HOW TO PREPARE A FILE FOR 3D PRINTING
CHALLENGE
SUGAR LUMP CHALLENGE
SUGAR LUMP CHALLENGE:
To complete your Essentials you will need to draw a 3-dimensional object in Rhino to a very specific criteria, process it through the CAM software, and print it.
The criteria are:
It must be no bigger than 18mm square, but also no smaller.
Your object must extend to the boundary of an 18mm cube, There must be a point of your object that touches each extent.
It must include three surface modeling commands; ExtrudeCurve, Revolve, and Loft.
It must have an 18mm x 18mm x 1mm base (what you design takes up the 17mm above)
RHINO BASICS:
To 3D print, you need a digital model. You can make this in any 3D modeling software. We recommend Rhino3D (Access to Help) |If you have already completed your laser essentials then you will have experience with 2D curves. 3D printing requires surfaces (that are later converted into meshes, more on this later). It is easy to generate surfaces from your curves. Below are some examples.
PREPARE YOUR FILE
Below are a few basic steps to get your file ready for processing.
1 Check you model
Use the Command show edges to see any obvious problems with the model. For example, the below polysurface is not 'Watertight' as it is missing a surface the 'Naked' edges of the missing surface are highlighted in pink.
The solution is to build a surface. In this example using the command cap works (this will only work if the naked edges are in the same plane)
2 export
To 3D print the digital object you will need to export it as a mesh. Select the object you want to print, go to 'File' - 'Export Selection' choose the file type .stl (Stereolithography). Name the file 'year'.'month_SugarLump_Name (For example 24.01_SugarLump_DavidScott).
If you need help or would like your file checked please come to the CAM lab between 12:00 - 13:00 Mon - Fri and a member of the team will happily help.
