About Zalewa Tec
Zalewa Tec GbR is a specialised manufacturing company from Großschirma in Saxony that focuses on the additive production of sand moulds and cores using 3D printing. Using the binder jetting process (3D sand printing), the company produces mould packages for one-off parts, small series and large series, which can be cast in aluminium, iron, cobalt, copper, magnesium, nickel, steel, zinc and tin as well as in non-metallic materials such as glass, plastic and concrete or mineral casting. In addition, sand-printed patterns (Zalewa Pattern) are produced with infiltration and coating, among other things as wear-resistant mould tooling for foundries. The services also include sample and spare part manufacturing, reverse engineering with measuring arm, 3D scanner and CT measurement, as well as application consulting and design. Customers come from the foundry industry, automotive industry, mechanical engineering, thermoforming as well as interior design and decor.

Materials and Processes
Sand (printing material)
Printing material for casting moulds and cores in the binder jetting process, compatible with common casting metals except titanium.
Aluminium
Common casting metal for the castings produced using 3D-printed sand moulds.
Iron
Casting metal for which the sand-printed moulds can be used.
Cobalt
Alloy system with which the 3D-printed sand moulds can be cast.
Copper
Casting metal for castings in sand-printed moulds.
Magnesium
Light-metal alloy that can be cast in the printed moulds.
Nickel
Alloy system for castings in 3D-printed sand moulds.
Steel
Casting metal for production in sand-printed moulds and cores.
Zinc
Casting metal; short-term permanent mould applications in zinc casting under development.
Tin
Casting metal; short-term permanent mould applications in tin casting under development.
Glass, plastic, concrete and mineral casting
Non-metallic materials for which the sand moulds can often be used as a casting mould.
