Stacking pitch” and “extrusion width” are used in the MEX method. Stacking pitch” is the height of stacking in the 3D Z-axis direction. It can be as small as 0.01mm. The most commonly used pitch is 0.2mm. It is a good balance between molding time and quality. Extrusion width is the thickness of the line when the object is viewed from above. It is affected by the nozzle diameter. In most cases, a 0.4mm nozzle is installed as standard. Optional products such as 0.2mm nozzles are available.
