For most people buying their first 3D printer, FDM is the right answer. It costs less to run, handles functional parts without drama, and doesn’t demand the chemical safety infrastructure that resin printing requires. Resin wins when surface finish and fine detail are non-negotiable—think miniatures, dental models, and jewelry masters—but for the broadest set of…
Dry filament wins for virtually every print you care about, and the single strongest reason is consistency: moisture-contaminated filament produces unpredictable extrusion, weak layer adhesion, and surface defects that no slicer setting can fully compensate for. If you are staring at a spool and wondering whether it is the source of your print problems, the…
Best PLA Filament Brands: Tested & Ranked 2026 PLA remains the most forgiving, widely available 3D printing filament, but brand quality varies enough to ruin an otherwise easy print. After printing hundreds of benchmark models across budget and premium spools, the brands that consistently deliver tight tolerances, low stringing, and reliable bed adhesion separate themselves…
TPU Flexible Filament Guide: Settings Tips & Best Practices TPU (thermoplastic polyurethane) is the go-to flexible filament when you need prints that bend, stretch, and absorb impact without cracking. The primary reason to choose TPU over stiffer flexibles is its rubber-like elasticity combined with surprisingly manageable printability on most direct-drive printers. You can print phone…
Most print-quality problems that get blamed on a bad nozzle or slicer settings actually trace back to wet filament. The fix is straightforward: store every spool in a sealed container with fresh desiccant, and dry filament before you print if it has been sitting out for more than a few days in average humidity. The…
PETG is the filament you reach for when PLA is too brittle and ABS is too frustrating. It sits in the sweet spot between the two: nearly as easy to print as PLA, with much of the impact resistance and temperature tolerance of ABS, and none of the styrene fumes. For most functional prints, mechanical…
Poor bridging and sagging overhangs almost always trace back to three things: insufficient cooling, printing too hot for the material, or asking the printer to span a gap it physically cannot handle at your current speed. The fastest fix is usually a combination of part-cooling fan speed and temperature, not a single magic slicer checkbox….
PLA is the filament every beginner should start with because it prints easily at low temperatures, doesn’t require an enclosure, and sticks reliably to most build surfaces without fuss. If you’ve just unboxed your first printer, PLA gives you successful prints while you learn bed leveling, first-layer squish, and slicer settings—without the warping, toxic fumes,…
PETG is the right default filament for most single-printer users. It prints on nearly any machine that reaches 240°C, delivers functional parts that survive drops and heat, and avoids the enclosure and ventilation demands that make ABS a non-starter in living spaces. PLA still wins for pure printability and decorative models, ABS remains the industrial…
The most likely cause of over-extrusion is an incorrect extruder steps-per-millimeter (e-steps) calibration, not a slicer flow rate problem. When your printer pushes more filament than the firmware expects, every print suffers—walls bulge, dimensions grow, and top surfaces turn rough and ridged. The fix starts with measuring what your extruder actually pushes versus what it…
