3D inkjet-printing of photo-crosslinkable resins for microlens fabrication

The demand for optical components such as microlenses has been growing at a rapid rate in recent years. While conventional methods manufacturing these are well known, they often time-consuming, detrimental the environment and unable to keep up with increasing demand. To overcome issues, technique of three-dimensional (3D) inkjet printing attracted much attention. aim this review was investigate 3D process fabrication identify key methodologies which can be used control properties resultant microlenses. Inkjet identified viable alternative production owing its high flexibility, scalability efficiency ability produce good quality products. Substrate modification shown method by geometric controlled.
