The Advantages from SLA are clear. Prints come out much smoother and the visible layer lines are at a very minimum. Most parts can immediately be used and painted without much sanding. Small details like the text on the back are more profound and clear. The laser size is 0.085mm compared to the 0.4mm nozzle size of a FDM printer making it able to recreate very small details. The parts of SLA rival much more expensive industrial solutions.
The Similarities between FDM and SLA are that in both systems layers can not be printed in thin air. If your part has an overhang it will need to be supported in either system for the model to be correctly built. So both technologies use support structure to support the model and overhangs during the print. These supports will need to be removed after printing.
The Disadvantages from SLA are that it is more expensive than FDM (Although still much cheaper than industrial solutions). In FDM only material is driving the costs and the occasional nozzle replacement. In SLA the material is about twice as expensive and the build tray is a part that will need replacement after a number of prints. The prints from SLA will also need to be cleaned after printing which uses up time and cleaning resolution.
