I am a part of a project team at my university and we are looking into using 3d printing to design battery containers. In the past we have always machined a thick acrylic however our current project a detailed container to be built several times over and it isn't practical to make it by hand. So we've turned to 3d printing as a viable option. However, our main concern is the possibility of disintegration of the material in the presence of our chemicals.

We are working with a concentrated solution of Potassium Hydroxide (KOH), Activated Carbon, and aluminum. We need the box to be rigid, and non-reactive. Does anyone know what type of material we should pursue for this use or if it is possible at all?

Thank you!

However, if you review this video you'll see that the WSF material is rather porus.
I would be very concerned about long-term seepage of caustic fluids.]]> stonysmith 2013-02-25T16:02:57-00:00
