Im positive that this is a cross over medium, cnc steel printers are already using the same tech, built on a foundation of cnc programing widely used in metal fabrication and cnc machines. If i can get a grasp of the tech i would build a fluxcore printer, because why not!?
But as a prototyping medium, Gcode tutor etc it is an indispensable part of my shop now. If I can only get time to perform some lost wax casting...........

Here is my ford boy making a really fancy aluminium part by casting from 3D printed lost wax process. Pretty neat stuff. My spouse was asking why did he need to fool around with all that piping through the sand. Why not just fill up the mold with aluminium to the top? I mean just fill the white investment cast mold?

I tried using some plaster and sand for a casting once after drying in the kiln they become quite brittle. I used a printed mold and that microwaveable material from PMS Hobbies you just heat it and pour giving you a rubbery pattern although it is flexible but could be strengthened with wire in the cavity or cooled in the fridge.

Are we talking about using the centrifuge type of casting? I have been toying with the idea of building one for my Sons wife and Daughter.
3D printed casting sand. Now we're talking. Eliminate the plastic/wax middleman.
I should send in a CAD file to get a finished aluminum all-in cost guestimate. Anybody heard of this technology?

Can anyone show their creations on a 3D printer
I mostly print parts as models for sand casting but have also replaced parts on my equipment including the pulleys on my cnc mill

42 hours. Allot of time was spent printing the supports that were needed for the top. I think I could have printed it upside-down and saved 10 hours but then it wouldn't look as nice from the front.

So since I have lots of people that have printers is this is a good thread to ask for suggestions about a FDM printer purchase? I was thinking about more basic model up to say $500 but fully functional, not a kit, just something that will do some prototyping and look decent. There seems to be a lot of choices - is there a trustworthy site comparing the models?
My research of resin vs. FDM show that resin is around 3x more expensive to run then FDM but in the same printer class produces a bit better resolution. Through the main "shine" area is use of resin that is "special" - for example - one that is resistant to heat.
