In the Printer Settings --> Exposure --> Minimum exposure time

However, I do not know if the 1s limit is set for a mechanical reason also (maybe to limit the go back and forth speed which could reduce the life of the machine, or to avoid vibrations). 

So it is possible to work it around, but maybe you will face some problems. 

Another alternative is reducing the layer thickness keeping the same time. The resolution will increase, but also the printing will take much longer.

Does anyone know a work around?

or is this a physical limit?

 

Thanks in advance for any help!
