Figure 7
The illustration presents a graph with “Temperature (degrees Celsius)” on the vertical axis, which ranges from 200 to 900 with an interval of 100. The horizontal axis is labeled “Time (seconds),” ranging from 270 to 340 with an interval of 10. The legend on the top right clarifies the labeling of the paths as “The best L B path” in a green line and “The worst L B path” in a red line. The green curve starts above 850 at time 272 and decreases rapidly to around 490, and then bends towards the right and still decreases gradually, which ends around 260 near the time of 332. The red curve starts around 800 at time 272 and decreases rapidly to around 380, and then bends towards the right and still decreases gradually, which ends around 230 near the time of 332. Above the curves, two heat maps are shown related to the green and red curves. Both substrates are rectangular, and a rectangular deposition layer is placed on their top surfaces. A color scale on the left ranges from 100 in blue at the bottom to 1000 in red at the top. The left substrate is labeled “at the rate t equals 271.4 seconds.” It is shown in the light blue and green region with a small red patch at the top left corner. The central region is shown in blue in a circular pattern, which is merged at the front edge. The right substrate is labeled “at the rate t equals 271.4 seconds.” It is shown in the light blue and green region with a small red patch at the bottom right corner. The central region is shown in blue in a circular pattern. Note: All numerical data values are approximated.Temperature distribution at the end of the AM process: (a) for the best LB path and (b) for the worst LB path. The maximum temperatures of the plates during the cooling phase (starting at the end of the AM process at time 271.4 s) are shown by a green line for the best LB path (lowest deformation) and by a red line for the worst LB path (highest deformation).
