HP's Multi Jet Fusion (MJF) can be used for both prototyping and small-batch-production of functional plastic parts.
SLA is most suitable for visual applications where an injection mold-like, smooth surface finish, and a high level of feature detail are required.
Binder Jetting is most commonly used for full-color parts, low-cost metal printing, and large sand casting molds.
Material Jetting produces parts of the highest dimensional accuracy with very smooth surface finish, used for both visual prototypes and tooling manufacturing.
SLS is used for both prototyping and small-batch production of functional plastic parts with good mechanical properties.
DMLS/SLM produce high performance, end-use metal 3D printed parts for industrial applications in aerospace, automotive and medical.
FDM is the most widely available 3D printing process, mainly used for low-cost prototyping and design verification with very fast turn around times.
