Technology is further evolving. This might be the solution to “print” rare spare parts in the future.

Unlike previously, this is not working with powder/laser/thermal... This is more like extreme plating with far lower cost and better quality.

Wonder how long it would take to print a 72 911 shell

This is already happening quite a bit for rare race cars. It’s very cool tech and can print parts that used to require casting. Inconel, titanium, etc.

If you do Instagram follow BBI autosport and you can see some of the parts they are 3D printing for later generation Porsche’s.

I worked on an interesting trial about a year ago I involving Markforged, out of Boston. In speaking with the founder of the company, I learned they have significant investment from Porsche. He talked about how they develop parts for the racing program. Amazing how it has sped up development.

Copper, nickel, silver, gold, tin. These are all electroplatable materials. They are also commonly used in electrical connectors. As stated in the article, copper is at an advantage with this process, because it is difficult to process copper with other additive metal fusion techniques. Thus this is ideally suited to electrical connector prototyping. Also, current metal fusion processes have severe limitations on minimum wall thickness and resolution. Typical minimum wall thicknesses are at around 1mm or .040". With increasing data rates electrical connector sizes must get smaller, and their features must be more accurately controlled to assure the proper impedance profiles. This looks like a very promising technology.
