    Thank you for your reply, Bin. I see. I thought that you used not the 3D-printed machine but the 3D-cutting machine. I am sorry for my misunderstanding.

    Hi Tomoo,
    For pre-gasketed octahedral pressure medium, we use the 3D-printed semi-injection mold made of 8 cubes with edge shaped for the faces of the octahedron and the gasket. After molding, all the cubes can be taken away from the octahedron carefully. The cubes will be greased for easy removal.

    If I understand correctly, you manufacture pressure media using the modeling machine. However, how can the 2.5D modeling machine manufacture the lower sides of the pressure media?

    Dear Prof. Katsura,
    Thank you very much for your question. It is the difficulty we are facing now that we don't know the stoke displacement data in many diffierent labs. So we need to discuss it very carefully. However, because of the similarity of stoke data between GIG and GRC, we believe the phenomenon we reported is common in many labs, and the gasket deformation in Kawai type and Osugi type must be deffierent. For your question, the increasing strokes with increasing temperature means the gasket deformation effect is stronger than the thermal expantion effect in your Osugi type press. The reason may be softer gaskets or better heat transpiration.

    About the difference in stroke upon heating between the Kawai and Osugi guide blocks. In my experience, the strokes also increase with increasing temperature, even in Osugi guide blocks, and rarely seen the stroke increase at any temperature range.
