Do 3D printers prefer particular topology? In case I'm not using the word quite right, I'm specifically wondering if I should make the faces in my models:
The most common file format in 3D printing is STL. This file format is using triangles only so when you export an object from your CAD application to STL then exporter has to transform all n-gon faces into triangles.
So answering your question:
- no - it doesn't matter as you usually use file format in which faces are triangles but
- yes - it matters as all your n-gon faces needs to be transformed into triangles
