Large forming space

EP-C7250 rapid prototyping system can make the part with the size of 700mm*700mm*500mm, therefore, regular size parts can be made and subsequent aligning is not required.

Reliable performance

EP-C7250 optimises the round roll powder laying system with high stability, the yield is greatly improved.

Multiple functions

EP-C7250 can not only 3D print various kinds of plastic samples, but make wax mould and sand mould for casting. Perfectly combined with traditional foundry industry, EP-C7250 realizes the core making without using mould and greatly reduces the R&D and trial-producing time for casting parts in different industries.

Powerful Material development abilityEP-C7250’s sintering parameter has been hyalinized to realize users’ R&D requirements for new materials. Users can change for more kinds of powder and adjust the properties like strength, details and appearance, etc.
