Abstract
Fused Deposition Modelling (FDM) banyak digunakan sebagai metode dalam pembuatan rapid prototyping dan salah satu yang dikembangkan adalah sepeda. Balance bike adalah jenis sepeda yang tidak menggunakan pedal. Balance bike bergerak dengan didorong menggunakan kaki sambil berlari atau berjalan. Salah satu bagian terpenting dalam sepeda yaitu ban. Namun, pada kenyataannya ban pneumatic memiliki kekurangan dalam permasalahan lingkungan. Pada penelitian ini, ban akan diproses dengan 3D printing dengan menggunakan filamen Thermoplastic polyurethane (TPU) pada pembuatannya. Dengan menganalisis beberapa variasi desain geometri ban yaitu honeycomb, tweel, diamond dan triangle. Dengan melakukan pengujian beban statis menggunakan software simulasi Ansys didapat bahwa ban airless dengan variasi honeycomb adalah yang terbaik dalam beberapa aspek yang dianalisis seperti equivalent stress sebesar 976.190 Pa, equivalent elastic strain sebesar 0.00043773 m/m, total deformation sebesar 0.000022627 m, kurva stress-strain terbaik dibandingkan desain lainnya, bobot real untuk skala banding 75% sebesar 410 gram, dan survey publik sebesar 32%. Sehingga ban ini layak dicetak dengan metode Fused Deposition Modelling (FDM).
===========================================================
Fused Deposition Modeling (FDM) is widely used as a method in making rapid prototyping and one that is developed is a bicycle. Balance bike is a type of bicycle that does not use a pedal. Balance bike moves by being pushed with legs while running or walking. One of the most important parts of a bicycle is a tire. However, in reality pneumatic tires have disadvantages in environmental problems. In this study, the tire will be processed with 3D printing using Thermoplastic polyurethane (TPU) filaments in its manufacture. By analyzing several variations of tire geometry designs, namely honeycomb, tweel, diamond and triangle. By testing static load using Ansys simulation software, it is found that airless tire with honeycomb variation is the best in several aspects analyzed such as equivalent stress of 976,190 Pa, equivalent elastic strain of 0,00043773 m / m, total deformation of 0.000022627 m, the best stress-strain curve compare to other design, real weight for scale of 75% by 410 grams, and public survey by 32%. So that this tire is worth printing with the Fused Deposition Modeling (FDM) method.
