We are working one of our glass suppliers to find “just the right” glass powder.   The real issue is what exactly is the best powder size distribution.   Please understand that it could take a quite a few attempts to get this issue “right”.     They are making some samples and we are testing these powders as they become available (This is a great form of engagement.  We are working as a team).

Printing on the new powder (results are good)!

Printing on the new powder (results are good)!

This is perhaps one of the best printing powders that we have seen in our lab.   Also, it depowders nicely.   Overall: +++++

Here’s one of our sample surfaces created in Mathematica ™.  It was exported as an STL file.  Then, it was checked with Meshlab.   Finally, we did some adjustments and checks with Rhino.   Again, back into Meshlab.    Lastly, we sent it to the 3DP and then kiln firing.

    Katie,
    During printing the interlocking pieces are supported by unbound powder. After, kiln firing it is a fused friction fit.

    Sorry, we remove links to company web sites as we are a public university. We are allowed to present companies who are engaged with us. If you work for O then, perhaps you should just contact us, and ask us how to play. O would be welcome.

    Are the measurement units in your recipes weight or volume?

    Paul, great question, thanks! All of the units are weight.

    Any recommendations for those of us wanting to experiment?

    I’m trying to work with a few of your recipes, but I can’t even find the Baker’s Special Sugar, much less powdered glass!

    I shall continue to search until I find just the right solution!

    That looks great. Has it been used for shapeways parts yet?

    We’d be happy to help provide this to the market along with our other ceramic & sand casting media. If there are o

    Well, it looks like something happened when I hit “post last time”.

    The short form of my post was this:

    Viridis3D has just acquired several zprinter310s. In addition to commercializing our own sand casting media (no-smoke steel castings, anybody?) and alumina based ceramics, we will be evaluating (quantifying) some of the open 3DP formulas from various sources. We are hoping that being able to compare the stats on various powders will help users decide which formulas they want to use. In addition, it should highlight areas for more projects.

    For those who are interested, but not set up to make their own powders, we can make open formulas (that don’t infringe on any granted patents) at very affordable rates.Viridis3D will return a portion of the sales back to programs that provide new recipes.
