Özet:

 Nasal dilators are medical devices used to relieve respiratory distress caused by structural anomalies in the nasal valve. These devices, which are applied to the nose externally or internally, widen the nasal valve part of the nose, reducing the air resistance and facilitating breathing. The structure of the nose varies from person to person, and there are even structural differences between two nasal valve structures of the same individual. Therefore, customized nasal dilators can be more efficient and comfortable. In this study, the design and fabrication of custom nasal dilators using reverse engineering and additive manufacturing methods are discussed. In the design process, the impression of the nasal valve was taken with a clay mold and the 3D model of this mold was obtained by photogrammetry method. The final model was then designed with a 3D modeling software to provide air passage and facilitate the use of the device. TPU was chosen as the material for the comfortable use of the nasal dilator due to its flexible feature. Then the final model was fabricated with an FDM Fused Deposition Modeling 3D printer. The final product was compared with its 3D model in terms of dimensional accuracy. As a result of measurements taken from various references, the average dimensional error in the product was obtained as 0.609 with 0.058mm. It is understood that the personalized nasal dilators proposed in this study can provide a great advantage over standard nasal dilators of the same form used for different nasal structures, thanks to their compatibility with the nasal structure of each user. Reverse engineering, which facilitates the modeling of free-form organic objects, and 3D printing technology, which enables direct fabrication from design, offers significant benefits for the design and production of personalized medical devices that are not suitable for mass production, without production line and high initial investment costs.

 Nazal dilatörler nazal valfdeki yapısal anomalilerden kaynaklanan solunum güçlüğünü gidermek amacıyla kullanılan medikal cihazlardır. Buruna dışarıdan veya içeriden uygulanan cihazlar burnun nazal valf bölgesini genişleterek buradaki hava direncini azaltır ve nefes almayı kolaylaştırırlar. Burun yapısı kişiden kişiye değişmekte hatta aynı bireyin iki nazal valf yapısı arasında bile yapısal farklılıklar bulunmaktadır. Bu nedenle kişiye özel olarak tasarlanan nazal dilatörler daha verimli ve konforlu olabilirler. Bu çalışmada tersine mühendislik ve eklemeli imalat yöntemleri kullanılarak kişiye özel nazal dilatör tasarımı ve üretiminden bahsedilmektedir. Tasarım sürecinde nazal valfin izi kil kalıp ile alınmış ve bu kalıbın 3B modeli fotogrametri yöntemiyle elde edilmiştir. Elde edilen model daha sonra bir 3B modelleme yazılımı ile hava geçişini sağlayacak ve cihazın kullanımı kolaylaştıracak şekilde tasarlanmıştır. Nazal dilatörün konforlu kullanımı için malzeme olarak esnek özelliğinden dolayı TPU seçilmiştir. Daha sonra modelin üretimi bir FDM Fused Deposition Modeling 3B yazıcı ile yapılmıştır. Elde edilen ürün, 3B modeli ile boyutsal doğruluk açısından karşılaştırılmıştır. Belirlenen çeşitli referanslardan alınan ölçümler neticesinde üründe ortalama boyutsal hata 0,058mm ile 0,609 olarak elde edilmiştir. Bu çalışmada geliştirilmiş olan kişiye özel nazal dilatörlerin her bir kullanıcının burun yapısıyla uyumu sayesinde farklı burun yapıları için kullanılan aynı formdaki standart nazal dilatörlere göre büyük üstünlük sağlayabileceği anlaşılmaktadır. Serbest-formlu organik objelerin modellenmesini kolaylaştıran tersine mühendislik ve tasarımdan doğrudan üretime imkân veren 3B baskı teknolojisi hat kurulumu ve yüksek ilk yatırım maliyetleri olmadan, seri üretime uygun olmayan kişiye özel medikal cihazların tasarım ve üretimi için önemli faydalar sunmaktadır.
