Our company printed a series of sand moulds sets for producing castings from heat-resistant steel (temperature - 1800 С). The total weight of the forms exceeded 700 kg, six parts were cast in it, they were weighing from 800 kg to 1100 kg.
Printing of the moulds for each casting took 10 hours. According to the traditional technology, the production of equipment would take 5 months and cost about 500 thousand rubles for each set of form. Thus, the economic effect only on printing forms was about 2.5 million rubles, and the speed of making forms using the method of printing them on our equipment was reduced to several days.
