PETG, also known as polyethylene terephthalate glycol-modified, might come off as a hefty term. However, it’s the most common and regularly used kind of plastic around the globe.<\/p>\n\n\n\n
This type of plastic is always on the rise and is demanded everywhere. You can find them in genuine plastic materials, utensils, toys, containers, bottles, and so much more.<\/p>\n\n\n\n
But most importantly, it’s a recyclable plastic that can be injected or blown into materials so that they can take shape, make bents, cuts, and more. In the world of 3D printing, it’s pretty exciting and necessary to know how it’s done.<\/p>\n\n\n\n
Let’s dive in to see a tad bit more on PETG stringing<\/strong>, 3D printing filaments on PETG, how to fix and avoid errors during these prints, and more!<\/p>\n\n\n\n During 3D printing for PETG, you must place special care into it so that the result isn’t destroyed by stringing.<\/p>\n\n\n\n The good news is that this issue isn’t entirely too rare, and what’s even better is that it can be controlled and rectified. Stringing usually occurs because of the high melting temperature and high viscosity levels.<\/p>\n\n\n\n This excessiveness results in drips from the nozzle when the operator moves. Therefore, it is deposited in the model as strings.<\/p>\n\n\n\n Related: Fix PLA Stringing<\/a><\/p>\n\n\n\n Honestly, dealing with the results of 3D printing with PETG can be overwhelming for too many reasons. But when worst comes to worst, the results become entirely useless. This is why you must counteract a scenario before you begin printing.<\/p>\n\n\n\n Now, this is where sample models of 3D printing can save your day and eliminate any errors that you might face. Sample models are smaller products where you can visibly see the mistakes; thus, rectifying and comprehending the errors are easier.<\/p>\n\n\n\n Moreover, sample prints come in handy while working with demanding filaments and mostly if you’re inexperienced with 3D printing overall. With proof prints, you can’t waste much material. Therefore you end up saving lots of expenses too.<\/p>\n\n\n\n This comes even handier if you’re working with larger orders. For these cases, it’s vital that the settings must correspond a hundred percent to the model and filament’s requirements.<\/p>\n\n\n\n Related: PETG vs PLA<\/a><\/p>\n\n\n\n Since we’re all here to learn how to perfect 3D printing for PETG, let’s see how we can keep it controlled and minimize stringing.<\/p>\n\n\n\n The temperature of the nozzle being used during 3D printing significantly influences the filament’s viscosity. Materials like PETG can be heavily manipulated because it becomes too fluid when the melting temperature is reached.<\/p>\n\n\n\n On the other hand, if the temperature is too high on the nozzle, you will have unwavering strings. If that’s the case, a test print in constructing a temperature tower can be beneficial. This will help you find the nozzle’s perfect setting with just one shot.<\/p>\n\n\n\n Consequently, you should also practice being cautious during this stage. If you lower the temperature too much, it could expand the structure’s surface. Therefore, having a balanced temperature is an absolute necessity.<\/p>\n\n\n\n This method is also great at preventing PETG stringing. If the nozzle moves fast enough between the two points, there’s lesser time for the filament to drip out. This has a higher advantage comes from working at higher temperatures, as the PETG liquefies even faster.<\/a><\/p>\n\n\n\n It’s ideal for boosting up the speed gradually; for instance, ten millimeters per second works excellent. This will also enhance your opportunity to adjust the values precisely of the printer’s characteristics and the model. You can also determine your desired speed by giving trials with test prints. If the value you’re working with is ideal, there will be no visible stringing.<\/p>\n\n\n\n Raising the retraction could minimize the threads in a model. Most of the time, this turns out to be quite effective.<\/p>\n\n\n\n The phenomenon works because the extruder motor pulls the filaments out of the nozzle during the course of the retraction. In this manner, counteracting the dripping process can be done by raising the retraction by one millimeter.<\/p>\n\n\n\n And the speed shall be boosted by five millimeters per second. However, these can only serve as basis levels. Thus, you can adjust the setting until you get your desired results for the model and printer. It’s also highly beneficial to reduce the traveling distance.<\/p>\n\n\n\n This setting lets the printer decide how far along should the printer’s head travel before the filament retracts completely. With lower values, you can ensure zero stringing even with shorter distances.<\/p>\n\n\n\nPETG Stringing Issue:<\/h2>\n\n\n\n
