A US startup has developed a new 3D printing technology that uses light and oxygen to print solid objects at speeds 25 to 100 times faster than current technology.
The 3D printing technology developed by Silicon Valley startup, Carbon3D Inc, enables objects to rise from a liquid media continuously rather than being built layer by layer as they have been for the past 25 years, representing a fundamentally new approach to 3D printing, researchers said.
The technology allows ready-to-use products to be made 25 to 100 times faster than other methods and creates previously unachievable geometries that open opportunities for innovation not only in health care and medicine, but also in other major industries such as automotive and aviation.
The technology, called Continuous Liquid Interface Production (CLIP) manipulates light and oxygen to fuse objects in liquid media, creating the first 3D printing process that uses tunable photochemistry instead of the layer-by-layer approach that has defined the technology for decades.
It works by projecting beams of light through an oxygen-permeable window into a liquid resin.Working in tandem, light and oxygen control the solidification of the resin, creating commercially viable objects that can have feature sizes below 20 microns, or less than one-quarter of the width of a piece of paper.
