A dirty print bed is the most common reason first layers fail, yet most people reach for isopropyl alcohol too often and scrub too hard. The counter-intuitive truth: aggressive solvent cleaning often makes adhesion worse over time by stripping the microscopic texture that filament actually grips. What you need is a surface-specific cleaning sequence that…
Most 3D printing adhesion problems come down to picking the wrong first-layer helper. For the majority of PLA and PETG prints on a modern heated bed, a skirt is all you need, and a brim is your go-to when parts start lifting at the corners. A raft is the nuclear option—effective but wasteful—and you should…
If your first layer won’t stick at all, curls up at the edges, or breaks loose halfway through a print, the bed temperature is often the first setting you’ll want to revisit—but only after you’ve ruled out Z-offset and cleanliness problems. The right bed temperature keeps the first layer bonded until the part cools, and…
Best 3D Printer Bed Surface: PEI vs Glass vs Garolite For most people printing PLA, PETG, and ABS, a textured PEI spring steel sheet is the best bed surface you can buy right now. It delivers reliable adhesion while the bed is hot, releases prints almost effortlessly once it cools, and the flexible steel makes…
When a 3D print lifts off the bed at the corners, you are dealing with warping—a specific adhesion failure where the edges of your part curl upward during printing. The plastic cools unevenly, contracts, and peels the first layer away from the build surface. The fix is rarely one thing; it is a sequence of…
A perfectly level bed means the nozzle maintains the same small gap across every point of the build surface—not that the bed is literally horizontal to the ground. The goal is a consistent first-layer height, typically between 0.1 mm and 0.2 mm depending on your nozzle size and layer height settings, so filament squishes evenly…
If your first layer won’t stick, peels up mid-print, or looks like a frayed rope instead of a smooth ribbon, your Z-offset is almost certainly wrong. Z-offset is the vertical distance between the nozzle tip and the print surface at Z=0, and a calibration error of just 0.05 mm can turn a reliable printer into…
A first layer that won’t stick is almost always one of four failure patterns: the filament never grabs the bed at all, the initial lines go down but peel up immediately, corners and edges lift mid-print, or the whole print breaks free partway through. Each pattern points to a different root cause, and guessing wrong…
