It depends on what you want to do.
I have experience in 3DS MAX (Former ACI) and am learning Blender and 3D Coat.
I would imagine that Blender and 3D Coat would be able to either add thickness or some such.
If the scan results present a contiguous surface, here are steps to fix in 3DS MAX in almost any version ever made.

Thank you very much for such a detailed workflow - I will definitely give it a try.

1. Import model
2. Convert to Editable Poly. Much more robust than standard mesh type and better tools to work with. Z is the vertical axis in 3DS MAX and Cura.
3. Go to 'Element' Subobject and click around. If all of it gets selected, then it is properly welded into a single element. If it just selects portions, then do steps 4-6. If it selects all of the model while in Element Subobject, Then go to step 7.
4. Go into vertex mode and select all.
5. Choose the 'Caddy box' next to weld. The caddy is a modeless dialogue that allows you to change settings and test the result without having to try, undo and change, then try again. The Checkmark is the 'Accept and close Caddy' command. The red 'X' is the exit. The Green Plus symbol is accept and be ready for the next changes to try. I suggest check mark or red x until you are familiar with it.
6. Do a weld with the minimum distance threshold to make sure the whole model is one piece. Too high of a threshold and it will start to 'lump' vertices together and ruin the integrity of the scan. You basically only want to weld vertices that are either on top of each other or just really, really close.
7. Choose 'Border' subobject mode and click on the outside edge. This will select any edge that is continuous around a 'hole.' The outside edge will see the open space as a 'hole.'
8. With the Border (Edges around a hole) is selected, hold down the 'shift' key on the keyboard and move it downward away from the top. Clear a lot of area since you want to be able to grab stuff easily and then move to proper location. As a note, the shift and transform of anything in 3DS MAX is a cloning operation and will clone the edges/border while creating a connection/surface between the old and new edges/border.
9. With the new border (created during move and shift cloning) selected, go to the modifier panel and click on 'CAP'. This will create a polygon that seals the model into a manifold object.
10. Go to the Polygon subobject and select the new capped surface. Then navigate, in the modifier panel, to the make planar tab. This will make the polygon bottom flat. You can click the 'Make Planar' button or the x, y or z buttons next to it. Since it would be a surface scan as you linked to, I suggest the Z direction since it will flatten the bottom nicely. This is assuming that your new surface needs to sit firmly on the 0 (Zero) - Z axis point.
I hope that made sense.
