I am interested in 3d printing from aluminum valve cover for car SAAB valve cover
I am thinking of creating 3d scan and the placing order with i.materialize or similar online services.
I am curios if this is feasible at all, since I am interested in 3d printing functional part not just a souvenir. Also since 3d part does not have smooth surface, will sand blasting help without affecting dimensions?
Also what would be an approximate cost of 3d scanning and printing?
I really do not know where to start and would appreciate any directions.
