• SLA allows rapid production of accurate scale models of design projects in a short time. ( Typically within a day or two )
• The prototype model is lightweight and durable, with the strength of polystyrene plastic.
• The prototype can be mounted and drilled, like in the actual situations with the real product.
• The process is simple for the user because there isn't much input needed from a human besides the STL file. The computer does everything else. There is no milling or masking needed.
• The process can help to catch design errors before the objects goes into mass production thus potentially saving money for companies because there is three-dimensional visualizations of product design.
• The process allows companies to be able to sell their products more effectively with a prototype model.
  

• Uncured material in the SLA process can be toxic therefore there must be proper ventilation and disposal of toxic materials.
• The parts made using the SLA process can be brittle so there cannot be too much stress applied to the part.
• The surface tends to be a little tacky so it's difficult to design good looking products using this process.
• Long-term curing can lead to warping
