The article indirectly suggests that the sand mould isn't one-time use. Is this indeed the case?

  I think they will have been re-printing new sand molds for each casting.

This isn't an article. It's barely a company fluff piece. It has no more detail on what sounds like an interesting project than the title of the link.

Why is CSIRO, a well-regarded Australian Government research organization, doing this? For some rich collector? Making duplicates of broken or worn out parts is a standard industrial operation. Here's a laser scanning service that measures out parts.[1] Here's a mechanical coordinate measuring machine measuring out an engine block.[2] Here's a Kuka industrial robot machining a sand mold for a one-off job.[3] That's somewhat unusual, because you only get one part per sand mold. If you're making more than one, you first make a pattern, usually from wood, that's then packed with sand. Then you remove the pattern and pour in hot metal. The pattern has to be adjusted in size a bit to compensate for shrinkage as the metal cools. Standard foundry practice, centuries old. After casting, you do some finish machining on the surfaces that matter, and leave the rest as cast. There's commercial software for all this. Autodesk Moldflow, for example. This is not an R&D project. It's the sort of thing someone would do in a good manufacturing technology 2-year degree program. I've seen people do this kind of thing at TechShop, although in a smaller scale than an engine block.

  This is one of many projects that Lab22 is working on to further develop 3d scanning and manufacturing processes. Amongst other things, there's: - 3D printed medical implants: https://www.csiro.au/en/Research/MF/Areas/Metals/Lab22/Titanium-Heel https://www.csiro.au/en/Research/MF/Areas/Metals/Lab22/Titan... - 3D printed jet turbines: https://www.csiro.au/en/Research/MF/Areas/Metals/Lab22/3D-printed-jet-engine https://www.csiro.au/en/Research/MF/Areas/Metals/Lab22/3D-pr... - Oventus's new sleep apnea device: https://www.csiro.au/en/Research/MF/Areas/Metals/Lab22/Mouthguard https://www.csiro.au/en/Research/MF/Areas/Metals/Lab22/Mouth... And lots of other stuff. I'm working on a branding project for one of Lab22's projects, and thought I'd share this because it was semi-interesting.

    Do you have anything that you can share that goes beyond the surface-level detail of the links, and gets a bit more in to the meat of things?

      Not on the Delage, sorry. I'm just doing some web work for other stuff.

Jay Leno (serious car buff) has been doing this for years. I think he and many other car collectors realized the potential of 3D printing of obsolete parts when the cost came down enough to be affordable.

cool story, but > using traditional manufacturing methods was not an option. ...why?
