Advanced 3D Printing

Every common 3D printing problem solved: a complete index of troubleshooting and calibration guides - bed adhesion, stringing, extrusion, warping and more.

Rough walls, blobs, zits or elephant's foot? Fix over-extrusion: calibrate flow, check filament diameter, lower temperature, tune pressure advance. With table.

Gaps, thin walls and weak layers? Fix under-extrusion in order: clear clogs, dry filament, raise temperature, calibrate flow, check speed. Diagnostic table.

Layer shifts or ghosting in your 3D prints? What causes each - speed, belts, pulleys, vibration, rigidity - and how to fix them. With a symptom table.

Step-by-step OrcaSlicer and Orca-Flashforge calibration: temperature tower, flow rate, pressure advance and retraction in the right order for clean prints.

Stringing in your prints? Fix it in order: dry filament, lower temperature, tune retraction, optimise travel. With a diagnostic table for PETG, TPU and PLA.

Reliable print settings for PETG, TPU and ASA: nozzle and bed temperatures, speed, cooling, retraction and adhesion - with a quick-reference table.

Step-by-step Bambu Studio calibration: flow rate, pressure advance, first layer, input shaping and filament-specific tuning for Bambu Lab printers.

Calibrating the extruder is a crucial aspect of 3D printing with filament (FDM or FFF). If the extruder distributes too little material, the object will have holes or walls that are too delicate. On the other hand, if it dispenses too much material, it will create an issue called over-extrusion which will leave the piece with globs and strings, aka "Stringing".
