Design for Process: Let the Machine Decide the Shape

Design for process is defined in C4.1.1. The question here is how you actually do it.
Every manufacturing process has rules it will not bend, so the process is not a service you send a finished design to, it is a constraint you design inside.
An injection mould must open, so the part cannot have undercuts and its walls must be drafted. Ignore that and the part will not release, no matter how good the design looks on screen.
Walls must also be a uniform thickness, because thick sections cool slower than thin ones and shrink as they solidify, leaving a visible sink mark on the surface.
So the rounded corners and even walls on a moulded product are not a style choice, they are the process showing through the design.

What Design for Process Actually Means

Manufacturing Techniques: Different processes like injection molding, 3D printing, or CNC machining have unique requirements and constraints.
Efficiency and Cost: Designing with a specific process in mind can reduce production time, minimize waste, and lower costs.
