Indeterminate Design revisited the challenge of 3D printing a screw compressor, sharing the process in a video and providing downloadable 3D printable files. The complexity of the screw threads and the need for precise meshing between them make this project non-trivial, especially considering the optimization of the rotor shapes.
In the video, Indeterminate Design explores the engineering principles behind screw compressors and addresses the challenges encountered in a previous attempt. The rotor profile is a critical aspect of the design, and a Python script is employed to extract data from an existing profile and generate suitable 3D printing data.
The finished 3D-printed screw compressor exhibits a loud operating noise, and the project is noted as “extremely dangerous.” The screw printing was outsourced to a service using a special high-temperature resin. Despite initial challenges, the final screws were printed successfully after numerous attempts, and other components underwent multiple iterations to achieve the correct sizes. This project offers a fascinating insight into the intricacies of 3D printing a functional screw compressor.
