Exposure time can have great impact on dimensions as what we are doing here is producing partially cured (hence the need for final post-printing curing) stacks of tiny mushy blocks, with exposure time being the most controllable factor in how mushy they are. and how well they stick together..
With your observed error of just +0.77% (51.19/50.8) it won't take much to alter the final dimension.
The 10 micron layer height also add a "twist" as it means there are 5X as many layers (as compared to the 50 micron default for most SLA printing)--thus more opportunity for cumulative error. 10 microns is 0.00039", do you really need that precision?
50 micron = 0.00197"
