3D Printing

Choose a 3D printing process by what the part needs to demonstrate. FDM is useful for early fit checks and workshop fixtures. Consider SLA when fine detail and surface appearance matter. SLS and MJF can be evaluated for functional polymer parts, particularly when the geometry is complex or several parts need to fit together.

Metal 3D printing is a separate option for suitable alloy parts with internal channels, lattices or other features that are difficult to reach with cutting tools. Before choosing a process, identify the main load direction, visible faces and mating dimensions. Check access for cleaning, support removal and any finishing the part needs. Read the design rules for 3D printing.
