Print Troubleshooting
Failed print? Find the cause and the exact fix: first-layer adhesion, stringing, warping, under-extrusion, layer shifts and the rest, in the order that actually works.
How to Analyse a Failed 3D Print From a Photo: A Defect-by-Defect Guide
To analyse a failed 3D print from a photo, start by working out when it failed, not what it looks like. A single photo carries more diagnostic information than most…
How to Fix First Layer Not Sticking in PrusaSlicer: The Real Fixes, in Order
Nine times out of ten, a first layer that won’t stick is a nozzle-to-bed distance problem, not a slicer flow problem — and here is the catch that trips up most people…
How to Fix First Layer Adhesion in PrusaSlicer: The Settings That Actually Matter
Nine times out of ten, a bad first layer is a nozzle-to-bed distance problem, not a slicer flow problem. So before you start pulling levers all over PrusaSlicer, get…
How to Diagnose a 3D Print Failure From a Photo: A Practitioner’s Decision Tree
To diagnose a 3D print failure from a photo, you read three things in order: what the defect looks like, where on the Z axis it happens, and which of four physical…
First Layer Adhesion Issues with PLA: The Real Causes and the Exact Fixes
Nine times out of ten, first layer adhesion issues with PLA trace back to just three things: nozzle height (Z-offset), an incorrect bed temperature, or a dirty build…
First Layer Adhesion Problems on the Bambu P1S: The Real Causes and Exact Fixes
When a first layer fails on a Bambu P1S, the auto-levelling is almost never to blame. The P1S probes a mesh of points and compensates for bed tilt and warp in software…
First Layer Adhesion Problems on Bambu Lab Printers: The Real Causes and Exact Fixes
Nine times out of ten, first layer adhesion problems on a Bambu Lab printer come down to one of five things: a contaminated build plate, the wrong Z offset, a bed that’s…
Layer Adhesion Issues: Why Prints Split Along Layer Lines (and the Exact Fixes)
If your print snaps cleanly along a layer boundary — a smooth, flat break that follows the horizontal lines — the bond between layers never fully formed. That is the…
Layer Shifting: Causes and Fix for Clean, Aligned Prints
Layer shifting shows up as a sudden horizontal step in the walls of a print — everything above a certain height is offset from everything below it, usually along the X…
Why Is My 3D Print Failing? A No-Nonsense Diagnostic Guide
If you’re asking “why is my 3D print failing?”, you’re almost certainly looking at one of a handful of repeat offenders: a first layer that didn’t stick, corners lifting…
How to Fix Stringing in 3D Prints: The Settings That Actually Kill the Wisps
Stringing is the fine cobweb of plastic threads left strung across your model when the nozzle moves between two points without extruding. It’s cosmetic, it’s annoying,…
First Layer Adhesion Problems: The Real Causes and the Exact Fixes
Almost every failed print shares one thing: the first layer didn’t stick. If that foundation fails, the print is already lost — everything above it depends on that…
