LWS 3D Metal Wire Printing
LWS novel (Patent pending) 3D metal wire printing system is based on laser melted wire deposition, and offers advantages over existing systems:
➢Object’s dimensions are not limited – vacuum chamber not needed.
➢Wire used is available and compiles with existing standards (AWS, AMS, etc.).
➢Stainless Steel, Alloyed Steel, Titanium, Bronze, Nickel and Cobalt Alloys, etc.
➢Productivity depend only on laser power
➢Single session can include two or more types of materials and/or wire diameters.
➢Ability to print on existing pre-machined or printed parts.
➢Deposited material quality is as good as filler wire.
Laser Metal Deposition - WIRE
➢3D manipulated laser is used to melt the surface of a substrate, creating a localized pool of molten metal into which a metal wire is fed to form a bead. The melt pool is manipulated along a 3-D path to create a net-shaped (or near-net-shaped) component bead by bead onto the substrate in layers
➢The process is highly efficient compared to current powder based Additive Manufacturing methods, which waste an enormous amount of expensive raw materials.
➢LMD-W process is ready and already applied on several applications. We continue our development to extend the scope of applications.
Our Technology – LMD-W by LWS
➢Patent pending
➢Fast : > 5 Kg /h (with 2kW Laser)
➢Enables deposition on all 2D axes
➢Using all standard metal wire with diameters of 0.4 mm to 2 mm or thicker (depending on laser power)
➢Enables two (or more) different wire material or diameter at the same printing session
➢No limited working area since no chamber or vacuum is needed
➢The throughput of the system depends only on laser power
➢Printing head can be installed on Robotic Arm
➢The Metallurgy of the printed parts are similar to the wire material
➢The printing results are compatible with welding standards as AWS 17.1 and AWS 1.1
Application opportunities
➢Design a new manufacturing sequence using a combination of manufacturing processes that reduces cost, material usage, work in progress, and cycle time
➢The system can be implemented as a stand alone unit in metalworking factory to produce near-to-shape semi-finished parts, or may be implemented in a multi-axis metalworking machine as a integral part of the process.
➢Users can select a part build strategy (including pre-machined parts, geometry of deposition, path planning, deposition rate, etc.) and combine it with a finishing strategy
➢Printing can be done on existing parts
➢Easy switching between different materials
➢Versatile structure design
➢Deep pockets
➢Complex design with added structure
➢No evidence of lack of fusion, pores or material oxidation
