The printed Enterprise is 3.5" long, 2" wide, and 1" deep. I used gold colored ABS filament to make the print. The printed Enterprise and the OpenSCAD view of the model are shown in the attached photos.
I made this at TechShop.
Step 1: Materials, Tools, and Software
- 1.75mm width Gold ABS filament from Octave Systems
- The 3D printer I used was a MakerBot "Replicator" at TechShop.
- A set of small hand cutting tools to remove excess support structure material from the model. I used the "3D Printer Tool Kit A" from Octave Systems. You could use an Xacto knife and dental tools as well.
- A small pair of needle nose pliers also used to remove support structure material.
Step 2: Design in OpenSCAD
Basically what the OpenSCAD script does is:
- define the saucer section (two cones attached to each other on the wide ends)
- define the engines (a sphere half embedded in the front of a cylinder, a cone attached at the rear, and a rectangular solid at an angle to connect to the main body)
- define the main body (a sphere half embedded in the front of a cylinder and a trapezoidal solid attached to cylinder and the saucer section)
After I was satisfied with the design, I created a STL file of the design using the "Save As..." option in OpenSCAD as shown in the last screenshot.
The OpenSCAD script and the STL file are attached.
Step 3: Making the 3D Print
The next three screenshots show various views of the model in the ReplicatorG software. It took 1 hour and 52 minutes to print the Enterprise.
Step 4: Remove Raft and Support Structure
To clean up the model, I gently pulled off the raft. I then removed as much of the support material as I could by gently tearing it off. For the most part, the raft material easily pulled off. I used needle nose pliers to remote any stubborn pieces and then used the cutting tools to remove any additional excess material.
