Would love to see a video on designing a part like this and how to make a 3 part divisable mold. Love it.

[@wildin13]

It's always good for people to walk you through it visually, but if you can model the finished part the rest is relatively easy. Create a square or cylinder body that completely encased your part, create a hole for pouring. Use a boolean function (name may differ with software) to use the model as a tool to hollow out the mould to shape. All that's left then is to consider the split lines (how the mould comes apart and, more importantly, how it locates on reassembly) you can create surfaces along these split lines and use them to split the solid body. I know it sounds quite simple, but start simple and you may figure out on your own. Key things is to consider are draft angles, try to avoid pulling mould surfaces parallel to castings surfaces, and try to avoid fine detail. Small features are often hard to fill with casting material with the use of pressured filling methods or break off easy when splitting the mould.

Silicone spray works a charm for prevent concrete from sticking, just give it a once over before you pour you mixture and it will super easy to get you mold off.

[@Bender1729]

Thank you so much for the balloon trick! This is really cool! I already tried different molds and I always ended up having trouble removing the inner piece. And by "having trouble" I mean, I totally trashed the inner piece every single time to get it out even though I used oil / grease but it simply didn't help.

[@4570Govt]

Try coating the core and exterior pieces with a thin layer of vaseline(petroleum jelly) on the interior of all mold pieces as well

[@lostartifaxmaker]

I will try that with a resin printer so I can create a finer outside texture and extruded emblems (like Celtic symbols) on the surface. Great video. Balloon thingy was really cool.

[@mASLLSAm]

Great vid, you are one of the few who talk with the right speed, not too fast, not too slow. Keep up the good work!

[@vintageb3]

That would be "too"...not "to" surely?

[@ge2719]

a good brushing a petrolium jelly should help prevent the concrete sticking, and make it easier to demould.

[@ConstantijnC]

I tried exactly the same thing on my channel by making concrete candles. I also had exactly the same problem with removing the core of the mold. That balloon trick would have helped me so much. Youre a genius!

[@ggyun]

wow. I love the condom idea for the mold!! Good job!

[@J3rs3yM1k3]

This is really good stuff. You should have so many more subscribers.

[@PeterKNoone]

I made a bunch of these little planters with plaster and they came out great. Concrete still doesn't want to let go of the center plug. I've tried 3 times and even with a balloon it's a big nope. I think I'll try painting and sanding the center plug to a super glossy finish and then using a mold release product.

[@skakpedersen]

You are the coolest person on this planet! Thanks for sharing your work, not only here on KZbin, but on Thingyverse as well. I look forward to print and try out your design. Greetings from China

[@heavyweather]

You can also print a thin center piece from TPU, will come out without a problem with some wax or Vaseline on.

[@AlexandreEYLER]

I've already done similar 3d printed mold, destroying everytime the center part... Your balloon trick just killed me :D Thanks!

[@JoepSwagemakers]

You can use vaseline to make the center come of more easily and also to get rid of the small layer lines from printing

[@jasonthomashorn4794]

Balloon is an excellent idea! Going to use that.

[@steffenthorhauge9549]

Thank you for the balloon trick, I'm going to steal that for at concrete lamp I'm working on.

[@heavyweather]

The other way to get the core out is a multipart core that disassembles to the inside when you pull out the inner core.

[@Arterexius]

Use construction grade silicone on the inside of the mold pieces that make up the outside design (the pieces that are in 3 parts). That way you can smooth out the ridges and make it look even smoother

[@4tofromcafe]

I have downloaded the files. Thank you so much. I will let you know how it went when I have finished them

[@maverickstclare3756]

get on with it :)

[@jamesdonnelly8888]

I had to facepalm within 1 minute when it dawned on me what you were doing. Why didn't I think of this? Another great great video, thx

[@4tofromcafe]

Instead of the balloon you could coat it in liquid latex and /or use a flexible filament for your inner plug or maybe a disposable paper cup.

[@Amaro3210]

hi, is it possible to show us how to design these molds in software life 360 fusion ? that would be awesome :3

[@DD-bv9jl]

Step 1 sweep on path step 2 offset step 3 extend and then revolute it 360 degrees

Just give this man a like, he deserves it

[@trailblazingfive]

Wow what a great design; love the rotation symmetry usage in the design!

[@cisemyildirim6572]

you can try oiling the mold with olive oil or any vegetable oil. It may work.

[@Gig2Dave]

Thanks for taking time to do this video. Great idea.

[@peacewarrior9100]

Fantastic idea

[@facuricchi]

fantastic video! Tip for future projects: so that the cement does not stick to the mold you can use cooking oil that works perfectly! and if you add the ballon still better

[@teriyakipuppy]

Printed this today. It's awesome

[@pascalsalerno]

Another great vid! Thanks Alex. And kudos on the ingenious design and free share. The balloon trick is also great, as many others have commented. However, I just wanted to add a quick remark regarding your suggestion about using plaster: As far as I know plaster develops mold with humidity, as in the fungus. I would avoid it. But I could be wrong and maybe there are mold-resistant specialized plasters out there… Anyway, great vid, keep up the good work

[@nicolaasgrobler]

Thank you for the great video!

[@chemamokay3177]

You can try making a clearance guild line around the edge of it maybe that could help or as a slopr

[@chemamokay3177]

Another thing you could try is rubbing petroleum jelly on the print a light coat

[@Waltkat]

Great project! Amazing how creative you are with all your projects. How about coating the inside of the mold with something to act as a mold release? Silicone spray or even petroleum jelly. Of course if someone wants to paint the concrete or plaster after casting then you'd have to pick something that is easy to wash off. Silicone spray is not easy to wash off.

[@ChristopherBrandsdal]

Yes, yes and yes! Fantastic work! Great video.

[@Chackal1]

The best advice for me is to print the plug in TPU FLEX Instead of using the balloon, it works better. Greetings

[@soheilgharatappeh6061]

I love your works, man! Thanks for sharing them.

[@FlorinGN]

I just ordered balloons 😂😂 You nailed it! And the planters look amazing!

[@Bo-auto]

Thumbs up for the free download!

thanks for providing a file , i liked and subscribed immediately🤗

[@PeterKNoone]

Super awesome!!! Thanks so much for the 3d model. I'm going to print this up and cast a bunch of these for my wife's birthday....she will be so stoked.

[@PeterKNoone]

Do you drill holes in the bottom for drainage?

[@achappel]

Cool! I haven't done that so far no.

[@polyteky]

Hi, what print parameters did you use.

[@PeterKNoone]

@@polyteky I printed them using recommended settings for the PLA I used...nothing special. Printed easily.

[@polyteky]

@@PeterKNoone Thanks, what was the infill%

[@GuilhermeBrunowGomes]

Great mold! You should have an Etsy store and sell the printed out molds.

[@DennisJHarrisonJrHere]

Alex, holy crap man - your content is enthralling. It's obvious to tell how much effort goes into these. You've got what we call "the knack", for sure :) Bless!

[@UnearthedMind]

I came because I like your videos and was convinced that I would never want to make this...Now I want to make this :D

[@robrjohnson]

Try using cooking spray on the area where the concrete meets the mold. Concrete won't stick to it.

[@murrygans1786]

Very cool. Thanks for making the files free.

[@asztapaszta9]

Fantastic! Special thanks for the files, I def. gonna print it!

[@achappel]

asztapaszta9 awsome! Post a picture if you do :)

Cheers for this :) makes for a great activity for children

[@mzd8184]

Nice job, wonderful video!

[@capberganza]

thanks for the vid! awesome

[@christianp3388]

maybe some silicone spray on the inside of the three outer mold pieces to help the concrete release fully

[@waneck]

I really like your videos! Keep it up!

[@presse55]

Merci à toi - j'utilise tes précieuses idées sans faute!!

[@drakedelong3933]

I would have put a thin layer of epoxy on the inside to smooth it out and take away the layer lines

[@ChazBword]

Brilliant. I know I'm late to this party but this is an awesome idea.

[@CekkoLP]

You could try a thin layer of epoxy resin on the inner piece to make it really smooth 🤔... But anyway a rly nice video 👌

[@SzaboB33]

very clever!

[@jayzzone5862]

maybe a 3d printed clamp will lessen the use of electrical tape 😄 thanks for the nice video we can actually use it for business

[@futures.scalper.808]

I love combing technologes

[@mastercat]

awesome the trick of the core....

[@Taylor-bt5xs]

You should make these with drainage holes at the bottom

[@gabrieljanho9730]

Nice result!

[@dmilinare]

grease the center plug with motor oil or vegetable oil

[@kightremin]

this is a good guy

Hi, really amazing videos and channell, I follow you from Spain, and I like your content. Congrats.

[@kappersworld4103]

i dont have a 3d printer but i still give a like

[@lnxcodevideo]

The file on thingiverse has the (3parts) part, upside down, and there is a ridge that makes it very hard to print that way, before printing makes sure you reverse the part on the right side. Would love to have the original files, as I would like to add a "tool" to pull out the core.

[@DevilBlackDeath]

If that's a STL files that's easily importable in most 3D software ;) CAD might be another story, I don't have that much experience with it yet.

[@TheDaphnis]

Maybe applying petroleum jelly to the middle part could also prevent it from sticking.

[@ignaciobordafranz]

Muy interesante. Prontamente quiero realizar este tipo de moldee para Acer macetas de poliuretano reciclado!!

[@eduardosilvavargas8297]

Hi, thanks Alex for the video and files, does anyone knows the infill for the shells? when 3d printting? greetings from mexico

[@4104shobhit]

Hey how did you made 3d printed mould? Any video of making that 3d moulds?

[@chuysaucedo7119]

A balloon! Thanks for the video

[@thisisreallyme3130]

The de-mold damage seen at 4:51 (surface crumbling) isn't at all visible among the 6 planters shown at 5:02. Could you elaborate how many such castings you made before arriving at those 6 perfect planters? Or was that shot showing every one that you casted, but maybe the damaged surface was "away" from the camera? My question means to uncover how often you encountered de-molding damage. Great videos; just subscribed. Thanks!

[@geoper2]

great as always!

[@DanMoridin]

Did you try cooking vegetable oil on the piece that kept getting stuck? Just curious before I give it a go.

[@mcalin1859]

This is an awesome project, thanks for the files! Can you please provide the print setup (I think it needs supports but not sure about infill, layer height, etc.)?

[@achappel]

mcalin nope, no supports, print it as nice as you want, doesn't need to be super strong.

[@mcalin1859]

@UCe1Aj6VEO299Yq4WkXdoD3Q Thanks for the quick response!

[@pdj26]

If you add plaster to concrete it's sets really fast

[@knotrain2020]

Hi Alex... can I buy your molds to be sent it to me here in Thailand.. A great fan here!!!

[@mauriciosilvatube]

Great project! Will I have any issues if I scale this model to a smaller version?

[@jameswikan]

Hi Alexandre! Awesome video and file. Can I ask what infill density you used for the files? Cheers!!

[@django1364]

spray the moldings with an oil base liquid and the concrete won't stick to the molds easy to removed

[@louismaudet3119]

If you don't have balloon, you can use oil :)

[@mohamedmasoud4629]

Love it! just curious what software did you use to make the mold? im not sure of my process ( 3d design the item then reverse the model?)

[@wooffiedebeste]

Hi. Awesome videos! Can you tell me what the coloring powder is that you use in this and the lamp video? Or where you can get it. Thanks!

[@OptiqVision1]

Have you tried this type of mold with designs embossed and or extruded from the surface? I want to try that with some of my vector designs.

[@chrisellerbe3443]

what filament was used in making this? PLA, ABS, PETG?

[@glitzpresentes8331]

Genius

[@manavsingla8639]

Use powder on the surface for a better finish

[@linhagaucha]

hello guys, how could I have a more accurate measure of how much plaster to use in the mold to avoid waste ??

[@hussainali9999]

Nice

[@HighFlyD]

I'm curious how it's handling plant moisture in the longterm. Gypsum or plaster as you call it is water soluble. You can probably paint it with some primer, it should give it a little shine, but it must be plant friendly too.

[@schogaia]

Same

[@dimov235]

Very nice planters, but i wonder why they don't have a drainage holes?

[@speedyMaldo]

You can always drill holes for drainage. casting the model with drainage holes would probably present it's own set of problems. This seems easier.

[@slothandturtle8036]

Hei, I just subscribed 👍🏻 That will be one of my first projects when my printer is finally finished 😊

[@rompstar]

so regular PLA will work for this project ? thanks for sharing!!
