Investigation of the Effects of Roller Spreading Parameters on Powder Bed Quality in Selective Laser Sintering

Powder spreading is one of crucial steps in selective laser sintering (SLS), which controls the quality of the powder bed and affects the quality of the printed parts. It is not advisable to use empirical methods or trial-and-error methods that consume lots of manpower and material resources to matc...
