I am sitting here reading about Formus' TSF technology and it says that it
positions the printhead nozzle about .5 inch below the surface of the sand
and sprays a layer of molten wax into the sand. Is this correct? How do
they prevent blockages? How deep is the layer? I suppose they are
building upwards? They can build parts 11ft x 6ft x 4ft in a few hours?
Anybody with experience or useful input?
