Estimating the term…
The present application relates generally to systems and methods for using machine vision to provide information on one or more aspects of an additive fabrication device, such as calibration parameters and/or an object formed by the device or in the process of being formed by the device. According to some aspects, a method is provided for calibrating an additive fabrication device. According to some aspects, a method is provided for assessing at least a portion of an object formed using an additive fabrication device. According to some aspects, a method is provided for fabricating a second object in contact with a first object using an additive fabrication device. According to some aspects, an additive fabrication device configured to perform one or more of the above methods may be provided.
A method for additive fabrication of a three-dimensional object comprising a first part including an auxiliary object formed prior to the additive fabrication of the object and a second part in contact with the first part, the three-dimensional object having an original model representing a three-dimensional structure of the object, method comprising:
The method of 12, further comprising, prior to positioning the first part on the build platform, calibrating relative locations and/or orientations of the build platform, the imaging device, and the one or more jets to form calibration information, and wherein modifying the original model includes using the calibration information in combination with the first three-dimensional model.
