Due to the nature of the process with respect to stereo lithography, there is a need for supporting structures for a number of parts, particularly the ones with undercuts or overhangs. There will be a need for manually removing these structures (Ball 2013). With respect to the other post steps of processing, a number of objects for 3D printing by the use of stereo lithography, there will be a need for certain cleaning and curing. Curing is known to be subjected to the part for intensified light within the machine like over for fully hardening the resin. There is general acceptance for this process as being the most appropriate processes of 3D printing with perfect finishing of surface.
Processing of Digital Light
Also known as DLP, this is known to be a similar process with respect to the previously discussed process as it is known to be a process working with the use of photopolymers. However, the main difference is known to be the source of light (Bowyer 2011). This is known to be using light source that is more conventional like an arc lamp, with a panel of liquid crystal display or a device of deformable mirror. The application of this can be done to the whole surface over the vat present on photopolymer resin within a particular pass, generally that helps to make it fast in comparison with stereo lithography. Further ahead, it is obvious that there is a possibility for producing very intricate and detailed objects, often in alignment with built- in functions and such that the need to assemble can be negated.
Also, it has been identified that this process of DLP is known to be producing extremely appropriate parts having perfect resolution, but the similar contexts are known to be including the similar requirements for the structure of support as well as post curing (Beckhusen 2013).
