3D printing allows for creating unique and complex objects, but detailed, mechanical painting of such a diverse range of shapes has proven difficult. Water-transfer printing has been used for everything from car dashboards to press-on nails, but the technique falls short when trying to combine "complex shapes" with more detailed paintings. Previously, it was unpredictable how the paid would distort around complex shapes. A new technique for water-transfer printing has been created by a team of researchers from Zheijiang University in China. From knick knacks to 3D-printed leopards and tiger masks, detailed painting of complex objects can now be achieved through water transfers.
