I made an model using 3ds max, and export it into an stl file, but when I opened it using slicer, the scale was completely off. The model size was also much smaller when I opened it with slic3r. What is wrong?

It´s the same with blender I guess. Even if you use blender units or meter in blender as soon as you save as .stl it gets shrunk by faktor 10. So in slicer I scale by 1000% and then its normal size.

I use Blender, set to metric units and I do the scaling up within it. For example, if I want a cube with 20mm sides, in Blender I set it to have 20m sides. This way you minimise software arithmetical errors.

Why does 3DS MAX, and Blender rescales the .STL data file?
Any other CAD software doing this?

thanks for the info, this might be my problem too. I'm using inventor, and all files are scaled by 0.1.
