You can see my new 25 m², 2 room mini mold workshop in the photos. I’m planning to add a ventilation system,+2x printers 1xsmall thermoforming vacuum machine and 40x40 cm vibration table.

But I’m honestly a bit worried about how to fit everything into such a small space efficiently.

Any suggestions, layout ideas, or criticisms are welcome. I’m open to feedback on how to organize it better or if this setup is even realistic for a space this size.

I’m developing a GFRC mix for decorative pots/vases.It includes quartz sand, quartz powder, calcite, silica fume, AR glass fiber, PCE, acrylic latex, etc.Do you think the calcite content is too high for surface quality and long-term durability? What would you change in this mix?

Hello, I am planning to make silicone molds with a hardness range of 20 to 60 Shore, with volumes of up to 6 L. However, the vacuum chamber I am considering buying unfortunately has a capacity of only 15 L.

Would it be possible to gradually increase and decrease the vacuum in order to control the expansion and pressure difference while still maintaining the material quality?

As far as I have heard, this method may cause more bubbles, but this does not seem very logical to me because I will not be completely releasing the vacuum; I will only be changing the pressure difference gradually and without being too aggressive.

I do not have the option to use brush application for the models I will be producing.

Casting in two separate stages also does not seem very practical to me, because I think surface bubbles at the end of each pour would be inevitable, and therefore I believe deformation may occur along the line where the two stages meet.

Thanks in advance.
