Recognizing CAD features and editing them
In the previous section, we briefly touched on the find features command, which is unique to direct modeling. In this section, we will dive a little deeper into this feature and highlight its strengths and shortcomings. We will also utilize this feature with an example dataset in order to edit a CAD file we import with DFAM principles in mind.
As 3D printing has become more mainstream, we need categories to refer to a certain group of 3D printers based on their category. At the time of writing, there are seven categories of additive manufacturing:
- Material extrusion
- VAT photopolymerization
- Binder jetting
- Material jetting
- Powder bed fusion
- Direct Energy deposition
- Sheet lamination
There are multiple material extrusion methods, but probably the most common one is Fused Filament Fabrication (FFF). As some of the early patents for 3D printing started expiring after 2002, FFF technology has been going through...
