	~~{{wikitodo\| the below makes absolutely no sense - resolve that}}~~		This requires [[positionally atomically precise]] [[covalent seamless welding]] of <br>
			fully unpassivated [[crystolecule fragments]] of space filling shape. <br>

	With ~~an early transition to an air filled environment the creation of monolithic structures becomes harder or even impossible~~. ~~But:~~ <br>		With irreversible strong bonding on first contact self centering is not a viable option. <br>
	* Such structures provide only minor and questionable advantage in absolute tensile strengths. <br>Form closure fir tree interfaces can preserve a goof deal of ~~the absolute tensile strength bulk material and provide spots stopping cracks.~~		First contact must be atomically precise without the help of any self-centering guidance.
	* Such structures are non-~~modular and non-reusable, so not very desirable anyway~~.

	~~Only for certain very peculiar products~~ (~~including e~~.g. a ~~macroscopic~~ single crystals) it ~~would be necessary~~ to ~~defer product expulsion to higher assembly levels~~. <br>		With growing size of crystolecule blocks (super-large [[crystolecule fragments]]) the <br>
	[[~~diamondoid metamaterial\|Metamaterials~~]] ~~from passivated~~ [[~~microcomponents~~]] ~~should be capable of fulfilling almost all our needs though.~~ <br>		vulnerability to large amplitude vibrations from external mechanical shocks increases. <br>
	[[~~Microcomponent~~]] ~~expulsion marks a clear line preventing inter~~-~~mixture between the second and the third assembly level~~.		Thus aligning blocks to atomic precision gets increasingly difficult/risky with growing size. <br>
			And going far up in a convergent assembly hierarchy is actually counter-productive. <br>
			So for the production of large single crystals the earlier the last assembly level is the better it is. <br>
			With an early transition to an air filled environment the creation of monolithic structures becomes easier.

			Vacuum quality becomes an issue though. <br>
			Creating and maintaining a [[practically perfect vacuum]] across a macroscopic volume is likely <br>
			more challenging than for just micro-chambers (which suffice for all other applications beside macroscopic single crystals). <br>
			While macroscopic open volumes of [[PPV]] are completely impossible with today's UHV technology, <br>
			macroscopic open volumes of [[PPV]] should be possible with [[gem-gum technology]] though.

			If not, then complex tricks with local sealing need to be pulled.
