A modular ceramic binder jetting 3D printer was created from scratch for advanced biomedical and aerospace applications. The primary objective is to increase the mechanical properties of a final part by maximizing powder bed packing density. To accomplish this, we set primary criteria as effective powder spreading, powder bed temperature control, and isolation of the printing environment from outside. Our secondary objectives consist of increasing printing resolution, improving both software and firmware, and obtaining a scalable print volume while keeping the printer open-source, affordable, and user-friendly. Some updates regarding the original design were made to solve the issues during assembling. Belt tensioners were re-designed for a robust connection. A full enclosure was created for a closed printing environment. Future modifications and improvements include re-coding the slicing software and Marlin firmware, adding bed heating resistors, and creating a replacement boost-demultiplexing circuit board for an ungraded jetting cartridge. Moreover, the scalable print volume will simultaneously allow large part dimensions and minimal consumption of expensive materials. By tailoring our printer under different application scenarios, it will ultimately save material, lower printing time, and increase dimensional accuracy.
