CNC Accumulation
摘要
In this process, a substrate is immersed in photopolymer, and a part is fabricated inside the liquid. To start curing the liquid from the substrate, a light beam needs to reach the substrate without solidifying the liquid on the way. It is possible if the beam is guided through an optical fiber. The beam will then solidify the liquid between the fiber tip and the substrate, which gets attached to the substrate and the fiber tip. Teflon film on the tip is used to decrease the adhesion between the solidified material and the tip, causing the material to attach solely to the substrate. An increment in the attached material happens as per the requirement rather than as per the pre-set layerwise values, thus making the process additive layerless manufacturing.
