We are joined by Game Artist and 3D Printing enthusiast Jonathan Shaller who is kind enough to share with us his tips for recycling all of those worn out silicon molds.
Also, guys, keep in mind that this will be messy, flakes of silicone everywhere Take all measures so that they are contained and will not reach the water supply
Great idea it seems for silicone mold making as from what I've gathered the silicone molds needed don't need to be super rugged and heavy duty. Because the problem with mixing old silicone with new silicone is silicon doesn't even stick to silicone, at least not with the same bond strength compared to using new silicone on a clean prepped fresh surface of anything other than silicone. So for applications that are short term use and dont need the strength of original fresh silicone this is great!!
Ty so much for the video... I wanted to ask though you have where you can see the granules that you put in on the top it doesn't show on your pieces? Your piece is still smooth and not bumpy? Thank you again for the video
Hello! Great video! I am always sceptical when creating a silicon mold, as it's quite expensive and - until now - not reusable. What proportion of catalyst do you use when mixing a 50grams new/50 grams old ratio, the same amount you would for 50gramms of new silicon ? In adavance, thank you, and have a great day!
thank you , I work quite a lot with silicone and resin/bronze, recycling , well done. now at the moment I just mixed 1 and half kgs of pure silicone, 10% cat was recommended. but the cabiat . the barrel of silicone is over year old?? . the mix kicked in vacuum chamber. like thixo concistency. I wonder should I try 5% tomorrow
@@jordansams6240 I've used recycled silicon with pressure pot and the chunks were poking the sculpture and overall making a worst silicon mold. Wouldn't have happened if I had done a detail coat first, let it set, then put chunks and pressurise.
That has really helped a lot, thank you! I bought a 3d printer and I'm currently making a valve but need silicon parts to seal it off. Do you think I would get good results making a 3d printed mould and inject the silicon into it to produce my parts? It has to be food grade, so I also need to make sure any ground down silicon is of the same variety. You could make endless products by what you've shown us in the video. Clever stuff! Especially sharing your expertise for free.
yes I was wondering what the red catalyst is too...it would be great to know for future moulds I only use a couple of times and for spills, flashing and, the inevitable (with me anyway) complete disasters lol!
I do have a question though if you have a 3D printer and you've already made the item or and have the capability of making the item why would you make a silicone mold to make the same exact? Seems like a load of extra work vs pressing "print" on the printer already owned and the labor having already been done.
FilmFactry I don't think that would be a problem... at the end the new silicone is going to bind and fill the gaps... try on a small piece to see if it works... because if it does...
Do you still use the same silicone to catalyst ratio as you would if you were not using the recycled silicone (aka for 1:1, would it still be 1:1 of catalyst to new silicone with the extra bits as just an addition to the overall mix?)
J Com I imagine you would need to make shore they are compatible, a little test on the side first helps... but that's just the question I was asking my self... you would also need to de grease the silicon with cleaning alcohol...
Not satisfied with this method. Not only will it create lots of fine bits of silicone that will be hard to keep track of, but it's not well suited for storage since it will be very hard to clean silicone pieces that small should they, say, get so much as dusty. You also are very likely to get bubbles trapped among all those fine particles.
So none of those chunks interfere with fine details or clog channels? Say for instance damming an arm so that silicon cannot flow all the way to the fingers.
Jerry, for YOUR application, consider saving some of the liquid-only silicone mix to hit the finder points first, then pour in the recycled chunk mix afterwards. you get better assurance of the fingers and chunks take care of the rest?
@@kennethyoung1980 I have tried both and neither were effective, and would bind that could burn out the motor. I tried the blender and food processor with water mixed to help but it was not effective.
Thank you for this! I goofed on a mold and was hoping there would be a way to save the silicone I used
great! it should also work for the little ammount of silicon that stays in the mixing cup. thank you for the tip :D

clever and responsible, I like it!
Seems like a pretty great idea for when you’re making a bunch of one time use molds. Also saves cost, silicon isn’t cheap.
Great video! Quite a savings if you're a maker. Many thanks!
this is awesome i luv that idea , but i would use an electric grinder instead for saving time
and for saving flesh 1:17
Brilliant!

Very helpful!! Thank you.
Outstanding 👏👏👏
Great video! Do you believe that the recycled silicone makes for a more durable mold?
Oh my god, thank you! I never thought to do this, and silicone is so expensive here in Aus!
Hi, we are silicone rubber factory in China, how many silicone rubber you buy every month?

Thank you 👍
Nice! The ratio of catalizer is calculated based on the amount of new silicon (disregarding the amount of recycled one), right?
Nice. Amazing idea.
Put a motor on that meat mincer and that's that
That finger had me crying 😂
Just need to add a tall funnel and an electric motor. Thanks for sharing this!
Thats good to know as I wondered about reusing it. What is the red catalyst btw?
Really helpful thank you!
Very useful tip for a beginner like myself ☺ 👍
Brilliant, many thanks : )
great video !!! Keep it up!! just a question , what should we do with expired silicone sealant ?
wouldnt that add some small ridges or texture in the surface (because of the granulated silicon)??
+huevonIII If you don't use a pressure pot for molding you should be fine, the bits of silicones gently float in the fresh one :)
amazing tip, thank you Vincent and Mold3D
no
@@hylgariss what if you do use a pressure pot but you also pressurize the silicone as it's setting?
@@jordansams6240 I've used recycled silicon with pressure pot and the chunks were poking the sculpture and overall making a worst silicon mold. Wouldn't have happened if I had done a detail coat first, let it set, then put chunks and pressurise.
Omg I been working on molds for my hookah tip business & it’s been a disaster. I’m praying that this method would redeem my $200 spend on silicone
I wonder if the different shore strengths would make a difference ? Mixing a 00-20 with a 15?
@Mold3d did you try to heat or freeze the silicone first ? been having a hard time recycling it
what is that solution you used again? aside the catalyst. or is that a silicon mixture and you just add the grinded rubber?
Pretty much
That has really helped a lot, thank you! I bought a 3d printer and I'm currently making a valve but need silicon parts to seal it off.

Will making a mold this way work with clear resin? I’m amazed the mold is still smooth with the ground silicone.
Great thanks
Can you give the name of catalyst you used for mixing original silicone and recycled one..??
yes I was wondering what the red catalyst is too...it would be great to know for future moulds I only use a couple of times and for spills, flashing and, the inevitable (with me anyway) complete disasters lol!

3D printer takes more time and at a time you can print only one. But in multiple mold you can create many at a time. Also price will be cheaper.
yay thank god lol I knew there was a reason I kept all my little bits of silicone or my disaster molds lol
Good job
Can I use a Magic Bullet or an electric blender to shred the silicon?
Thanks you verry muchhhhhhhh
Ever get issues with trapped bubbles?
Also do u think you get a whole cup more like if u were using 1 1/2 white and 1 1/2 red?
Can you melt silicone raw without any chemicals or additives
Hey, buddy, is there silicon in the kids 'toys?
Can you use a food chopper or processor?
I tried that along with a coffee grinder and both did not work well for me.
It is not possible to heat and melt silicone?
Newly into making molds. Would like to know what you use as a catalyst. Love the video
That should come with the silicon you're using and it must say the % needed
when will we know the catalyst and the % of the fresh silicone?
Awesome!! Thx👍
can be silicone disolved ?
I do use pressure for molding and casting, so this may not be a good solution?
FilmFactry I don't think that would be a problem... at the end the new silicone is going to bind and fill the gaps... try on a small piece to see if it works... because if it does...
Hmm, wonder if you could attach an electric drill to the handle side...
Can you also use scrap silicone putty molds in with liquid silicone?
Can you use this technique if youre pouring a block mold (aka one side at a time) ?
Do you still use the same silicone to catalyst ratio as you would if you were not using the recycled silicone (aka for 1:1, would it still be 1:1 of catalyst to new silicone with the extra bits as just an addition to the overall mix?)
The catalyst is just for the new silicone; the recycled silicone is already set
Way cool. I imagine it's not ideal to mix platinum and tin-cure silicones, right?
J Com I imagine you would need to make shore they are compatible, a little test on the side first helps... but that's just the question I was asking my self... you would also need to de grease the silicon with cleaning alcohol...
Gonna try it with Mold Star 16 soon. Good chance it will work. Going to look for something that grinds finer.
Why not a food processor??
Hi i just wanted to ask that can we use a silicone mould for casting multiple times?
Yes, its a mold, its what its for.
Not satisfied with this method. Not only will it create lots of fine bits of silicone that will be hard to keep track of, but it's not well suited for storage since it will be very hard to clean silicone pieces that small should they, say, get so much as dusty.

hi what shore is the silicone you use ?

Jerry, for YOUR application, consider saving some of the liquid-only silicone mix to hit the finder points first, then pour in the recycled chunk mix afterwards. you get better assurance of the fingers and chunks take care of the rest?
But not bumpy?
I thought this was going to be about melting
I thought I could just melt it down
hi, what is red catalyst
I would say a fancy name for the reactor of silicone. The enabler, the one that turns silicone hard. All my guesses.
food processor $40 US
It like Jesus come back 😂🤣
Could you use a blender etc?
Kenneth Young Or maybe a coffee grinder or magic bullet?
@@naomianomaly8540 exactly you get what I mean!
@@kennethyoung1980 I have tried both and neither were effective, and would bind that could burn out the motor. I tried the blender and food processor with water mixed to help but it was not effective.
💪
thats siliCONE not siliCON
We need scrap silicone rubber，if you have please add me
I have silicon scrap
what's the red catalyst?
Shekaran Jag if you take the red catalyst you see how far down the rabbit hole goes.
Looks like chunky barf
I did a video 13 years ago showing how to recycle old silicone molds, works better if you use a pressure pot
