Metals Additive Manufacturing
Metal 3D printers use a process commonly known as "laser powder bed fusion". This process uses a high power laser to create complex geometries by selectively melting metal particles in a layer by layer fashion.
How does it work?
Starting with a CAD model, "slices" or "layers" are created via software to specify the laser scan paths, speeds and powers needed to melt the powder feedstock.
The printer lays a powder layer on top of a solid metal plate, and a high power laser "draws" the first layer of the part, melting and fusing the powder into a solid cross section.
A second layer of powder is laid on top of the solidified part, and the process is repeated until the part is complete.
The completed part is then removed from the printer and all the unfused powder is removed.
The part then goes on to post processing to finish the last details, such as taps and specific surface finishes.
What can be done?
Printed metal parts have mechanical properties on comparable to traditional manufacturing processes such as CNC or casting.
High complexity is the ideal match for metals additive manufacturing, as features impossible through other processes are possible via LPBF
- Internal cavities
- Organic shapes
- Assembly consolidation
- Integrated articulations and mechanisms
Internal cavities and organic designs can create lightweight components with better mechanical performance
