Before you start working with the material, you should be well prepared for the job. The XTC-3D has a very short curing time after mixing, and therefore after mixing the components it is best to begin coating the model with the resin immediately. You should also pay attention to such details as how you are going to hold the model, or what is it going to be attached to. The material takes at least two hours to dry, so holding it by an appendix which you have just covered with resin is out of the question. Although it may seem obvious, keep it in mind from the start – otherwise you will have to paint the model in parts (which is sometimes inevitable anyway).

Preparation – Materials should be stored and used in a room temperature environment (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. Measuring and Dispensing – You need to be accurate in measuring for XTC-3D™ to cure properly. Parts A and B can be measured by either volume or weight. Dispense proper proportions of parts A and B into clean plastic, metal or wax-free paper containers (do not use foam or glass cups).

The more solvent added, the longer XTC-3D® will take to cure. Cured material will be more flexible. I wonder what PLA you are using as I have never experienced your problem; I am just wondering if you are using a cheap PLA which is leaving some residue on the finish. XTC-3D is an epoxy resin that mixes by volume rather than weight, which is a lot easier. A very small amount of XTC-3d is needed to coat a 3D print. With 1oz of mixed XTC-3D you can cover three Phil’s. Now, let’s get started: 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.

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. Just use acetone on 0.06mm layer prints, its a lot easier, less messier and has no problems with sharp corners either. But this XTC 3D might be better for 0.1 mm and lower layer prints Smoothing Surface – granular surface texture can be smoothed by applying a second coat of XTC-3D™ (for glossy finish) or lightly sanding for matte finish. Thinning XTC-3D™ for Coating Starch / Powder Printed Parts - Viscosity can be lowered with acetone or denatured alcohol to penetrate porous parts. Mix Ratio

Also for this part I printed a jig which fitted on the bottom so that could rotate the part as I coated it without getting my hands on the part itself. Painting – XTC-3D® can be painted and/or primed and then painted with acrylic enamel paints. For best results, lightly sand surface prior to painting. I have had similar problems and the issue seems to be dirt or some other material that prevents the surface from wetting properly. The coating seems to brush on OK, but then patches thin as the resin retreat from these regions, and the spots appear. Its seems the surface tension of the XTC-3D is exceeding the affinity between the XTC-3D and the surface being coated. Same reason oily spots on a glass surface prevent water from forming a smooth sheet. Or spray paint fails to coat dirty patches.Measuring and Dispensing – You need to be accurate in measuring for XTC-3D® to cure properly. Parts A and B can be measured by either volume or weight. Dispense proper proportions of parts A and B into clean plastic, metal or wax-free paper containers (do not use foam or glass cups). Opened containers of resin, hardener, silicone or chemical release agent, unless found to be faulty or defective. One issue was that whilst smooth it did not look great to the end customer so we added some of the XTC colouring to the mix. As you can see the 3D printed layer lines etc. have disappeared.
