Excellent surface finish and with ability to accommodate very complex shapes.
With investment castings, the biggest limitation is the length of travel of the molten metal from the
runner. 50cm is an adequate rule of thumb for the max travel permissible.
The longer/larger the casting the less accurate it will be. The rule of thumb is +/-0.1mm for the first
25mm of travel and 0.02mm for each centimeter.
