Lifting off the print bed !!! Help please.

Posted · Lifting off the print bed !!! Help please.

I am new to 3D printing. I have having issues with print lifting off the print bed. Anyone had this issue and found the reason? I have the UM2 and I am using the Elmer's purple glue on the glass plate for adhesion. I am printing with PLA.

    Hi mkoening,

    I've also started my printing lately, and got some surprises when starting to print.

    First I used heat bed at temperature set to 60 deg. Celsius. (Yes, I'm using PLA as well.)

    I started by washing the bed, dried it and go, but as the model grow up it suddenly snapped off the bed and a lot of filament mess... etc. etc.  :)

    Well, I learned this the bed have to be "super" clean, no remains of fingerprints etc.

    After this learning, the model never come loose like that again.

    Then I learned a new lesson; my printing was never that good, especially the part of the model close to the heat bed.

    So I learned this here in this forum (thanks to Nicolinux:));

    I've stopped using the heat bed when printing PLA, just using glue stick!

    It stick very well to the bed glass plate and do not go loose, -but can be really hard to get off the bed.

    I do not know the "Elmer's purple glue", but the glue I'm using is the glue meant for using gluing photo into the "photo album". This is a glue stick and loose up easily in water, kind of like soap.

    Put a tiny layer where the print will sit, make sure to cover this place.

    I started printing at 210 deg. C as advised, but I'm now printing at about 192 deg C.

    You may find the correct temperature for your brand of PLA, I'm using Verbatim PLA.

    Edit: Forgot one important issue; level you heat bed very accurately, use a sheet of 80 g print paper (approx 0.15 mm thick).

    OK., Good Luck.

    First: check if your print bed is very close to the print head, when printing the first layer, so that the first layer is squeezed well into the bed. Otherwise, no bonding method will work.

    Then I recommend that you start printing with the default values for PLA: 210°C nozzle temp, 50mm/s, 60°C bed temp. These are a good all-round average. And fine-tune later on.

    For good bonding, I always wipe the glass plate with very salt water prior to printing:

    - First clean it with pure tap water only (no soap, because that reduces bonding).

    - Then moisten a tissue with very salt water, and wipe the glass plate.

    - Gently keep wiping while the water evaporates, leaving a very thin, even mist of salt stuck to the plate, almost invisible.

    This always works very well for me, since more than a year and 1000+ objects: I have no corners lifting, even not for very difficult objects (long, 100% filled, big chamfers).

    See the full manual with tips at:


    The advantage of the "salt method" is that salt water is very easy to apply, is cheap, and there is more than enough available in the world... :)

    Others have good success with applying wood glue dilluted with water (10% glue), and wiping that on the glass plate with a brush, and let it dry into a very thin almost invisible layer. And others prefer a spray can such as 3DLAC. But I have never used that.

    I have been having some prints lift off and producing the dreaded filament spaghetti too!

    I haven't been using the glue stick, just the heated bed and printing directly on the glass at 70C

    However, being it is summer and it has been humid this week, I am wondering if those conditions could cause the prints to pop loose?

    What material are you printing with as 70 is a bit hot for PLA

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
