We do a lot of 3D printing at Tested, but it's a time-consuming process best used for prototyping, not mass production. To replicate our 3D prints, we invited Frank Ippolito up to Adam's shop to teach us how to make simple rubber molds and cast awesome resin copies. It's really not difficult to get started!

Painting Resin Model Kits with Frank Ippolito! ruclips.net/video/Xa3dqTViETM/видео.html
You can figure out how much resin you need by filling a measured cup with water, then put the 3D print in the water and the difference in displacement is about how much you'll need. Add a little extra for good measure cause sometimes the resin shrinks.
Or you could fill the mold with water, then pour that water into a measuring cup.
I was thinking the same thing
PongoXBongo not a goood way to do it
At first the density of Resin is often way different to water! Also you have to wait till the mind is fully dried, cause water reacts with Resin! Another thing is you method doesn't work on cutted mold and does not work on Multiform molds, cause the water would be anywhere but inside the mold!
One really good way to approximate the volume required is, pour dry rice into the cavity and then measure the volume of rice used. This is a rough approximation buy very close.
Tes_ Or make the mold and fill it with water and that is how much liquid will fill the mold.
I use Lego for walling up, it works well for small parts and is re usable.
The zigzag self-aligning technique is brilliant.
I love these videos with Frank. I'm really glad to see him as a more regular guest.
He had to be interesting to make it through a whole season of a tv show.
I've been doing some molding myself and have discovered that $25 of Oomoo doesn't go very far.
So, to reduce the amount I need to use on the non-rectangular models I'm making molds from, I've created a 3D printed outer wall to replace the foam core slabs on the side.
My trick to creating the wall without having to modeling anything is (using Simplify3D terminology):
- Load the model that you want to create a mold wall for
- Increase the model z-height (turn off uniform scaling, so you're only changing the height) by ~6mm
- Turn Top Solid Layers, Bottom Solid Layers, and Outline/Perimeter Shells all you zero
- Turn Infill Percentage to 0
- Turn on Skirt/Brim
- Set the Skirt Layers to a large number that is guaranteed to exceed the height of the extended model
- Set the Skirt Offset from Part to be something like 10mm (or however much silicon you want around the part in your mold)
- Set the Skirt Outlines to 2
Now when you print, you'll get no original model, but a double perimeter skirt the height of the model + 6mm. Simplify3D automatically stops the skirt once the extended model height is reached. I don't know if every slicer will do that, so do check the height of the print that gets created. If your printer is well calibrated, the double perimeter wall should be watertight.
I also increased the "Allow speed reductions down to" percentage to 40%, as I found this value is used by Simplify3D for the skirt speed and wanted the prints to complete faster. Other slicers may use a different parameter to control the skirt speed. The other way to fudge it would be to turn up the print speed to something much higher than normal, knowing that it'll get scaled down by some factor.
I suppose a vertical ooze shield would work just as well as a skirt (plus in S3D it has a direct speed multiplier control), but I used the skirt.
After my prints complete, I use hot glue to attach them to the base foamcore board, as per this tutorial.
I hope someone finds this useful.
Just wrap a strip of abs card around on itself and tape the ends then glue down. You can do this quicker than you can do the cad and you'll save money on printing.
I've just gotten done making some thick and wide rubber gaskets out of Silicone caulk :). MUCH cheaper stuff. To get it to cure throughout, add about 8-10 drops of glycerine, which is sold at cvs as skin moisturizer, per ounce of caulk. I don't yet know how well it will work for mold-making, but I intend to find out.
I MADE MY FIRST MOLD TODAY!!! I have so much to learn but i cant wait to make more
"For my head let's try and cast it in a flesh-tone."
"Ok."
Casts it in red.
+tyspyranger at least it wasn't yellow...
+Balancatraca I was hoping yellow
we're all hoping it my friend.....we're all hoping it...
Probably something Frank would have needed to know ahead of time instead of off-the-cuff lol

God damned I'm tired of people complaining about the premium member stuff in the comments. I'm not a member and I'm perfectly fine with them advertising it. These guys do a lot of hard work to bring us the content they do. I do believe tested is their full time job or close to it. Either way they are more than free to try to make a living off this. Premium membership or not I'm perfectly happy with the 100% free content that we get on RUclips and hardly bothered at all by the small bit of advertising they do. If I end up not liking their content or the advertising becomes cloying I'll vote by subscribing. Until then I for one wish to say how much I still appreciate the content you guys are producing. Keep up the good work. I'm sure I'll get flamed for posting this, but that's the net for you.
I meant to say unsubscribing, can't edit comments from iOS YT app.
Locut0s switch to Android
‘That’s the net for you’ god that profile picture is fitting
Norm, I like your interviewing skills. You ask all the questions that the viewers might think to ask. I'm sure you already know the answers, but it does take skill to pull out that information for the benefit of the audience. Keep up the great work.
Thank you! This is a proper way to advertise the premium stuff - telling us where to find more info while providing actual helpful content.
Time wrap!!!! Frank got his finger dyed in casting, but was already dyed in molding!!! Wouuuuuu!
lil tip tho
just in case u dont want to waste ur resin
just take a container fill it with water
mark the water volume, then put ur model inside the water and mark again
now u want to calculate the volume before and after the model dip in via marker that u made earlier
now u know how much resin u need to fill those volume (model volume)
keep in mind tho, some resin shink when cure.. so not a bad idea to put more resin
oooo. Don't tell Frank what to do. If you remember him from Face Off, He's know's everything. Just ask him.
I don't understand why so many people in the comments are hating on Norm? Like, he's there to ask questions, that's literally his job in this video! He represents the viewer who wants to learn how to cast stuff and he's doing his best to ask everything that might be obvious to the expert but not to the viewer!
This is extremely helpful and inspiring! I can't wait to start doing stuff :) Thank you guys for sharing, you're awesome!
Frank's voice is so calming. Like Dan Berry in the UK.
How easy is it, given a pattern for a 3D object, to 3D-print a mould for that object rather than print the object itself?
Illuminati And Triangle Worshipers Richard Bartle Seems like a sensible question to me?.. To be honest though, I don't know enough about printing and moulds. My guess would be that it's possible, although it would have to be a two part mould - I think you CAN print bendy rubber, but not as bendy as that silicone.
Illuminati And Triangle Worshipers
You don't necessarily have to print the whole outline of a box, just print the outer shell of the object with a little extra thickness around it.
Kjt
This absolute madlad poured the silicone directly out of the cup he mixed it in. I respect your audacity Frank.
Thank you so much for doing these videos, small words of wisdom and tips from people who have done this for years really help us at the beginning of the journey. I always take notes! A thousand thanks!
"Wear gloves, wear eye protection," says Frank, not doing either. :)
no protection required in Adam's cave
Lachlan Sumner 😉
probably not real ooo professionals damage themselves also from poor safety practices
Steve McQueen t-shirt, no further protection needed
Really mixing this poses no threat in fumes and it is the same stuff you dip you babies hands in to get a mold.... so really when it gets on your hands... let it set a little and it rolls right off LoL
I guess you could fill the mold with water, then pour it into a measuring cup, that way you will know how much resin do you need.
More likely, you measure the mold and use the measurements to figure out the volume. L * W * H = V
I was thinking the same ;)
VariablePenguin That gives you a handy maximum, but you'd still end up with excess because that's both the negative and the positive together.
Filling with water would be a pain because it would get the silicon wet, and you'd have to wait for it to dry properly... I bet you could get something dry to fill it (rice? Maybe too dusty) and use the same principle though
ANameThatIsn'tMyOwn I was thinking more that you'd make the mold. Then you know the amount you used to make that. Figure out the volume of the entire box and subtract the amount you used to make the mold and that's your amount to fill the cavity.
VariablePenguin Your right, I did not think of that. Good idea
I use Lego to build my molds. Quick and totally reusable
Don't you mean the "Container" for the mold material. I agree - fast to assemble and reusable. Should be able to calculate the amount of mold material needed quite quickly too.
But expensive.
Peter Moore Ingenious idea bro! Thank you four years later!
@@phillhuddleston9445 not at all, not at long terms
Do you prep the LEGO’s so resin won’t stick?
the Smooth On RUclips channel is pretty cool too...
but it's AWESOME to see things not going perfect too... how it works in real life!
AWESOME VIDEO!!! ty for it!
The more mass within the cup = quicker thermal reaction. Use a bowl to lessen mass and possibly lengthen pot life.
one of the best videos yet! I love the subject!
Knowing how much smooth-on products cost that amount of resin being wasted made me sad :D
always love Franks tutorials
frank aint wanna be there without Adam
0:10 glad to see adam's diagram of the solar system includes pluto!
But no Eris :-( lol
It doesn't meet all the criteria of the definition of a planet.
Deathbrewer yep just like Pluto
Why wouldn't it be there? No matter what you call Pluto, whether a planet, a dwarf planet, an asteroid or whatever, it doesn.t change anything about it. It just fits better a a dwarf planet category.
Deathbrewer
well thats your criteria. i take issue with the scientific community's definition of planet.
***** well its the only dwarf planet on the diagram out of the hundreds of others. the diagram is clearly depicting planets and the sun alone. i think its funny you get upset from me being happy something is on a map.
Excellent video here in 2019! Not the first time I’ve watched it. I retrospectively love the immediacy. Please make more videos with mistakes! It’s ever so lacking in this day and age. When everything is scripted to the umpteenth factor unscripted is refreshing.
More of these how to videos would be great to see!
The dude in glasses asks thorough questions. I am getting maximum value out of the interviewer. Good job man. :)
Water displacement to calculate volume first, figure out how much resin you'll need before hand!
I've seen people pour water into the mold to figure out how much you need, but I like this better, since it keeps the mold dry.
*****
But the cornstarch would embed into the cast and disrupt the surface. That's what mold release is for. They skipped that step, but I would imagine they sprayed it with some kind of release agent.
***** Or you could use birdshot to measure volume instead of rice and get a much more accurate measurement.
@@TimeConsumingInc sounds good or even maybe better rubber air soft bb's...
Gotta love Smooth-On
You both rule! Thanks for sharing. This is super cool 😎 💗🌿✨😆
Awesome video, so helpful! Thanks so much.
Would love to see more stuff like this!
25:47 I love the random boom mic creeping in. I know it happens, I just found it amusing the way it's creeping in real slow.
Norm is awesome. Haters gonna hate. Don't listen to them dude, thanks for helping to make this awesome content!
Very informative from both sides for newbie like me . Getting ready to try my own
Fantastic, are appreciate fine details and the work is first.! Thank you ...!
Frank was way more personable & likeable than when he was on Face Off. I almost didn't watch the video when I saw his face on it. Really good tips here.
Great video guys . Don't know why peeps are tripping about Norm . The other guy doesn't seem bothered if anything he's just so used to knowing the process that it's become second nature to him . So when he's asked questions it's almost refreshing
Not only that but Norm asking all these questions gives us new guys an insight on what it's like to be there learning from them in person . The questions help make the learning curve for some of us a lot easier as opposed to just having to watch the process without being allowed to ask any questions on the process
Ultimately everyone will have differences on what they like but I'm positive before the camera was rolling Norm made sure to let the guy know that he was going to ask the guy many beginner questions in order to set the tone and prevent the guy from being confused and annoyed from all the questions
The guy seems helpful and willing to share his knowledge so if he doesn't have a problem with it then those do that do have a problem are just wasting your energy .
Nevertheless let's keep it movin ☝️🐲
When you know how much resin you use to fill a mold, label the mold with that amount (in this case 4 oz). You will save a lot of resin over a small number of casts! Especially if you don't do a lot of casting for a period of time, it will save you doing the trial an error multiple times...
I used to keep an excel sheet with spot on amount of each component for every piece to be casted
I don't see why people have such an issue with them mentioning this was brought to us by premium members. If I give money to something, I like to see tangable results of that donation, and having specific videos that highlight the fact that they could not be made without that money makes the whole thing much more transparent and worthwhile.
tbh i dont care if it was brought to us by crazy bob down the street ... the fact that it is here and they spend a few moments of a video to say so and so paid for this ... is not a big deal at all ... it beats the heck out of 5 ads through the video
gawd, when I was doing resin casting I had that thing happen of the resin curing whilst I was pouring it because there was so much in the cup, it was the most frustrating thing ever. I learned from it at least
Great Video, starting to get into casting myself!!!
This is very useful, thank you both.
Excellent video! Thanks guys :-D
They should sell the recasts of the tested logos. I would buy that.
please make a video using hydrocast. Or something that can make a enlarged replica. BTW I appreciate the host asking a lot of questions, I think it helps newbies feel more confident. especially since these hobbies aint cheap!
nice video, i always wanted to know how this is done in detail.. and the resin looks tasty.. robocop 2 brought me here indirectly
Thanks guys!!!! Awesome Video.
best premium member episode so far
Thanks was looking for a good video of this for so long
This is great, do more!
I like Frank, because he is a nice enough guy to feed into the dumb stuff the hosts say. You can just tell he is a patient, good dude.
While to me, the fact he had to exercise patience with the questions asked (and obviously so) means that he believes he was only there to create resin copies of 3d printed objects and not to create an educational video on such. Therefore, to compensate for this, Norm had to ask more questions than he should have, which meant he had to show effort, which people perceive as a weak trait (for some reason).
Max Fark .......no. Frank would have done fine by himself.
And I'm not specifically talking about the silly questions...but just the awkward, not funny personality of Norm.
How fun! LOVE it :)Jen
Thank you guys i loves the video i can't wait to make my molds
One day, i´m gonna make resin copies of raisins.
Resin raisin - das amasin.
+1337fraggzb00N what's your resin raisin reason? And could have measured the volume of that mold with some other fluid first.
frumpyb the reason for a resin raisin is not reasonable.
'resin raisins' ...raising the bar ...and paving the way!! ; ) )
Firth Laist It´s raisin time!
+1337fraggzb00N Jaaaa! :D
thanks for sharing valuable info, it's fascinating !
This is one of the best Tested videos IMHO.
Cool video....this is why I watch Tested!
Boy I would sure love to hear what Frank has to say.
Nice video I am going to start casting some replacement parts for antique radios !
This feels like the old internet now because they sound too nice and reasonable with each other.
For anyone using a modern resin 3d printer -- Some printer resins stop platinum cure silicone from curing.
If this happens to you varnish your model or look for a non-platinum cure silicone.
Some really good, interesting information here. Thanks for showing those tip to us some of which probably took years to come up with. Great tutorial.
Thanks guys. :-)
That is one epic comb over Norm is rocking.
sweet . love tested.
So much interest in rubber. I need to learn this
this is the best kind of video.
Note this works well for models without gaps or small holes. Many models that people want are not designed for mass production and will need to be tweaked
I like the way the resin dried in the cup. I'd drill holes in it to hold pens.
This was one of the most informative videos I've watched the zig zag tip was golden
Stefan Mack It's physically impossible to cut a straight- to-zigzag line like he described. Notice they didn't give it a clear camera angle when he said "you can KIND OF see how its straight"??? Yeah... that's because it's not.
There's no clear camera angle, nor for Norm, because working hands and a cutting tool are in the way. Silicone CAN be stretched apart to be cut different ways. This really isn't complicated.
Awesome!
Also, with materials that have long working times you can use a vacuum chamber to extract the gasses and get a smoother mold. You should de-gas before and after pouring the silicone to remove as many bubbles as possible.
Depends on the application, but can be very useful. The materials (silicone and resin) they were using had quick working times for the sake of the video. Vacuum degassing usually requires a much longer working time than 2-1/2 minutes.
great! thanks for share
this will be amazing for dungeons and dragons and wargaming minis
You can use uncooked rice to measure the volume of the mold to get a rough estimate for your resin. Very cool video, I have molded a few things and learned a couple of cool tips.
Everything these guys do is ROCKET SCIENCE 😂🤣 😂 Awesome job on everything here
KNEW IT!! He was on face off!!
Thnx great tutorial and pleasant host
Frank was very aggravated at the redundancy of questions.
Why's everyone hating on Norm, he's doing his job
You gave me several ideas. I want to make a mold to make a cosmetic prostheses of my right foot toes that Iost severalyrs ago. Thanks
The King of Random video where Nate turns his foot into a Jolly Rancher may be of interest to you. They've also done prosthetic videos around Halloween time.
this is like watching some theatre ba recent grad's first day in a real prop shop. so many dumb questions, so much concern for safety lol
Cleveland in the house.
Frank already has some red dye on his finger when he builds the molds in the beginning, though he stained his finger while pouring in the end.
Imagine having this dude as your manager at work.
Re-recorded the foam-core molds. :D
Franks red finger, and messy mat.
A longer set time for the raisin if you use polyester achieves a stronger resing. If you drop a fast cured resin it can smash like glass, and a slow one is more elastic and strong.
Best vids ever :D !!!!!
I have so much respect for tested and Adam and all you professional guys. My only concern was the tested sign. If you get rubber underneath the cast is so hard to make flush. Not a problem here if course but if the piece needs to be level on all areas once cast, stick down on wood with carpet or double sided tape. Even if your master is stuck to the base, you can keep it and the mould will always puddle cast level
Adam reads XKCD!
Woot!
to see how much Mold material to make the molds, pour Rice into the Boxes then when at height you like above your project then pour the rice from it into measuring cup to see the Material needed, then mix up that much.
Norm this is great!! Thank you for sharing this with us. I have learned soo much thr the years!! 🙏🏼
Norm asked great questions for someone like me who's looking into starting out as a fresh newbie to sculpting and casting. Some I didn't even think of asking! Like cleaning the molds with rubbing alcohol. Frank was fantastic as a tutor for the questions. Loved it!
Very cool episode, if you want soft metal Econosil silicone jewellry mold rubber can take solder, lead free solder melted. Talc is good release, smooth on is great but costly for learning.
Thank you premium members! [Awaiting RUclips hate...]
Screw RUclips hate. I appreciate everybody that's bought products and subscriptions that helped other people get free or discounted content.
Pour rice into the mold then out the mold into a Measure up, look how much it needs add a little just for protection.
Water can be easier for many things, but that's a really great tip for something that water might damage. Quinoa and other fine grains (clean dry sand) would work as well.
