Amazon perfect layers4/2/2023 Print changing only layer height slightly and check the results until you find the perfect layer height for your specific project. More info on this topic in this article of ours Fine Tuning It is possible to emulate a larger nozzle by changing the extrusion width, but it is probably best not to exceed 125 – 150% of the actual nozzle size. Therefore, if you need a larger layer, it is advisable to use a larger nozzle. For PETG it is recommended to choose a thin layer to avoid delamination.Īccording to one study, the bigger the ratio of layer height to nozzle size, the smaller the gap between layers and the better the strength. The higher the layer height, the shorter the print time, but the less detail and strength. Layer height has a significant effect on print time, detail, and strength. If the brand isn’t listed, you can start with a generic PETG profile. Finally, there is poor layer bonding that can give some trouble, but it can usually also be managed in the slicer Enable Cura’s default PETG profile (Use it as a starting point)Ĭura has a lot of profiles for known brands built-in, so it is a clever idea to use them as a starting point and do small tweaks from there. Bed adhesion is also a concern because for some users PETG doesn’t stick well enough and for others, it sticks too well and it makes removing the model from the bed a pain. PETG can get really stringy but it’s only a matter of having retractions well-calibrated or quickly blowing the finished models with a heat gun to remove the thin hairs of plastic. I’ll go over each one of the settings in greater detail and discuss how to fine-tune them. With PETG you should watch out for stringing, bed adhesion, and layer separation or delamination, meaning that retraction settings are very important. It is important to turn off the fan for the initial layers and set the printing speed between 30 and 500mm/s. Now that we know the advantages of using PETG, let’s find out how to tune the printer’s settings in order to achieve the best results possible!įor printing with PETG, the be temperature should be set to 70+✬, whereas the printing temperature should be between 220✬-240✬. It also has a higher working temperature range, and it is more suitable for outdoor conditions. Some filaments also have varying opacities and can achieve good levels of transparency which can be good not only for aesthetic reasons but for projects that incorporate lights in them. Compared to PLA, PETG is tougher but softer. The modification makes it more suitable for 3D printers as it lowers its melting temperature and makes it easier to extrude. It is a modified version of the plastic that is used in soda bottles, for example. PETG is one of the most used polymers in 3D printing surpassed only by PLA.
