Summary
This document is a technical report that outlines the importance of applying draft in the design for manufacturing (DFM) process, particularly in the context of molding and shutoff features. It explains that over 90% of 3D models begin the DFM process without sufficient draft, which can lead to complications during assembly and increased costs. The report emphasizes that draft should not be considered optional, as it is critical for part release from molds and achieving clean shutoffs. Specific draft application guidelines are provided, including normal molding draft targets and considerations for texture and shutoff drafts. The report also discusses the need for a mindset shift to incorporate draft during the modeling phase, rather than as an afterthought. It highlights the risks of ignoring draft guidelines and the potential for delays in the manufacturing timeline. The document concludes with a note on the evaluation of draft in conjunction with wall sections, indicating the next steps in the DFM process.
