Anyone try this STL to PNG converter? From what I understand it emulates what a 3D laser machine can do using a grayscale height map image from an STL file. Looks like any old grey scale height image I’ve seen, nothing special. ? I guess its supposed to work on a 2D-only fiber laser? OR do I have this wrong?
Im on a 60 W Fiber JPT M7 MOPA
Will it work on my machine to create 2 1/2 D - 3D engravings?
In Lightburn it’s called 3d slice. I haven’t tried it yet, the following should help
That is part of LB OMG that’s awesome! Thank you.
I don’t know what you expect, it’s a gray scale image… That is how the 3dslice option works, it uses a grayscale input… The difference is where the light and dark scaling is placed.
Some grayscale images can be used in the 3dslice option but most will not be properly transposed as 3d.
An image with very dark areas will burn deeper than light areas. If it’s caused by shadows it won’t look correct, that why they start with an stl object that is 3d.
Run the stl2png with the a different orientation of top or side and you will see the difference.
This is a leaf image I picked up somewhere on the Internet, no processing and it turned out pretty good for slate, tile and 3d engraving on the fiber…
If you still have some issues, sing out…
I have tried it several times. It will only work on images that are less than 100 megs. I haven’t tried one yet that worked.
I think what you’re doing in Photoshop should work…
I think they end up as more of a byte map … each has an 8bit value.
Can you export it as an 8bit gray scale?
