I find smoothing the print before hand to be very effective in reducing post processing like sanding while making it look much nice after the cast. It could affect ceramic adhesion possibly though? Awesome work.

Most people with a 3D printer end up with lots of semi strong models to use and show people. I bet you have very few prints but loads of cast parts. Good work👍

awesome video.. thanx for sharing.

Awesome job!!!👍

Beautiful!!

Super cool! Nice job

That's wicked cool

Glad I found this video. I also built the fire-keg and have been doing some casting. I recently started using investment plaster. It works quite well, but I like the slurry method better. I knew about it, I just didn't know you could "backyard" it. I'm shopping R&R stuff now! Upfront costs are higher than investment, but you don't have to construct a flask. Great for bigger items. Although, I need a deeper kiln!

hi sir...im from Malaysia...wow...that so creative..i want make one same like u do...thanks sir for give me idea..

Damn nice done i have bin working in a casting company it was the most beautiful work i have ever had......i wish i could turn back the time .we also did the lostwax technic and i was caster and welder of bronze castings and somthimes i did the sandblasting and that was not no nice because i was in the sandblasting room and some status where bigger than me and way bigger wish you luck and may the force be with you

Awesome 3d printing design of the Stormtrooper...will you be making more of star wars or something else next keep. It up amazing job

Badass

Do you prefer using the ceramic slurry vs plaster? Great project!

wow!!!

man, you have all the cool toys! i saw in another video where you use a filler to smooth over the print layers on the PLA model, so i'd be interested in seeing a comparison video of how you do it now as opposed to then....

Well done - like your set up. Can you do it in bronze? I guess the only thing I was concerned about was that you cast the object solid, but maybe that's fine for Aluminium.

Wow

AWESOME POUR! What Company made your Kiln? And where did you find the pouring tongs?

tip for avoiding pitting and cold shuts, is to heat the ceramic shell - to basically glowing red before filling it with metal. :)

For once I see someone actually using the safety equipment they should have on while pouring molten metal good job young man

@@robinson-foundry One thing that could cause porosity is how long the pour sprue is without tapering, when the aluminum hits the bottom of the sprue it creates a lot of turbulence. Its similar to how if you dump water into a cup from high up it has a lot of bubbles. If the sprue tapers to be thinner near the bottom, it can reduce turbulence and porosity.

I've been binging your videos, and I was wondering where you get all of your material? Thanks!

Dip it in hot molten wax before making the mould so it hides layer lines?

Why not use ABS and acetone smoothing before casting to get rid of the layer lines?

Is the slurry kiln the best way. That equipment is quite a bit more expensive.

Another commenter mentioned that people are being too critical here. I read all of the comments and I'm not seeing it, so I sure hope my own OP didn't come off as some kind of snarky backhanded compliment or something. This casting looks great as I said, very impressive even. I love how you left the skull with the sandblasted texture and polished his helmet (I see it... I'm leaving it😀). But that shrink just has to be *somewhere*, with a casting that thick and comparatively small reservoirs to feed it... My guess is that the relatively cool shell must have frozen the melt against itelself almost immediately, and chased that shrink into the interior of the casting where nobody will ever have to see it... The perfect place for it! If decorative items can be cast solid without visible shrink that way, instead of having to saw off and fettle away big feeders, while also avoiding having to mess around with cores and maybe chaplets and welding and all that other complicated crap that comes along with making hollow castings, that is a super great thing to know! Makes me wonder if the shell is porous to get away with casting something like this without needing the big vent on top, or with maybe just a few really thin wax or PLA wires for vents...

@@tobhomott I appreciate all of the nice comments and constructive criticism. I definitely didn't take your comment as snarky in the slightest. Thank you! As for the shrinkage. You' re absolutely right that this should have had visible shrinkage. I originally planned to cast this in bronze but didnt realize it would be around 15lbs. Reluctantly I chose to use aluminum, knowing I would encounter shrinkage. Fortunately, because I had extra metal which I poured into a bowl, when I noticed the metal shrinking down into the casting from the vent I used a spoon to refill it. I did this off camera because I didnt have time to set it up. Im amazed it worked. To tell you the truth I really didnt add that much.

You need a rattle gun for knock off, would eliminate some sand blasting.

hey seth, that looks hot, like maybe 1700 you might try cooler to get less shrinkage and porosity, 1350-1400 which is more like a pink but not orange color on the metal.

Good job man.. You can probably shave off a couple of layers of shell if you wrap with wire after layer 3. It's not hard to remove on breakout. The shell just crumbles around it. I notice your surface isn't what it could be. What grain size silica are you using on the first 2 coats? I recommend something pretty fine and then back it up with course stuff to build up strength. Good idea with the pan during "dewax", I bet that's some stinky shit!

Thanks man! I’ve learned a lot from your videos. So you’re saying coat three times and then wrap it wire and then continue to coat a few more times? I went with 10 coats because I really didn’t want the shell cracking during burnout. I’m using a very fine silica sand for the first two coats and coarser silica sand for the rest. I followed what you said “suger and salt”. I did a large lost pla bronze sculpture with the exact same process however the bronze is incredibly detailed, almost as if it was printed in bronze. So I don’t think it’s an grain size issue. Someone told me that my pour was way to hot.

@@robinson-foundry Exactly! I learned this trick from Berry Luke builds here on YT. It's especially helpful with thin edges to keep the pressure of the metal from blowing out shell. This also works on that plastic pooh you are melting out. Salt, then sugar! Well done! You are probably right and it was probably the temp of the aluminum. I haven't done shell with aluminum in a long time. Seems to me, preheating the shell isn't that important with aluminum and R&R told me on the phone once, just 3-400 degrees preheat on the shell was plenty. With really thick stuff like your skull, it needed to be just completely melted. Same for bronze, I always pour thinner stuff first so it travels through the mold and the thicker stuff I pour cooler. I get a better finish and less cleanup work is needed. I'm impressed you poured that fat skull solid and didn't suffer any weird shrink issues. That's a testament to how good shell is. David at thehomefoundry yt channel does some of this lost pla stuff and I know he runs shittons of layers too. So 9 not reinforced isn't out of the question. I bet that thing was HEAVY!
