It would be so difficult to produce cellular phones and cars that printing homes may turn out to be craziness of the highest kind. For producing cellular phones or laptops the printing community either needs to have micro-Intel like facility in their community or Intel needs to provide chips and their whole designs to them. Unless and until a striking breakthrough in automation and robotics takes place this may not be at all possible.
True, if there is a shortage of labor in any society or it does not like immigrant labors, then those people can use this technology for some purpose. But manufacturing branded products inside homes or in communities may require changes in all copyright laws and patents. It could restructure the whole international treaties and global governance.
The fact is that the world is becoming more and more solipsistic and people would like to bring the biggest possible world inside their homes. But individual consumers can not become those big producers in any conceivable time to come. The argument of manufacturing jobs moving back to the West is like showing oversensitivity. What it would mean is the increase in disparities, inequalities and asymmetries between the Westerners as a group and the non-Westerners.
Americans would become superhuman one day, should the idea of community-manufacturing be realized at a large scale. The Democrats would be defeated and Republicans would dominate for many decades to come even though the sexual pervertness, infidelity and homosexuality would increase. Democrats are more required when there is need to convert others; that would decrease because of the political impact of this technology.
The idea to produce oneself in such a human-surplus and capital-deficit planet would be considered a kind of hatred for others; homophobia of the Whites in the age of Angloeurocene disrupting the many commonalities of the Anthropocene. But if it is possible it will happen; nobody would wait for others. The race to dominate would end with all probable getting converted into Westernism.
If the earth continues to grow, then the time will any way come when economic betterment and interests of individuals and nation-states will matter over their ideologies. But for that the West and the BRICS would have to grow simultaneously implying a balance between Western primary and derivative powers and continuous updating of the BRICS demographic potentials with huge advances in renewable and recyclable capabilities. It would require equal commitment to what the West calls as universal values; a difficult proposition considering the growing conflicts among the people.
