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. ## Frequently Bought Together - Smooth-On XTC-3D™ 20 Mold Making & Special Effects Silicone Rubber, 3D Print Coating - 6.4 oz - Rust-Oleum 260510 Stops Rust Automotive 2-in-1 Filler & Sandable Primer Spray, 12 oz, Gray - Assorted Grit Sandpaper for Wood Furniture Finishing (9 Inch x 3.6 Inch) --- ## 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.de/products/26052547-smooth-on-xtc-3d-3d-print-coating-and-smoothing-epoxy](https://www.desertcart.de/products/26052547-smooth-on-xtc-3d-3d-print-coating-and-smoothing-epoxy) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-06-23*
