Description

This project presents an automated pipetting device capable of decapping and recapping a group of cryovials, as well as accurately transferring liquid into the vials. Specifically, the code files (the “Code” folder) contain the host PC control program. The “Marlin” folder includes the modified Marlin firmware; users can compile it in Visual Studio Code using PlatformIO, and detailed operating procedures are provided in Section 6.1. The “SLDPRT” folder contains the SolidWorks source files of the present design, which can be further modified by developers. The “STL” folder provides the STL versions of the design files, which can be directly used for 3D printing. To ensure structural strength and durability, the Ratchet Linkage Shaft is printed in PA6-CF with an infill density of 50%, whereas all other parts are printed in PLA with an infill density of 90%.
