By Michael M. HoughtonPublished May 08, 2019 09:16:22Housed in a former industrial warehouse, a tiny, low-key facility near the University of Queensland campus, is a printer called the HP Print Nails.
It’s not the kind of printer you would buy for a few dollars at Walmart, but its purpose is to make ink-free paper from scratch, and that’s what it does.
Houghton, an industrial chemist, and his colleagues at the Queensland University of Technology (QUT) have been tinkering with inkjet printers for a while.
They wanted to print ink in a way that wasn’t harmful to the environment, and for a price that was far less than the cost of the ink itself.
But as they looked into what it took to make a printer from scratch that worked for a household, they discovered the cost is a lot higher than it appears.
Huffton and his team found that their printer’s ink was almost four times more toxic than it was worth.
A lot of that is due to the way ink is handled.
It has to be heated to an intense temperature before it can be heated into solid paper.
That process, called thermal shock treatment, destroys many of the structural proteins that make ink stick to paper.
“Our main goal is to print from a material that is not toxic,” says Huffman.
“Our main aim is to be as eco-friendly as possible.
We’ve taken a material we know very well and used it for ink, and made it out of scratch paper.”
The paper they’re using is the same paper that was used to print books and other printed materials, but they’re also using it to print their own ink.
The team used ink from the University’s Advanced Optical Materials (AOM) research facility, which is a partnership between the university and the Australian Research Council.
The ink is a non-toxic material that’s been manufactured at the AOM facility for a long time, and Huffman says that’s why it’s so safe.
“The AOM is actually very good at curing ink.
They’ve had that technology for a number of years and the ink has been very good,” he says.
“They’ve got a lot of facilities to cure the ink.
It will cure within a few hours, so we’ve been able to keep that technology and keep it going for many years.”
The team printed some of their ink in water and water-based ink, which both work very well.
But Huffman wanted a material with a higher density of ink than the water- and water vapor-based solutions they used.
That meant making a high-density ink using a combination of water, water vapor and a metal catalyst.
The metal catalyst is made from zinc.
Huffman and his collaborators used it to make an adhesive that they added to the ink before printing it onto a paper.
The resulting paper was about a third the density of the water that was in the ink, making it about one-third as thick as standard paper.
This is just one example of how the team is making a material from scratch.
Huffson says that he and his research team are constantly tweaking and improving their process to make it even better.
“There’s so many different things that go into making these materials that are very, very, unique.
We really have no idea how to make anything that is this good,” Huffman said.
The HP Print-Nails was made using a special process known as inkjet lithography.
This means the ink is made on a metal plate, with the plates themselves being coated with a special coating of zinc.
This process allows the ink to stay attached to the metal plate without the need for any special tools or chemicals.
It took three years to print the ink in the first instance, and the team was not able to print it with just water.
They needed to add a layer of water to the plate to get the ink working, and then add more water to get it to stick.
That layer is what made the ink stick, and they also added more zinc to get more ink to stick on the surface.
After printing the ink on the first layer of the metal, Huffman added a layer on top of the second layer, and finally he added a third layer on the top of it.
Once all of the layers were printed, the ink could be removed from the plate and the print would be finished.
“We print on a piece of metal called a sheet.
That’s basically a piece that’s printed on top,” Huffmon said.
“You just take the sheet and apply pressure to the sheet, and it slides off.
You print it, and you just print it on top.
You don’t even have to change the sheet itself.
It just slides off.”HP Print-Ns are also able to hold up to eight times their original density, meaning they’re able to
