Additive manufacturing or 3D printing has impacted the industrial development of products and modeling in many fields. More commonly called additive manufacturing, 3D printing involves creating an object through a physical process that takes the form of a 3D model. The following are the advantages offered by this advanced technology over the conventional prototyping techniques when it comes to early stage model and prototype development:

Speed 

In the case of using 3D printing in the prototyping process, one of the greatest strengths is the ability to quickly print out different versions of the prototypes. In case of using traditional approaches like CNC machining or injection molding, companies are able to get new versions of a prototype only in several days or even weeks, when it is evaluated. But there is always a possibility to make small objects using many types of desktop 3D printers in only a few hours. This is a faster cycle that allows designers or engineers to try out slight adjustments on the design, correct it if the need arises, and reprint. Compared to other manufacturing techniques, 3D printing has the advantage of being able to create tangible models based on digital data within a fairly short time, which makes it possible to truly test multiple iterations quickly. The ability to switch from the computer model to the testable prototype in an extremely short timespan allows for more refined designs from the early development stages.

Even in industrial 3D printing for larger and complex parts, this process may still last several days. However, the use of industrial 3D printing is advantageous by reducing the time taken to source metal or plastic parts from other manufacturers by significantly high percentages. It is also worth noting that in 3D printing, there is no requirement for a high MOQ or expensive tooling as is often the case in manufacturing. It allows for the consideration of other design ideas right from the start of the developmental process. The implication of this is that firms can be in a position to deliver better products to the market more quickly than their counterparts who are stuck with the use of traditional subtractive manufacturing techniques.

Cost Efficiency 

Consequently, the 3DP has a higher cost efficiency for prototyping in comparison with traditional processes besides the accelerated speed. What we know about additive manufacturing is that it eliminates the use of molds or tooling, and as such, it is suitable for use in cases where the production of prototypes is limited. Most conventional operation processes do not have numerous advantages of mass production or if they have, they are insignificant when it comes to small or single production runs. On the other hand, the cost of 3D printing is relatively fixed irrespective of the number of parts to be produced and hence relatively cheaper than investing in a complete tooling setup for prototyping.

Any modifications or design alterations go on to show another advantage of using 3D printing in that it saves on cost. Compared with other approaches, a direct modification of the digital CAD file and printing again is relatively cheap since one does not need to create new molds or machining fixtures to incorporate changes. Due to the relative small quantity of individual parts which can be produced by 3DP, and the fact that these can even be changed at a very fast pace, the overall contender for the cost leader is 3DP for the iterative nature of prototyping where requirements may still change. Waste is also reduced since in the process of using the additive manufacturing system only the required amount of material needed is used. In contrast, in CNC milling up to 90% of the material may be cut and/or carved away and thrown away.

One of the advantages of use of 3D printing is that since then costs are reduced, multiple of the same design can be printed at the same time depending on the tests. Since companies can obtain definite optimized printer capacity with one printer, they can increase capacity through more 3D printer hardware. Most of the other investments are in design files and at basic material levels, meaning that there is little need for more investments. Similarly, additive manufacturing is also more suitable in terms of testing as flexibility and easy setup for mass variation are obvious added values when testing is done on a greater scale until enough feedback is gathered.

Complex Geometry & Customization

3D printing provides more than simple tool for modeling and prototyping to allow various new product designs with enhanced characteristics and customization which are not possible to introduce using conventional manufacturing technologies. Aesthetics is enabled by the freedom of design for additive manufacturing that allows the production of intricate internal structures and lattices that are almost impossible to achieve by conventional methods. The new type of structure characterised by hollow patterns of certain interconnection degree, network structure, and lightweight contour opens new opportunities in the formation of the first experimental and prototype models and testing of functions. Geometry like the one embedded in parts such as aircraft or automotive elements may create enhanced performance characteristics such as stiffness, weight, and strength. The capabilities of testing around such types of advance designs enable the engineering difficulties to be gotten to the bottom of during the earlier stages of prototyping.

It is notable that due to the high complexity of some of the part, there may be necessary additional finishing work depending on the selected print resolution. That being the case, fine tuning the design is the least of the issues when compared to the general potential for probing functional demands. Mechanical engineers have the opportunity to 3D print working engines or their parts with connected and mobile parts integrated into one build. This eliminates the need to source several components or even custom tools so one can build fully integrated working models. Bettiable prototyping in a manner that mimics final products assists in identifying flaws and vulnerabilities at concept stages of product development.

It is also easier to create a custom or personal one in a successful manner when using the 3D print capabilities. When it comes to adapting individual parts to fit certain environments or to address specific user needs, the custom approach gives one the ability to test the aspect in a more real-life setting. Additive manufacturing effectively creates one-off design for application that best fit the specific requirements and limitations in a way that would prove to be time-consuming and expensive for small batch production by more conventional manufacturing technologies. The uniqueness of the 3D printing concept can help companies that create prototypes of new products for immediate assessment of the most suitable customized applications and specialized use.

Ease of Design Modification

The use of 3D printing in production offers the benefits of improved speed and productivity during the development and actual use of a part. Modifications do not involve changing anything physically; one only has to edit the 3D file and then print it. As in additive manufacturing, the process goes directly in to the CAD model, changes can be made directly from the screen to the physical model easily without inconvenience or difficulty. It means that designers and engineers can introduce correction for enhancement without waiting for a long time like other ordinary machined or injection molded prototypes that require outsourcing. There is no limitation on design change when it comes to 3D printing; thus, the product teams do not have to wait for changes to be done by others or organizations since they can do everything on their own and at a very high speed depending on the development objectives.

Simplified modification enhances the application of 3D printing for the iteration of designs in a product development process in line with the findings of assessments. When more versions are being run, there are more adjustments that can be made to boost competency. Design modification and optimization is easy hence enabling this testing to tinker process, which is basic to the first-stage prototyping use. It allows for quick updates to CAD and quick reprints which in turn give better prospects for developing detailed function analyses that are crucial to advancing design and engineering.

Conclusion

Innovative product design can be achieved through creating and evaluating new product models by applying quick successive prototyping methods, a tool that offers competitive advantage to organizations that desire to be leaders in the innovation race. Using assembled prototypes and disassembling them and assessing their effectiveness, possible research can be focused on important performance characteristics and unorthodox ideas that cannot be implemented after high-cost manufacturing tools have been developed. 3D printing provides an easy-to-implement technology, which brings the fail-fast mindset required at the idea inception stage. The possibility to make prototypes available and cheap as well as to allow for more complex and unique design of the object under construction creates new ways for refining next generation products. Additive manufacturing and 3D printing are still moving forward and are constantly pushing the boundaries of building and testing more prototypes, which uncovers new approaches to invention for organizations seeking to discover opportunities early in the product development process.
