Print quality issues
Print not sticking to the build plate
When you experience problems with the adhesion of a print to the build plate, the following things can be done:
• Ensure that the correct material settings and adhesion method were used (see chapter 5 Operation).
• Re-level the build plate to ensure the distance between the nozzle and build plate is correct (see chapter 4 Set up for
first use).
• Check the Ultimaker Cura settings that were used and try printing with one of the default Ultimaker Cura profiles.
Under-extrusion
In its simplest form, under-extrusion is when the printer is unable to supply the
right amount of material. Your Ultimaker 2+ is under extruding when you see
missing layers, very thin layers, or layers that have random dots and holes in
them.
Under-extrusion can have several causes:
• Use of low quality material or wrong material settings
• Feeder tension not set correctly
• Friction in the Bowden tube
• Small particles of material in the feeder or Bowden tube
• A partial clog in the nozzle
When your Ultimaker 2+ is suffering from under-extrusion, it is advised to take a
look at this page for detailed troubleshooting instructions.
Warping
Warping occurs due to material shrinkage whilst 3D printing, which causes the
corners of the print to lift and detach from the build plate. When plastics are
printed, they firstly expand slightly but contract as they cool down. If material
contracts too much, this causes the print to bend up from the build plate.
When your print is warping, make sure you have done the following:
• Level the build plate correctly
• Apply a thin layer of glue to the glass plate or use an adhesion sheet
• Use the correct temperature settings
• Use one of the default Ultimaker Cura profiles
To troubleshoot this issue in more detail, take a look at the Ultimaker website.
