Traditional 3D modeling begins with CAD software, offering precise, mathematically-defined models with infinite detail. However, a shift is underway: slicers—once mere tools for converting models into printer instructions—are evolving into powerful design environments. Modern slicers now support advanced features like Arachne slicing, organic supports, embossing, fuzzy skin, part splitting, and infill manipulation, enabling users to shape not just the outer form but internal structure and function directly within the slicer. Through case studies like a custom box lid and a Bahtinov mask using infill hacks, this talk explores how slicers are becoming intuitive, printer-aware modeling tools that challenge the necessity of traditional CAD workflows. Can we now model entirely in the slicer? The lines are blurring.

What if you could turn a CT scan into a 3D website? This talk walks through the full pipeline—from raw DICOM data to interactive browser visualization. Using Python libraries like pydicom, opencv, and pandas, we process and convert medical images into .nrrd format, applying computer vision techniques to clean up artifacts. Then, with Three.js, we render the scan in real-time on the web. This session explores how open tools bring medical imaging out of the clinic and into the browser.
