DED-CLAD®-p
Laser powder additive manufacturing

The CLAD® (direct additive laser construction) process developed by IREPA LASER is an industrial additive manufacturing process that consists in melting metal powders with a laser to make functional technical parts by building up several successive layers (principle of 3D metal printing). This process is part of the DED (Direct Energy Deposition) family.

DED-CLAD®-p additive manufacturing

The CLAD® (direct additive laser construction) process developed by IREPA LASER consists in melting with a laser metal powders injected in a nozzle in order to constitute a deposit in fully controlled dimensions.

By applying several successive layers of material, functional technical parts are made through additive manufacturing (principle of 3D metal printing).

This process is part of the DED (Direct Energy Deposition) additive manufacturing family of processes.

Uses

Additive manufacturing allows the construction of three-dimensional parts through the addition of successive layers of material.

This DED manufacturing process is chiefly used in different areas of industry such as:

Aviation (engine parts repair, MRO)
Space
Defence
Medical engineering (implantable devices)
Energy (components of turbines, exchangers etc.)

Benefits

Reduction of the unit cost price
Reduction of manufacturing lead times
Material yield > 90 %
Reduction of fixed costs (no moulds or tooling)
Reduction of cost and material supply times

Advantages

Very high metallurgical quality
Manufacturing of single pieces and small runs
Parts with large dimensions (up to 1500 x 800 x 800 mm)
High construction speeds (up to 250 cm3/h)
Making of parts with graded materials (FGM)
Optimisation of parts thanks to a combination of different processes (SLM + CLAD®)
Accurate control over the deposited materials
Use of just enough material
Improved surface properties
Control of wear, oxidation …

Examples of applications

Additive manufacturing is used in different industries: aviation (engine parts repair, MRO), space, medical engineering (implantable devices), energy (components of turbines, exchangers etc.).
