On one side, G-code generated by the translation of the slicer, “which tries to force the designated into invariant structure relations and to assimilate completely the designated into signified; on the other, expressive” 3D print” striving to open itself up to the space of vision and desire and to produce figural with the signified.” The former, with its precise, invariant rules of translation of the mathematical figure of a 3D model into a 3D print, functions as a perfectly closed system of generative grammar, translating 3D model, point for point, into a 3D print. By minimising translation errors, G-code assimilates the resulting print completely into signified, a 3D print of the given 3D model. The latter, emerging from the movement of the printer head, is the encounter of the melted plastic with the air and the layer beneath it. Only in this encounter does the 3D-model-G-code-3D-print representational machine start to break down. When the figural emerges, only then the excitement of the process begins. And the figural, until now contained within “invariant structure relations”, starts to warp, crack, bend, and tear the signified, with all of its transgressions catalogued in “3D Printing Failures”, a penalty book of crimes that the figural committed against the signified.
