ExOne Sand Printing Process

  • Published on Sep 18, 2012
  • This video demonstrates ExOne's digital part materialization (3D printing) process for printing sand casting molds and cores, beginning with a digital file, going through solidification analysis, printing and finally casting a finished industrial part.

    Interesting, I was expecting the sand molds to have a sort of stepped appearance as in plastic 3d printing but the use of fine grains probably prevented this.

    Very nice video. That's a pretty cool process. I think there is potentially an opportunity to move downmarket into the DIY community. A moldmaker in every garage.

    Love the process video, but the breakout however shows a failed casting above the logo where the mold was incompletely filled! Also, lots of flashing at parting lines, which you did not show cleaning up!

    What a great video - this is how to do a technology demonstration folks.

    what does a company charge to make a sand mold from a solidworks model?

    I was wondering the same thing. this cant be like good ol' green sand. i figure once the resin is set it has to be bonded hard as a rock.
    On a side note that guys should really be wearing a mask, even though he is at a down draft table.

    I wonder what kind of sand and activator is used and what kind of quick drying resin is or can be used on a home project.. I have the system projected and partialy built , from the heads to deposit the resin, the dumpster to lay down the sand layers up to all the mechanical structural parts and electronics/software.. If anyone can help me with this information I will receive it gladly since I have not much experience with chemistry ... Thank You

      @Fernando , did you have any luck Fernando? I know it is 4 years later, but maybe you still want to try?

    Why aren't the sand workers wearing supplied air hoods?
