PART ORIENTATION
POWDER BED FUSION - LASER
• Identifying the optimum part orientation in the powder bed will determine:
− The Overall Build Time (minimise the number of layers and part height)
− Minimum amount of supports necessary
− Best access to the supports to allow easily removal
− Optimum surface roughness
− Minimum Residual Stress (helps avoid part distortion)
Software to optimise support design
