3D Printers
- 2 people have reserved printers
- We currently have 2-3 printers ready for printing parts, so we need 6 more minimum.
- We have 14 people registered. It makes most sense to build 7 printers in the first 4 days - via a perfected workflow.
- If we have 10 printers printing - we can print parts for the 2" universal Axis. Basic ergonomics:
- Now the question is can we print a sufficient number of parts for 7 3D Printers
- Start with D3D v19.06 BOM, then inventory - and start printing.
