BBDINOSilicone Mold Making Kit, Super Elastic Jade Green Silicone, 1Gallon/140.8Oz, Ideal for Casting 3D Resin Molds & Silicone Molds, 1A:1B Mix Ratio

No lo he usado todavía, no he tenido tiempo suficiente… pero lo elegí porque se ve un producto de excelente calidad!

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.

Very high quality, be sure to measure perfectly to the letter though

Haven't tried it yet, hope it works for making wiggly spiders.

Really easy to use. I needed to cast the inside cavity of an item in order to make a precise fixture. This saved me time and money.

Great product, cures fast and works great if ?measurements are accurate

For the prize I would’ve thought it would’ve been bigger.

Good value
