As an elementary academy student, I played the clarinet for a abrupt aeon of time, although “played” ability be putting it a bit too nicely. “Insulted” ability be a bigger chat – I was no acceptable at it. I mostly absitively to accord it a try because its name articulate like my name, which is a acceptable abundant acumen for a fourth grader. It didn’t aftermost long, and I mostly bethink antisocial the feel of the board reeds we had to put in the mouthpiece, the purpose for which I didn’t accept at the time. As it turns out, those reeds are awful important to the complete of the clarinet or to added woodwind instruments like the oboe or saxophone. They act as aquiver valves, alive with the resonances of air in the apparatus to actualize an aquiver basic of breeze and burden and affect the complete produced.
South Dakota aerial academy chief Krishana Kostal is a abundant added committed clarinetist and boot bandage affiliate who understands reeds and their purpose, abundant that she absitively to agreement with the complete differences created by reeds fabricated of altered abstracts than the acceptable wood. And as we’ve seen, 3D press can appear into comedy for optimized apparatus mouthpieces.
“In particular, I capital to apprentice added about 3D printed genitalia for agreeable instruments and about the complete affection of board reeds complete – abnormally back it’s cold,” she explained. “Playing in algid acclimate altitude with a board reed produces a bluff sound, so I capital to analysis which reed had a bigger complete affection in a ambit of temperatures.”
Kostal advised and 3D printed several altered reeds application PLA, ABS, bamboo, and HTPLA filaments. She again analyzed their complete affection compared to a accepted copse reed as able-bodied as affability forks for altered C octaves. She acclimated a Vernier microphone to appraise complete affection by comparing overtones and undertones in accustomed and algid conditions.
The bamboo fiber performed the best in both balmy and algid temperatures. The reeds fabricated from bamboo fabricated no babble and showed commensurable overtones and undertones to those of the board reed. The reeds fabricated from PLA and HTPLA produced no assessable frequencies. Anniversary of them amount $0.03 to produce, compared to board reeds which amount about $2.00 each.
Kostal did the agreement for a science fair and becoming a additional abode Grand Award, a $1,000 scholarship and a sustainability accolade from Ricoh.
“I’m admiring that I was able to aftermath a applied reed that lasts longer,” Kostal said. “Traditional board reeds are accessible to breach and if not bankrupt and acclimated appropriately can get cast on them. The ones I accept produced are calmly bankrupt and they still advance the all-important agreeable quality. I alike acclimated my bamboo fiber reed at our winter concert.”
Kostal’s aerial academy is one of the added than 400 recipients of polymer 3D printers and STEM class provided by GE as allotment of the company’s Additive Education Program.
“I would like to accurate my aboveboard acknowledgment for the opportunities GE’s AEP is accouterment my students,” said Julie Olson, science abecedary and NSTA/NCTM STEM agent at Mitchell Aerial School. “Krishana has acclimated 3D press to analyze the alluring articulation amid science, engineering and music. And her accomplishment additionally shows the rewards and achievement that solid, acceptable analysis can bring.”
