Our EPT 3D Printing gives great convenience to sand molding of foundry objects, digital designs in CAD are readily 3D printed into sand molds that are not easy to be accomplished and modified if any by traditional molding methods, no more conventional tooling, plating and supporting structures are needed in heavily polluted workshop environment.

The 3D printing technology is mostly suitable for objects that are of complicated geometry, multiple angles and hollowness, traditionally such could be molded first in separate parts and assembled again into one final mold, now EPT 3D printing shall mostly build whole sand mold once off in the single print bed.


  • Cost-effective and time-saving 

  • Mold/core accuracy tolerance within +/-0.3-0.5mm 

  • No hassle for parts or prototype in less volume 

  • Most applicable for objects with complicated geometry, hollowness and multiple angles 

  • Visual CAD digital patterns quickly 3D printed into solid sand molds without concerns of conventional complications 

  • High precision and high speed printing 

  • In time of parts modification, only clicking in digital

  • CAD instead of tooling changes repeatedly

  • Volume in large build welcomed with same precision 

  • Almost infinite free thinking in pattern designs, always available to be printed physically 

  • Friendly to various metals in casting
