3D Printing Extra Credit

The 3D printing extra credit is given for designing your company logo in any CAD (Computer Aided Design) software of your choice and having it approved for printing by a 3D printing specialist. Your logo will then be printed on a first come first served basis (If EG cannot print your design due to time or material constraints you will not be penalized).

Specifications

Logos:

  • Maximum material usage 15 grams total
  • Logos must be integrated with your project in some way:
    • Pin worn during final presentation
    • Used as a part of your SLS model
    • Attached to robot during commissioning video
      • Add provided Lego technic beam model to your part to allow it to be connected to your robot (in important downloads)
  • Must be original content
    • Cannot simply be text
  • Initial STL file submission before the day of your Milestone 2 presentation
    • The 3D printing process can take multiple revisions, you are required to submit a first attempt by Milestone 2 but you will be allowed to make any modifications until the final deadline of Milestone 3. If you miss the Milestone 2 deadline, subsequent submissions will not be considered.
  • Final Submission by Milestone 3

Course Modificaton:

  • Maximum 1 Color
    • Maximum print size (11 x 11 x 9.8in)
    • Object may not be touched after the robot has started to run
  • Must meet with Prototyping Lab TA (RH223) to start print
  • Original Design
    • Must be different from other groups’ submissions
    • Will be judged by 3D printing TA’s and Professors
  • Must be .stl extension

Software

To design your logo you will need any CAD software as well as CURA. There are many options for software that can be used, the only necessary feature is that the software can export files as an STL (stereo lithography) extension. Some examples of these pieces of software are:

  • Autodesk Inventor – Free student edition
  • 123D – Free (Online)
  • TinkerCAD – Free (Online)
  • Blender – Free (Open source)
  • OpenSCAD – Free (Open source)
  • Solidworks – Available in NYU computer labs
  • Rhinoceros – Free for mac

To make a 2 color design you will need to save your logo in two separate STL files (one for each color). The two files are then imported into CURA aligned and the extruders are selected.

Design Considerations

Make a flat bottom: A large flat bottom increases the adhesion between the build platform and the part, keeping the part from shifting around during a print.

Keep overhangs close to 45 degrees: Each layer of a 3D print needs to be supported from below. You can avoid adding additional supports to a print if all the overhanging parts are at no more than a 45 degree angle from vertical.

Avoid thin walls and thin columns: Thin walls and column often do not come out well. The thickness of a thin wall should be a multiple of 0.35mm. Thin columns will usually come out distorted because they melt under the nozzle.


Submission

Submission of your team logo or SLDP modification will take place through the EG website using the “3D Printing Submission” tab of the left menu. DO NOT USE THE NORMAL SUBMISSION TAB. Your submissions must be .STL files.

If your logo has two colors, you must submit two STL files.

After your submission has been received, you will be contacted by a TA come to the Prototyping Lab to start your print. This process is necessary for your files to be printed.
