Özet:

 This study investigates the effect of line-width values on the properties of 3D three dimensional printed PLA polylactic acid parts. 3D printing of parts was carried out by using low-cost cartesian type FFF fused filament fabrication desktop 3D printer. Brass nozzle with a diameter of 0.6 mm was used to print PLA parts. Parts having line-width values of 0.6 mm to 1.2 mm were printed and the effect of line-width values on the mechanical properties and printing time was investigated. Mechanical properties of 3D printed parts were determined by using tensile testing device ZwickRoell, Z250. Microstructures of 3D printed samples were investigated by using optical microscope Leica, DM 2500. Printing time for each part was recorded during 3D printing process. Surface profiles of parts were investigated by using surface roughness tester Mitutoyo SJ-210. Microstructural investigations showed that the voids were formed between adjacent deposited lines and the void content decreased from 5.89 to 5.13 with increasing line-width value up to 1.0 mm. Surface roughness parameter of Ra increased from 5.110.21 µm to 9.291.12 µm with increasing line-width. Tensile strength of 3D printed specimens showed a slight decrease with increasing line-width due to the presence of voids between adjacent u-turn sections. The tensile strength values were determined as 58.521.93 MPa and 46.541.18 MPa for specimens printed with line-width values of 0.6 mm and 1.2 mm respectively. SEM images of tensile fracture surface demonstrated that the main failure mechanism of the printed specimens was the rupture of deposited lines instead of fracture of inter-line bonding.

 Bu çalışma, hat-genişliği değerlerinin 3B üç boyutlu yazdırılmış PLA polilaktik asit parçalarının özellikleri üzerindeki etkisini incelemektedir. Parçaların 3B yazdırma, düşük maliyetli kartezyen tip FFF eriyik filament üretimi masaüstü 3B yazıcı kullanılarak gerçekleştirildi. PLA parçaları yazdırmak için 0,6 mm çapında pirinç nozul kullanıldı. 0,6 mm ile 1,2 mm arasında hat genişliği değerlerine sahip parçalar basıldı ve hat genişliği değerlerinin mekanik özellikler ve yazdırma süresi üzerindeki etkisi incelendi. 3B yazdırılmış parçaların mekanik özellikleri, çekme test cihazı ZwickRoell, Z250 kullanılarak belirlendi. 3B yazdırılmış numunelerin mikro yapıları optik mikroskop Leica, DM 2500 kullanılarak incelendi. 3D yazdırma işlemi sırasında her parça için yazdırma süresi kaydedildi. Parçaların yüzey profilleri yüzey pürüzlülük test cihazı Mitutoyo SJ-210 kullanılarak incelendi. Mikroyapısal incelemeler, boşlukların bitişik depozitlenmiş hatlar arasında oluştuğunu ve boşluk içeriğinin 1,0 mmye kadar artan hat genişliği değeriyle 5,89dan 5,13e düştüğünü gösterdi. Yüzey pürüzlülük parametresi Ra, artan hat genişliğiyle 5.110.21 µmden 9.291.12 µmye yükseldi. 3B yazdırılmış numunelerin çekme mukavemeti, bitişik u-dönüşü bölümleri arasındaki boşlukların varlığı nedeniyle artan hat genişliğiyle azalma gösterdi. Çekme mukavemeti değerleri, 0,6 mm ve 1,2 mm hat genişliği değerleriyle yazdırılmış numuneler için sırasıyla 58.521.93 MPa ve 46.541.18 MPa olarak belirlendi. Çekme kırılma yüzeyinin SEM görüntüleri, yazdırılmış numunelerin ana hasar mekanizmasının, hatlar arası bağların kırılması yerine depozitlenmiş hatların kopması olduğunu gösterdi.
