The bow is an integral part of the quality of a stringed instrument’s performance. While designs have varied over time, the technique for manufacturing them has remained very much the same. This isn’t just a case of trying to do something in a new way simply for novelty’s sake, however. Peppel was interested in working on creating 3D printed bows for environmental and economic reasons as well.
Bows can be purchased inexpensively–but you get what you pay for. The sound from a $100 bow might cause you to question your devotion to stringed instruments. For a nicer off-the-shelf bow, you’re looking to spend at least $200, and if you want one that is customized you’d be starting at around $5,000. Add that to the price of the instrument, the strings, the rosin, etc. and you’re starting to see a significant amount of your budget disappear.
The door to customization with a lowered environmental impact and a more affordable price tag is opened through the introduction of the 3D printed bow. As anyone who knows a musician will realize, though, none of that matters if the bow doesn’t live up to its traditionally produced counterpart. Peppel has had his bow tested by several very discerning violinists and it passes with flying colors.
“If it doesn’t sound the same, it’s too close for me to tell the difference,” Peppel says. “It may not be equal to a $5,000 bow yet, but it’s getting there. The real importance of the bow is giving the right amount of flex, and with the addition or removal of material, all of that can be controlled. “
In order to make the shift from traditional assembly to one based on additive manufacturing, Peppel had to explore material, form, and structure as well as work within some practical constraints. Check out more of his bow process in his portfolio.
“I wanted it to be easy to assemble and to fit on the smallest standard bed, 150 x 150mm. That took a lot of trial and error,” he said. “I had to spend a lot of time addressing the issue of warping. If it’s not straight when put together, then when it is tightened, it will wobble all over the place. That’s one of the reasons I ended up with a PLA plastic.”
Listen to the sound in the video and judge for yourself. I think it sounds like the future. Do you agree? Let us know how you think it sounds in the 3D Printed Bow forum thread at 3DPB.com.
