Specifically, west systems epoxy?** A: I don't think there's anything you can do with this that you couldn't do with WEST System if you were determined enough, but it certainly wouldn't be my first choice for smoothing a 3D print. This stuff is very runny by the standards of epoxy, which lends itself to very thin coats that are less likely to build up in small crevices and wash out fine details. That said I'm sure it's also nowhere near as good an adhesive. **Q: Does this product effect the overall dimensions/tolerances of the print? Enlarge or shrink features?** A: It is a coating that adds appreciable thickness. It will enlarge all external dimensions and can cover up fine features if not used carefully. The effect on tolerance can be reduced by applying thin layers and sanding any remaining grain down. **Q: Type of paint suggestions?** A: Acrylic / enamel paints work best. **Q: This is a very random question, but can this epoxy also be used to seal cracks and knots in wood?** A: Our Tarbender may be a better choice for this - it is designed as a bar top epoxy, thought the XTC-3D will work as well, the Tarbender is a clearer material. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to work with *by M***. on 8 October 2024* Dries nicely ### ⭐⭐⭐⭐⭐ Juste bien doser. *by T***C on 14 April 2025* Très bon produit pour retirer les défaut d’impression 3d avant de les peindre il faut toute fois bien prendre deux dose du produit À pour 1 dose de B exemple 20ml À pour 10ml B ensuite bien mélanger.

This stuff is super cool!I did not use this to coat 3D printed parts. I personally use it for cosplay purposes. I coated my worbla and some foam pieces in this and it gave it a beautiful shiny smooth coat! It is great as a primer for Worbla as Worbla tends to have a very bumpy texture and with this you only need 1 or 2 coats to get a super smooth surface! It cuts priming time in half if you are used to using classic methods like coating it in 6-8 layers of wood glue! This took around 3-4 hours to cure up. I let it sit overnight. 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! ## Frequently Bought Together - Smooth-On XTC-3D™ 20 Mold Making & Special Effects Silicone Rubber, 3D Print Coating - 24 oz - 40 Pcs Foam Brush,1” Foam Paint Brushes, Wood Handle Sponge Paint Brush, Foam Brushes for Painting for Staining, Varnishes, and DIY Craft Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/87788138-smooth-on-xtc-3d-high-performance-3d-print-coating-644](https://www.desertcart.ec/products/87788138-smooth-on-xtc-3d-high-performance-3d-print-coating-644) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-06-09*
