Ask HN: What are some low entry manufacturing possibilities?
What small business can one start with relatively low initial investment (e.g 2000-20.000 $) and low domain specific knowledge, but decent general engineering knowledge ? I&#x27;m thinking specialized production machinery, e.g CNC, 3D printer, etc. to  mass produce &#x2F; custom produce common &#x2F; custom tools &#x2F; products of relative simplicity but high enough demand (e.g cotton swabs, PCBs, as some examples that come to mind).<p>On a more philosophical note, I observe that:
- we are flooded by products, information, ads, etc, a seemingly abundance of everything.
- production becomes more centralized (due to complexity)
- individuals are more and more limited in their ability to self sustain (consequence of the above)
- anxiety, depression, agression tends to increase (because of above). More so now, amplified by current pandemic and restrictions. Also, as a sidenote, the pandemic showed as we are not optimally organized (too centralized everything as apposed to more geographically and socially distributed)<p>In that note, what self sustainable businesses would you think are good to exist more of, to the benefit of the individual and the society as a whole? And what are your thoughts and advices on getting there, one step at a time?
