I believe the problem is warping rather than shrinking. A Mech Eng PhD friend of mine worked on algorithms to compensate for it.
However, going by the Shapeways support forum it’s mainly a problem with large and thin parts.

For metal printing the workflow is proprietary - the "slicing" software is machine specific and the powder characteristics are controlled so shrinkage is accounted for in the machine.
A different story with steel printing apparently https://imaterialise.helpjuice.com/design-printing/shrinkage

@sohi
Is there any shrinkage with printed metal like there is with plastics?
