Make better 3D-printed signs, lights and gifts

Real problems beginners meet, shown in the slicer: prints that do not stick, stringing, warping, supports, bridges, models that do not fit, broken meshes and slow prints.

3D Print Not Sticking to the Bed? 7 Fixes for First-Layer AdhesionWhy a 3D print lifts, slides or never sticks to the build plate, and the order in which to check it: clean plate, first-layer height, bed temperature, brim, fan, speed and part orientation, with real slicer screenshots.3D Printing Overhangs and Supports: When You Need ThemHow steep an overhang can be before it droops, what the support threshold angle really means, tree versus normal supports, and the settings in PrusaSlicer and Bambu Studio, tested on a four-angle model.Bridging in 3D Printing: Why Bridges Sag and How to Fix ThemA bridge is plastic printed across a gap with nothing underneath. See how slicers mark bridges, what the warning “long bridging extrusions” means, and which speed, fan and design changes stop sagging.Holes and Gaps in the Top Layers of a 3D Print (Pillowing) and How to Fix ThemWhy the top surface of a print looks rough or has gaps over the infill, and which settings fix it: top solid layers, top shell thickness, infill density, cooling and flow. Real values from PrusaSlicer and Bambu Studio.How to Fix Stringing and Oozing in 3D PrintsThin hairs between parts are caused by plastic leaking while the nozzle travels. Check wet filament, temperature, retraction and travel moves in this order, with real PrusaSlicer and Bambu Studio settings.How to Stop Warping and Corner Lift in 3D PrintingWhy the corners of a flat or long print curl up from the bed, and what to change: brim, bed temperature, part-cooling fan, orientation, drafts and the shape of the model itself.Model Too Big for Your 3D Printer Bed? Rotate, Scale or Cut ItWhat to do when the slicer says the model is laid over the bed boundary: rotate it, check the units, scale it, or cut it into pieces with the cut tool and join them again. Steps shown in Bambu Studio and PrusaSlicer.Open Edges and Broken Meshes: How to Fix 3D Model Errors Before SlicingWhat “open edges”, “non-manifold” and “errors detected” mean in a slicer, how to see them in PrusaSlicer and Bambu Studio, and how to repair a broken STL.Thin Walls and Tiny Details Not Printing? Know Your Printer’s MinimumWhy a thin wall disappears or comes out thicker than you modelled, how the nozzle and line width set the minimum, and which wall thickness to design for. Shown on a test with five wall thicknesses.Why Is My 3D Print Taking So Long? Measured Effect of Infill, Walls and Layer HeightWe sliced the same 60 mm cube ten ways in PrusaSlicer and recorded the estimated print time and plastic use. See which settings change the time, and which ones barely matter.
