技術說明

本發明提供一種形成連續性三維結構的噴墨方法。在一基板上形成一具有預先定義圖案之暫時結構。暫時結構與基板形成容置空間。噴塗墨滴於此容置空間，並令墨滴同時覆蓋接觸暫時結構表面及基板表面。藉由墨滴自身重力、墨滴與暫時結構間表面張力合力及墨滴與基板間表面張力合力三者之交互作用，令墨滴形成自我導流而能依預先定義之圖案填滿容置空間。墨滴固化後，移除暫時結構而留下墨滴之固化體，形成連續性三維結構。藉由暫時結構的調整，可控制連續性三維結構的幾何型態。從而解決了傳統噴墨方法無法有效縮短墨滴固化體線寬的缺點。 A method of forming a continuous three-dimensional structure by inkjet printing process is disclosed. A pre-patterned temporary structure is formed on a substrate. A space is formed between the temporary structure and the substrate. Ink droplets are filled into the space by inkjet printing process. Ink droplets cover the space and contact the surface of the temporary structure and the substrate. A self-aligned mechanism is formed by an interaction of the gravity of ink droplet, the surface tension between the ink droplet and the temporary structure, and the surface tension between the ink droplet and the substrate. The ink droplets fulfill the space by the self-aligned mechanism. When the ink droplet is solidified, a standalone continuous three-dimensional structure is formed by removing the temporary structure. The geometry of the continuous three-dimensional structure can be defined by the temporary structure; therefore a small track width can be obtained.
