BBDINO Silicone Mold Making Kit, 2.42lb Super Elastic Liquid Silicone for Mold Making, 3h Fast Cure Platinum Molds Making Silicon Rubber for Casting Resin/Silicon/Candle/Soap Molds

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. Follow up almost 2 years later: Still happy with the quality of the results. While I did finally tear one of them, it had taken quite a bit of abuse before that point. When I poured the first molds, I had quite a bit of leftover mix, so I stuck it on the shelf and forgot about it until the other day. I expected that after having been opened for all this time, it probably wouldn't work very well anymore. Much to my surprise, the new pours came out just as good as the first ones. I didn't expect such a long shelf life, but I'm happy to be surprised.

This was my first time using silicone for anything, and I have to say - this stuff works great! Needed to make candle molds of an oddly specific size so I glued the existing candles to the bottom of plastic cups, mixed this stuff up at the 1:1 ratio (tip from the net: pour, mix, pour into a second container, mix again, THEN pour into your mold), filled the cups, and after eight hours I cut the cups away and the wax candles slipped right out of the cured silicone. Perfect molds, no air bubbles, tested them out the next day and they work great! AND they’re elastic enough that I can roll the lip of the mold down to get a grip on the candle without worrying about tears. (For my purposes any color would have worked, but definitely a fan of the jade color too. No color leeching either!) Definitely going to order another batch, what you see in the video used up *just* about all of it - 12 small candle holders, 4 tall ones, and a wee bit of overpour. PLENTY to use on a larger scale project!

Super easy to use, 1:1 mix ratio. Came with good instructions. No smell which is a great thing for me. I used it for candle mold making. Made an exact copy of my object.

Self degassing is a joke. This stuff appears to be smooth on the outside but was full of micro bubbles inside the mold where it counts. This stuff is also not meant for large molds. Made some decent sized molds and it took an extreme amount of effort to remove my items I was molding as the bigger the mold, the less flexibility you get. I probably should have realized that before I purchased but gave it a shot anyway. I did give one star as it’s easy to mix and no odor but I most likely won’t try this again. If you do purchase, make sure to degas or you WILL have micro bubbles inside. It was also very greasy inside the mold. I let it sit for 24 hours and mixed it very precisely so that shouldn’t have been an issue. Edited: 1 out of 5 of my first batch of molds (the molds in the previous review) did come out perfect so I decided to purchase more to try this again. This time my molds came out perfect. I don’t know what went wrong with the first batch as I weighed and measured it out very precisely, must have been a defective batch. I’m changing my rating to a 4 as all the subsequent batches from different bottles came out right. I will add, my molds were quite thick and I cut pieces that had cured correctly of the bad mold (not the parts that didn’t) and layered them in the gaps in my box to keep from having to pour so much and the new batches bonded to them perfectly without gaps. That kept me from wasting so much in the dead spaces from the irregular shapes of the items I was trying to mold.

I love this stuff. I use it to make molds for candle making. I love how flexible it is. Great product!

気泡もすぐに抜けて商品はとても良いものです。が、購入先の評価をしっかりと確認されて購入をされた方が良いと思います。いい加減な業者に当たることがあります。

De muy buena calidad, fácil de usar.

I did make a few moulds but quite expensive.

Great product

Fantastic product and really easy to use. I wanted to make some custom silicone moulds for a project I’m working on. It has a 1:1 mix ratio, so it’s simple to measure out the two parts. They mix well and need about five minutes of stirring. Once mixed, you pour it into the mould container—it’s a nice thick consistency and pours smoothly. The mixture produced very few air bubbles, and none appeared in my finished moulds. I was making small to medium moulds, and they seemed pretty well set after an hour or two, but I left them for about six hours before fully demoulding. I’ve used the moulds several times now with no issues—no cracking or wear and tear. I would definitely recommend this product
