Slide 13 of 24

Notes:

Machinable or Cast Only? Design so machinable urethanes can be cast before unmachinable.

Cast only materials need to be in 2.5D (needs planing to get proper surface finish

avoid machining on soft surfaces to be used in high stress, high cycle applications (e.g. flexures). Machining may produce cracks that can propagate.

(later defines the fabrication order in processing)

2. Tool Size:

Width and length constrains designs. Design for manufacturability. Create parts with tool size in mind. Layers cannot be cut to depths larger than the tool length.
