Direct Energy Deposition

Direct Energy Deposition

Powerful and Advanced Manufacturing Solution for Direct Energy Deposition (DED)

The ModuleWorks Direct Energy Deposition (DED) solution is tailored for organizations offering CAM software solutions for powder welding components used with machine tools or robots. This includes CAD/CAM software developers looking to break into the additive manufacturing market, as well as robot integrators, robot OEMs, machine tool builders, and welding hardware manufacturers who develop solutions for this process. With ModuleWorks DED, these companies rapidly develop innovative and powerful DED solutions and features and get them to market fast. Typical DED applications include repairing and rebuilding the worn surfaces of pre-machined metal forms, such as metal forming dies for car body sheets. ModuleWorks DED also supports the EHLA technology.

Major Challenges

optimize

Optimization of Parameters

DED is a complex and sophisticated manufacturing process requiring accurate control over various deposition parameters such as feed rate and laser power to ensure a stable result and near net shape structure.

DED-defect

Reducing Defects

DED is also prone to a number of defects such as porosity and distortion of the laser spot. Controlling the repeated cooling cycles during layer-by-layer deposition is vital for high quality results. Consistent nozzle orientation is also crucial for keeping the surface perpendicular, thereby minimizing distortion.

Post-Processing

Post-Processing the Part

Parts manufactured using the DED process often require post-processing to achieve the final surface quality and required precision. This includes additional machining to finish the surface with the desired dimensions while staying within tolerances.

Solution Offered by ModuleWorks

ModuleWorks Direct Energy Deposition (DED) is an advanced and proven solution optimized for multi-axis, multi-layer additive manufacturing processes. It comes with an integrated toolpath planning algorithm specially designed for complex geometries and customized structures. Precise control and adjustment of process-critical parameters enable specific wall widths and heights (multi-layer) with maximum deposition efficiency, resulting in near net shape parts that require only minimal post-processing.

Key Features

This feature allows users to divide the workpiece into separate segments and produce each segment with its own toolpath and individual parameters. This approach provides more control over the weld deposition sequence, offers more flexible path planning, and results in fewer link motions.

Select the optimal toolpath pattern based on your part geometry or specific requirements. ModuleWorks offers a morph toolpath pattern that automatically adapts to the contours, creating continuous and efficient toolpaths. The morph pattern offers a full range of toolpath options and settings. It is also possible to generate parallel or spiral patterns.

Automatically create different start points for each layer, reducing material deposition at a single start point across layers.

This option fills holes or voids in the toolpath pattern for efficiently building a continuous part surface. If holes need to be avoided, additional retract moves are added to the toolpath on the containment boundary.

Key Highlights

Advanced Toolpath Generation for Complex Geometries

The solution is based on freeform slicing and supports up to 6-axis toolpath calculations. The pattern is driven from a base curve, or a drive mesh surface, and all weld slices are created as 3D-equidistant paths from that contour. Various options allow precise control over the toolpath. Additional options like support for constant distance between the welding slices, lead/lag angles or side tilt angles, full collision avoidance and multi-layer welding toolpaths ensure optimum toolpath generation. Precise control over the direction and movement of the nozzle ensures the optimum angle for each manufacturing process, resulting in a consistent melt pool.

Hybrid Manufacturing

Easily switch between additive and subtractive manufacturing processes to rapidly build finished parts and implement closed-loop processes. The industry-proven, best-in-class subtractive manufacturing toolpaths from ModuleWorks integrate seamlessly with the DED technology for end-to-end hybrid manufacturing of high-quality finished parts. The solution is ideal for hybrid machine tools, robotic systems, and powder nozzle additive manufacturing. Fast and intuitive programming of 5-axis simultaneous toolpaths and full simulation of both DED and milling processes deliver optimum manufacturing flexibility and safety.
