This a fun little piece of work that has been around as a test part in various forms, sizes and materials.   In fact, we have this object in almost every material that we have in the lab.    The concept of creating a design and then producing it “automagically” in different materials is in keeping with the ideas being put forth at the “Center for Bits to Atoms” at MIT.

It is a simple hyperboloid sized to allow it to be used as a building block for more complicated forms.

    Are these pieces made with the new Spectrum glass powder? Was the pot from the previous post (10/23) made with the recycled powder? Did you process the recycled glass powder to 400 mesh as you do with the Spectrum glass powder? I noticed that there was a reduction of the ratio of glass to non-glass organics from earlier recipes when you used the Spectrum glass. Is this due to a finer grind of the glass powder? Or some other factor?

    Thanks , Jeff

    Jeff, yes they were made with Spectrum. However, we are currently testing other peoples’ glass too in an attempt to locate more sources of working materials. Basically any glass will likely work.

    The pot was made of Spectrum too.

    We purchased recycled glass screened as fine as was easily available (thus we don’t know exactly the screen size or particle size). Recycled glass is used by ceramics folks to make low temperature glazes and thus is readily available.

    Particles don’t absolutely need to be at 400 mesh. If your materials are courser then you may need to change to a thicker layer when you spread powder.

    The change in formula was a result of work done by Grant to produce better parts. If you’re an engineer/scientist, then think “design of experiment” concepts, otherwise think really smart testing. Lower organics translates into lower shrink.

    Have you done any tests combining a non matrix material in with the clay or glass material? What I was wondering does this activated material adhere to other materials such as metal wire? Potters and glass artist have used metal wire, for example, as inclusions with the claybody or glass. At the 1325-1375 firing range copper or nichrome wire will work. On firings at cone o4- 10, nichrome wire would be a better choice.

    Thanks, Jeff

    Jeff, sorry we haven’t really tried any like this. If you think about the organic binder as behaving like white glue, then there should be adhesive effect on metal wire. Also, since the objects generally shrink during sintering, the non-matrix material should be locked in place by the surrounding body. One could just drill a hole and then put the wire in before sintering. Sorry we haven’t tried this.

    We have tried putting non-matrix things into the build by pausing each layer and adding material.
