The disadvantages are that the resolution on the z axis is low compared to other AM process ( 0.25 mm ) , so if a smooth surface is needed a finishing process is required and it is a slow process sometimes taking days to build large complex parts .
 process parameter: resolution; manufacturing process: AM process; manufacturing process: mm; concept or principle: smooth surface; manufacturing process: finishing process; concept or principle: process; process parameter: build
