Prewar workshop: Casting small parts in the workshop

I have had some very good results casting complex parts using 3D printed PLA and cooking the PLA out of the sand first. It seems to vaporise completely and leaves a very clean shape in the sand to fill with metal.
Making the best of new and old technologies.

Fred, you are right in that there are more ways to make the part. But since the original was a casting, i like to do it the same way. There's no such thing as a casting look.

Politi, the process was about 3hrs. But of that, half an hour was printing time and another half hour to warm up the furnace. I can do other things in that time. Machining with this part was of course very easy but is normally the most time consuming.

You are obviously proficient in CAD, use of the 3D printer, and the process that followed. What was the total time you invested to make the part(without installation)?

I've done a lot of casting but a part like this is much easier to make in 2 parts and silver solder them together. Easy to machine each part and thread the neck and then solder together.

These days a part like that can be 3D printed right in metal.
