Binder Jetting Process

The binder jetting process uses two materials：a powder based material and a binder. The binder acts as an adhesive between powder layers. The binder is usually in liquid form and the build material in powder form. A print head moves horizontally along the x and y axes of the machine and deposits alternating layers of the build material and the binding material. After each layer, the object being printed is lowered on its build platform.

Sand 3D Printers

Sand 3D printers from EasyMFG support sand casting applications across industries, providing an enhanced design methodology for their product development.

As the leader in binder jetting sand 3D printing, EasyMFG offers solutions for complex and increasing customer demands that cannot be realized by any other conventional production process.

System Benefits

 

1) The print head is not easy to clog, auto clean function

 

2) Waterfall type powder feeder can be compatible with multiple sands

 

3) Real time slicing and RIP algorithms for layered manufacturing. Can adjust the technological parameter freely

 

4) Independent intellectual property rights, self-developed software

 

5) Fine tune the dosage of binder

 

6) Mix the hardener into the sand while running
