The Making of Undesignable Textural Effects

The paper describes series of experiments directed towards devising methodology on utilizing 3D printer as generative tool in design process. A method to manipulate G-code, as an interface between digital parametric design and digital manufacturing, was developed in order to instigate emergence of textural patterning directly produced by fabrication process. Fundamental approach of the research is formed by such principles of “digital craft” as continuity between design and production through translation of algorithmic logic from stage to stage, integral involvement of an architect in all aspects of actualization and an element of “risk”, for the ability to modify production parameters converts space of making into space of discovery that is resistant to totalizing control.
In order to achieve surface texturization a manufacturing process was designed in which surface was informed by printing parameters, such as speed of material deposition, tool path and disabled retraction and actualized in a material medium of plastic. A range of techniques to add or subtract mass from a surface was programmed in G-code, allowing for iterative process and a range of effects to materialize. They are made, but not pre-determined, therefore these effects present a field of pattern heterogeneity and unexpected deviation. The success is evaluated on effect’s replicability, minute variation and range of effectiveness. Although trial and error process encourages spontaneous variation research strives to develop a rigorous system of interdependencies and causalities within the medium of digital fabrication based on thorough understanding of its affordances and constraints.
The value of presented experimentation is seen in potential contribution to discourse and practice of digital craft as it outlines a method to induce manufacturing machine to act as a “making hand” in the design process.
