Integral Guidelines for Easy 3D Printing

Why 3D Printing? Additive manufacturing, often known as 3D printing is a process which is used to manufacture parts by the way of binding material layer by layer. Unlike subtractive manufacturing this technology is based on adding material layer by layer. Widely used across variegated industries like aerospace, defense, automotive, consumer products, medical and the […]

Plastic Material Selection – It’s A Jungle Out There!

Part 1 Understanding Plastic Materials David Wright in his book “Failure of Plastics and Rubber Products” divides the failures of plastic into categories and percentages as illustrated in Figure 1. Figure 1 –  Human Causes of Plastics Failures [1] As we see, almost half of the failures is contributed by poor understanding and selection of […]

DESIGN FOR MANUFACTURIBITY: GETTING MORE WITH LESS

The conceptualization of every product plays an integral role in its manufacturing. Before its eminence dawned on the industry, manufacturing was fundamentally driven by ‘if it’s designed, then it’s machined’. What followed next was often dreaded by both designers and manufacturers-a difficult (often failed) attempt to manufacture a product to meet unrealistic design expectations which […]

Ribs and Undercuts

Case in point The line of Liberty Ships from the era of World War II have often made up for an interesting case study for ship builders worldwide. As history has it, it took the loss of both stock and life to put design into perspective. An immediate inspection surmised cold cracking and hydrogen induced […]

Solving Design Issues Before They Happen

A design engineer’s role in designing a product has undergone a lot of change in this decade or so. Earlier, a designer’s responsibility was limited to only the functional requirements of the product but now they have a greater role to play in success of the product delivered by the organization. Designers have to design […]

Design for Standardization

Ever-increasing demand for new products from customers is forcing OEMs to launch innovative products at record speeds. Launching a new product could mean either starting from scratch and designing something revolutionary or putting existing pieces together and creating something evolutionary. Revolutionary products form part of a company’s long term vision while evolutionary products comprise of […]

5 Design Rules for Problem Free Injection Molded Plastic Parts

In the last couple of decades, use of lightweight alternatives such as plastics and composites has dramatically increased, with its applications well entrenched in automotive, aerospace, consumer electronics industry. Today’s car for example, has more than 150 kilograms of plastics on board in the form of seats, dashboards, bumpers, and engine components. Boeing 787 on […]

A Comprehensive Design Review Process – From ID Concept to Mass Production (Part I)

Most will agree that the process of mechanical design review that exists in organizations today is far from being fully efficient. The lack of a formal set of specific requirements at each stage of design often results in time consuming and chaotic reviews, which in turn leads to fewer actionable suggestions to be incorporated by […]
