For die casting, usually you need invest a lot on the die firstly. Then later you can save a lot cost on the part made by the die. For example, you need to make an aluminum middle sized die casting cover (around 800g), you may need to invest 4K USD on the die casting tooling. But later in mass production, the cost /pcs maybe be around 3-5USD. However, if you use 3D printing , although there is no cost for tooling. The U/P will be around 100-300USD. For sure if the structure has more complicated structure like ribs or slots, the cost will be more.
