Unless you’ve ever owned a 3D printer, you might not know that quite often the objects they spit out contain small imperfections, be it little filaments that stick out, supporting structures that need removing, or stray plastic. Most people have gotten used to applying the finishing touches with sandpaper, razor blades or even irons, but these are all crude. The Retouch3D is a variable-heat pen made specifically for the task of, well, retouching your 3D prints. It can be set at the exact melting points of the various materials used in the printers, from PLA (polylactic acid), ABS (acrylonitrile butadiene styrene), resins or even wax. And then the heat can be varied in small increments so you can get exactly the kind of viscosity you’re looking for. Additionally, there are 5 interchangeable heads, allowing you to perform various tasks like removing, refining, or blending.
If you want yours, you’ll have to pledge $149 on their fully-funded Kickstarter campaign, and hope to get it by December, their expected shipping date.
