Casting Aluminum for the Home from a Simple 3D Print 

I don't know. Those are the sorts of simple mistakes probably a majority of interested amateurs make and curse the heavens over. It's nice to have a video targeted to people nee to the idea of casting being given a solid practical explanation of just how important that step is.

I learned from it. I was amazed at how hard the zero draft part was to get out. Too often I try to get away with zero draft and probably shouldn’t!

@@Grunblau can i cast the same way but instead if aluminium with steel and titanium ?

I'm new to all this I greatly appreciated it as much as I can learn before I try anything the better

Love seeing people like this in the world makes me feelgood

Its pretty standard. Depends on the quality of layer height.

I've seen prints that have a slight checkered texture. Must have been on a low quality setting.

@@Cloakfiend It's pretty bad lmao

IKR? Now I know that a 3d print can be cleaned to that level of finish and how to do it. Thanks Brian!

​@@bryansummers3219 When I first saw it after he put the glue on I thought. "ok that looks hacky as hell..." After he sanding it and put the finish on, I was thinking "OMG, that looks like something that came out of our finish room!" I haven't seen finish that good without slathering it in bondo and drowning it in paint. Wonder how well it holds up. I'm going to have to give it a shot now.

Thank you! I miss my own ‘long form’ attention span…. Old RU-vid was best when it felt like we sat down to a meal. Today’s content feels more and more like I’m eating rice cakes. Tiny bit of flavor on top, but mostly just puffed air…

It's because you weren't interrupted by the mid-rolls, ads, words from his sponsor and all the crap the scam boss running youtube makes you endure.

Thank you!

@@Grunblau My friend... You finished cast wasn't smooth because you didn't press the sand... That's why!!! Got to tap it with a piece of wood while you put sand on the mold...

I thought the same thing. Love how you mixed the voiceover. Reminds me of vintage Disney nature films.

It sounds like speech to text software.

I always thought that was Dick Proenneke's voice but it's actually Bob Swerer's. I believe there are three documentaries around Dick and his cabin if you haven't seen them yet, they're worth a watch (I believe some stuff is reused but it's been a while so my memory might be failing me).

Excuse me, not his cabin, his cleverly stacked firewood pile. Building a cabin there is illegal.

Why would he? He was shurely in it

Thank you! I think a lot of people will start looking into PLA investment casting. Much like my monkey video. This creates a very nice cast.

Thank you! I have been a university teacher on and off for the last years…

I keep telling myself that I can get away with ignoring draft. This demo convinced me otherwise!

@@Grunblau You can ignore draft if you go with investment casting.

Polycast is a 3D printing filament developed for investment casting.

@@Grunblau maaaaaybe now we can see how you finished up that domino box... hint hint

Glad to hear! Thank you for posting this…

Can we see your guitars/parts please 😍

I play guitar i want to see your parts.

@@user-be9ey4jb3c Does that pickup line work well for you?

@@l00kns33 what pickup line?

I miss the Old RU-vid too! Thanks

Yeah haven't seen a video in years it feels like, but always stay subbed in case one comes along.

God has said in the Quran: { O mankind, worship your Lord, who created you and those before you, that you may become righteous - ( 2:21 ) [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 ) And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 ) But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 ) And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 ) Quran

Thank you! I am glad you enjoyed it!

I'm not interesting about casting aluminum or other things on this channel but I'm impressed this style. I came to make exactly this comment and saw yours. This video remind me old BBC educational VHS series.

Today is a good day to fight!

That was the seed that sprouted this video!

Thanks. I try to keep things moving especially now when you have to compete with 10 second videos on Reels and Tik-Toc…

YESHUA GOD ALMIGHTY is perfect in engineering isn't HE?

If you sit on that fence long enough, grab one of those induction furnaces for like $700 - they are insane... :p

@@Napkinholdin got a link? Or brand?

@@SeanHodgins let me get back to you later today (like 12 hours) I have a link and some info from when I was searching. I ended up with a great piece of equipment and another RU-vidr explains how to easily switch it from a 120v to 240v if that sort of thing is needed.

Make a list of steps, and then do the first one

I do as well, but legalities

Indeed!

that's what the ATF said

Thank you very much for your comment!

I am a meat popsicle…

Yes 👏🏼… I ❤️ his videos. I know it’s a lot of work… and he probably has a day job… but I’d love to see more. Hey RU-vid… pay him more so he can quit the day job and focus on producing more content‼️ 😊

This

I 3D print and can confirm that acetone washing can be used on ABS but that’s about it in my personal experience. It’s just as easy to print with PLA and do a resin wash over the print with little sanding at the end.

You can also use plb and isopropyl alcohol

@@TAH3DGeek1994 can you please do a video detailing more specifically how you get such smooth prints!

@@rainydaytoast1490 I plan on doing it eventually and starting another channel solely for it but I can’t at the moment as I have a very busy home life. Once I have some more time to spare it’s something that will be done. For now I would recommend visiting uncle jessy on here as he has some amazing videos on it

The smoothing is pretty pointless in this case ... the metal parts need be finished anyways and it won't make a huge difference removing the plastic from the mold

I am glad you liked it! You might find my monkey casting video a good time, too :)

Thanks for the comment! Look for the my monkey cast video. I think that is the future of the home foundry.

btw it's the same idea for vacuum forming, slope make the day for removing that... tho it might not save it from going wonky due to the plastic..

You bet! Have a great weekend…

Thanks! Learned that from a pen turner…. I was amazed at how nice the finish ended up!

You bet! Hope you come back and check out some of my other videos!

I miss the old, long form RU-vid videos where most people spent more than a couple days on a project…

Is there a time that would work best for you? :)

@@Grunblau anytime is perfect time 😄

One of the two channels that I have notifications set for. The other is This Old Tony.

@@Grunblau Every day ;). Welcome back

@@The.Talent exactly.

This is correct.

But is it made in Australia ?

@@kymlardnerofficial it sure is! I'm not sure what percentage of ingredients are Australian, but they're still manufactured in Sydney at least.

A visit to Darrell Lea was a must any I time I went to the city in Melbourne as a kid.

You're ignoring the fact that what produced those artifacts is not the 3D printed part, but the sand.

@@alejandroperez5368 ... 1:13 ...

@@alejandroperez5368 he’s talking of the printing artefacts. Which the CA glue is meant to smooth. Not the casting artefacts.

@@alejandroperez5368 you ignored the fact that he had to smooth the 3D part to get a smooth surface within his mould

Yeah lol but good for learning

The aluminum is beautiful, but I agree, the 3d printed part was also very nice once he filled with ca glue, sanded and applied the finish. I learned a. Nice way to finish off some 3d printed parts!

@@mikemorrison377 could have hit it with some "aluminum" spray paint and a coat of clear and had a very nice product in less time

I might post the 3D model on the website with a modified back for just that reason…

I also wish there were more ‘in depth’ channels on YT… I would rather see people post once a month than once a week, but RU-vid rewards more superficial content. Stay strong and resist and I will too!

I thought "Designer Women's Shoe Heel"

Thank you for your comments! I try to make the subject as approachable as possible…

For what it is worth; The smooth surface of the printed part is done for achieving a clean release between the plug and the sand mold. He did not press the sand that hard, because he wanted it to act as an air vent all over the surface. If he had made the mold in a material that didn't provide such good venting, he would have to make venting gates. (With his orientation of the cavity, he would need a vent at each finger. He could turn it upside down with the sprue on the other half, and manage with one single vent, but I'm sure he had his reason for the way he did it) . Anyway, whatever of method, he would have to polish the part afterwards. Removing the first rough surface goes quickly. It's the finer grid who takes most time and effort, and that work will be the same at each method.

I allways use a strainer for the first layer of sand. And i use long cocktail sticks to make small air vents. It will save you a lot of time finishing the cast. And i de-gas and flux the aluminum just before casting.

That would have prevented air - and CO2 - getting in and hardening the sodium silicate. That's why he mentioned porosity. But I wasn't aware that it would harden in air - I've used CO2 from a soda stream before
