team are doing is at the forefront of their fields, and this grant will help them take the next step in combining the team’s expertise of advanced materials methods to integrate nanomaterials into 3D-printed energy storage devices,” said Prof Michael Morris, director of Amber.

Nicolosi has been working as an ERC research professor at Trinity College Dublin and as a principal investigator with Amber since early 2012. The Advanced Materials and BioEngineering Research centre is funded by the Science Foundation Ireland (SFI) and has as its aim the partnering of science researchers with industry, as well as making Ireland a fertile and competitive place for innovative research and development.

Philip Crump

Philip Crump is a recent graduate of the University of Southampton with a BEng in Electronic Engineering who’s also into amateur radio, electronics, and programming.

While his full-time gig is as a Lead Hardware Engineer at Telemetricor Limited, he’s also a Volunteer RF Engineering Consultant for Southampton University’s UOS3 Cubesat Project. Along with all those pursuits, Crump is also a photographer who needed a camera that would operate in the low temperatures environment encountered at altitude.

But here’s the problem: Crump was disappointed when he did cold-temperature battery tests with his Canon SD1000 camera. It seems once the batteries in the camera were chilled, they’d only operate for some 34 minutes at a time versus the nearly five hours they’d function at room temperature.800px-20150113-somakeit

So Crump used 3D printing to build an alternative power supply solution that would work in icy temperatures. His Canon SD1000 doesn’t accept being powered up via its USB port or provide additional accessory sockets, but fortunately, the camera’s battery door does include a hole for wiring. So Crump built what he calls a “fake battery” for the camera which uses a DC supply. As the balloon which would carry his camera aloft already includes a battery pack, Crump’s plan was to tap into that source to power his camera.

That led the designer to create a 3D printed battery emulator that takes the place of the stock battery pack. Bare contact wires inside t300px-20150113-print2-printerhe holder run out of the camera and then to a voltage regulator which converts the six-volt output of the balloon battery pack down to the 3.9 volts his camera needs to operate correctly.

Crump says one major challenge of the project was to be certain that his design worked to make a reliable connection with the battery contacts deep inside the camera. His answer was to build a 3D printed, battery-sized holder that would fit snugly in the limited space available.

He got in contact with the guys at So Make It, a Maker and Hackerspace in Southampton, who let him usea Lulzbot Taz and print the model he created in OpenSCAD. You can check out Crump’s solution and find out where to get the files at his website,

Graphene 3D Lab unveils first 3D-printed graphene battery

Oct. 24, 2014

Graphene 3D Lab, based in Calverton, New York, announced in September that the company submitted a provisional application for a patent to the U.S. Patent and Trademark Office for recent innovations in the materials and methods of 3D printable batteries. Yesterday Graphene 3D released a brief video outlining details of the 3D printed battery development.

Graphene can be easily mixed with thermoplastics commonly used in FDM 3D printer. Currently the company is working on designing a mixture of plastics and graphene that can be turned into nanocomposite material filament. The graphene-enhanced materials can be used within any standard FDM 3D printers to fabricate a functioning battery which may be incorporated into a 3D printed object during the build process. These filaments possess functional properties including thermal and electrical conductivity and would be useful to produce variety of sorts of 3D printed batteries.

The key to power any electronic object is to have it attached to a power source. Currently Graphene 3D’s 3D printed batteries can produce the same amount of power as a common AA battery, which could easily provide enough electricity to power the sort of small transmitters or sensors.

The company’s 3D printed graphene battery can potentially outperform a conventional battery because of its shape, size and specifications that can be freely adjusted to fit the particular design of almost any 3D printed device.

Dr. Daniel Stolyarov, chief technology officer and co-founder of Graphene 3D Lab expects the company will offer the graphene-enhanced filaments to consumers later this year so they can print their own batteries. In the long term, Graphene 3D Lab plans to build a bespoke plug-and-play 3D printer which will allow users to 3D print battery by simply pressing one button.
