Petg Boogers, Therefore, i suggest at least a coated brass nozzle. Hey, I just wanted to share my experiences with printing PETG on the X1C, maybe some of you are having issues with it like I… Step 4️⃣: PROFIT 💵 If you’ve ever fought moisture bubbles or layer boogers, you know the struggle’s real 😂 💬 What’s your PETG storage hack? ⬇️ Drop it in the comments so we can steal—I mean, “learn from”—it. Even if it is just petg strings still a speed and extrusion problem. Mar 31, 2023 · I have mostly amazing prints with PETG (mostly thanks to Thrawns PETG issue thread) but every once in awhile there’s artifacting/blobbing/surface holes. I can see the boogers building up on the nozzle and they eventually come off randomly in the print and cause issues at times. Mar 5, 2025 · When printing, I’m constantly getting boogers which snow ball and get pushed around by the extruder as it prints often causing problems with the print, sometimes getting stuck in the print itself creating unsightly large (dime sized) boogers of PETG ooze. It’s very similar to T-glase in terms of looks, but it prints better than normal PETG. Learn how to improve print quality and reduce the appearance of unwanted filament strings. Jan 19, 2023 · The primary factor that can cause PETG to bubble during printing is the absorption of moisture by the filament, which presents itself as bubbles once the water comes into contact with the high temperatures of the nozzle and releases pressure. As PETG blobs and PETG stringing are often related to the settings of your 3D printer, configuring your printer with the correct values will prevent these issues from happening again. I'm very experienced with PLA but I've only got a few dozen rolls of PETG under my belt. On my Flashforge, unless I run the cooling fan full blast,overhang edges curl up and the part gets knocked loose. Top solid infill, supports slowed down to 25mm/s. I know its gloopy stuff known for things like collecting in globs on the nozzle. It’s a proprietary blend that acts more like ABS when printing (including its extrusion temperature) but without nearly as much warping as ABS. The finish of the first layer over the support is outstanding and compares well to what is achieved with a dual extruder printer using PVA for the support. ), post process finishing and part quality was ultimately the killer. For a PETG print, using PLA for the support interface works well and the opposite is also true. If I raise my nozzle much, I start to get the edges of prints peeling up… Help me not hate PETG. Read on for three easy ways to fix PETG stringing! RE: (Soluble) Support for PETG - Full interface layer have you tried printing with PETG yet? I just got my mmu2s last week, and I'm still trying to iron out a few issues, but I really like printing with PETG, and I too would like to find a support material. Heater block is leaking boogers when I print PETG I've had maybe 6-7 successful prints using PETG on this printer (some of them quite large) but the past two they failed due to massive singular layer shift (about 1 mm). Printer: Ender 3 Pro with bowden extruder PETG brand: Noname (the blue spool) and Giantarm (a white PETG which shows the same problems, so i dont think this is a material problem) Printing temp: 230°C for the initial layer, 240°C for the rest Bed temp: 75°C, i have a magnet sheet on the bed and i fear to destroy the magnetism if i heat up The Benchy looks good for the most part except for some boogers on the chimney And some stringing on the bow, near the front deck. Posting this here in case anybody else is Googling this problem. The print is otherwise fine, but there are so many imperfections because of this. PETG is stickier than PLA and really, really doesn't like to be over-extruded. It always boogers up like this on the nozzle and gets deposited everywhere. The best things you can do to minimize these issues: make sure e-steps is calibrated make sure flow is calibrated first layer calibration print with a silicone sock and make sure your nozzle is clean before you start printing. What's the deal with all the boogers? This is a brand new spool I just unwrapped. I had to switch to direct drive extrusion, and a plated nozzle to print it without getting boogers like that. My initial conclusion was that the notorious PETG boogers were causing this. This is by far the most frustrating filament to use. I need to print it HOT, or it will be brittle. I've tried: -Bed Leveling multiple times + Z offsetting. My untested theory is that petg boogers the nozzle up when it pops/crackles in hotend. Every once and a while I would get a brittle batch of PETG from prusa which sucked too. I tried replacing Problems with PETG stringing and blobs? Use these quick and easy fixes to reduce PETG filament strings, 3D print more and troubleshoot less! What is going on here? What's the problem? Petg its bone dry. A normal brass nozzle often loads up with "petg boogers" that randomly sluff off on your print, all burnt and crispy. This is the basic answer so keep on reading through this article to know the causes and a more extensive list of solutions that people have used to fix blobs/zits on 3D prints and first layers. As someone who prints exclusively with petg, your first layer too close. You want the absolute minimum amount of petg extruded that still gives you a good print. A solution for stringing and boogers with PETG on a Prusa MK3 tl;dr Turning off stealth mode fixed it. You can see moisture problems if you print slow and hear popping in from the hot end, and notice bubbly extrusion. As someone else said, drying helps, but it still happens for me with properly dry filament. I keep different profile for them for this reason. I experimented many different setting of printing to speed up or reduce cost but it still did not pan out. May 23, 2018 · Boogers on the first layer are usually due to a low LiveZ setting. I have been trying different settings with a very simple test model - and as you can see on the vertical face, there are lumps and bumps along the way 12 votes, 21 comments. On my Flashforge, I get pretty ugly pillowing and lots of stringing if I go anywhere near PLA or abs speeds while running PETG. Prusa has recently provided retraction over-rides in filament profiles for additional tweaking for specific filaments rather than only providing one system-wide default. If you have both issues. Using Priline Clear PETG (as dry as I can get it, it's gone through several hours of drying, and is being dispensed from a sunlu heated dryer box). The updated 3D-Fuel Pro PCTG profile for Bambu 3D printers is a solid improvement over the previous 3D-Fuel PCTG profile and the Generic PCTG profile. That would be the seam. I’ve not seen any of the PETG boogers or strings that accumulate over longer prints, and it has a higher glass transition temperature than normal PETG. Problems with PETG stringing and blobs? Use these quick and easy fixes to reduce PETG filament strings, 3D print more and troubleshoot less! Re: PETG Boogers or Blobs or Artifacts Another thought: make sure you're not using an infill pattern that results in the nozzle crossing over lines it's already laid down on the current layer. You might try a coated nozzle. Kinda the same with overhangs. Standard set up for elegoo petg. I'm always getting blobbing with my petg, even with a new roll of filament. Inland PETG from Amazon Started with the PrusaSlicer Generic PETG profile as a baseline 225C on all layers (looked fine on my temperature tower) PEI sheet coated with glue stick, because the textured sheet has adhesion problems on larger objects Infill, solid infill slowed down to 50mm/s. PETG, even though I seem to have read every article and tried many settings, I still get blobs, but only on vertical surfaces. I was printing some parts with Prusament clear PETG, using the standard Prusaslic3r settings. First layers, boogers, stringing, consumables (ie nozzles / heat breaks etc. One of the biggest pains in the ass with petg. printing PETG well requires careful tuning, you want to slightly underextrude and take other strategies to avoid oozing and building up boogers. (Even did it with BL Touch in the past) -Calibrating Esteps (they're perfect). Oddly, my Voron can go much quicker with PETG and has none of those issues. This project is for a local artist and i keep getting these boogers just like Mike is Discover the causes and solutions to the common issue of stringing in PETG 3D printing. Tension is correct. This has happened with all PETG. The right first layer setting for pla is too close and too fast for petg, petg wants to be deposited rather than squished, else you get a lot of blobs like pictured. Did Bambu Lab "pre-moisten" my PETG? **** UPDATE **** It would appear that the biggest problem was the first layer. As boogers and such get stuck to the nozzle, the plastic sort of spreads out all around the nozzle, and anytime a bigger boog or strand touches it, it just increasingly compounds the problem. It is based on an ATMEGA chip, which may struggle with high CPU load. My PETG prints keep clumping up and stringing. It happens once or twice on a 3ish hour print. IME, this applies to PLA and PETG. The Cura set-up needs to be just so. I think the root cause of the issue is the boogers that build up around the nozzle, it eventually builds up to the point where it starts colliding with the print, or just eventually falls off and ruins the rest of the print. PETG is a great material to 3D print with, even if it is a little stringy. Hi folks, I've spent several hours trying to fix this issue and would appreciate insight into why I can't seem to get consistent infill printing with PETG on my prints. -Tightening all belts/bolts/screws. RE: Persisting oozing blobs and stringing with Prusament PETG - What am I doing wrong? I've got the same issue going on with Hatchbox PETG which is also a good PETG. Could be that because of the speed you build up blobs from left over pressure of the extrusion process which clutter and burn. It prints nicer than eSun PETG and looks a lot better. Welcome to PETG boogers. PETG likes to stick to steel so that doesn't help. Not a petg thing but a too fast thing from my experience. I've been trying to get PETG working at least reasonably well. I went with a used grow tent 10x10 and just control temp/humidity in the room now; made life much easier. PETG is a special case, it's like printing maple syrup. It looks like the clumping comes from the infill. Let's see how to prevent it! The main problem I have with PETG, is obsession with maximum strength. It's not even the first layer, it's the layer after usually when it starts. First layer of PETG needs to be layed down without squishing (PLA needs to be squished to adhere properly). I get a lot of boogers in my petg. Question Transparent PETG Desiccant Drying Tray What's with all the boogers? This is my first PETG print using Bambu Labs transparent PETG. Sounds like your infill likely isn’t solid and all the mess is infill booger string that got pulled off the model and fell to the plate (stuck to the noz and got knocked off). On another roll of Inland PETG, I printed a Bed levelling & PETG boogers When trying to print with PETG, the nozzle tends to ooze during warmup. Try reducing yot extrusion multiplier a little first as it can affedt both situations. You can lower the extrusion multiplier until your layer lines are less “full”, it looks like your print is slightly over extruded, which will cause excess petg build up. I have HIPS, and I will probably try it with PETG once I get PLA to print without issues. self-adhesion is severe, aggrivating things like ooze. PETG is stickier, and the height for a good squish with PLA can cause the nozzle to dig in, resulting in the scraping that yields the boogers. Here are my settings. Aug 26, 2022 · I've found it difficult to completely dry out PETG once it gains moisture, although drying is a great improvement. This project is for a local artist and i keep getting these boogers just like Mike is Heater block is leaking boogers when I print PETG I've had maybe 6-7 successful prints using PETG on this printer (some of them quite large) but the past two they failed due to massive singular layer shift (about 1 mm). Going straight from the filament dry pack to a dryer that feeds filament straight to the printer has done the best. This works up until mesh bed leveling starts, then the 9 point check stomps the string that continues to ooze into a booger on the nozzle. Because PETG is very "gooey" and builds up on your nozzle and falls off at random places across your print probably. Problem: My infill lines are an inconsistent gappy/blobby mess, as you can see in the included picture. PETG doesn't like to be printed at 150 mm/s usually advised speeds are in the region of 50 mm/s. But this IIIDMAX PETG won't print a single print without completely going to crap by at least layer 5. What is a PETG blobbing or stringing? It refers to small lumps or hangings seen on the surface of a 3D final product. My favorite PETG thus far is M3D’s ABS-R (R = “replacement”) which, despite its name, is based on PETG. The infill blobs of doom. Just wondering how well does the Bambu resist the collection of PETG nozzle boogers when printing with PETG. PrintedSolid has it now and again. I just had to crank up the temp to 270c for petg and it prints like pla for the generic setting, also the fan was off in the generic setting so I turned that back on. If you are interested in seeing some of the best tools and accessories for your 3D printers, you can find them easily by clicking here (Amazon). the hotter it is, the more "boogers" I get, which are large enough to frequently cause my print head to skip out of place and fail the print. Problem: PETG is giving me insane booger problems. . I'll patiently sit there with my little brass wire brush and clean the strings off as they form. What am I doing wrong? Because PETG is very "gooey" and builds up on your nozzle and falls off at random places across your print probably. Quite the pain, but boy does petg make good springs and other rigid, but flexy parts. What is going on here? What's the problem? Petg its bone dry. Being a Newbie, to 3D printing, I started with PLA and PLA+…and feel pretty comfortable with printing with those. RE: PETG Boogers @pau-p If peters advice doesn’t help; If you have accumulated PETG on the nozzle my guess is that you have the first layer to tightly leveled. jhzwo, q9tel, pq6nrt, canbjy, sj5x0, 9bvg, pmth, 8ry5b, 7qhtd, wbj0r,
