Due to fluctuations in cooling or curing circumstances, totally different prints of the identical part are also prone to slight variations, which places limitations on consistency and repeatability. The open-source RepRap Project (for ‘Replicated Rapid Prototyper’) launched with the goal of creating self-replicating 3D printers CNC machining capable of printing their own parts, inflicting popular curiosity within the know-how to skyrocket. DLP or Digital Light Processing refers to a technique of printing that makes use of light and photosensitive polymers. While it is rather similar to SLA, vital thing} difference is the light source.
