UM3 - No build plate adhesion after cleaning

Posted · UM3 - No build plate adhesion after cleaning

I have been chasing my tail lately in regards to build plate adhesion. Recently I cleaned the stock glass build plate with Windex as it was covered in finger prints following moving the printer across town. And this is where I believe everything when horribly wrong and continues to do so. I am attempting to print thin parts in PLA with a customized default profile and absolutely nothing sticks to the build plate, I can sometimes get a portion of the first layer down (although it is suffering from under extrusion). If I let the print run through I end up with a glob of melted plastic stuck to the underside of the nozzle and a clean built plate. Previously, before I cleaned the glass plate, the print profile was working just fine (even after the move) with the odd part not adhering which is just how it goes. I have tried to wash the build plate in dish detergent, scrub it with clean paper towel and lastly this morning tried using a magic eraser on the build plate to scrub anything off. Any suggestions for cleaning the build plate and making my prints stick again (I have tried the UHU stick supplied but this quickly dried onto the build plate and wasn't tacky at all). I have used spray adhesive in the distant past and this has worked well but leaves fine parts a little messy so I am hoping to avoid this.

    I clean my glass plates with soap and water. After drying I wipe the plate with alcohol.

     

    But I apply always a very thin layer if glue too. It is much safer that everything sticks really well.

     

    I made a short video, because I think most people use the glue stick in a wrong way.

    Thank you you for the tip, I will give it a go and will be heading off to watch your video right after this is sent. I think that I should grab some IPA and give the glass a good wipe and polish with a clean paper towel. I did do a bed levelling last night and that did help with the under extrusion issue. After levelling the first layer of my print looked great, the second layer is when everything peeled off of the plate and remained on the nozzle.

    Yes, in my experience cleaning with window-cleaner sprays destroys bonding. Just like any soap would. It seems they all leave traces of soap on the glass.

     

    I clean with isopropyl alcohol to remove grease, and then a couple of times with pure warm tap water only.

    So our company prints exclusively in Poly Carbonate which is one of the hardest things to get to stick.... but I have had only 1 failed print!

     

    My routine is after every print I clean the glass with rubbing alcohol and one of those blue paper shop towels (they don't lint), making sure to turn the towel over and inside out several times to ensure I get the glass CLEAN!

     

    Then before printing while the glass is COLD apply a thin even layer over the entire build plate (or at least the area of your print plus some). 

     

    Then just let the printer run and do it's thing.

     

    After the print is done let it get completely cool and you should be able to remove it will little to no issues. By letting it cool completely the plastic shrinkage breaks the bed adhesion for you so you don't have to hardly pry on it at all.

     

    Rinse and repeat!

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
