Design, development, and implementation of 3D-printed polylactic acid centrifuge rotors for laboratory-scale applications

In this work, self-made laboratory centrifuge equipment was developed for the separation of suspensions and immiscible liquids. This centrifuge was based on the Arduino microcontroller and fabricated from simple and recycled mechanical and electronic parts, spending an inexpensive budget suitably. The centrifuge frame and rotors were manufactured of Polylactic Acid (PLA) filaments, which were printed in a 3D printer. Two rotors labeled R50 and R15 were designed and fabricated to use tubes of 50 mL and 15 mL, respectively. The maximum speed reached, without vibration interferences, was 3350 and...
