Demonstrate how to work with 6-axis directed energy deposition (DED) and 6-axis laser (lsr) vector files.
Video length (3:27).
Sample files for use with the tutorials are available from the
Downloads page. Expand the downloaded ZIP archive into a convenient directory from which you can import files into
Local Simulation as you need them.
In Simulation Utility, click
Simulation menu > New, then in the
Simulation Utility dialog, click
DED and
Create Simulation.
The
Import model dialog opens.
Browse to where you saved the Examples files, and in the Example_24 folder, open the file
6AxisPath.lsr.
In the Substrate dialog, select
Import Substrate Geometry, and click
OK.
Browse again to the Example_24 folder, and open the file
6AxisSubstrate.stl.
In the
Converted model units dialog, click
OK.
Upon import, observe the curved laser path on a double-curved substrate.
On the
Home tab, click
Machine; set
Absorption efficiency to 19% and
Material to AlSi10Mg, then click
OK.
Click
Build Plate > Properties tab; deselect
Match part deposition material, and set
Material to SAE 304. Note that unlike standard DED simulations, with 6-axis DED simulations you can specify the substrate material.
Also on the
Properties tab, under
Thermal conditions,
Heating, set a
Controlled temperature of
80° C, then click
OK.
Click
Solver Settings > Results tab, and select
von Mises stress to record this stress type during simulation, then click
OK.
Click
Mesh Settings, and set the values shown for
Elements per heat source radius (1),
Fine layers below heat source (3), and
Adaptivity levels (3).
Click
Mesh Preview. If you have not already saved the project, you will be asked to do so.
Assured the mesh looks fine, click
Solve to start the simulation. This will take about an hour to run on a 4-core computer.
When Results appear, examine the Displacement and von Mises stress results. Note the large number of increments in the simulation results.
