Acoustic scale modelling continues to be an important tool in auditorium design, however the main obstacle to its use is the difficulty, time and cost associated with creating suitably accurate models. Additive manufacturing (AM), or 3D-printing, presents exciting new possibilities to reduce or even overcome these challenges. The acoustic properties of AM materials required investigation. A 1:10 scale reverberation chamber was constructed and two materials, ABS plastic and nylon, were tested to ISO 354. This paper reports the results of the experiments
