So I think that they are skipping the beta phase because they could probably fix most issues with production equipment with a 3D printer. Elon and SpaceX have a lot of experience with 3D printing rockets in titanium. if there is something that needs to be fixed fast they could just 3d print the metal parts. yes this would be expensive but if their 3D printers are precise enough to build rocket it can probably handle printing production equipment parts in steel...

The problem here is that 3D printing on this scale is not possible. SpaceX can do it making 8 engines per Dragon 2 but not for 500K cars per year.
Injection molding plastic is where it's at for parts that are not structural. The rest is stamped, cast and extruded steel and aluminum parts.

Trev, I said 3D print the parts for the production equipment...."the machine that builds the machine" could be fixed if issues arise by 3D printer parts for it...3D printing actual Model 3 parts would never work...but parts for factory equipment and tooling could be useful.

Think about it. A tool that makes a specific part of the Model 3 is making said part out of spec. Tesla finds the part or parts that need to be fixed and 3D prints them in a few days. QC issue fixed...

Sorry, I missed that part. The main reason you do 3D printing is to create more intricate parts that you can't easily build in the real world via conventional methods. In the case of the "Alien Dreadnaught" I think Tesla is mainly relying on proven robotics but used in areas that humans normally wouldn't for car assembly (wiring harness, cables, hoses, interior/exterior trim).

Those are the main areas they mentioned they want to reduce the amount of "assembly craft" which is a euphemism for "humans making judgement calls" on the Model 3 assembly line. Keep in mind, the first version at Fremont is not the end-game but only the start. Grohmann engineering is working on AD versions 1.0 and 2.0 for future factories.

I fail to see how this helps with issues present in production but not in beta. If two parts don't mesh, for example, you need to fix that in order to proceed with the build. For betas you adjust the parts or whatever, and then go fix the problem on the production line. For production, you fix the problem on the production line, and that adjusts the parts. [plus pass the fix back up the line to the maker of the parts].

Are 3D printed tool dies really a thing?

Thank you kindly.

@Topher , you are correct. 3D printed parts are neither strong nor durable, and they are very expensive.

They can CNC mill parts very, very quickly. 3D not necessary.

Much of what they can tweak is programming, like fastener torques and welding locations and travel speeds.

If they have to, they can add fasteners (e.g. two bolts instead of one), extra bushings/tape/pads to quiet extraneous rattles and squeaks, and in some unfortunate cases adhesive (not your first choice of a fix, because it's less serviceable and durable). And of course they can adjust quality inspections and rework procedures based on what they find as they start up the line.

I think Model 3 will have higher quality than previous builds, especially on things like seats. There were reported issues with leather coming unfastened, etc, that we shouldn't see at all on Model 3 now that vendor standards are higher.
