I am printing the purple castable wax and was wondering if it is OK to sand it to get it smoother.

Hi andrewthomson,

That is a good question - I was informed that this should be fine, although there is a leaning preference towards using flush cutters, leaving a slight raised bump on the resin, and removing after casting to get the part more smoother. If you have any specific applications in mind, you can [create a support case with our support team](https://support.formlabs.com/s/contact-support?language=en_US) and they can look into this further for you.
