Based on 2D digital fast and precision inkjet wide-format printing technology and page wide print head technology, we have developed a novel micro 3D stereo digital printing or 3D object accurate and fast production. By using UV curable inkjet technology or IR curable inkjet technology, we can easily and fast solidify the true colorful 3D objects and bring 2D digital technology up to 3D digital printing level. Two types of 3D printers will be addressed to show micro-3D inkjet technology including their various applications on textile, fashion, ceramics, leather, plastics, glass, packaging, personal decorations, detailed stereo sculpture, dental, spine, biotech application, etc..
