There can even be differences between spools from the same manufacturer if the fabrication process isn’t carefully controlled. Every manufacturer has its own blend hence the different optimal extrusion temperatures. Ideal printing temperatures are a starting point as you should find out which one is the best for your combination of filament and printer. This depends on the extrusion temperature and the part cooling. Then there’s also the question of what happens once the material is deposited and how strongly it bonds with the previous layer. Getting the temperature just right lets you push plastic through the extruder but without uncontrolled dripping. With polymers, there is a temperature range where it starts to flow, and it becomes less viscous the higher the temperature is increased. In thermoplastics melting temperature isn’t fixed as it is with water for example. Filaments are made from different polymers that have different melting temperatures so extrusion temperature depends on what filament you choose. The most common 3D printing technology today is based on melting plastic filament and depositing in an organized manner. Then simply adapt the print settings of that profile to suit your needs. Use the Standard Cura Profiles as a starting-off pointĬura offers different profiles for most filament types (PLA, ABS, PETG, TPU, etc.) and these come with settings that generally work quite well. Below you’ll find an explanation for each of the parameters that you shouldn’t ignore. Once you master the main settings you can continue with the vast number of advanced features that the different slicers offer. When starting with 3D printing you should only really focus on a few parameters.
