Hey Ricardo,
bed adhesion with ABS is one of the ancient plagues of 3D printing. There is a huge list of different ways to try to rectify this. Just to name a few, starting at the well known glue stick/hairspray, stick-on surfaces like kapton tape or BuildTak (who 3DHubs actually has discount codes for), through more involved ways with ABS/acetone slurry smered onto the bed, to elaborate setups with heated print chambers. If you want to know more about each of those methods, I would recommend a well known website that allows you to search the internet, or telling us more about which methods you’re interested in. Elaborating on each here is just too time consuming.
Hope this helps.
Sincerely,
Jonas
You can also add a large brim to help. And make sure to keep a good temperature inside (adding a door and a top to the printer can help).
But first do what jonas advises, glue, hairspray abs juice are some paths to follow
Hey Ricardo,
I have the Ultimaker 2+ Extended which is very similar. Bed adhesion for ABS is something that tons of people struggle with, including myself. There are a couple of ways to hopefully mitigate your problems but since I don’t know your exact problem, this will be fairly general advice.
To start with, the Ultimaker’s default settings for ABS material is 260 degrees C for the nozzle and 90 degrees C for the build plate or platform. Not sure why the default is 90 but I’ve had much better results with models staying on the platform by raising that temperature to 110 degrees C. You can change the build plate temperature by clicking tune, scrolling down to build plate, and increasing the value to 110. Be sure to do this while the printer is heating up to have the best effect and don’t change it throughout the print.
Another idea that might help is building a simple enclosure for your Ultimaker. This would allow dramatically better heat retention and should help prevent any sharp changes in temperature that could cause warping and even your bed adhesion problems. There are a bunch of cheap ways and 3d printed designs to help enclose the unit.
You could also try changing the material that the ABS is adhering to. You could purchase Kapton/PET tape to place over the glass. These materials adhere very well and can withstand the high temperatures. After the print is done, let everything cool down before getting the print out. This will prevent tearing and allow you to reuse the tape dozens of times. If tape is out of the question, hairspray, slurry, BuildTak are all good alternatives to the standard glue stick.
Hope this helps!
Will
