2 sampels for 3D prints of casting - do you know more interessting sampels?
Not at the top of my topic tracking but more and more increasingly interesting do of more and more upcoming developments in 3D printing.

It is called lost wax/lost PLA casting and not really anything new.
And the other way around, printing a mould to be filled isn’t new either.
In terms of ideas - almost anything that can be cast the traditional way can be done with printed negatives/moulds…
If you don’t know how to cast resins and metals than using 3D printing for it won’t help much - just saying.

It will certainly be a world of its own.
That they cam down with soft materials down to shore A35 with higher heat resistance, and that they also use centrifugal casting for smaller metal parts - interesting.
Until now, I only ever know “chill” casting, if not even sang casting. The centrifugal casing for piping work only - it’s interesting how they work on it piece by piece. The problems with sand and “chill” casting are well known: lower load values, higher protection inclusions, etc. (becouse “chill” - I don`t even know if it the right englisch word for the procedure)
The chosen path, interesting - always amazed at how smart people are. Well, maybe for a long time, but there is a lot to see an it never stops 
Burnout is a problem with many plastics. So if you use the plastic for lost-wax style casting, you end up with carbonized defects in the casting from the plastic that didn’t completely burn off. For SLA type printers, they make special resins that are designed to burn off cleanly and completely, specifically for casting. Very popular with jewelry makers.
For larger castings, though, I suppose FDM could work too.

Apparently PVB works well for this.

They make FDM printers that print with wax filament for this purpose. Solidscape Wax Printer is one of these printers. No price listed on the website, so I am guessing that they are expensive.

I was thinking more in terms of a consumer-grade 3D printer.

Heavy but interesting information, certainly a world of its own:
A German site with an English subpage with an interessting Table of Vacum casting matirials, so some of them also printable:
