| Abstract Scope |
The combination of 3D imaging and additive manufacturing systems has given rise to novel in-situ monitoring and error correction techniques allowing for increased efficiency and reduced operational costs. A novel method of the coordinate system calibration for a fused filament fabrication printer and digital fringe projection (DFP) scanner was developed. A single layer rhombus outline is printed with known G-code coordinate corners. The shape is scanned and a series of image processing and DFP techniques yields the corner locations in scanner coordinates. The number of scanner and G-code data points are increased using linear interpolation between the corners to improve accuracy. The transformation matrix is calculated. With this, scanned data can easily be compared to the ideal print geometry leading to improved monitoring and correction. Preliminary results indicate the calibration method has acceptable accuracy. When used in underfill correction techniques this method has proved to be effective and reliable. |
