Question 1

What is the exposure for anycubic photon mono 4k i do not find in the guide

Accepted Answer

I use the anycubic photon mono 4k printer.   I use 5 to 7 second exposure setting.  Going to faster times such as 2-3 seconds has never worked.      Going to longer times don't look needed  This stuff works great. Sticks to plate every time. . I'm not in a hurry as this is for castings.  Make sure you have at least enough lift to break contact area. At least 6 mm.  Lift speed is kind of slow at 50 mm per minute. I want to give it time to break the seal between the part and bottom .  I use 30 seconds per layer on base plate to start.   With about 7 layers or so. This will make the base plate layers harder. Less time may soften it up and help get it off easy.  But not stick as well.    I clean tank every print and make sure no junk is hidden somewhere.  I level every print and use only clean resin. This stuff is the best  for castings.  Seems like curing takes many times longer under UV light.    But I look at each one and decide.  I lightly sand each model 100% . This will also help the coating material stick better.   REX

Question 3

what is the shelf life of Siraya Tech Cast?

Accepted Answer

If unopened does not really have one, I use 3 year old resins.
With open bottles of castable resins it is recommended to use fairly quickly as air/moisture can effect burnout. 
To keep cast fresh I pour some into another UV blocking bottle (amber glass) and use, this way it reduces how much air/moisture can affect the bulk of the resin.

Question 4

is this resin compatible with the new elegoo mars 3 msla 4k printer? If so what are the recommended settings.

It is best to cast as soon as you finalize full post curing. moisture in air can affect burnout
