Compatible with FDM, SLA, and SLS prints, it creates a durable, impact-resistant, and moisture-proof finish that is both sandable and paintable. With exceptional coverage—1 oz per 100 sq inches—XTC-3D streamlines post-processing, eliminating tedious sanding and vapor smoothing, making it the go-to solution for professionals and hobbyists seeking flawless, long-lasting 3D print finishes. ## Description XTC-3D is an easy-to-use epoxy top coat designed specifically for 3D-printed objects to smooth and protect your creations. With a simple 2:1 mix ratio (2 parts A to 1 part B), this resin self-levels when applied, eliminating the time-consuming process of sanding. It’s perfect for sealing 3D prints made from various materials, including PLA, ABS, and SLA. Just brush it on, and within minutes, XTC-3D fills in layer lines, giving you a flawless, professional finish. This versatile 3D print resin coating isn't just for aesthetics – it also strengthens your print by adding a durable shell that’s impact-resistant and highly durable. Once cured, XTC-3D is sandable and paintable, making it ideal for further customization. Whether you're using it for hobby models, prototypes, or industrial parts, this product is heat-resistant up to 150F (65C) and protects against moisture and abrasion. IMPORTANT: Use in a well-ventilated area. Wear gloves and safety glasses to avoid skin and eye contact. Store and use at room temperature (73F/23C). CAUTION: In case of eye contact, flush immediately with water for 15 minutes. If irritation continues, seek medical attention. For skin contact, wash thoroughly with soap and water. Keep Out of Reach of Children. Review: XTC-3D is hands-down a must have for anyone with a 3d printer. I usually print in ABS and follow the old "tried and true" method of sanding followed by vapor smoothing followed by final sanding before painting. XTC-3D eliminates the need for all that extra effort. To ensure a problem-free flawless finish: - Make sure that your part is clean. Use isopropyl alcohol, acetone, or whatever appropriate cleaner for your material to wipe your print clean - Mix the resin with the hardener in the exact ratio specified. Adding more hardener than necessary will only increase difficulty in applying it. Make sure that you mix it THOROUGHLY! I cannot stress this enough; You must mix it and continue mixing it until it becomes crystal clear. The longer you mix it, the better your finish will be, but the shorter your working time will be. I recommend mixing small batches at a time - you can always mix more if you run out. - Make sure that the ambient temperature is within the recommended range. Trying to coat your print when the temperature is below 70F will obviously increase the time it takes to fully cure. The mixing cup that is included is flimsy and not very strong. I made the mistake of mixing a batch and leaving it in the cup while applying it and the heat nearly turned the mixing cup into jellly and rendered it worthless. After mixing, pour it into another container, onto some aluminum foil, etc then wipe the mixing cup out with a shop towel, paper towel, etc. The foam brush is not worth the hassle - this holds true for ANY foam brush. 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 with acetone and reused several times. I was so impressed with this stuff that I ordered 24oz of it. Follow the directions, do the prep work and you will end up with repeatable flawless results. Review: It says "3D print coating" but it's really a brush-on, thin epoxy filler. I recommend you use a thinner mixture than what the instructions state to make. Doing so makes it a tad easier to work with this product. That's a good thing if you have an especially large printed object. Wet sanding is also recommended using progressively finer sandpaper. Overall, it's a good product, but not really needed with the newer generation 3D printers that actually print significantly smooth objects. ## Features - Epoxy Coating for 3D Printed Objects - Smooths and finishes 3D Printed Objects - Compatible with FDM, SLA and SLS prints; A little goes a long way: 1oz covers 100 sq inches ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01BKSLI9M | | Item model number | xtc3d | | Manufacturer | Smooth-On, Inc. | | Product Dimensions | 5.08 x 8.89 x 17.27 cm; 290 g | ## Images ![Smooth-On XTC-3D - High Performance 3D Print Coating - 6.4 Ounce Unit - Image 1](https://m.media-amazon.com/images/I/71PSKSVdNBL.jpg) ## Questions & Answers **Q: How is this better than other epoxy products? 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 ### ⭐⭐⭐⭐⭐ Review *by J***E on 7 February 2024* XTC-3D is hands-down a must have for anyone with a 3d printer.
