XTC-3D High Performance 3D Print Coating - 24oz. Unit

Product Information

Adding Fillers: A variety of dry fillers can be added such as Cast Magic® or bronze or other metal powders, Glow Worm®, Quarry Tone® or Ure-Fil® powders. The maximum filler load is an amount equal to Part A by volume. Pre-mix filler with Part A before combining with Part B.

XTC-3D®is a protective coating for smoothing and finishing 3D printed parts. It does not melt plastic. Two liquids are mixed together and brushed onto any 3D print. Coating self-levels and wets out uniformly without leaving brush strokes. Working time is 10 minutes and cure time is about 4 hours (depending on mass and temperature). XTC-3D® cures to a hard, impact resistant coating that can be sanded, primed and painted. Adding colors and metal effects is easy. Removing Uncured Material - Scrape as much material as possible from the surface using a scraper. Clean the residue with E-POX-EE KLEENER™ available from Smooth-On, lacquer thinner, acetone or alcohol. Follow safety warnings pertaining to solvents and provide adequate ventilation. Preparation – Materials should be stored and used in a room temperature environment (73°F/23°C). Elevated temperatures will reduce Pot Life. XTC-3D™ Part A resin and Part B Hardener must be properly measured and thoroughly mixed to achieve full, high-strength, solid-cure properties. Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.

Notes

Applying a Release Agent – For applications where adhesion is not desired, a spray release Ease Release™ 200 available from Smooth-On may be used.

I'm way late to the party and signed up just to respond (I have a different 3D writer, but I wanted to contribute something I didn't see already posted (or maybe it was just in German). I certainly would not apply any thinner to the mix - not in the instructions! - but how much you load your brush may have an impact and of course is a personal decision, so one man's thin may not be another man's thin.No longer it matters the good that it was your printer 3D, with XTC-3D will be able to cover any defect of printing and soften all the surfaces. At present objects printed matter with ABS or PLA through technology FDM are not able to obtain surfaces totally sleek. At present the users of 3D printing to achieve better finishing in these pieces use knives , sandpaper , ketones So , all of them very little practical .From here it arises the competitive advantage of XTC-3D, since in so alone some minutes achieves soften and polish any surface. It achieves to delete 90% of the current work post finishing. This special coating full stretch marks and softens all printed surfaces in 3D. Adding Color - XTC-3D™ can be colored with UVO™ or IGNITE™ colorants. Pre-mix color with Part A before combining with Part B. Personally I will say follow the instructions and you will not go wrong; that includes measuring very carefully, to the instructions, the volumes you mix together. Interesting comment from @phantom on temperature; I have always applied it in a room with a minimum temp. of 20c.

The two "blobs" ringed in blue were a result of the "running problem I mentioned, now overcome. If you look at the strut on the right, at the lower left corner you will see some roughness on the edge which is a result of the scanned image. I think this is down to experience to get it right - On my first few attempts I was suffering on runs on non-horizontal surfaces (good finish where it did not run though)so I gradually loaded the brush with less XTC 3D until I got to a point where I did not get runs.

Acetone works only for ABS - so for PLA it would be Chloroform which is extremly dangerous because it is generating fumes.
