Accreditation for 3D machines

We are at the very early stages of developing plans for the introduction of 100 SME’s to print 3D parts for OEMs.

Quite a tall order I know, but feasible if every area plays a part.
I’m still unsure about the IATF requirements when it comes to 3D printing and how this all works when supplying OEMs. I couldn’t find this clause that you made reference to previously so perhaps you could send me the actual clause or the link directly to it? Essentially, I still need your support and guidance to make this work. Without IATF approval, the plans are futile. The plan is to

Create a minimum of 200 jobs in SA - SME’s to manufacture automotive parts for Electric Vehicles
Grow the economy using existing technology (3D printing) for the next generation of vehicles i.e. EV. I plan to develop the plans to set up a new purpose-built greenfield manufacturing plant where SME’s can come together to manufacture components for local and international OEMs specifically for EV’s  I need to work with OEMs to identify the components that are not critical safety items and can be printed using Additive Manufacturing.
Setting up a massive manufacturing site where each 3D printer receives requests from OEMs and they print them as per the orders ‘locally’.
So that's it in a nutshell. Anything you can do to assist me here I would really appreciate it.
The incentive for you is there will be the need for the IATF certificate. The question is, will we need accreditation for the plant OR for each product that is produced by the 3D machines?"
