Advanced 3D Printing

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".

This test should be carried out every time you print with a new material, as it provides one of the main printing parameter parameter of the filament i.e. the extrusion temperature. This test consists of a staggered part, in which the extrusion temperature will be varied progressively by 5 degrees. As each material has an optimum temperature, this test has different parts for different materials. These parts are practically the same, only the temperature range is different for an easier reading.
