“…3. A schematic diagram of the methods of smoothing the surface of 3D-printed parts Certain 3D-printing filament materials, such as ABS could be treated with acetone vapors to reduce the roughness parameters [4]. However, that process is difficult to control, especially in thin-walled objects and it cannot be applied to treat polylactide (PLA), as this material requires more advanced chemical compounds [5].…”

The paper contains a study of the influence of thermal treatment of the 3D-printed polylactide parts in sodium chloride dust on the surface roughness of the manufactured part. The conducted experiment features annealing with the use of two different sizes of NaCl crystals and two levels of temperature. All the samples were made with natural polylactic acid filament using the fused deposition modeling (FDM) method. The samples were put into a salt scaffold and placed in the electric furnace to remelt the surface of the part while keeping pressure on the walls to prevent unwanted deformation. The results show that it is possible to improve the quality of additively manufactured component’s surfaces as long as optimal parameters are applied.

“…Mekanik yüzey işlemlerinin yanı sıra, aseton banyosuna daldırma, kimyasal buhar ile yüzeyi çözerek polimerik parçaların yüzey pürüzlükleri azaltılabilmektedir. Bu sayede tasarımın görsel prototipi elde edilmekte ve dış ortamlara karşı polimer malzemenin de korunması sağlanarak üretilen parçanın kullanım ömrü arttırılabilmektedir [20,21].…”

Eklemeli imalat geleneksel malzeme üretim tekniklerine göre sahip olduğu birçok avantaj nedeniyle son yıllarda hızlı bir şekilde yaygınlaşmaktadır. Bu avantajlardan bazıları, kalıba gerek kalmadan üretime izin vermesi, gerektiği kadar hammadde kullanılması, kişiye özgü ürün üretimi ve stok maliyetlerinin azaltılmasıdır. ISO/ASTM 52900 standardına göre yedi farklı eklemeli imalat teknolojisi mevcuttur. Eklemeli imalat teknolojilerinde metal, polimer, seramik ve mum olmak üzere bu yedi teknolojiye uygun olarak geliştirilmiş malzemeler kullanılabilmektedir. Polimer esaslı malzemeler söz konusu olduğunda malzeme ekstrüzyonu eklemeli imalat teknolojileri arasında en fazla kullanılandır. Malzeme ekstrüzyonu ticari olarak Fused Depositin Modelling (FDM)/Eriyik Yığma Modelleme (EYM) ve Fused Filament Fabrication (FFF) olarak adlandırılmaktadır. EYM teknolojisi başta hızlı prototipleme ve ürün geliştirme alanlarında olmak üzere, havacılık, otomotiv, beyaz eşya, tekstil, sağlık ve eğitim sektörlerinde yaygın olarak kullanılmaktadır. Özellikle ABS (Acrylonitrile Butadiene Styrene) ve PLA (Polylactic Acid) gibi polimer malzemelerin yanında PEKK (Polyetherketoneketone), PEI (Polyetherimide) ve PPSU (Polyphenylsulfone) gibi polimerlerin de kullanımına izin vermesi nedeniyle EYM teknolojisi üstün özelliklerin tercih edildiği endüstriyel alanlarda da kullanılabilmektedir. Bu çalışmada endüstride kullanımı hızla yaygınlaşmakta olan EYM teknolojisi ve uygulama alanları hakkında detaylı bilgiler verilmiştir.

“…This factor should be improved as surface irregularities promote bacterial adhesion and biofilm accumulation [54]. However, there are simple ways to reduce surface roughness for FDM-produced devices [55,56]. Finally, the resulting catheters showed gentamicin release over a period of up to five days.…”

Fused Deposition Modelling as a Potential Tool for Antimicrobial Dialysis Catheters Manufacturing: New Trends vs. Conventional Approaches

The rising rate of individuals with chronic kidney disease (CKD) and ineffective treatment methods for catheter-associated infections in dialysis patients has led to the need for a novel approach to the manufacturing of catheters. The current process requires moulding, which is time consuming, and coated catheters used currently increase the risk of bacterial resistance, toxicity, and added expense. Three-dimensional (3D) printing has gained a lot of attention in recent years and offers the opportunity to rapidly manufacture catheters, matched to patients through imaging and at a lower cost. Fused deposition modelling (FDM) in particular allows thermoplastic polymers to be printed into the desired devices from a model made using computer aided design (CAD). Limitations to FDM include the small range of thermoplastic polymers that are compatible with this form of printing and the high degradation temperature required for drugs to be extruded with the polymer. Hot-melt extrusion (HME) allows the potential for antimicrobial drugs to be added to the polymer to create catheters with antimicrobial activity, therefore being able to overcome the issue of increased rates of infection. This review will cover the area of dialysis and catheter-related infections, current manufacturing processes of catheters and methods to prevent infection, limitations of current processes of catheter manufacture, future directions into the manufacture of catheters, and how drugs can be incorporated into the polymers to help prevent infection.
