3-D Printing re:Tesla


With "3D Printing/Sintering" (SLS/SLM)

How might this impact profitability/production of...multi-vehicle/project lines; "in parallel;" with the same equipment -- running a different file.


Oh...and wow graphene re:all.

Printed metals lack structural strength still, I believe. Not sure if continuous sheets of graphene are printable.

cliffmccormick - Was there meant to be a link with post?

Anyone interested in 3D printed Graphene should check out this company. Here is a chance for investors to get in on the ground floor.

For the strengths and properties of 3D printed materials you should check out WithIn lad. They make software for optimizing 3D printed parts.

There are 3D printing processes that can certainly produce highly durable parts. However, they, like all 3D printing processes, are extremely expensive on a per-part basis compared with standard mass-production processes. The more durable the parts, generally the more expensive. This makes it viable for low-volume production of 1's and 10's quantity but once quantities exceed 100 or more, it is generally worth going to different processes. 3D printing, of course, is then a good way to do prototypes and make molds for high-volume manufacturing.
I would be very surprised of Tesla doesn't use 3D printing for much of their prototyping.

3-D printing - Cheapest for qty of 1
Machining - Middle cost for small or large qty
Custom molding or casting - Cheapest for large qty, but dies are expensive so design has to be stable

Companies will pick the best cost optimization for their business.

One very important ability of 3D printing that will drive the industry and eventually will drive the cost done is the ability of additive manufacturing to produce geometry which is quite literally impossible to be fabricated any other way. A perfect example is a conceptual heat exchanger being designed by WithIn Lab and fabricated using Direct Metal Laser Sintering by EOS

SpaceX is already flying 3D printed parts.
A year ago, they flew a printed fuel valve on one engine of an F9 launch.
They also print the Super Draco engines. Test videos available on the SpaceX site.
Practically every aerospace company has functional printed parts.

By the way, the valve that SpaceX printed was printed in 2 days verses 2 months for casting the old way.

Awesome contributions!

Thanks for the info.

@rlwrw, but that is the point mentioned by Earl&Nagin and Don S. Aerospace companies produce those parts on a scale of "several", not on a scale of 100,000.

GE is using some very specialized 3-D printing to make turbine blades for their LEAP jet engine. The process uses an electron gun instead of the more traditional laser. The new process allows manufacture of of the blades out of a new material, titanium aluminum (TiAl), that only weighs about half compared to the common nickel steel alloys used previously.

I haven't found any published costs comparing this new TiAl cost to the old method, but I doubt development of a new process is going to be cheap. For manufacture of jet engines, cost cannot be totally ignored, but it isn't that high on the priority list. It will be a while before we see high volume car parts using this technology.

Additive manufacturing (AM) is one of the hottest areas in parts fabrication. AM has moved beyond it's initial role as a prototyping tool to a process that can build finished parts. AM technologies like fused deposition modeling (FDM), were able from their beginnings to accurately form complex, three-dimensional parts directly, without tooling or additional manual labor. But those early stages of the technology came with technical challenges that - particularly in the composites industry - limited their utility. Early AM devices used low-end, unreinforced commodity thermoplastics and there build areas were small which extremely limited part size. It took early adopters and enthusiasts of the new technology to show the rest of the world the possibilities that AM afforded. Not only could AM produce easily duplicate parts with specified dimensions and tolerances,they could produce parts and shapes that were impossible to produce using molds or other techniques, indeed they were AM can produce shape that are impossible to create any other way. In those beginning years AM afforded no viable alternative to molders of high-performance composites. In recent years however 3D printers have evolved to use materials with a wider ranger of properties from soft rubbers to long strand carbon fiber, kevlar, and fiber glass reinforce nylon.

One new company building these printers is MarkForged

Replication. That's the sort of Additive Manufacturing I am looking forward to seeing in reality.

I found this interesting. Lockheed Martin is experimenting with using industrial robots as 3D printers. I could easily imagine four automotive robots working together. Each printing one quarter of a car.
