Point-2 may not be correct. Like 3DP, the nozzle heads occupy a space
greater than their coverage - making it impossible to have the jets
overlapping. The heads will therefore index within this space. Small
components will take as long to build as large ones in this case, making it
inefficient and also making point-1 incorrect.

Could we also have the case where the seldom used nozzles at the outside
will become clogged and require purging - similar to my bubblejet printer
when I come home from my excessively long holidays?

Incidently, like last weeks recipe (which I tried and burnt), could we be
promoting our own urban myth? After all, there are plenty of guys in China
who can carve bars of soap. I used to do it myself until my mum stopped me.

Why not fly to Muratoa Atoll and have the holiday of your half life?
