Abstract

In this research, the potential of Titanium Additive Manufacturing as a fabrication technique for wind musical instruments was presented. The investigation was focused on wind musical instruments in general and the flute recorder specifically while evaluating the Yamaha polymer flute analog with the 3D printed titanium one. It was demonstrated that Ti-AM provides a promising and cost-efficient method for novel musical instrument production with unique sound properties.

The research is based on the following initial hypotheses:

         Titanium 3D-printing has the potential to become a common tool for product design in the near future, including that of musical instruments.

         Titanium Additive Manufacturing has potential for wind musical instrument production.

         Titanium Additive Manufacturing could enable geometrical optimization and design of new-shape wind instruments that could not be produced by other manufacturing techniques.

The main aim of the research is to evaluate the effectiveness of Titanium Additive Manufacturing for the design and production of wind musical instruments.

To achieve the aim several additional goals were formulated.

Goals for survey research:

         Defining potential applications of Ti-AM for Industrial design in the field of musical instruments

         To find what makes Titanium a promising material for the chosen application in comparison with other materials used for conventional wind instruments manufacturing.

         Clarifying the limitations of Titanium machining and manufacturing.

Goals for the case-study:

         Developing a design, fabrication and evaluation method of wind musical instruments by Ti-AM, such as the recorder flute

         Approving musical properties of 3D printed titanium instruments.

The current research found that Ti-AM could be utilized for the re-design of existing wind musical instruments, and even for designing new ones. Moreover, according to the performed literary survey and experimental findings, Titanium Additive Manufacturing has unique advantages for wind musical instruments.

The motivation of this work is to demonstrate the potential of Ti-AM for the design and manufacturing of new instruments, which can lead to new musical properties, shapes and artistic solutions for future instruments.

In this research Titanium Additive Manufacturing has been firstly used as a design method for wind musical instrument production. Besides, it could be considered as a first attempt to investigate musical properties of the printed titanium.

The case study Flute Recorder 3D design and Ti-AM were conducted. The results and comparison of the Titanium Printed Flute with the initial polymer analog and traditionally manufactured Titanium-made flutes are as follows.

There are the following benefits of Ti-Flute over polymer analog:

a.       Innovative. According to the musicians’ evaluations, the main attractive feature of the Ti-Flute was an innovative design.

b.      Higher Biocompatibility.

c.       The musical sound of the Ti-Flute, according to studio recording tests, is significantly richer, as the material does not absorb the sound waves as intensively as it does in the polymer-made flute.

d.      The lifetime of the Ti-Flute is higher, as titanium has a higher strength to sound waves impact.

e.       Hardness. Ti-Flute would withstand a drop test from 100cm.

f.        Easy design development:  the further design and development of the product by Ti-AM are much easier and low-cost than using traditional manufacturing.
