Rapid prototyping is closely related to 3D printers (additive manufacturing). Rapid prototyping is a technique for making a prototype model from a CAD file which is the final result, while a 3D printer is one of the processes. The 3D printer process is by melting the filament layer by layer to form a component or product. The 3D printer melting process uses a heater on the nozzle. This study aims to analyze the effect of nozzle diameter and layer thickness on the accuracy (dimensional measurement) of 3D printer objects. To determine the precision, a test object was made based on ASTM D995-08. The variation of nozzle diameter used is 0.2 mm and 0.5 mm, while the variation in layer thickness is 0.1 mm and 0.3 mm. In this study, delta type 3D printing was used with polylactic acid (PLA) material to make test objects. Dimension measurement using ASTM D5947-06. Analysis of the measurement results used ANOVA with a 2-level factorial design type and a 2 factorial interaction (2FI) model design using Design-Expert®. software. From the actual measurement results, the most accurate (precise) results are obtained on the test object with a variation of the nozzle parameters with a diameter of 0.2 mm and a layer thickness of 0.1 mm. From the analysis of the specimen measurement data, it can be concluded that the nozzle diameter significantly affects the response of length, width and height while the thickness of the layer affects the response of the length and width of the specimen.

Face shield is one of the important PPE (Personal Protective Equipment) for health workers in health services in the era of the COVID-19 pandemic as it is today. The limited number of face shield will certainly hamper the health services provided by the hospital. This Community Services activity was carried out at RSI Sultan Agung and RSIGM Sultan Agung to provide training on making face shield independently and also maintenance, so that face shield is more durable and not easily damaged. The tool used is a 3D printer which is easy to operate. 3D Printing technology will produce solid objects, and not like printing a sheet of paper on a printer that is commonly used. Design 3D models using CAD software. This activity was attended by 80 participants. 91.25% of participants are interested in making their own face shields as an effort to meet the need for face shields From the Community Services activities, around 100 face shields were produced which were handed over to the hospital.

“…Kuttig, et al [14] membuat prototype maxillofacial dari bahan PVA dengan menggunakan mesin 3DP. Mereka menyatakan bahwa modulus kelenturan produk dipengaruhi oleh arah orientasi printing dimana nilai kelenturan tertinggi terdapat pada variasi arah print X diikuti dengan arah Y dan Z. Penelitian lain menyampaikan bahwa keakuratan dimensi produk dari bahan polimer fleksible Eflex diameter 1,75 mm utamanya dipengaruhi secara berturutturut oleh flow rate, layer thickness dan nozle temperature [15].…”

Polyvinylalcohol (PVA) is a polymer that is often used in 3D printing technology in the health sector. However, most research addresses the behavior of products interacting with the body, and very rare information discus about the mechanical properties of 3DP products from PVA. This study aims to determine the effect of 3D printing process parameters on PVA materials using the Taguchi method. PVA filament with diameter of 1.75 mm was obtained from ESun Co. Specimen was designed with CAD according to ASTM D-638 Type IV and fabricated using Pursa-I3 3D Printer Machine. The orthogonal arrays L4 (2 2 ) experimental design with two process parameters namely nozzle temperature and extrusion width and two levels for each parameter with tensile strength in response was carried out. The specimen was then measured by weight, dimensions, and time of production. After that the specimens were tested using the Zwick Roell Z020 engine. The data were then analyzed using S/N Ratio and ANOVA. The results showed that all the products meet the dimensions that have been set with the product weight that is not much different (0.03-0.1 gr). S/N Ratio and ANOVA analysis showed the same results that the extrusion width parameter had a greater effect than the temperature of the nozzle on the tensile strength response of the PVA product. The combination of optimal process parameter levels obtained, nozzle temperature of 180 ° C and extrusion width of 0.4 mm produces the highest tensile strength of PVA products (7,611 MPa).
