“…Anderson proposed direct recycling of the applied PLA filament thru its floor up and reextrusion into 3D printing filament. After extrusion cycles and one 3D printing process, the cloth keeps comparable diameter and surface end because the authentic one, even as its mechanical homes exhibit mild deteriorations [7]. Unexpected discount in viscosity, attributed to chain scission at some stage in recycling, is the primary draw-lower back that prohibits subjection of the applied PLA filament to similarly 3D printing [8] As the main component of 3D printing materials are filaments that have been extracted from raw materials that can indeed be used as solid objects.…”

3D printing filament is the main asset in the development and manufacture of 3D objects. However, not all filament materials can be made easily. The difficulty level of 3D printing lies in the materials that are not commonly used. ABS and PLA are the easiest filaments to use, currently we are researching 3D printing filaments made from recycled disposable mask where machine specs are needed to enable 3D object fabrication. Recycled Disposable masks becomes an important research object when mask waste is widely used during the Covid-19 pandemic and currently it can be an alternative when these materials can be recycled into 3D printing filament. In this research also requires techniques to analyze typical filament materials that are adjusted for ambient temperature, filament thickness, nozzle temperature, and print bed temperature. In the design process, it is also necessary to set printing quality standards on the software used, such as the configuration of the raft printing support, the enable of the retraction. This study also analyzes the results of different objects for each filament diameter, filaments smaller than 1.75 mm will have a high vacancy rate on the object, while filament diameters with sizes larger than 1.75 mm will have high vacancy rates on the object. difficulties when entering the filament into the head print on 3D printing machine. It is also hoped that in this research, the 3D printing objects can be printed correctly and can be used as a reference to determine which is better than other filament material schemes and adjustments to different techniques.

“…A layer height of 0.14 mm shows the optimum value for increasing printing speed, and obtaining the appropriate product [9]. Previous study has also investigated the influence of deposition layer to surface quality for self-supporting deposit layer [10]. It shows that the angle 11 o can improve the quality of 3D printed surface.…”

In 3rd revolution industry, additive manufacturing has a role in term manufacturing process for creating a part. Additive manufacturing has popular name that is called 3D printing technology. The surface quality of 3D printed part is still observed and developed. So, the purpose of research is to know the surface quality of 3D printed part to different layer height and orientation of deposit layer in Polylactic Acid material (PLA). The experimental test involved a 3D printer machine to build square 3D printed part. Furthermore, the quality surface of specimen is measured by using SurftestSJ-301 Mitutoyo device. The layer height of the test specimen is varied from 0.05 mm to 0.15 mm with the increment of 0.5 mm for each specimen. The layer angle of deposit material is also varied from 45o to 90o with the increment of 15o for each variation. Base on the observation and analyzation, the highest roughness is on the Lh 0.15 mm (11.79 ) with 45o of layer angle of deposit material, whereas the lowest roughness on the Lh 0.05 mm (0.98 ) with 90o of layer angle of deposit material.

“…Previous research showed that a layer height of 0.2 mm showed a relatively low manufacturing time compared to a layer height of 0.15 mm [7], whereas at a layer height of 0.25 mm, the difference in print time was not significant. Apart from that, the vertical orientation of the workpiece print could also slow down the print time [8]. To speed up printing time, low infill density could be used to make printing time efficient, but it could reduce the mechanical properties of the printed product [10].…”

Manufacturing time and energy consumption are two important parameters to evaluate the manufacturing process. The main purpose of this study was to analyze the energy consumption and printing time of 3D printed part between hollow and without any hollow structure. The specimen models were designed according to ASTM D368-IV standards and printed using a 3D printer device. During the printing process, the wall thickness of specimen was varied into three different types, 0.4 mm; 0.8 mm and 0.12 mm. Furthermore, the cavity was filled by polymer resin as main material for strengthening the specimen. Time and energy consumption of manufacturing process was recorded. In addition, the strength of specimens was observed using universal tensile test machine. The results showed that the highest manufacturing speed was occurred on the specimen that had wall thickness of 0.4 mm. Besides that, its parameter had a lowest energy consumption than specimen that had wall thickness 0.12 mm. The wall thickness showed the significant parameter to reduce the energy consumption, printing speed and material usage..
