Smooth vs. Rough

Caption

Unlike most commercial SLS platforms, Rice University's OpenSLS allows researchers to work with their own powdered materials, including specialized biomaterials like polycaprolactone, or PCL, a common nontoxic polymer that was used to print these tissue-engineering scaffolds. Researcher Ian Kinstlinger developed a method for smoothing the surfaces (left) of newly printed scaffolds (right) using vaporized solvent.
