In chapter 5 lesson 14, you’ll learn how to design for additive finishes like powder coating, which protect your parts and enhance their appearance. Jake explains how these coatings add measurable thickness to both internal and external surfaces, affecting fit and tolerance.

You’ll also learn how to account for coating buildup on holes, tabs, and slots, when to include hanging holes for coating application, and how to handle hardware during finishing. By the end, you’ll understand how to prepare your parts so powder coating and other additive finishes look great, fit correctly, and last long in the field.

What You’ll Learn:

• How additive finishes like powder coating protect and enhance parts
• How coating thickness affects part dimensions and fit
• Why to plan clearance for holes, tabs, and slots
• How to add hanging holes for coating application
• How to protect hardware and threads during finishing
• Why additive finishes are the final step before assembly or use
