They will help ensure that the first layer will stick to the bed. Even with ABS, any other layer that comes after the first layer won’t need that much adhesion and you will not need it to be sticking to the bed or the build plate. I'm a fan. Active If you are printing Prusament PETG, check the temps and speeds.  I find that 240 works for me and that globbing happens if it is not hot enough.  Make sure you selected Prusament PETG in the filament selection in Prusa Slicer and not one of the other PETG profiles... Make sure your live z is good with a first layer test and also, with the nozzle at temp, clean off the nozzle with a brass brush to remove the stuff that accumulated on it already before trying again. If your bed is far below the glass transition temperature and you’re having trouble with your print not sticking, increase your bed temperature in 5°C increments until the issue is resolved (staying below the GT temp). – Try This! Make sure the print bed is level. First layer PETG not sticking to print bed Last Post RSS cbethea73 (@cbethea73) New Member. On the other hand, if they don’t stick to the bed properly, you will end up with under adhesion issues and the part won’t even get off the ground, so to speak. The petg just sticks so beautifully to it. I'll have to see how it holds up over time. Apart from that, you can also utilize the bed leveling feature of your printer to get that first layer to stick well to the plate. We also participate in other affiliate programs. The powder-coated surface is less susceptible to permanently bonding to PETG or TPU/TPE, but care should still be taken when printing those materials to avoid damage to the build surface. Such a glass bedded thin layer can be a boon for many printed parts. So long as it's not on the glue edges for a prolonged period, there's probably little risk of damage. With a fresh piece of paper towel, and very clean fingers, dampen the towel with 91%+ alcohol, and wipe the bed side to side moving back to front, like you're painting it with alcohol. I just got my i3Mk3S last week and was merrily printing away.  I printed out around 40 pieces until I ran into this problem.  When printing the first layer, the first piece printed will go down ok, but as the extruder moves to the next piece, the perimeter layers of the shape are not sticking to the bed and getting gummed up around the nozzle.  So, by the second or third shape, the print goes completely bad.  This is using PETG and default settings in Slic3r (240/85 first layer temps).  You can see in the picture, the hex on the left is the first one which looks ok, but as it goes to the right, you see the layers get worse and then unusable by the last one.  I have changed no settings between when my prints were good and this, so I'm not sure what's going on. You can also use these tapes for ABS as well and they would take care of the problem and would also give good and clean and even sure shot results, time after time. As a matter of fact, glue sticks, hair spray, and various other sticky substances tend to work pretty decently if everything else that you have used has failed. Tim is correct and his answers above are a succinct summary of the steps to correct adhesion issues which is what your picture is showing.

But here the thing to remember is that over adhesion can mean that your prints will stick to the bed that they may break once you try to pry them loose. The most common reason for PETG parts to warp or lift during the print is due to insufficient bed adhesion or an incorrect nozzle height. I'm using Prusament and the problem isn't with it sticking.  The problem is that the first layer is NOT sticking.  It's peeling up and globbing on the nozzle like in the picture and the first layers aren't viable at all and I abort the print.  Can't figure out why since I had printed a ton of parts earlier and hadn't changed any settings.  Cleaned the bed multiple times with either acetone or alcohol or Windex.  None of it made any difference.  If I print more than one object on the bed, the second one will not lay down a good first layer, and oftentimes the first part won't lay down a good first layer. Albeit having said that, it certainly does not mean that PLA would always adhere to the printer bed, as and when you want. You can try different types of this stuff to make the perfect build. Dry it. If PETG filament globs onto the nozzle and gets dragged around instead of sticking to the bed: Make sure you have the right bed surface for PETG. If the 3D printer is too cold, the print won’t adhere as such. It is always very important that the very first layer of your 3D print is always very strongly connected to the printer’s build platform so that the remaining portion of your 3D print can be built on this foundation.
