What are the top tips for slice FDM 3D models?

When slicing FDM 3D models, top tips include adjusting layer height for detail/speed, matching infill to part strength, using supports selectively, tuning print speed, and starting with presets. Layer height: Lower (0.1–0.2mm) for finer details (slower prints); higher (0.25–0.3mm) for faster prints (less detail). Infill: 20–50% works for most functional parts—more infill boosts strength but uses more filament. Supports: Only use for overhangs >45° to minimize post-processing. Print speed: Slow (30–60mm/s) for complex features to reduce errors; fast (60–100mm/s) for simple shapes. If you’re new, start with your slicer’s default presets for your printer, then tweak one setting at a time—this helps you track how changes affect prints without feeling overwhelmed.
