3D PRINTING

 

3D Printing:

3D Printing is a method of rapid prototyping in which objects are built (printed) layer by layer in an additive process.  Typically, the printing software slices a computer model (stl file) into hundreds of very thin horizontal layers.  The machine then prints (or fuses) those layers in succession one on top of the other, building the object from the bottom up. The Stuckeman School has one Makerbot Replicator 2X, one Makerbot Replicator 2 and Makerbot Replicator Mini available for student and faculty use.

Printing Basics:

  • Build a Well-Crafted 3D Computer Model: Sloppy computer models will undoubtedly have problems producing a physical 3d print. All of your solids must be solid and "normals" should all point in the same direction.  All of your surfaces must meet precisely.  Holes in surfaces make your model unprintable.  If you have an extremely complex model, be prepared to spend additional time repairing irregularities such as inverted surfaces. You model must be “water tight”. Geomagic is an excellent software for checking and repairing problem models. Geomagic is installed on the computers in 002 Stuckeman. We use Makerbot Desktop to prepare files to print on our Makerbot 3D printers. The software is installed on the computers in 002 Stuckeman, and you cal also install it on your personal computer. 
  • Scale Your Model: Make sure to scale your model to the size it will actually be printed. It is best to do this right in your modeling software.  
  •  
  • Evaluate Thicknesses and General Structure:  Be careful when scaling down a large model. If your model is a 10 story building for example, simply scaling it down to 1/32”=1’ is not a good idea.  In this case a 6” wall will be just 1/64” when printed... That is far too thin for 3D printing.  You will need to do additional work to beef up your structure. 
  • Exporting your File as STL, OBJ or THING 
  • Digifab Staff Can help you through the process the first time you use the Makerbots. 
  • You can check out a spool of filament from our staff. You are charged based on the weight of the filament you used when you return the filament.
