One of the challenges in making funnels is mold design. The cavities of the molds must be precisely made so that the cast material can flow properly. The problem is that many types of funnels are needed, which means a lot of molds. In smaller series, this represents very high costs. However, one of the electrical manufacturers decided to invest in some 3D printers instead of making so many molds. Using them, they ensured a faster production of funnels, while at the same time the costs were much lower. In the past, they have had to hire trade experts or even outsource the order. In conclusion, this one and only solution was also expensive, so they figured out it would be more efficient if they purchase and have 3D printers in their own company.
