Abstract
A method of residual ink removal in an ink-dependent 3-D printing process includes pre-heating a build block to an evaporation temperature. This is preferably done after stacking and before compression. Later compression will then involve a higher temperature to allow fusing of thermoplastic material in the build block, but without residual ink.
