  • Systems and methods for 3D printing with multiple exchangeable printheads
    Publication number: 20220055300
    Abstract: A modular 3D printer system can include a base subsystem and multiple exchangeable components. The base subsystem can have a 3D motion module, a printhead module and a platform module. The multiple exchangeable components can include printheads having different configurations and functionalities, which can be exchangeably installed in the printhead module. The multiple exchangeable components can include platform supports having different configurations and functionalities, which can be exchangeably installed in the platform module.

  • Methods to form 3D objects using cross-linkable or sinterable materials
    Patent number: 10137642
    Abstract: Methods to form cross-linked or sintered objects include forming walls for reservoir layers, with cross-linkable or sinterable materials deposited in the reservoir layers. The cross-linkable or sinterable materials can then be cross-linked, e.g., changing the structure of the deposited cross linkable materials, or sintered, e.g., heat treated to fused the sinterable materials together. The walls for the reservoir layers can be removed after the objects are formed.

  • 3D printing systems and methods
    Publication number: 20180099457
    Abstract: The coupling between the plunger and the piston can be removable. The removal of the plunger can form a split syringe, which can be used for ease of transport. The split syringe can be mounted on a print head for printing using a 3D printer.
