Download page and settings description here. A diameter of 1.9 mm is recommended. Maintain retraction distance comparable to PLA, around 6 mm. 1.4 Initial Layer HeightBasically, PETG is different from ABS as well as PLA: We advise retreating from your print bed in 0.02-mm increments until you obtain the first layer elevation just right. A guide value is 50 mm/s. Die Bett-Temperatur habe ich auch 10-15 Grad höher als bei PLA. Defective parts are replaced and you can check everything for its condition. So you can save yourself the trouble of making all the adjustments if your nozzle already has a defect. We can only strongly recommend that you limit your support retraction. This tape will give you the exact same advantages of using blue painter's tape, but may not have the exact same amount of bond. From this value you can experiment in peace until you find the right setting. Basically, PETG is different from ABS as well as PLA: We advise retreating from your print bed in 0.02-mm increments until you obtain the first layer elevation just right. However, cleaning your 3D printer is not difficult at all and does not even take very long. If you pick to make use of glass, utilize a slim layer of hairspray, adhesive stick, or specialty bed adhesive. 3-5 °C) and look at the results. The perfect Cura settings for your Ender 3 ... PETG prefers a shorter retraction distance, ideally around 4 mm. He is happy to share his experience with each new article. The dust is caused by the extruder gear rubbing against the filament. As you can imagine, the retraction speed is the speed at which the extruder pulls the filament out of the nozzle and the Bowden tube. This is typically in millimeters per second (mm/s). Actually, this equipment can print with a huge selection of products. This will be enough approximately every three months. You'll find the Ender 3 is an excellent device to print this product with as soon as you get the print setups dialed properly. In our opinion, the best setting is “Within infill”. Since the Ender 3 only has one nozzle, leave these at the default settings of 16 mm and 20 mm/s respectively. One of the few common issues that we see with PETG is stringing. If it is deactivated, you will not find the other settings at all. PETG: This filament has comparable printability to PLA while still having high warm resistance as well as elasticity under pressure. Treatment of the Ender 3's print bed with blue painter's tape is the most effective and also most convenient method to get PETG to have a safe and secure bed bond along with ease of removability. But if you want You can find the STL on Thingiverse at this address: Thingiverse Learn how your comment data is processed. Seems it is an art form to perfect the petg anti-stringing settings. ... From the specs the Ender-3 nozzle can go up to 255 degrees, and the bed can be heated up to 110 degrees. Official Creality Ender 3 V2 Upgraded 3D Printer with Silent Motherboard Meanwell Power Supply Carborundum Glass Platform and Resume Printing 220x220x250mm ... Retraction enabled Retract at layer change Retraction distance 6.8mm ... but not in filament. This fusing can be so strong that it gets rid of portions out of the glass bed, permanently damaging it. It’s a good idea to play with these settings to find the best ones for you, to do this you can find retraction test prints on Thingiverse. ... (UM2 is around 70cm) it uses smaller retraction distance. I replaced the priming part of the start gcode with: I also reduced the final retraction in the end gcode from 3mm to 1mm so that the filament is left in a position where it doesn't require a lot of advancement to start priming, comparable to what you get after loading filament manually. If you are having stringing problems when printing, you should first of all make sure that your extruder is cooler to protect the filament and make it run more slowly. That’s why you should stick to small nozzles if you don’t like stringing. If there is no dust, you can leave the settings as they are or increase the speed. If you set the maximum retraction number, you can also protect the filament from damage. Without threads or other defects. The less often this happens, the better the final quality of the filament and thus the quality of your 3D product. So for good printing results it is better to set a lower speed here. If you've tried numerous various retraction sizes and also can not get it ideal, try differing retraction rates. With a maximum retraction number of 10, your filament will definitely be well protected. It is best to do this once a week, because it sticks together quickly. Don't hesitate to e-mail us with any questions or inquiries, we would be happy to answer your questions. If you want to get the best possible results in 3D printing, you need to relieve the nozzle during printing. In this way you protect your filament again. Its popularity and the small purchase price additionally ensure that it is often bought and thus a large online community is available. With a metal brush, you get the hotend nice and clean. There are of course other possible causes for stringing in 3D printing. So make sure that your nozzle has been manufactured cleanly and is still intact. If you do not get perfect results with any of the methods described below right away, you should get a test object for stringing. As you can see, these worths are very comparable to those of PLA, for this reason, the popularity of PETG. Preventing these strings requires precisely calibrated retraction settings, so make sure to adjust your retraction … Between adjusting the printing temperature, bed temperature, printing speed, and retraction settings, it may take you some time before you can find that “sweet spot” where you get to enjoy all the benefits of PETG without running into so many problems. PETG is notorious for adhering to the glass so well that it merges to it. Besides many test devices, Martin now has his third own 3D printer running and prints as a hobby for friends, family and himself. Bed Temperature.

With unclean materials, it is no wonder if your print fails or you have to deal with stringing.Â. A damp brush can help you to clean the extruder from filament residues. For PETG you should choose a shorter retraction of 4 mm, while for ABS you should choose 6, mm with a faster retraction speed of 40 mm/s. To do this, you disassemble all the parts you can remove and clean them thoroughly. These objects are small, don’t waste a lot of filament and test the settings using the worst case approach.An example would be the “Basic Stringing Test” by Loohney on Thingiverse.com (link).
