NOTE:
The default settings are derived experimentally with resin produced by 3D Ink™,

Step resolution should be kept between 30 and 60 microns for best results but can be set
between 5 and 100 microns.
LED current should never be set above 35, and should only be set at 35 when the 420 nm
LED is placed on a metal core PCB.
Exposure time will be driven by a combination of layer thickness and LED current.
Resin settling time is the amount of time required for the resin's surface to return to level
after the build platform has moved.
