Hi everyone
I want to engrave into steel around 5mm to make some dies for pressing
Does anyone know if you can engrave in layers with a fiber mopa laser, or must it be a 3d laser?
You can using the 3d slice mode. There are tools to take an STL and create a depth map. It will take some experimenting to get the depth dimensionally accurate. For that depth you likely want a longer lense to increase the range of good focus. The max Resolution is 256 layers, but you can increase the depth by running multiple passes per layer.
The issue is as you get deeper, you are getting further from the optimal focus.
Another tip is to include regular cleaning passes, to keep consistency of the surface being ablated. And, depending on the power of your laser, it might take a long, long time!
Thanks a lot for your reply on this fins!
What I need to do here, is create a hollow - circular / oval shape in two pieces of steel, which would be pressed together, to create the die
It is important the steel must have a precise volume of material removed from it to create the hollows
Each hollow would only be = 600 mm3 cubic-millimeters (so 1200mm3 total volume)
While achieving the correct volume, I need to get a concaved shape on both sides of the die - so the end product will be symmetrically round oval
Would you say this is possible, and is it simply going to be a matter of trial and error to get it right?
Hope I have described what I am trying to do
