Tired of seeing layers on all of your prints? 3D designer Bethany Weeks demonstrates how you can use polymer clay to smoothen out your 3D prints and leave behind an easily paintable surface. 3D printing is a tremendous tool for expressing and bringing ideas to reality, but with Fused Deposition Modeling (FDM) technology, the results are usually plagued with noticeable layer lines that take away from the final product. Thankfully, there are a few ways to smoothen out a print. But the usual methods have their flaws. Chemical smoothing involves toxic chemicals that are highly flammable, sanding requires a fair amount of time and physical effort. So what is the best way for a 3D printer enthusiast to eradicate layer lines? How about polymer clay? In a new Instructables post by designer and 3D printing enthusiast Bethany Weeks, the maker shares an interesting post-processing technique that smoothens out the surface of your prints. By using polymer clay, you can coat your 3D print and bake it in an oven, giving the object a clay sculpture-like appearance. There are a few pitfalls to keep in mind. For instance, the part will likely shrink during the baking process, but this can be acco...
