This project explores the relationship between 3D printing parameters and the roughness of a bio-circular material. Findings show how surface roughness is dependent on 3D printing parameter variations that influence the acoustic properties of the material.
The bio-circular material
Controlling roughness explores the potential of bio-circular materials for architectural applications, focusing on their use in fabricating interior walls.
The project implements a material recipe by the studio Omlab. With this material, the project investigates how 3D printing can be leveraged to actively design and control material properties, to enhance the unique opportunities of the material.
Experimentation
Through a series of experiments, findings demonstrate that surface roughness is influenced by modifying 3D printing parameters. This finding led to the exploration of the relationship between surface roughness and acoustic performance.
By measuring the absorption coefficients of different specimens, it was revealed that 3D printing parameters can be modified to influence the material’s acoustic properties.
Controlling roughness
As an outcome, Controlling Roughness proposes a set of blocks produced with the bio-circular material. These blocks show a contrast in acoustic absorption from none to very pronounced parameter variations.
Controlling roughness shows that additive manufacturing enables the design of multi-scale surface roughness that influences acoustic performance. This opens new pathways for 3D printing with bio-circular materials in architectural contexts. Positioning roughness as an asset controlled to meet architectural needs.
