Educational technical illustration for a 3D printing troubleshooting website. Side-by-side diagnostic comparison: left shows severe under-extrusion with thin sparse lines and gaps in printed walls; right shows a partial nozzle clog with curling filament and inconsistent extrusion from the nozzle. Clean engineering infographic style, warm off-white background, black and graphite printer parts, subtle purple and yellow accents, no text, no logos, no brands, clearly illustrative.
