Schematics showing the different types of hatch styles that are employed during the SLM process. The building (BD), scanning (SD), and transverse directions (TD) are indicated. Sample A—scan with unidirectional vectors; sample B—bidirectional vectors that reverse between each hatch; sample C double scan strategy, firstly with bidirectional vectors in TD and secondly scanned with bidirectional vectors in SD; sample D—scan with island strategy with 90° rotation but without shift and sample E—scan with island strategy with 90° rotation and 1 mm shift between the layers [71].
