Ultimaker Cura – Prepare (Slice) a Print
Use the adjustment tools to manipulate the selected part:
• Move: Move part in reference to build plate (enter values for x/y coordinates, or
drag triad arrows to move selected part).
• Scale: Adjust the size of the part by percentage or to specific dimensions. Leave
“Uniform Scaling” ON to maintain proportionality.
• Rotate: Rotate part about 3 axis to determine the best print orientation that
avoids unnecessary waste of supports and build time by determining the best
print orientation. You can rotate by dragging the colored rings of the rotation
triad. Be sure a flat face remains on the bed for print adhesion!
• Seek assistance from Makerspace staff if you are unsure of the ideal print
orientation.
• Support Blocker: Select areas where no supports should be, effectively
“blocking” the area off from support structures. Use this feature only if support
printing is enabled and certain regions should NOT have supports.

For general 3D printing, apply the following “Print Setup” settings:
• Extruder: Ensure “Extruder 1” is selected, Material is set to “PLA”, and Print
Core is set to “AA 0.4”.
• Print Setup: Use the “Recommended” configuration options.
• Layer Height: Use 0.2mm for general printing. Use 0.15mm or 0.1mm if
finer layer resolution is required (for example, printing screw threads)
• Infill: 20% for general printing.
• Generate Support: IF REQUIRED, enable with Extruder 1.
• Seek assistance from Makerspace staff member if you are
uncertain about need for support.
• Build Plate Adhesion: Enable for most prints.
• Print Preview: Preview 3D print with Print Setup settings applied.
• Click “Prepare” at bottom right corner of window to slice current print job.
• Set 3D view to “Layer view” to graphically visualize print paths and
individual layers. Everything in the view should be shown as “Extruder 1”
color. “Helpers” include build plate adhesion and support structures.

the part will print.
• Place staff approved (paid) NJIT Makerspace 3D Printing Information Card
in card holder.

Ultimaker 3 Printer – Remove a Print
• Wait for the glass bed to cool. The 3D printed part(s) are easy to remove when
the bed is near ambient temperature. If the bed is cool, the part can likely be
removed without use of any tools.
• Use a spatula. Gently work the blade of the spatula under the print at
approximately a 15 degree angle and slightly wiggle it back and forth until the
base of the print is released.
• Clean the glass bed. Remove any excess plastic and hair spray.
• Bring NJIT Makerspace 3D Printing information card to front desk to
approve and document Print Job Pickup.
• If Ultimaker printer maintenance or repair is necessary, or if a spool of filament
needs to be replaced, please contact NJIT Makerspace Staff for assistance!
