There was a problem filtering reviews right now. Please try again later.
It is important to note that this has no flexibility once fully cured. I tested this on a piece of EVA foam and it just about shattered like glass when I warped the foam. I didn't expect it to NOT do this to be honest. It is resin. It did not flake off. It adheres to the foam. it just left a bunch of cracks all over the place! On pieces that will not bend at all, like weapons or shoulder pieces etc, I think this works well to give your foam pieces a smooth glossy finish. I had already primed my foam with several layers of plastidip before I decided to experiment. Plastidip + XTC-3D does work :).
This is super easy to use! If you have used any sort of resin you will already have an idea. You have your resin and hardener. The instructions will explain how to mix but this comes with a handy little mixing cup with measurement markings on the side. It also comes with a foam brush and Popsicle stick for stirring. You will need to have more of these items handy for more than one use! The foam brushes work really well for application. Smooth-On offers online tutorial videos on You-Tube for this specific product. That helped a ton! Have tin-foil on hand to make a tiny pool to sit the product in. This increases the time to apply because letting in sit in the cup will cure up to fast and it'll be hard to apply. You wouldn't get a smooth application in this case!
I'd imagine this would also work well as a nice shiny finish over paint! But I find It is SUPER shiny once cured. Almost TOO shiny. If this is not the look you want, you can just simply buff it down by sanding lightly over it. I still prefer a Shellac coating as my final step.
With the Prime shipping this was the best deal I could find on this product! I highly recommend this!
It's very easy to use while keeping some safety steps in mind. I wear gloves and eye protection. It will thicken within the ten minute working time. You want to avoid leaving it in the cup to reduce heat build up and fumes. I like to spread it thin on a piece of cardboard or plate for the best working time. Mixing the right ratio is key to hardening like any two part resin product.
Drips will occasionally happen but they can be shaved or sanded down with little effort. I recommend thin layers to see how much detail you can preserve and still get most of the lines out . Overall I highly recommend xtc 3D for 3D prints. It fills layer lines very well for a smooth look once painted. It also provides a tough order coating.

It's not perfect though, but the marketing for it really, really overstates how easy and good it is. The #1 thing is that when you're applying it, you *must* follow the instructions and keep brushing over it until it finally starts to harden up. This takes ~20-30 minutes or so, during which you're just sitting there brushing and brushing and brushing. If you don't do this, it dries smooth but lumpy and takes a ton of sanding to look good.
If you just apply it, and maybe brush over it a few times, it looks like it's going on all nice and smooth, but when you come back an hour or two later (one positive is that it hardens up very nicely and quickly) the surface is going to be a bit like a golf ball. It's not runs or streaks (unless you slap tons of it on, getting drips is very unlikely), it just settles in a weird way, even if it's a second coat over an already smooth area.
On the plus side, it does sand very nicely with 220 grit sandpaper. 100 grit is a bit too much unless you do end up with a drip. The end result is going to be good, but the "eliminates 90% of finishing work" moniker really gives you the wrong impression. I've finished 3d printed items with a coat or two of filler primer and gotten excellent results in about five minutes of work, as compared to the hours I've already put into using this stuff.
Oh, and before you use it, buy a LOT of foam rubber brushes. Expect to use three or four of them over the course of a half ounce of material, especially with all the constant overbrushing you're going to have to do. After a few minutes the brush will start getting flimsy and if you keep using it, you'll end up with foam rubber bits on your surface. Michaels sells kits of a dozen or more of them for like $5.
It works, but it takes a lot of time.

Hay que mezclar cantidades muy pequeñas y extenderlas dejando la capa mas fina posible (evitaras gotas).
Se empieza a endurecer muy rápido, con lo que hay que andarse vivo para aplicarlo.
Me está gustando mucho.
+ can be used before painting to create a perfectly smooth surface to paint on
+ you can paint first (but don't add a wash or anything that accentuates layer lines) and then use xtc3d over, and it helps to hide the layer lines
+ easy to use, it is a liquid when combined in a 1:1 ratio and levels itself, meaning you don't get unsightly brush marks
+ creates a decent surface coat which adds a finished feel to products
+ looks expensive but works out cheaply. One layer of xtc3d seems to be as effective as 4 layers of clear nail varnish.
- if you get it on your hands, expect the feel/ smell to last for hours
- requires a flat, smooth surface underneath your items or expect to accidentally pick up bits of debris or paper on it. I use a clear smooth glossy plastic wallet.
- destroys your brushes very quickly. I bull bought loads of cheap paint brushes due to this
- if you mix the ratio wrong, it will never set properly. I found adding too much of the runny liquid part did this, so don't experiment! Just do a straight 1:1
- they should provide more than one mixing cup as it gets dirty pretty quickly from residue so means 1:1 ratio is harder to achieve
Love this stuff and swear by it. You aren't a real 3d printing expert until you have this finish :)
