That might work. The reason I was thinking ultrasonic was other sla printers print a layer, then the object moves down and up before the next layer is printed. I was guessing that this is to insure the model is coated, and break any surface tension. Ultrasonic would keep a constant ripple at a high frequency where the average wave would be the print area.

However, I like your idea better. So much simpler!
