Laser Additive Manufacturing
The New System from ALT
ALT is now producing a new system for component building by the Laser Deposition method. The new system has been designed with flexibility and robustness in mind from the start. Parts can be built from scratch or modified by adding new structures. ALT’s new system promises to substantially reduce post processing of parts compared to competing systems.
What is Laser Deposition?
Laser Deposition is a laser technique to build or modify metal parts directly by using laser-fused metal powder.
Powder-fed laser deposition is the fused bonding of an additional material on to a component with the help of a laser beam. Repeating this process layer by layer allows a fully dense metal part to be built in a manner similar to 3D Printing. Alternatively, a single layer of material only can be added to a pre-existing surface in a process called Laser Cladding. Cladding coating materials are chosen based on their technical purposes, i.e.to provide corrosion resistance or greater wear resistance.
After thorough research, and investments in new in-house laser facilities ALT areable to use their expertise in additive manufacture to act quickly and accurately to meet new customer's demands.
Can be used to:
- Produce functional prototypes
- Repair or modify high value components
- Vary metallic composition
- Low heat input into substrate –low distortion
- Controllable dilution of layers into substrate or previous layers
- Precise deposition with good height control –reduced machining (typically less than 0.3mm removed to produce machined surface)
- Can be used in atmospheric or anaerobic conditions
Laser deposition applications include:
- Bearing surfaces: Heavy equipment for mining, construction, agriculture
- Seal Surfaces: Oil recovery and refining
- Pump Components: Pulp & paper
- Drive train parts: Food and chemical processing
- Turbine blades: Automotive
- Extruders: Aerospace
- Mining bits: Coal and Nuclear Energy
- Forging dies: Steel Manufacturing
