| What is "Additive Manufacturing"? | | "Additive Manufacturing" technology first emerged in the 1980s and was
used to print plastic objects with a technique known as
Stereolithography (SLA).
In SLA an ultraviolet light beam is used to selectively cure a photosensitive polymer to build up a part layer by layer.
Later other processes for printing plastic objects emerged such as Fused Deposition Modeling (FDM).
In FDM a thermoplastic filament is extruded from a nozzle and heated to build up an object layer by layer.
Laser-based additive manufacturing is another technique used to print metallic objects.
The
two most commonly known methods available for commercial use today are
“Powder Bed Fusion” (PBF) and Powder Fed “Directed Energy Deposition”
(DED) systems.
PBF systems use a laser to selectively melt a bed of metallic powder layer by layer to build up the physical part.
After the first layer is spread and sintered, the bed is filled again with a second layer of powder and selectively sintered.
This
process is repeated until the part is fully formed. The end result is
buried in the powder cake and is not visible until the excess powder is
removed.
In Powder Fed DED systems metallic powder is
continuously blown through nozzles directed at the focal point of a
high powered laser.
The resultant molten pool of metal is then moved using a motion control system and the part is built up in free space.
The entire process is visible as the part is grown layer by layer
Powder
Fed DED systems, such as LENS offered by Optomec, also can be used to
add material to an existing metal part for example to repair it, add an
engineered feature or wear resistant coating, and for hybrid
manufacturing applications. |

| What is "Hybrid Additive Manufacturing"? | | In 2014 a number of equipment suppliers introduced hybrid CNC machines
where additive and subtractive processes could coexist on the same
machine tool.
The synergy of these two technologies integrated in
one machine tool platform offers a number of advantages to the metal
working industry including lower deployment cost, reduced learning time
and risk, and increased manufacturing flexibility. |

| The benefits of Additive Manufacturing: |
| | | Lowers overall production costs by reducing costs of materials and assembly. | | | | | | | | Reduces time to market with a digital process – no hard tooling required. | | | | | | | | Enables more materials and feature size options. | | | | | | | | Can produce lighter weight structures with internal hidden cavities. | | | | | | | | Increases design and manufacturing flexibility, reduces the number of processing steps. | | | | | | | | Supports a full range of use models, from prototyping to repair/replacement to full production. | | | | | | | | Integrates within traditional production environments. | | | | | | | | Reduces environmental impacts. |
