Been 3D printing since 1998. I love it. Back in those days the machines were very expensive so you sent the files out to be printed.

[@dyscea]

It was a thing? I thought it was impressive that this “new tech” was so affordable to the casual, home artist.

[@RobertTolone]

@@dyscea Home printing is relatively new. In the late 90’s there were service bureaus that would print your files. But they were very expensive prints. I first used them for making toy prototypes for Star Wars kid’s meal toys. The characters we hand sculpted but the machines, robots, speeders etc. we modeled in CAD and printed on 3D machines. I’m a character sculptor, mold making is integral to my business but not the main focus of my studio.

@@RobertTolone Very Cool, I did my Uni Thesis on the LOM RP system back in 1995, the Hypothesis , (just a Uni thing, doesnt matter if it fails or not, its the idea that counts) was using hemp paper to make stronger models, i made a system that could layer the material, the hemp paper, like a laminate...so my claim to fame, if the F1 cars use, carbon fibre 3d prints, i was the first !!! ...how do you like the Fordom wax pen?, does it last a while, good value?

I believe 3d and 4d printing will be among the most important inventions in human history. Especially now that scientists can print food. Imagine a ship lands on Mars. It sends out a rover which builds a structure, like a robot garage. It then mines its building materials from the planet. Now it can build a base. However, it could use some assistamce. It prints another rover, who prints another rover. They build bases for the human to reside in. and so on...

It’s interesting that I was in my shop this morning having trouble with a lighter because of the cold. I started designing a “hotbox” in my head to keep things warm that need to be kept warm, then I came back to the house for breakfast. I’m watching your video and you put your mold in your fridge which you called a hotbox and instantly I realized I overcomplicate things lol. I have a bunch of gutter heaters in my work truck that we use to keep enclosures from freezing in the winter, it has an automatic thermostat set at about 50 I think. Otherwise an old fridge would be a perfect solution and save me many hours and dollars. Thank you sir

[@Larry]

Could you use zip ties or velcro straps rather than rubber bands to hold the mould? would they be more accurate for pressure?

[@Gundalow]

Hello you! Fancy meeting you here! The only reason as to why I personally wouldn't use those two would be having to cut the velcro to size, making it useless for larger molds, and zip ties are 1 time use, as opposed to rubber bands being a little more reusable and versatile, but other than that I see no reason as to why they wouldn't work.

[@StudioRevoct]

Larry I swear I randomly run into you somewhere online everyday, you're becoming a comment section staple. Anyway you could use a perfectly sized hard container if you really wanted it perfectly pressurised. I noticed when using zip ties it's easy to either under or over tighten the mold compared to rubber bands, but everyone has different methods. Try and see what works for you!

[@Ghryst]

you really need a solid mold clamp, preferably the one that the mold was created in... but this amateur destroyed it. recommend you stay away from this bad advice. 2 part molds produce far superior casts, which is why the extra step was invented in the first place. it wasnt just done to make the job harder

[@StudioRevoct]

@@Ghryst there are benefits to both one and two part molds, it's unfair to say one is better for everything compared to the other. Also this guy's definitely not an amateur.

[@Ghryst]

@@StudioRevoct there are no benefits to hacking up a perfectly good mold in such an unprofessional manner, hence then "amateur". protip: "old" and /or "experienced" does not equate to "not amateur" Amateur: noun: 2. a person who is incompetent or inept at a particular activity. adj, 2. done in an incompetent or inept way.

Very interesting! I’m surprised how simply the silicone mold is cut in half. I always figured it would be much more complicated and would need to somehow catch the exact outer most edges. I guess that’s a big advantage of using a mold that is bendable and can stretch some.

Hi Robert, what is the last chamber ? pressure or vacuum ? thank you. very informative

[@airriflemaniac]

Has to be pressure based on the way the lid is.

[@cyrushomazaad3781]

❤️brilliant, thank you very much for sharing with us 🙏

[@Freigeist20789]

Would it be useful, after filling the mold form to once again do the vaccuum chamber. To remove any introduced air by the dripping?

[@mrc8308]

Yes this is what I do. Actually I skip the inital degass and just degass the rubber in the mould. You do have to make the mould box/tube much taller though, as the rubber rises in the vaccum chamber. If Robert had degassed this mould quite some rubber would have been lost over the sides.

[@keeleycarrigan]

Interesting. Almost all the mold tutorials I see are for two part molds. Great video and explanation

[@michaelholmes2101]

Hello again Robert, when you put he resin filled mould in the tank, was that another de gassing tank ?

[@darksunrise957]

Considering the lid is positioned to push out from the inside, it's a pressure vessel, which is generally used to reduce bubbles in casting because it crushes the air bubbles so small so that you can't even see them any more. Or so I remember hearing.

[@sowellfan]

Thanks, I was wondering the same thing. Weird how vacuum and pressure are both used to reduce bubbles, but in different contexts.

Great video, thank you. The way you used a jagged cut to split the mould was inspired. and makes perfect sense.

[@moodberry]

Loved seeing you do this, but one question: What is the "tank" for that you put it into after pouring the resin?

[@mattstokes9624]

It is a pressure tank. Any remaining air bubbles are compressed so that they are eliminated. If you did it in the vacuum chamber it could bubble over.

[@LaZieGoblin]

@@mattstokes9624 Doesn't that cause issues later? Since they could still be trapped inside the model.

[@RobertTolone]

Once the resins is cured it locks the bubble in the resin and they don’t cause problems.

[@MrStickykey]

@@RobertTolone what psi is needed to eliminate the bubbles?

[@RobertTolone]

@@MrStickykey I run my tanks at around 50 psi but I have never really tested what the minimum psi requirement is.

[@RobertTolone]

That “contraption” measures accurately to 1/10 of a gram. You can literally add a drop of resin to a container and watch the scale rise. Balance beam scales have been in use for thousands of years and some designs are capable of fantastic accuracy while weighing tiny objects. I love my scale. Plus, no need for electricity or batteries.

Years ago i used your method to make deep sea fishing lures in hawaii, thanks for the memories, good job

[@RobertTolone]

Did you attach the hardware (eyelets, weight, etc) to the lure after the castings cured or did you pour the resin around them? Also, did you add microballoons or some other material to make the resin more buoyant?

[@borisbarat4858]

Very nice video. What I found working for me as frame to keep the silicone mold in place is LEGO. I build a frame from LEGO, pour the silicone mold into it. Its easy to take apart when creating the mold and simple to re-build when you want to use the mold for resin pouring. I gives the cut mold form a lot of stability when pouring the resin in. For larger object the rubber bands will not hold the mold perfectly. The only negative is, if you are not careful and spill the resin on the lego, there is no way to properly clean it and ....

[@ArcticFlies56]

Bob, it’s a strange thing how we get use to doing things one way and even though we hear you telling us that pouring the hardener in first then pour in the silicone because it mixes better that way. Well, today I decided to give it a try. Low and behold you were right as always. Very few streaks and silicone didn’t stick to the walls of the cup!

You Just Put A Wrinkle In My Brain! I always thought you needed to place a fantastically precise barrier in the space between his arms and body,,,,and legs and base,,, but you just separate and cut the mold rubber that fills those areas as you demold the model. I'll remember this next time I ever make one of these types of molds.,,,,,,, Thank you for sharing this,,, and that's all I have to say about that........

[@RobertTolone]

The trickiest part to cutting those rubber islands in the model is knowing precisely where they are. If you stretch the rubber too far the cut will be off-center and that can cause problems when you close the mold to pour the next casting. If you cut it correctly it works perfectly!

One thing I learned from another KZbinr- if you can get your hands on some lego blocks, you can use them to build your mould case. You can make them the exact size you need, the disassembly is easy, and instead of using rubber bands which might squash the mould, you can just build the lego case around it again when you do your casting.

Yes, many like people using legos. I don’t have any so I don’t use them for making molds. It would be fun to try it out.
