Prototyping Lead Time: Process Timelines and How to Reduce Delays

Prototyping lead time is often framed as a simple question: “How long will it take to get my part?” In reality, the answer is rarely determined by machine time alone. A prototype expected in days can easily take weeks—not because of production constraints, but because of delays in quoting, design iteration, manufacturability feedback, and supplier […]

Stage Gate Product Development: A Guide to Process Models and Best Practices

How modern hardware teams build and formalize the processes behind complex programs Stage gate product development is a structured approach that breaks hardware development into defined stages, each separated by decision “gates” where teams review design progress, trade-offs, test results, and risks before moving forward. This framework is widely used in engineering organizations to manage […]

The Top 10 Schedule Levers in Product Development (and When to Use Each One)

In product development, perfect upfront planning is nearly impossible. Product development is complex, creative, and unpredictable. This is why project development schedules are inherently fragile and must be managed closely to maintain forward momentum and avoid delays. A project timeline is set by making a long list of assumptions, many of which change as each […]

Jetting Defects in Injection Molding: Causes, Identification, and Prevention

How important is it to reduce jetting? (No—we’re not talking about private planes and celebrities.) Anyone who works with injection molding knows how crucial it is to maintain dimensional tolerances. But even after all that hard work, parts can still be rejected if they look bad. Jetting defects can occur even with the most advanced […]

Design for Serviceability: Engineering Products for Maintenance and Repair

Design for Serviceability (DFS) is an engineering approach that ensures products can be efficiently inspected, maintained, repaired, and upgraded throughout their operational life using accessible layouts, modular components, and standardized interfaces. Product development often focuses on performance and quality at launch, while long-term success depends just as much on how easily the product can be […]

The Top AI Tools Helping Mechanical Engineers in Product Design and Development

AI is reshaping how mechanical engineers and product designers work, as it moves from early skepticism toward practical adoption. Early AI models may have failed to account for constraints or produced unrealistic geometries, but recent advances have made AI a more trusted engineering assistant in product development workflows. AI still requires human oversight and validation […]

Keep the Assembly Line Happy: 10 Design for Assembly Rules to Live By

“Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away.” – Antoine de Saint-Exupery Your day isn’t going well when your boss quotes a French novelist at you. In this case, my design was rejected because my boss thought that it wasn’t “elegant”… What? Days […]

First Article Inspection (FAI): The Guide for Engineers and Manufacturers

In manufacturing, quality control is engineered and measured. Before production launch, you need proof that your design can be built repeatedly as intended. That data comes from a verification process called First Article Inspection (FAI). During product development, engineers put considerable effort into ensuring the design is near perfect—from dialing in dimensions and tolerances to […]

Adhesives for Assembly in Manufacturing: A Guide to Bonding Metal, Polymer, and Composite Components

Adhesive bonding is one of the most versatile and efficient joining techniques for manufacturing assemblies, especially when design constraints limit other options. Unlike mechanical fasteners that add weight and concentrate stress, adhesives create seamless joints that distribute loads evenly and reduce vibration. They enable cleaner aesthetics, dampen noise, and allow designers to bond metals, plastics, […]

Tabs and Slots for Sheet Metal Part Design

As sheet metal fabrication advances and methods such as laser and waterjet cutting have become standard, designers are integrating sheet metal tabs and slots directly into flat patterns to eliminate alignment issues and accelerate assembly. These interlocking features act as built-in locators, reducing reliance on jigs while improving weld accuracy and repeatability. This ultimately results […]
