Novel Extruder Heat Block Designs to Improve the Thermal Efficiency of 3D Printers

Öz

3D printers are the most common and popular method of additive manufacturing technology and provide fusion of materials using thermal effects. This phenomenon makes that temperature the most important factor affecting printing quality. The temperature is provided by the Aluminium Extruder Heat Block in the extruder and the temperature regime must be constant according to the type of printing material. The objective of this study is to make aluminium Extruder Heat Block designs with high thermal efficiency to keep the temperature regime constant and to analyse the thermal behaviour of new designs with a commercial product block design using ANSYS simulation. The materials of the blocks were chosen the same and the temperature distribution of the blocks and the average heat flux were calculated by determining the boundary conditions. The results obtained from the simulation are satisfactory when compared with the thermal behaviour of a commercial product block.

3D Yazıcıların Termal Verimliliğini Artırmak için Yeni Ekstrüder Isı Bloğu Tasarımları

Öz

3 boyutlu yazıcılar eklemeli imalat teknolojisinin en yaygın ve popular methodudur ve termal etkileri kullanarak malzemelerin füzyonunu sağlarlar. Bu fenomen sıcaklığı baskı kalitesini etkileyen en önemli faktör haline getirir. Sıcaklık ektrüderdeki alüminyum ekstrüder ısı bloğu tarafından sağlanır ve sıcaklık rejimi baskı malzemesinin tipine göre sabit olmalıdır. Bu çalışmanın amacı, sıcaklık rejimini sabit tutmak için ısıl verimi yüksek alüminyum ekstrüder ısı bloğu tasarımları yapmak ve yeni tasarımların ısıl davranışını ANSYS simülasyonu kullanarak ticari bir ürün bloğu tasarımı ile analiz etmektir. Blokların malzemeleri aynı seçilmiş ve sınır koşulları belirlenerek blokların sıcaklık dağılımı ve ortalama ısı akısı hesaplanmıştır. Simülasyondan elde edilen sonuçlar, ticari bir ürün bloğunun termal davranışı ile karşılaştırıldığında tatmin edicidir.
