Casting Aluminum for the Home from a Simple 3D Print
Вставка
- Опубліковано 16 чер 2021
- Returning to the foundry, I cast an aluminum wall hook. The design of the hook had to take into consideration how it would be cast. Every face had to taper perfectly for the pattern to actually release from the mold!

Christ man, you really didn't have to make an entire demonstration for why single-pull casted parts need tapering and drafting but the fact that you did just shows how incredible you are as a person. Cheers to that
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
Can we just take a moment to apprecate the incredible finish he got on his 3d print? Damn man thats CLEAN
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.
Did I just sit through a 11 minute video without checking my phone or getting distracted? I was completely engrossed. It's a phenomenal feeling having stable attention. Thanks!
Thank you! I miss my own ‘long form’ attention span…. Old UA-cam 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.
Your voice is fantastic. It's almost from a 50's nature documentary. Lookup "Alone in the wilderness".
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
I’ve been designing Sand Cast tooling for engine/brake parts professionally for 3 years, and I have to say you are absolutely spot on with all of your information and explanations.
It’s really cool to see this done at home instead of with expensive mass production machines! Hahaha.
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.
I really don't think I'll ever get into metal casting, but if I ever do it is 100% because I stumbled upon this video. The whole process had me so drawn in and in awe. Keep this up!
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...
This guy is amazing. He managed to condensate TOO MUCH KNOWLEDGE in an 11 minutes video. The world need more people like you man! Thanks!!!
I can't imagine how many hours that you and other UA-camrs have saved the rest of us by sharing your knowledge of how to do things, and more importantly sometimes, how NOT to do things. . Also, your calm speaking voice lends itself to teaching. Great video.
Thank you! I have been a university teacher on and off for the last years…
Love the way you showed how easy or difficult it is to pull out the 3D model from the sand mold depending on it's shape. Please do more casting videos!
I keep telling myself that I can get away with ignoring draft. This demo convinced me otherwise!
its*
@@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
What a great tip about using CA glue and THEN polyurethane. Previously I had commented the plastic version would suffice for me, and this would make that especially true, but also provides a great surface for casting in metal, of course. Great methodology.
The black licorice really sold me with this video. I'm a big fan of black licorice and it's good to see another cultured soul.
Axis of Removal-that is easily my favorite death metal band!
Man, I hope you keep posting. You're the main reason I got into metal casting. I now make custom parts for the guitars I build thanks to you. Your videos are always a great inspiration.
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?
A Brian Oltrogge video in notifications is always welcome, but a Brian Oltrogge video with Aluminium casting, and a Drunk Octopus meme, really makes my day. Today is a good day 👍
Today is a good day to fight!
There are a lot of metal casting videos as of late on UA-cam. This video is among the best based on a large sampling.
Many people wish to make videos and appear as knowledgeable and they often give inferior and flawed instructions that will result in a lot of wasted effort and potential for long term flawed and erroneous methodology.
This is a great video for 'small scale lost plastic 3D printed model metal casting' and offers good instructions and sound methodology.
Oh my goood it's been forever since I saw that "drunk octopus wants to fight" image! I remember taking a picture of one I found in a restaurant more than 10 year ago
This is one of those channels that uploads rarely, but every time you do I go and watch a bunch of other stuff of yours. Looks awesome so far!
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 )

@@ahmdabdallah5811 cool story bro. Needs more dragons.

I adore this format, the music, the voice, the jokes, the editing, everything.
It feels so nostalgic, I remember watching those old tv documentary's on random stuff and falling asleep to the calming voice every single time.
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.
Love that subtle Fifth Element reference with the match.
I am a meat popsicle…
All of the greatest designs are borrowed from nature. Love this.
YESHUA GOD ALMIGHTY is perfect in engineering isn't HE?
What a great surprise this morning!
Indeed!
that's what the ATF said
I always thought of draft angles in relation to the normal of the parting plane. This just bent my mind and opened up a new world.
That was the seed that sprouted this video!
Forgive me if someone else has already commented this, but depending on the material you 3D print with you can use acetone to smooth the surface instead of doing all that sanding. For parts such as this where it's mainly aesthetic and there's no real tolerances required, it would be ideal and save you a fair bit of time. Nice work!
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
This is a great reference for 3d print-to-cast projects. Thanks a bunch for showing us this, and well done with that wall hook!
Welcome back Master !
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 UA-cam… pay him more so he can quit the day job and focus on producing more content‼️ 😊
This
Amazing job. This is one of the cleanest sand castings I've seen.
Reminds me of some old how to video from decades ago, the music, the way he narrates and even how his narration sounds all make me feel like this is from an early 90s pbs show
Thank you!
11 Minute video, the complete process clearly demonstrated, including an explanation on the importance of draft. No wasted time. Outstanding!
Thanks. I try to keep things moving especially now when you have to compete with 10 second videos on Reels and Tik-Toc…
Quality ! Thorough explanation while kept simple and relaxing. And a good hand sanding instead of using a machine, because sanding is an addictive activity for anyone who started. Love it !
Your videos always remind me that I want to build a foundry, but never do it!
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 UA-camr 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
Wow, this is like watching a 60:th instruction video.
The voice and text is perfect. And a interesting video.
Thanks! Glad you enjoyed it!
Thanks, Brian for the easy-to-follow process. I'm now tempted to give casting a go.
I see a new video from Brian, I drop everything I'm doing to watch
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.
The fact you can explain the process in a concise easy to follow manner without all the fluff is really helpful and shows you know your stuff. Awsome video!
I miss the Old UA-cam too! Thanks
Oh my goodness so much work for a wall hook. As long as I live I would never spend that much time doing anything that took that long. Wow. Incredible what people are doing these days with their time. I thought spending 2 years to restore a car was a bit crazy! But worth 6 figures when done verses a $10 dollar wall hook. That takes days. Still an absolutely incredible process.
I get it… but imagine you are restoring a 1920’s motorcycle and you need a custom pedal. This is how you could go about casting it yourself! Time becomes less of a factor.
When I was a young man, I worked in a large foundry where they made large valves of cast steel. A hot, dirty and sometimes dangerous environment. A couple guys were missing fingers or more from accidents. They used some type of sand and resin mixture and pressed the sand in with air tools. The pattern makers were true artist and craftsmen.
I used to have a small sand pre-casting. It look like a piece of art work and lasted a long time on the shelf before getting smashed. Cheers, Scott
I love the 1960's / 1970's sound of the voice over, nobody does that!
Loving the hungry snail. Great job as always Brian. Keep it up. You inspire me every time.
Ok, NOW I want to get into 3d printing. Not before watching this video, but after watching this video. 🤩
I enjoy that the narration style reminds me of a 1960s instructional film. In a good way.
Ha! Thanks…
I’ve been waiting for an upload which feels like years, don’t make that feel like a burden though every time you upload I am still so impressed. I’ve always loved the home made furnace, I’ve wanted one for years.

There is something about your voice and speak that reminds me of infomercials from the '60s. It brings authority, so it is quite nice. Great video, by the way!
Thank you! Only explanation I have is “midwestern dialect”.
I think the Midwest had more to do with US culture in the 50-60’s so more of the information and media came from here.
The clinical perfection with which you conduct your projects is admirable
I don't know how I ended up here, but thank you for this. In the 11 minutes of video, I was inspired by your setup, instructed by your narration, and awed by the results. Well done on easily some of the best casting work I've ever seen. Top quality content and work sir!
Also, that hook is great.
Niceee, I love that you showed everything in such a clear manner! :D That demonstration of the different cuts really made it easy for me to understand why your particular shape worked
Good to see you appreciate the best licorice you can get 👍🇦🇺
This is correct.
This video reminded me of the show "How it's made" on the discovery channel. Great job!
Thanks!
thanks for demonstration with undercuts. I have a project that I'm working on and I will have to revisit because of this tip.
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..
This video is so amazing. As a materials engineer, I had enjoyed every second of it.
I am glad you liked it! You might find my monkey casting video a good time, too :)
Was feeling pretty crumby today. This video brought me some joy thanks
Hey, I am glad you liked it!
Thanks for pointing me to The Westerlies. 🎼
The voiceover sounds like old documentaries, i love it!
Awesome video! Definitely going to be using tips from this when I think of something to try as a first cast from a 3D print - thanks!
The intro was a real throwback to late 60s manufacturing videos lol.
Great narrator voice, reminds me of those old instructional film reels from the 50s or 60s.
I've never seen the super glue and polyurethane trick used on 3D prints. It looks amazing, thank you for the tip.
It's like christmas x10 everytime you upload ❤
this brings back memories of metal work at school, only back then we did not 3d print our casting template
Yup, good times…
This has literally made my week seeing this!
Welcome back Brian you have been greatly missed!
Very nice! Did not think about the CA glue and Poly urethane trick, I'll have to test that out as your part almost looked vacuum molded. Thanks!
Thanks! Learned that from a pen turner…. I was amazed at how nice the finish ended up!
I normally can’t endure more than a minute of most how-to-clips but, this one was enjoyable, highly informative and covered all the bases. Thanks for posting!
You bet! Hope you come back and check out some of my other videos!
This is the most satisfying and impressive thing I've seen this year so far.
Ha! Thanks!
So glad you're back Brian.
"You see that coat hanger there, I made that." People are going to look at you like you are crazy lol.
Fantastic to see you back! I was wondering where you had got to. Great casting result!
I love that your forge is made out of a keg. Definitely need to turn one into a forge.
Nice to see a clean and tidy working practice. A good example of how things should be done 👌
Every time you release a new video I have an urge to binge watch your entire library again! You are in another level Brian, Congratulations!
Also, you should do voice acting, you have an excellent narrator voice!

I like the trick you did with the audio it reminds me of those old videos we watched in school.
2:06 Wow, I wasn't aware that Darrell Lea was available outside Australia! It's always seriously tasty (Dark Choc. Licorice Bullets are my fav!)
*Opens Amazon browser window*
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.
That is the most beautiful hungry snail I've ever seen.
Sometimes you have to question yourself when you look at something and think “man, that looks like fun to file”😂
I'm so happy you made another video. You are so talented and I greatly appreciate that you share your talents! 👍❤👍
I've missed the hell out of your videos, man...
I'm sure you're not the first, but using a stainless steel beer keg for the outside of your furnace was a GREAT idea :-D
it's refreshing to see a video made with so much care. Articulating every step along the way, such a rare thing on youtube.
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 UA-cam rewards more superficial content. Stay strong and resist and I will too!
I can’t thank you enough for this video. I’ve been having no luck with green sand and the techniques you have share will lead me to success!
I can never look at those coat hooks in the same way again.
this is content making at the finest. everything is well planed and executed. thank you for sharing your skills
studio.ua-cam.com/users/videoRMQfzPoPbx4/edit
Very patient fellow, that's a great result to a process I haven't seen used in workshops since I was a boy, brought back some fond memories of my dad, nice work
Awesome voice over. Really old school sounding.
damn so much work for a coat hanger.
Yeah lol but good for learning
Fantastic! I started building a forge after your video of it and never got around to finishing it. You may have inspired me finish now. ..."Hungry snail wants a cracker." Not gonna lie, a little bit of coffee came out my nose. Lol
This is always how I planned on doing casting, thank you for demonstrating!
My grandfather was a pattern maker when I was a kid in the early sixties and I remember him explaining the craft of building a wooden pattern so that when as the positive pattern it was packed around with casting sand it had to be able to be removed without disturbing the sand. I was fascinated then and still am 😁
This is how you do a maker video, you explain why and not just how. Thank you, Brian!
I miss the old, long form UA-cam videos where most people spent more than a couple days on a project…
Here is a tip for you, instead of using super glue to generate a smooth surface on the 3D printed part, use UV light curing resin instead. It makes for a super smooth finish that only needs light sanding and produces an extremely nice finish that wont transfer artifacts.
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
Brilliant - great demo, thanks.
One of the best way to waste time/effort/material and energy, WELL DONE SIR.
I think I would have just used the printed part. But to each his own. Good video in any case.
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
"The hungry snail"? no "Slurms McKinsey"? Yes
I thought "Designer Women's Shoe Heel"
it's like a voice from the 60's.. 🙂 Great work!
i've worked in a bronze sculptor's foundry, on wax models through to the finished life sized pieces, a small crew pouring glass into moulds and have done some lost wax and cuttlefish casting for small metal objects.
awhile back, i was noodling around with 3d applications/models and renderings...now, i am about 10 months in with 3d printing...it's very VERY satisfying to finally hold in my hand that which was only viewable...on a computer screen.
thanks for your processes!
You bet! Have a great weekend…
Beautiful work! But man, it only has to hold up coats, so the 3d print is plenty strong enough, and looks great after the CA and polyurethane. I would have just gone with that and saved time :P
I might post the 3D model on the website with a modified back for just that reason…
Made an awful lot of work for yourself by not ramming that sand.
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
Love your style Brian :)
so glad to see your excellent work back on youtube.
