![]() ![]() Ensure there are no greasy fingerprints on the glass plate though. ![]() If you print with PLA it’s not always necessary to use glue (only with bigger objects), so mostly a clean glass plate will work. Tape can damage and thus cause an uneven print surface.įor Ultimakers with a heated bed it’s advised to either keep the glass plate completely clean or to apply glue to it. If you have an Ultimaker that uses blue tape as a print surface, make sure to replace it once in a while. from your fingers) on the build plate, as that will only lead to worse adhesion. There should be no traces of oil or grease (e.g. Regular bed leveling is important for a good first layer Print surfaceįor good adhesion it is important that the print surface is smooth and clean. Therefore we advise to always re-level the build plate when experiencing issues with the first layer of your print. In both cases this will lead to a bad first layer, which might eventually lead to adhesion problems. On the other hand, if the nozzle is too close to the build plate it can prevent the filament from extruding from the nozzle. If the distance between the nozzle and build plate is too big, your print won’t stick properly to the glass plate. Bed levelingįor printing it is very important that the first layer is nicely squished into the glass plate and sticks well. Also the fact that the print head fans are usually turned off during the first layer helps in this case. The default settings on the Ultimaker and in Cura should be fine for this, but with some materials it could help to slightly increase the bed temperature. For PLA we for example recommend a temperature of 60☌, while ABS needs a temperature of 90☌. This way you ensure the first layer of the print doesn’t cool too much, due to which it could shrink a lot. When you have an Ultimaker with heated bed it’s important to use the correct bed temperature. This page describes some tips on improving the adhesion of your print to the build plate. You will especially notice this behaviour when printing ABS, which has a relatively big shrinkage. Plastics have the tendency to shrink when cooling down fast (some plastics more than others), which could eventually lead to loose and deformed corners of your print. Warping basically happens because of the material properties. It could either mean that the first layer just doesn’t stick well enough or that the prints gets loose due to “warping” of the plastic. When you’re experiencing difficulties with prints sticking to the build plate, there could be a few things going on. ![]()
