BBDINO Super Elastic Silicone Mold Making Kit 70.56 Oz, Liquid Silicone for Mold Making, Silicone Rubber Mold Making Kit 1:1 by Volume Ideal for Casting 3D Resins Molds| Silicone Molds Jade Green

I recently discovered the wonders of BBDINO Super Elastic Silicone for my intricate sculpture projects, and I couldn't be happier with the results. This platinum cure silicone offers a host of features that make it a must-have for any sculptor.The standout feature of BBDINO Super Elastic Silicone is its incredibly low Shore hardness of less than 10A. This characteristic ensures easy demolding of even the most complex sculptures without sacrificing fine details. With approximately 250% elongation, the silicone's exceptional elasticity is vital for preserving the integrity of my sculptures during demolding and handling.One of the things I love about this silicone is its versatility in mixing options. Whether you prefer volume or weight measurements, BBDINO Super Elastic Silicone accommodates both, allowing for accurate and consistent mixing every time.The silicone is perfect for various mold types, including one-piece molds, glove molds, and matrix molds. It captures intricate details with precision, ensuring faithful reproduction of my sculptures in the final cast.However, it's important to note that BBDINO Super Elastic Silicone requires specific curing conditions. It must be cured above a certain temperature to ensure timely curing within the recommended 3-5 hour timeframe. Failure to meet the temperature requirement may result in longer curing times or incomplete curing. Additionally, users should be aware of the material compatibility of their master object to prevent cure inhibition, as this silicone is sensitive to various substances.In conclusion, BBDINO Super Elastic Silicone is an exceptional choice for sculptors seeking a high-performance molding material. Its low Shore hardness, outstanding elasticity, and compatibility with different mold types make it an invaluable tool for capturing intricate details. Just remember to follow the curing instructions and ensure material compatibility. With BBDINO Super Elastic Silicone, you can bring your artistic vision to life with remarkable precision and ease.Edit: 6/25/23 - I wanted to address some reviews I recently read about:-This silicone is very thin and runny which is exactly what you want to flow into the details of your object.-Also this is not a brush on silicone and should be not used for such applications.-Using this in the summer/ higher temps (80F+) will cause this silicone to cure faster than the stated timeEDIT: 1/8/24 update - Still my favorite silicone to date. Extremely cost effective and has great shore hardness & elongation. I saw a 1 star video review stating that the silicone does not cure but the user was using 3d printed RESIN which contains SULFUR and WILL CAUSE CURE INHIBITION to platinum cure silicone. DO NOT DO THIS. Platinum cure silicone will not cure when in contact Sulphur.Also this is not a paid review, I make and cast sculptures full time for a living and this has been the most hassle-free and reliable silicone I've ever used.

I do a lot of 3D printing, but I needed to make a part that was both flexible and durable that I couldn't 3D print. Partly because of the shape, and partly because my printer can't handle super-flexible filament.I saw this stuff on Amazon and it seemed like it might work, so I ordered the small kit. I then 3D printed a mold in PLA, then coated the parts that needed to be smooth in XTC-3D epoxy. For the parts where surface didn't matter, I just left the raw PLA, layer lines and all. Because of the odd shape, I had to make a 4-part mold that could be screwed together.Once the epoxy was dry, I mixed up a batch of this BBDINO silicone, being careful to be as precise as possible with measuring. After mixing thoroughly, I took a 60ml syringe and sucked up all the silicone mix and then squirted it through the access hole in the top of my mold until it started coming out of the vent holes.At first it went pretty well, but after a couple minutes the silicone started seeping through the joints of the mold. I figured that might happen since this stuff is pretty thin - which is a good thing for getting it to flow into all nooks and crannies of the mold, but I should have done a better job sealing it. I made a frantic effort to tape up the seams to try and stop the leaks. Fortunately, it worked for the most part. But because a little bit leaked out, I didn't have quite enough to fill to the top anymore, so I quickly mixed up a second small batch and injected that as well. No big deal. I left the syringe sitting in the filler with a little excess in it so it would top off the mold if any more leaked out as it cured.Unfortunately, I got a little impatient and pulled the syringe out about an hour later, before it was completely cured and the "plug" for the hole pulled out with it because it was still soft. It didn't hurt anything in the end, other than to leave a slight dip in the finished surface instead of a plug that could be cut flush. Lesson learned.I couldn't wait to see how it came out. The instructions say to wait 5 hours before demolding, but I did it after a little more than 4. It was perfect! (other than the dip mentioned above). In order to completely remove it from the mold I had to stretch it around parts to get it loose. It's quite durable! I had to stretch quite a bit and it showed no signs of tearing. There was a lot of flashing from where it had leaked into the joints of the mold, but that was easy enough to trim off. They even supply a tool for doing so, though I didn't try it.It picked up every detail of the mold, including of course the layer lines. I had no trouble with it sticking to anything. Even the rough layer lines of the PLA. It came out of the syringe and mixing cups easily too, just by pulling on it.I have to say I am thrilled with how things turned out. I will definitely be using this stuff again if I need to make more squishy parts.

I've seen others give negative review of this product due to incorrect use related to using the silicone with 3D Printed models. For FDM printers, the silicone will do a great job, no extra work needed. For resin printed 3D objects, extra care has to be taken to prep the models for use with the silicone. Most importantly, you need to properly wash the model with isopropyl alcohool. You can not use any isopropyl alchohol that you've previously used to clean other prints. If you do, your molds will come out a guey mess like others using the product have noted.Use isopropyl alcohol that you've never used before to clean the resin print. Once washed, spray it properly with more alcohol. The key here is to have no leftover resin on the model - if this uncured resin (invisible to see) comes in contact with the silicone it will contaminate it and the silicone will never harden and the contact surfaces will be a guey mess. Once you've properly washed the printed resin model with alcohol, wash the model with hot water and dishwashing liquid (not in a dishwasher), using a toothbrush to get rid of all the alcohol. Then rinse the model with water so that there is no dishwashing liquid (or alcohol or resin) left on the model. Put the model in water and cure with UV light for at least 20 minutes. Keep the model in the water for a day (preferably under direct sunlight - while still in the water). Once done, let it dry properly - do not use a hair dryer for this. Blow air on it or let it dry naturally, you can also dry with a cloth or paper towel. Only once it has completely dried is it ready for use with the silicone. Hope this helps someone.
