PENGARUH PENAMBAHAN SISTEM IOT RASPBERRY PI TERHADAP KECEPATAN CETAK DAN TINGKAT PRODUKTIVITAS OPERATOR 3D PRINTER REPRAP

Abstract

Most of desktop-scale 3D printers are based on the open-source design of the Replicating
Rapid Prototyper (REPRAP) community. One aspect that can be developed in REPRAP 3D
printers is the addition of Internet of Things (IoT) technology. Therefore, a Raspberry Pi-based IoT
system that can be implemented on a REPRAP 3D printer is developed. The IoT system allows
the 3D Printer to connect into internet network and has a website-based interface. This study aims
to compare the impact of Raspberry Pi based IoT systems implementation on the 3D printing
speed and to measure productivity level of 3D printer operator. Testing is done by printing four
objects when the IoT system has not been added to the 3D printer and printing four objects when
the IoT system has been added to the 3D printer. In testing, the data on the printing time of each
object is obtained, this data is used to compare the print speed between before and after the 3D
printer was added to the IoT system. Furthermore from testing, the data of time required by
operators to prepare and monitor the performance of 3D printers is also obtained, this data is used
to compare the productivity levels of 3D printer operators before and after adding the IoT system.
Based on the test results, it was found that 3D printers with IoT systems have faster print
preparation times than 3D printers without IoT systems. However, 3D printers with IoT systems
have a longer machine time than 3D printers without IoT systems. The operator productivity level
for 3D printers with IoT systems is higher than 3D printers without IoT systems.
