No Amish community has faced 3D printing yet. But will.
Scenario
English client: 'Can you print a buggy part?' Amish craftsman: 'No. I'll MACHINE it. By hand.' Client: 'For $5 and 20 minutes?' Craftsman: 'For $50 and 3 hours.' Client: 'Why?' Craftsman: 'Because mine will last 20 years. Your printed one — 2.'
Philosophy
3D printing = technology that replaces craftsman. For Amish: craftsman = person with skill = community value. Replace craftsman with machine = kill skill = kill value = kill community. Answer will be: no.
