Variable Seriality: Surfaces and Additive Manufacturing as Design Research

Abstract

This paper investigates the role of variable seriality in the design of modular surfaces produced
through additive manufacturing, interpreting the surface as a project-based system rather than
a finishing element. The aim is to explore how modular repetition, combined with controlled
variation of morphological and production parameters, can generate surface configurations
capable of producing differentiated spatial and perceptual effects. The study adopts a design
research methodology, integrating parametric digital design, additive manufacturing, and
critical observation of prototypes. The experimentation resulted in a repertoire of modular
surfaces developed through systematic variations in geometry, depth, and density. The results
show how additive manufacturing enables strong continuity between digital models and
physical artifacts, transforming seriality into an open design strategy. The paper proposes
modular surfaces as flexible systems for the built environment, contributing to the debate on
architecture and technology by reinforcing design as a knowledge-producing practice.
