SLA Printing Pros – Accuracy, Design Flexibility is very good, Wide Range of resins standard, flexible, tough, castable high temp and many more, Final part can be use as actual assembly part in most cases
SLA Printing Cons – Print size is smaller, Material costs are higher, Production speed is slower.
FFF Printing Pros – Material costs low, Production speed is faster, Great for testing prototype parts at a lower cost
FFF Printing Cons – Weaknesses in samples, Accuracy may vary, Parts are great for testing but not to be used as production part
Both have their merits to advance engineering and design.
