Methods and apparatuses for sealing mechanisms for realizing adhesive connections with additively manufactured components

An apparatus, comprising:

• an additively manufactured node including a surface;
• and
• an elastomeric member attached to the surface;
• and
• an expandable substance arranged between the surface and the elastomeric member, wherein the elastomeric member is configured to deform in response to a pressure applied by the substance when the substance is expanded, such that the deformed elastomeric material extends away from the surface.

A method of forming a seal between an additively manufactured node and a structure, the node including a surface bounding a recess, the method comprising:

• attaching an elastomeric material to the surface;
• depositing an expandable substance, such that the substance is arranged between the surface and the elastomeric material;
• inserting the structure into the recess;
• and
• expanding the substance, wherein the elastomeric material deforms in response to a pressure applied by the substance when the substance is expanded, such that the deformed elastomeric material extends away from the surface and contacts the structure.
