Abstract: Methods and devices for additive production of multi-materials are provided. Various devices may include a plurality of toolheads, each toolhead operably coupled to a different composition and having a kinematic coupling mechanism. The compositions may include a first composition comprising a cement paste or mortar, and a second composition comprising a thermoplastic polymer and/or an elastomeric polymer. The devices may include a moveable tool mount configured to be removably coupled to the kinematic coupling mechanism of each toolhead. A processor may be included that is configured to cause the deposition of the first composition and cause the deposition of the second composition simultaneous with the first composition and/or deposit the second composition after the first composition is deposited. Systems and techniques for toolpath creation may also be provided. In-situ structures may be provided that may include cement paste in contact with a thermoplastic polymer or an elastomeric polymer.

Abstract: A system for detecting a 3D printing error is described. The system comprising an image capturing device for generating at least one image of a first 3D print job creating an object and at least one image of a second 3D print job. The second 3D print job is creating the same object as the first 3D print job. The system also comprises an error detection module for comparing the at least one image of the second 3D print job to the at least one first image of the first 3D print job. The error detection module then triggers an error signal if a difference between the at least one image of the second 3D job and the at least one first image of the first 3D print job exceeds a threshold.
