I have a related question.
Seeing how long it can take to get yourself registered in some provider companies for chemical products, I have come to imagine what it would take to have a central distribution hub that would register pre-orders, then make one big order to the chemicals provider under one single name.
This distribution hub would then dispatch the products uppon arrival to each rep-rapper.
The same applies for producing thermoplastic threads. If we could create a network of acquisition, recycling or production doubled by distribution hubs, it would make things easier.
Taking in account that base products will be heavier more complex and expensive to ship (ranging from 100 grams to up to several kilograms), this distribution system is still far ahead in the future, but it would be great to have once the project reaches a widespread interest.
