General explanation
Printing strategies
Straight lines strategy: several welding beads overlapped next to each other
Oscillation: continuous zig-zag bead that fills the entire layer
Heat treatement
Stress relief: due to the high residual stresses build up in the WAAM product, this heat treatment is necessary to minize residual stresses.
