A practically perfect vacuum (PPV) is needed by gem-gum technology since the the force applying mechanosynthesis that is synthesizing the crystolecules that form the basis of gem-gum technology needs it.

Currently impossible because ...

With current day technology (2021) it is not at all possible to reach a prefect vacuum. Limiting factors are:

• gasses (like water vapour) adsorb onto surfaces when vented (and spoil the vacuum later)
• gasses diffuse into material (especially at grain boundaries)
• large vessel sizes

Becoming possible because ...

In gem-gum technology all these limitations are lifted.

• very small vessel sized are possible (statistically ore likely that there is not a single atom in one vessel)
• flawless single crystal walls in those nanoscale chambers have no grain boundaries
• hydrogen passivated diamond chamber walls do not adsorb gasses well

Additionally strong open radical bond free gas molecule getter surfaces can be integrated.

(wiki-TODO: add a sketch about how small vessel size makes PPV in a vessel more likely)

Chicken egg problem

That leaves the problem of cyclic dependency: gem-gum technology

• is capable of creating PPV but it also
• needs PPV to in its nanofactory manufacturing devices

Interesting off-topic question

Can a part of the probability density of a fullyquantum mechanically delocalized gas molecule be transported away by atomically tight positive displacement mechanisms?

How much decoherence is there by interaction with walls at room temperature?
