Abstract Scope |
In a given additive manufacturing system, there are numerous variables that can impact the product of that system. Additionally, many of these variables, such as environmental temperature or humidity, may not be directly monitored or controlled. This can cause issues in applying machine learning approaches, as the quality of the output of the additive manufacturing system may appear to diminish or drift over time with these unmonitored variables and the data collected in earlier iterations may not accurately describe the current state. We explored how to address this problem using Gaussian process regression and an informed uncertainty methodology. Machine learning models were then applied to direct ink write printing to create arched spanning structures over a 4 mm gap. Image capture and processing was used to score the prints against specific target geometries and enable closed loop experimentation and optimization to these targets. |
