There is lot of subjects considering for further studies, to find right size of support teeth, optimized thicknesses for solid and criss-cross beam, the maximum x-spacing, the length for non-supported edge offset and what is the maximum ratio between the width and length of criss-cross beam. After these parameters have been found for plane surface, like plate or cube, it should be studied how criss-cross supports will behave for inclined surface. Ball could be used as geometry for an inclined surface, because ball has variable angle so there is also possibility to create supports for different angles for chamber.
Firstly it should be found suitable parameters for teeth. Because there were many supports that were failed when the part was started to build. Maybe the versions that failed at that point would have been manufactured, if there would have been stronger and larger size of teeth. After the optimized size and other parameters for teeth have been found, it is important to find the maximum length of non-supported edge in view of material savings. This parameter is kind of part of teeth parameters, because the size of teeth should be proportioned to it. It is also possible that the non-supported edge offset must be zero, to prevent thermal bending.
Once the suitable parameters are found, next step should be to start sawing the parts off the building plate and evaluate their surface quality and how strongly the parts are attached to support structures. This is important before criss-cross support structures are taken to use of industry, because there the post processing time is very important to get as quick as possible.
The ideal situation would be if the part could be loosed from support only with pliers. But to get this far there is a long road ahead.
