3ders.org – New Design Tool ‘Printone’ Lets You 3D Print Wind Instruments in Crazy Shapes
Dec 6 2016 | By Tess
Earlier this year, we were impressed with a manufacturer’s ability to create a ocarina wind instrument using pretty much only a 3Doodler 3D pen. Although the instrument is beautiful and can be personalized in its setting, the creation process requires patience and time. If you are interested in making your own wind instrument but are missing the aforementioned factors, there is a new software tool that might be right for you. “Print aâIs a new interactive design tool that essentially allows users to create their own 3D printable wind instruments in virtually any shape or form. The tool, which uses interactive sound simulation feedback, can help create a wide range of 3D printed wind instruments.
Printone was developed by a joint team of researchers from Autodesk and Dartmouth College. The research project, which will soon be presented at the 9th ACM SIGGRAPH Conference and Exhibition on Computer Graphics and Interactive Techniques in Asia, shows how the team was able to create 16 star-shaped free-form wind instruments, from rabbit, dragon. , a snowman, and more. Each portable 3D printed instrument is capable of playing a simple melody inspired by its shape.
Wind instruments, which produce sound when the musician blows air in and through, can be complicated to make by hand. As the researchers explain, âThe sound of a wind instrument is governed by the acoustic resonance resulting from complex interactions between sound waves and the internal geometries of the instrument. So, creating an original free-form wind instrument by manual methods is a difficult problem. This is why most of the existing wind instruments have fairly conservative constructions – think of the tubular cylindrical shape of the recorder or flute.
Now, however, thanks to the rather neat Printone tool, users can create a huge range of wind instrument shapes. To use the tool, users need to upload a 3D shape to the tool, which automatically generates a hollow acoustic cavity inside. From there, the user can choose which notes they wish to include in the instrument (the four notes for playing Twinkle Twinkle Little Star, for example), and the location of the mouthpiece.
Printone also allows the user to choose the scale of the object, which in turn affects the range of notes that can be played. Throughout the design process, sound simulation allows the user to keep track of the sounds played by the instrument. For those less inclined to music, the tool also has an “AutoTune” feature that automatically sizes and places holes on the object. Once completed, the custom wind instrument can then be simply 3D printed on a desktop 3D printer.
â3D printing has opened up possibilities for personal customization in manufacturing,â commented Emily Whiting, study co-author, assistant professor of computer science at Dartmouth College and avid flautist. âOur research shows how it is possible to customize shapes not just for their appearance. , but also for physical behavior such as acoustics. We are also excited about the creative opportunities to design an instrument for a specific piece of music. Future work could extend to ergonomics so that the instrument’s finger configurations are easier to play for a particular melody. “
Of course, Printone will not replace traditional wind instrument making, but rather is intended to be used as a tool to create more playful and toy-quality instruments. For example, if you’ve always wanted to play Mary Had a Little Lamb with a Sheep, or Beethoven’s Ninth from the Composer’s Bust, Printone offers an easy 3D printable solution.
