Ultimaker 2 Print Configurations
This page contains 3d printing configuration information specific to the Ultimaker 2. For preparing any print for this printer, make sure that you select "Ultimaker2" under "Machine" in Cura. If that option is not present, you may need to follow the Cura configuration instructions for this printer, or may need to install the latest LulzBot version of Cura.
The default PLA material settings work, with one modification: after selecting the loaded material, go to the "Material" settings page, and then "Customize", and change the filament diameter setting to 3mm. Most objects will print well on the heated glass bed.
Glue may be helpful for long, thin prints that don't have very much surface area to stick them to the bed. If you choose to use glue, here are some helpful tips:
- Use only a very little. One or two swipes with the glue stick across the bed should do it, then take a wet paper towel and wipe it down. This should leave a thin, practically invisible film on the bed. If you have clumps, your print will not go down correctly.
- Cleaning glue off the bed: water and a paper towel will clean glue off of the bed between prints.
- Dried glue that comes off the glass bed can get inside important parts of your printer and cause problems. While canned air is generally good for cleaning printers, if you have dried on bits of glue inside your frame and spray in with canned air, the glue can get caught in the Z-screw, extruder, pulleys, or timing belts and have a negative impact on your printing.
Because of contraction due to cooling, ABS tends to lift away from the glass build plate. This is worse for square corners; round objects rarely lift. In Cura, specify a raft around your object. This way, the raft will (possibly) lift but your object may stay flat. When the build-plate is still cool, paint a thin layer of ABS paint (glass jar) onto the clean glass build plate. The dried ABS paint will further anchor your object to the build plate. Recommended settings are ......

Use this only on the Ultimaker. The material is FDA approved for food contact applications. Set the filament diameter to 1.75mm, bed temperature = 70C, nozzle temperature = 245C. In Cura, set the layer thickness to 0.2mm. A data sheet can be found amphora_pds_en.pdf here
