Reverse engineering is also called back engineering because it involves working backward through the original design process.

The challenge is to gain a working knowledge of the original design by disassembling the product piece-by-piece or layer-by-layer because of limited knowledge about the engineering methods that went into creating the product.

In some cases, the only way to obtain the design of an original product is through reverse engineering. The original 2D drawings are no longer available for some older products that have not been manufactured for 20 years or more.

As some companies may no longer be in business, there will be no way to contact the original manufacturer, and reverse engineering comes to the rescue.

An organization will acquire an example of the product and take it apart to examine its internal mechanisms for reverse engineering. This way, engineers can unveil information about the original design and construction of the product.

When reverse engineering a mechanical product, engineers will start by analyzing;

• the dimensions and attributes of the product,
• whether it is an aircraft, ship, vehicle, computer, or
• piece of industrial machinery.

Engineers make measurements of the widths, lengths, and heights of key components in the product during this analysis because these dimensions will also reveal the product’s performance.

Reverse engineering gives you a virtual copy of the original designer’s blueprint. If you can obtain a working model of an old product, you can easily trace the steps of its design to use those insights and construct a new model, repair a part or improve future products.

Today engineers use 3D scanning technologies to gain accurate readings of the product’s specs and have this information in their databases. 3D scanning technologies include coordinate measuring machines (CMM), industrial computed tomography (CT) scanners, laser scanners, and structured light digitizers.

The reverse engineering approach is commonly used in legacy parts replacement, service or repair of the product’s parts, failure analysis, and problem-solving. After all the applicable information has been gathered, it can be used to create computer-aided design (CAD) drawings for analysis and development.

The core application for additive manufacturing technology within the BMW Group is still prototyping. Dominik was very eager to demonstrate how this implementation is still an ongoing journey during a tour of the Additive Manufacturing Center in Munich. Dominik was particularly proud of a process that saved a dashboard from recycling to put on display inside the AMC. This SLS printed dashboard is both spongy and stiff in the appropriate places but appears just like any other dashboard. This research within BMW Group series production led to the development of a printing technique that replicated the feel of foams and today the BMW group uses this research for every dashboard prototype.

Since the birth of metal 3D printing, many manufacturers have been working on the potential of series production but only a few manufacturers have succeeded with GE’s LEAP fuel nozzle being at the top. Maximilian Meixlsperger and his team at BMW came up with the first cost-effective series production of metal additively manufactured components in the commercial automotive industry. This is not an impeller for a one-of-a-kind race car or a reverse-engineered handle for a classic car.

“Normally underneath a part like this you’d have support, but we optimized it to a point where we no longer needed support structures, the part has two little feet that are the only connection to the base plate. Using this method we were also able to stack them into each other and take the build from 51 to 238 parts per platform,” said Maximilian Meixlsperger.

They made a 10 times stiffer part than the plastic injection moulded counterpart and the metal part 44% lighter at the same time as developing some novel printing techniques and building orientations for cost efficiency.

“Our new facility will be a major milestone in additive manufacturing at the BMW Group. The team there will evaluate new and existing technologies in both plastics and metals printing and develop them to series maturity. Our goal is to provide the optimum technology and process chain, be it for individual components, small production runs or even large-scale manufacturing.” said the head of the BMW Group’s Additive Manufacturing Center and the future campus director, Dr Jens Ertel.

Complex Geometries

Complexity does not mean more difficulties in the process of 3D printing. Complex geometries act as a solution for detailed and complex angles that require execution and precise measurements. In addition to it, 3D printing completes the task at a lower cost when compared with the traditional style of manufacturing.

Mass Customization

In contrast with the tooling limitations, companies can now economically produce thousands of customized parts on a daily basis. By developing a process, which integrates customer data into the physical parts, consumers can have access to affordable custom-fit products. Mass customization is the way to develop a solution that saves time, money, and material. As an example, custom-fit printed earbuds are designed by a company using Fused Deposition Modeling of ABS plastic within less than 48 hours.

3D Printing – Integrated Assembly

One promising area of 3D printing is integrated assemblies. It reduces the print time of the objects by simply integrating an assembly plan into the 3D model before printing. For example, a bunch of architecture students successfully manufactured 3D-printed flexible textile structures with FDM and SLS technologies. Designed to have both flexibility and rigidity, 3D printing is bringing new surprises to the fashion and textile industry due to its integrated assemblies.

Engineering Re-Design

With regard to Engineering Redesign, 3D printing allows the designer the freedom of recreating the product without any restrictions on part standardization, assembly, or traditionally restricted geometries. The approach produces organic structures that resemble plants, bones, or shapes that are expensive or impossible to manufacture with any other means.

As technology grows and matures, it reveals exciting innovations in 3D printing on a daily basis. We hope that the four areas give a better idea of the designing and manufacturing advantages of 3D printing.
