Part 3 of 3: The Finishing Touches


Although your MarkForged Mark One 3D printer does all the heavy lifting, you may want to do some detailing – such as adding color or sanding – to your finished part. Remember, CFF™ printing liberates you from CNC machines and post-production chemicals. When we say finishing touches, we’re talking about detail work.

None of these recommendations are necessary or impact the usability or strength of your part, but if you’ve chosen a Mark One, we know you’re a perfectionist who wouldn’t settle for anything but the best output.


If you aren’t familiar with Rit dyes, get ready to unleash your creativity. This popular synthetic dye comes in 26 premade colors and can be mixed to create hundreds more. Nylon based parts absorb colors beautifully, so you can expect rich, vibrant results. The hardest part of dying your components will be picking the color. Simply prep your part by soaking it in warm water, dilute the dye, soak your part in the dye, rinse, and admire. Each dye comes with straightforward, but detailed instructors to ensure success. We’re confident you can handle it. As an added bonus, Rit dyes are also popular for dying clothes, leather, wood, and much more, so any leftover dye can be the start of a new DIY project … or two … or five


We know what you’re thinking. If Mark One creates strong, usable parts, why are we talking about sanding? It’s true. You don’t need to go through a post-processing procedure after you print your component. But, you might want to add a little extra smoothness or polish if you’re feeling especially ambitious. To get that high gloss, luxurious look and feel, you don’t need chemicals, just some low-tech 220-grit sandpaper and a cup of water. Use a generous amount of water on both your sandpaper and your part and polish to perfection.


In our last two posts, we discussed the value of using supports to achieve angles greater than 45 degrees. Supports are easy to use and even simpler to remove. Grab some grooved needle nose pliers and start with the supports closest to the part. To remove them, simply twist and pull. The support should peel off the part easily. If you see residue where the supports were, reread that second on wet sanding. Your part will be good to go in no time.
