Thanks :)


Castings are only as rough as the sloppiness of the operator.
This one was done in 125 grit sand

3D printed patterns need to have the surface smoothed out. Most are using hi-build auto body primer/surfacers
then a quick coat of something smooth and shiny.
Otherwise, it wont come out of the sand mold well.

:shock: That's beautiful! Someone has been doing their homework. I hope to rise to that level one day.

Excellent work there. I watched the whole process years ago on how to make the molds etc and it looks like a lot of fun. I also play around with some 3D stuff and have the software (or some that will make the files to print), and some skill, just never bought a 3D printer. I know the #D printers are really slow so that is one reason I have avoided them. What brand/model printer do you have and do you have any recommendations on the purchase of one??
Thanks ;)

Nice looking casting well done! Did you build the 3d model with a draft on the edges? I have also heard of smoothing the printed object with acetone vapour I've never tryed it though. The main thing with 3d printing is how big of a build area you have to work with alot of the times wood is easyer.

I do not have a 3D printer.
I make all my patterns old school- ie wood

and yes, there has to be draft or you will break the mold extracting the pattern

First heat today, melted down some scrap into muffins. Worked great until the wind kicked up really bad and played hell with the draft on my burner but all in all I learned a few things, I didn't have to be rushed to the emergency room and I didn't burn down my shop. Success. Now to learn how to make patterns and cast.

:lol: I went and bought a couple. I was eyeballing hers but thought better of it, plus they were aluminum...that would have been bad. I'm pretty happy with it. The guy I made it for is fabbing the prototype part he wants made and then the hard part will be learning how to make the mold and cast. Looking forward to it.

Fresh out of the mold and then cleaned up to go to machining. This is a custom pool table corner. I supplied the rough core and now my friend is going to machine it down to the final rendering to make it a bit easier to cast and easy to clean up on the mill. For my first casting, I am pretty proud of it. It's not as easy as it looks.
