Why Tighter Tolerances Aren’t Always Better Precision is important in manufacturing, but more precision is not automatically better. One of the most common forms of over-engineering is applying unnecessarily tight tolerances to dimensions that ... Aug 12, 2026
The “Golden Sample” Trap: When Prototype Success Doesn’t Scale A prototype that passes every validation test does not automatically guarantee production success. One of the most common sourcing mistakes occurs when suppliers present “golden samples” that have bee... Jul 28, 2026
From Pass/Fail to Process Capability: Why Cpk Tells the Real Story Traditional pass/fail inspection answers a simple question: did this individual part meet specification? While that information is necessary, it provides little insight into whether the manufacturing ... Jul 20, 2026
Tolerance Stacking: When Small Variations Become a Big Assembly Problem Tolerance stacking is one of the most underestimated risks in mechanical design. A single ±0.1 mm tolerance may appear insignificant when reviewing an individual component, but assemblies rarely depen... Jul 14, 2026
The T0 Triage: Evaluating the First Shots Without Overreacting to Cosmetic Flaws The first shots from a new production tool, commonly known as T0 samples, are intended to validate the process, not to represent final production quality. Yet many projects lose valuable time because ... Jul 7, 2026
Myth: Simulation Is an “Extra” Cost. Fact: Simulation Is an Insurance Policy Against a $50,000 “Oops” in the Tool Shop. Engineering simulation is sometimes viewed as an optional expense that can be skipped to accelerate development or reduce upfront costs. In reality, simulation is one of the least expensive ways to pr... Jul 1, 2026
The Silent Killer: How a 0.5 mm Tolerance Creep in a Sub-Component Led to a 15% Field Failure Rate Most field failures are not caused by catastrophic design errors, they result from small dimensional variations that accumulate throughout an assembly. In one manufacturing program, engineers traced a... Jul 1, 2026
Build Report Basics: What We Share After a Successful Run A successful metal additive manufacturing build is more than a finished part, it is a complete record of the process that created it. Every production run generates valuable information, from machine ... Jun 23, 2026
Forgetting Material Certs and Heat-Treat Callouts in the PO A purchase order is more than a request to manufacture a part, it is a critical communication document that defines exactly what must be delivered. One of the most common sourcing mistakes is failing ... Jun 16, 2026
Single Build vs. Staggered Builds: Lead-Time Tradeoffs One of the most important production planning decisions in additive manufacturing is determining whether to place all parts into a single build or distribute them across multiple staggered builds. Whi... Jun 15, 2026
Omitting Leak or Pressure Specs on Fluid Parts Fluid-handling components are often designed around geometry, flow paths, and connection interfaces, but one critical detail is frequently overlooked during development: defining leak-rate and pressur... Jun 14, 2026
GD&T for AM-to-CNC Handoffs: Datum Strategy That Works Transitioning a part from additive manufacturing to CNC machining is not as simple as moving it from one machine to another. Metal AM parts naturally experience distortion, shrinkage, and residual str... May 27, 2026
