TTP, a UK-based research and development company, has introduced its new Vista Inkjet process, which the company believes can one day revolutionize the manufacturing of cars, planes and appliances, amongst other industrially produced products.
The Vista Inkjet process developed by TTP is capable of printing with standard industrial paints. TTP states it has already tested Vista Inkjet successfully with cellulose and two-part part polyurethane paints used for car and aircraft body manufacturing. After testing such high-end uses, the company explains this opens up many other possible applications including the use of thermoplastic fluoropolymer paints like Kynar for decorative finishes on architectural metallic structures.
TTP states it is also exploring the printing of low cost and high functionality materials for ceramics, textiles, security and brand protection along with high conductivity patterns and 3D printing.
TTP’s patented print head design overcomes what the company describes as the limitations of existing inkjet printing processes, restricted by ink formulations and the use of closed chambers and narrow channels. Instead, Vista Inkjet is based on a planar construction that allows free-flowing ink circulation and accurately controls the movement of the nozzle plate to eject droplets, from 0.5pl (pico litres) to over 1nl (nano litre).
TTP explains this means that fluids with large particulates and high viscosities can be used along with aqueous pigmented inks and a range of solvent inks such as alcohol based fluids, ethyl acetate, MEK and Dowanol. Motion of the nozzle plate is controlled by customized electrical drive signals to eject droplets on-demand or on a continuous basis.
TTP reports its prototype array of 128 Vista nozzles has delivered drop placement accuracy with a standard deviation of just +/- 3 milli-rads. Print heads can also be designed with specific nozzle diameters, pitch and number of rows for different inks, paints and applications. And with the inertial transfer mechanism and fluid recirculation, the ejector system features priming, self-cleaning and refill attributes.
“We have taken the principles of inkjet printing and re-invented the ejection mechanism and print head to create a potentially disruptive technology for digitally printing industrial paints, opening up exciting new opportunities from customizing car and aircraft bodies to creating architectural finishes and printed electronics,” said Dr. David Smith, head of business development for Vista Inkjet at TTP. “As well as providing greater flexibility, the process also saves time and money and reduces waste.”
TTP is currently looking for partners to commercialize the technology.
