A continuation of:

I did a bit more research and found out these kind of molecules are called dendrimers, derived from the Greek word for tree. They might look flat on paper but due to their branching shape most of them have a roughly sphere-like shape, or rather like a sea-urchin. So far all of the dendrimers I have seen are organic molecules (the consist mostly of carbon) which is great because with organic chemistry there are quite a number of tricks to construct them.

To make a dendrimer you need a few things, a solution, a core and the branches themselves. To actually make the dendrimer you can do two things. Put the core into the solution and keep building by continuously adding branches or you can first make a few complete branches and add the core in last so the complete branches attach to the core. In both cases the branches have to be made unreachtive on some places to make sure all braches are the same shape and size. I have not been able to find out what the pros and cons of both of these techniques are.
