Custom End Effectors and EOAT: Design and Manufacturing Guide

In robotic automation, the end effector, or End of Arm Tooling (EOAT), is where the digital instructions of the controller meet the physical realities of the workpiece. These terms refer to the specialized hardware mounted to a robot flange that interacts with parts, tools, or the surrounding cell environment. The terms are interchangeable in practice […]

Turret Punching, Laser Cutting, and Combination Machines: A Design and Process Guide

Laser cutting is a very familiar process for most engineers designing sheet metal parts. Despite being an older technology, CNC turret punching is often overlooked at the design stage, even though it remains widely used in production.  Process selection is critical because it can drive feature size, edge appearance, tooling cost, and the types of […]

The Ultimate Guide to Injection Molding Tolerances

Injection molding tolerances are acceptable variations in size for part features and overall dimensions. They are expressed as plus or minus (±) values in millimeters or inches and vary by the type of material that’s used and the overall size of the part.  Part designers add tolerances to 2D drawing files to tell an injection […]

Design for Testability (DFT): Building Products That Are Easier to Test and Validate

What Is Design for Testability (DFT)? Design for Testability is the practice of deliberately engineering a product so that its functions, performance, and integrity can be efficiently verified at every stage: prototype validation, end-of-line production testing, incoming inspection, field service, and depot-level repair. When testability is baked in from the start, you catch failures earlier, […]

Teardown: The Breville Bambino Plus

High-Pressure Engineering in a Small Form Factor The Breville Bambino Plus compresses key espresso machine architectures—thermal management, pump-driven pressure control, and automated milk texturing—into a compact footprint. At the $500 price point, it occupies the middle ground between entry-level (home) and professional-grade (fancy bistro). After unboxing, we did what any sane engineering team would do: […]

FictivMade: Mold Trials & Revisions for Production-Ready Injection Molds

In earlier chapters of FictivMade, I walked through the detailed design process, DFM analysis, and how to kick off the tooling order. While placing the order is a big milestone, there is still more work to be done before the finish line. Now comes the stage of the multi-tool phone stand project where the injection […]

The Best 3D Printers in 2025 – A Complete Guide for Every Need

So you’ve got a great idea for a new product, have a design ready, and can even picture it on store shelves. Now what? Many product designers look to 3D printing to test their ideas and get a sample in their hands relatively quickly and inexpensively. As 3D printing expands into professional and industrial use, […]
