Tushino Power Machine Tools specialises in implementing small to midsize hydro-electric power plants in inaccessible areas such as the Southern American Andes. The implementation of customised hydro-electric power plants for midsize towns yields a +20% improvement in efficiency when compared to competitive off-the-shelf products.

Tushino employs a team of expert mathematicians as well as advanced tools to calculate the most efficient turbine design for each specific project based on key values of water pressure, drop height and flow rate as well as environmental conditions at each power plant site.

Tushino uses their iPro 9000 SLA Production Center and Accura 60 material to turn the design into a master pattern for casting. This particular Francis-style turbine has 14 turbine blades, a diameter of 150cm and a capacity of 12 Megawatts. The QuickCast Stereolithography master pattern for investment casting weighs just 70kg, while the final cast model weighs 1990kg.

Traditional milling or CNC high speed machining can increase production time as well as cost for the turbines as each single blade would have to be milled separately and mounted to the body.

With the QuickCast build style a casting pattern is automatically produced unattended on 3D Systems’ SLA Production Center creating a hollow, honeycomb structure inside. This structure minimises the mass to burnout during the casting process resulting in a custom turbine in a fraction of the time.

iPro 9000 SLA Production Center is available in Australia through 3D Systems Asia-Pacific .
