Siraya Tech Defiant 15 Platinum Silicone Mold Making Kit, Food Safe, Shore A 15 Hardness, Ideal for 3D UV Resin Projects, Easy Curing, No Coating Required, Durable, Versatile, 2.2 lb Set Clear

Let me start out by saying I rely on silicones and casting products to make a living. I have tried several 15-30 durometer silicones and had always had strange problems with them. Having said that, this silicone did not have any of the issues that other *more costly* silicones had that were comparable. The fact that I have also had zero cure inhibition issues when used in conjunction with elegoo ABS like 2.0 (that is my go to resin for my 3D printer) is just like the cherry on top of an already great silicone. It degasses extremely fast which speeds up production, while having ample work time when making smaller molds. I have used both the 15 and 25 duro varieties and have been equally impressed with both. One last thing worth noting is that when I had used other comparable platinum silicones that are a 1to1 ratio I seem to get a considerable amount of shrinkage. This has not been the case with the siraya tech silicone, even when using the molds repeatedly in a heated pressure pots I have not had any noticeable shrinking in any of my molds. Lastly, in my opinion it is very affordable, to be honest at its price point I didn’t expect to be this impressed by it. It is very seldom that I use a product that checks all the boxes, I wouldn’t change a thing except maybe making the product available in larger kit sizes and expanding the durometer range to include maybe a 45. It has quickly become my go to silicone for smaller molds that require some flexibility. These are my views and opinions and your mileage may vary.

Really high quality silicone. I don't use silicone often, but this has been my go to. Hardens well, and is bubble free. Mixes easy and the cure time is pretty quick.

Works great! Came quick

I'm confused, this is at least as hard as my 25 silicone from this same brand

It actually works! I've wanted to make silicone molds of resin prints for years but the dreaded cure inhibition has foiled every attempt. Follow instructions on sirayatech web site and it should work. Tried several resins and only when I skipped the UV cure under water was there a small amount of inhibition. Love this stuff wish it was more economical. I've tried both hardness's.

I really wanted this to be a "how-to use it review" but instead I'm going to tell you "how to save your time" by not buying this regular albeit overpriced silicone expecting it to be more compatible with resin prints. In the instructions they tell you to use their resin cure it underwater, which works fine for solid parts. but when you have cavities, even with multiple washes, curing stages, scribbing, doesn't matter, still won't cure. In my case there is a 2mm gap that's 20mm long and 30mm deep, that is facing upward, it won't cure. I increased the size of the cavity to 4mm gap, still won't cure. I've remade this mold 4 times now, reprinted the master 3 times, tried minimal to maximum cleaning, curing starting at the rated 30min scaling up to hours, with the same results. wasted time, dashed expectations.

Buena calidad. Ya he utilizado esta marca con otros productos. Estoy satisfecho con los resultados obtenidos. Recomiendo Siraya Tech.

Works good

Absolut großartig. Keine negativen Reaktionen mit 3D-Resin (solange man sich an die Vorgaben beim vorbereiten der 3D-Drucke hält) Das weiche Silikon macht es sehr einfach Abformungen heraus zu holen. Kann dieses Silikon nur wärmstens empfehlen!

Top spul geen bubbels en snel hard

Love!! It’s a bit pricey, but it works with the Siraya tech fast resin without cure inhibition, or waiting for off gassing in my experience. I cured my prints submerged in water for 30-60 minutes, then polished and created a mould almost immediately. I have not tried this with other resins, however. It captured all the small details in my dice design beautifully. Definitely recommend!

Erfüllt meine Erwartungen.
