A definition
Design for manufacture is the habit of designing a part around how it will be made. A part that looks fine on screen can be slow, costly, or impossible to cut, mold, or bend. DFM catches that before a shop does.
Checks that move the price
Tolerances: a tight tolerance on a feature that does not need one adds machining and inspection time. Call out tight tolerances only where the assembly needs them.
Wall thickness and minimum feature size: thin walls warp or break, and tiny features need small tools and slow cuts.
Internal corners and deep pockets: sharp internal corners need small tools. A radius that matches a standard tool is cheaper.
Undercuts and draft: these decide whether a molded or cast part can leave its mold.
Material and finish: a common alloy or resin costs less and ships faster than an exotic one.
How 01 helps
On upload, the geometry service reads each part and the DFM agent proposes a process and a material. It flags tolerance problems, missing drawings, features no shop in the network can make, and cheaper design changes. Each flag links to the exact feature. You decide what to change.
