They might as well start making their tissues functional, and, bit by bit, build towards synthetic humans that can be used as very lifelike robots. Or why not grow actual organs and put them in?
The need for all the support "machinery"? Lymphatic system to dispose of waste, vascular system to pipe food and oxygen, oxygenation for the blood, glucose production, hydration, temperature regulation... These are hard to implement because the scale from the macro to the micro - from inches in diameter to microns.
What about the intricate cellular dynamics of tissue growth? Wouldn't the "proprietary formula of salt, water, and fibers" fail to replicate a set of some [at least observable] macroscopic effects, thus limiting the overall experience deepness for the practioner?

I wonder if they could at least sell components. The artificial skin in particular sounds like it could be worthwhile on its own, though maintenance could be tricky.
This sounds like a fun place to work
