Customers are satisfied with the performance of the epoxy. They mention that it works great, the foam brushes work really well for application, and it adheres to PETG very well. Some say that the product is definitely worth the try and that it worked very well without any pinhole leaks.

"...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!..." Read more

"I use XTC 3d to smooth out print lines. It works very well for this purpose. I used it most recently for a 1/4 scale figure print (pictured)...." Read more

"...heads and water features, if coated inside and out, work very well without any pinhole leaks...." Read more

70 customers mention49 positive21 negative

Customers like the quality of the epoxy. They say it's amazing, good stuff, and of high quality. It does a good job at filling in the imperfections and is easy to sand. It has a perfect cure time, and it cuts priming time in half.

"...Seriously??? And of course no refund available because this stuff is toxic and can’t be returned." Read more

66 customers mention47 positive19 negative

Customers like the ease of use of the lab supply. They mention that it goes on easy, comes with good instructions, and saves them time. They also say that it saves time by not having to sand large prints.

"...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...." Read more

"...It works, but it takes a lot of time." Read more

80 customers mention51 positive29 negative

Customers are mixed about the appearance of the coating.

Some say that the coating is easy to tint with acrylic paint or food coloring, while other say that small details are rounded off or covered entirely.

"MY LORD. This stuff is super cool!I did not use this to coat 3D printed parts. I personally use it for cosplay purposes...." Read more

"...The result is a hard clear surface that you can sand or paint if you so desire." Read more

"...If you don't do this, it dries smooth but lumpy and takes a ton of sanding to look good...." Read more

42 customers mention21 positive21 negative

Customers have mixed opinions about the ease of cleaning the product. Some mention that it dried flat and required almost no sanding, while others say that it ends up bubbly, uneven, and requires scrubbing. Additionally, there is no cleaning this off anything if you spill so be very careful.

"...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...." Read more

"...I recommend you get a decent paintbrush instead. The foam brush soaks up too much and deteriorates too quickly, but a paint brush can be cleaned out..." Read more

"...No joke its bad stuff. Sanding is relatively easy but it goes through paper faster than any other product I've been using...." Read more

"...with the brush for the full 20-30 minutes, but still I had pretty bad streaks and bubbles and rough spots all over my print...." Read more

24 customers mention8 positive16 negative

23 customers mention14 positive9 negative

Customers are mixed about the sturdiness of the product. Some mention it's durable, shiny, and adds an element of strength, while others say that it'd completely solid and unusable. The mixing cup that is included is flimsy and not very strong, and the product winds up being bubbly and uneven.

"...It mixes very easily, lasts quite a while on the plate, goes on well, sands easily, and has almost no smell...." Read more

"...The mixing cup that is included is flimsy and not very strong...." Read more

"...It does add an element of strength that I like. I use it on thin points and it builds a stiff layer to help it. Will buy again." Read more

"...on the level of print lines you're dealing with, and you've got a very sturdy and smooth surface for paint and you couldn't tell it was a PLA print..." Read more

Works as advertised.
I use XTC 3d to smooth out print lines. It works very well for this purpose. I used it most recently for a 1/4 scale figure print (pictured).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.
Thank you for your feedback
