Different industries use rapid prototyping manufacturing for product development. We rely on prototypes to minimize the chances of poor product development since faulty products can be fatal and risky to utilize.
Goto thingyfy to know more.
Therefore, these prototypes are crucial for these products’ baseline checking, quality control, and quality assurance.
For this reason, prototype development is essential for the majority of industries. We need to learn about prototype development in different aspects so that it will give us a better understanding of the significance of prototypes for various sectors.
We need to start with conceptualization, ideation, and design regarding prototype development. These steps are necessary for prototypes to be made. This step gives us a baseline idea about making these prototypes. What should they look like? What should be their features? How big should they be? For what industries would they be useful? All these factors and many more are catered to with this first step. For this reason, we use advanced designing tools like CAD to design versatile prototypes without any trouble. Such tools are readily available and speed up the process of seamless prototype development as well.
As we already know, materials are a lifeblood for CNC machined parts. We need appropriate materials to develop these parts. Due to this reason, material selection for CNC prototypes is crucial as well. These materials give us a basic idea regarding their influence on the CNC machining process during prototype development. For instance, if we use an unknown material for the first time, we can use it on our prototypes before applying it to the workpiece. We can easily find out how suitable the material is through prototyping. This will save us time, effort, and investment.
Traditional prototyping was utterly time-consuming. Also, there was a massive margin of human error due to outdated prototyping techniques. Today, we rely on the following rapid prototyping techniques that provide us with positive and desired results in industrial-grade prototyping. A quick breakdown of these techniques is below:
It is a highly reliable technique when we need to make quick and precise intricate prototypes. It uses a layer-by-layer approach, and therefore, we use it to speed up the prototyping process. Besides this, there is no need to use advanced tools for 3D printing. Due to this reason, we consider a comparatively affordable technique for complex prototyping.
CNC machining can use different materials, from metals to non-metals. It develops complex prototype geometries. We generally use CNC machining for accurate results in industries like aerospace, military, and medical/healthcare. This technique is familiar; therefore, we can easily find many CNC machining experts. This means there is no need to struggle to find the workforce and materials needed to perform CNC machining.
We can also use this method for quick prototyping. We keep the molten materials in different molds for a while. After some time, we remove these molds to use them. These molds are our prototypes, and we can use them for various types of testing before proceeding further. The injection molding technique is an affordable and valuable method for flawless, industrial-grade prototyping used by many industries.
This is the second last step of industrial-grade prototyping. The prototype testing and interaction means in-depth testing and checking for the faults in these prototypes. These prototypes undergo stringent quality control and quality assurance tests that make them safe and secure for utilization. We cannot approve any prototype for further processing without performing these tests. Due to this reason, there are strict prototype testing methods available that analyze these prototypes from all angles, and only after the approval can these prototypes be used for further operations.
This is another crucial step of the prototyping process. We need to document the entire process and write down these prototypes’ challenges, progress, pros, and cons. The documents should also mention the whole functioning of these prototypes. Documenting the prototyping process clarifies each prototype so it can be later replicated or reused. Also, documentation serves as proof that a credible authority has developed these prototypes for private processing only.
When it comes to prototyping, we should not forget about cost analysis. Well, the prototyping cost depends on different factors. If we use an expensive method, it will increase the cost. Also, if rare and costly materials are used for prototyping, the manufacturer has to adjust their budget according to these materials. Due to this reason, cost analysis and scaling are crucial factors to consider for a successful prototyping process.
The last step of prototyping involves these prototypes’ last-minute quality and appearance checks. Also, these prototypes are shipped and dispatched if they need to be sent to a client. Other than this, these prototypes are also polished and refined if needed.
Below are some major reasons for relying on prototypes. Regardless of the industry, we should consider these reasons and adapt to prototyping as soon as possible.
Prototypes empower us to use the best possible designs for our CNC machined parts. We can approve and reject these prototype designs based on quality, details, requirements, and functions. Therefore, prototypes omit the risk of poor and wrong design for CNC machined parts that cannot be undone later.
We can repeatedly test these prototypes if we want. This mostly happens when we are prototyping complex parts and geometries. It is not possible with CNC machining since repeated testing can damage these parts. Due to this reason, we can test these prototypes and improve their quality if we have to.
Using prototyping, we can easily leverage effective communication between designers and developers. The teams can work more harmoniously, making seamless collaborations possible. Teams can discuss these prototypes and share their ideas.
We can gather user feedback by using these prototypes. If they use this feedback, manufacturers can have a clear idea of their users’ sentiments and thoughts.

There are no such risks of wastage, which saves manufacturers money. The reason is that if there is a fault in a prototype, it can be easily solved. This is not possible with CNC machining parts. All the machined parts are rejected and discarded if they have any flaws or problems, which leads to the wastage of materials and investment. But with prototypes, we can easily prevent this.
There are rapid prototyping technologies available that save us time. Therefore, there are higher chances of faster time-to-market. The companies don’t have to struggle to meet the volatile market demands since they can produce the prototypes rapidly without unprecedented delays.
Prototypes improve and fasten manufacturing. The producers can easily meet the needs of their clients. Also, they can produce CNC machined parts by only replicating the corresponding approved prototypes. This will allow them to provide their clients with satisfactory results overall.
The best part about prototyping is that manufacturers have greater investment opportunities and can attract more investors when needed. This comes in handy when a budding CNC manufacturer is emerging in the market.
There are some reliable rapid prototyping techniques with corresponding applications that you should know:
Applications: CNC machining can quickly develop complex parts for industries like aerospace and military.

While the need to iterate on products swiftly remained, it wasn’t until certain technologies reached a maturation point that true rapid prototyping in the automotive industry could be achieved.
Additive manufacturing, also known as 3D printing, has been around since the s. Now, after decades of evolution, this crucial technology has reached an inflection point, becoming exceedingly relevant in various fields of engineering. More specifically, by allowing manufacturers to produce lower cost, higher quality prototypes, 3D printing technology has ushered in the next generation of rapid automotive prototyping, dramatically altering the entire design and production process in the automotive industry.
Historically, the solutions available to this industry have come from traditional methods. Prototypes for the automotive industry were often painstakingly hand-crafted from materials such as wood, clay, foam, and metal. Companies would be forced to wait for certain critical components of their prototype, significantly impacting their ability to test the product and enter into production.
The shift toward automation did open up new opportunities, yet they fell short of their potential. For instance, computer-aided CNC milling could be faster, but the high operating cost and wastefulness of materials meant it could be prohibitively expensive, not to mention the geometrical limitations of certain fabrication methods. The time spent and money wasted along the way contribute to astronomical delays and budget constraints, thereby preventing manufacturers from exploring a wider range of design options.
Thus, the paradox. To truly create groundbreaking product designs, one needs to be able to cast a wide net and experiment. Yet, without rapid automotive prototyping to quickly prove out (or disprove) product design concepts, you are limited by time and budget. Designers simply can’t waste their resources on out-of-the-box ideas for fear of falling too far behind a rigid go-to-market timeline.
Rapid automotive prototyping enables car designers and engineers to save time and resources from step one of their process. If you’re unfamiliar with the process, it is rather simple to explain. Eschewing the old practice of blueprints on paper, digital models are employed using advanced CAD software which are sent directly to a 3D printer. The printer takes these digital plans and begins dispensing fine layers of material.
2D-layer after 2D-layer, the printer applies gel according to the geometric plan, and these layers add up vertically, eventually resulting in a single 3D solid part (which is why the academic term for 3D printing is additive manufacturing: because it’s adding layers upon layers) The materials used in these 3D printers allow engineers to design components of varying rigidity, density, weight, resistance to heat and certain chemicals, etc.
There are different types of printers to fit varying needs, each with different technological approaches on how to deliver the best results. Yet, regardless of the type of printer, the technology as a whole has always been limited by two main factors: size and speed. Most 3D printers are only capable of producing smaller parts, since full-size parts are simply too big – and even if they were able to fit the size, the slow rate of printing such large pieces would render nearly any project too expensive.
This is problematic, both in terms of additional time required as well as the structural integrity required in prototypes for industries such as automotive. Even if a printer was able to print a larger-than-usual piece, they work incredibly slowly, often requiring several days for a single part to be created. These limitations caused both serious delays and increased costs in the development stage, denying automakers the flexibility to rapidly develop and test new prototypes in a cost-effective manner.
Thankfully for automakers, next generation additive manufacturing technology is already here. Printers such as the Massivit Pro 3D have changed the rules of the game, by enabling the creation of larger and more complete products than ever before, in just a fraction of the time. This development has set the stage for the kind of rapid automotive prototyping for which the industry has long pined for.
Massivit’s vastly improved rapid prototyping technology is capable of producing complete parts up to 6 feet / 1.8 meters in length, which is a significant increase from market norms. This allows automakers to produce life-sized components such as bumpers and body panels for their mockups, something that could previously be done only with miniature models, or by a heavily-manual fabrication process with much higher labor costs and time requirements. Additionally, Massivit has dramatically increased the speed of printing so that these larger components can now be delivered in a matter of mere hours.
A perfect example of this happened at the SEMA convention in Las Vegas, where we teamed up with STREETFIGHTER LA to launch the STREETHUNTER DESIGNS Supra MK5 Wide Body Kit. This brand new kit included all the body panels and the dynamic rear wing for a fully customized vehicle.
Typically the production of these parts would take weeks, and they would then need to then be transported to the show. Printing them locally with the Massivit Pro 3D printer took just 64 hours for over 16 parts. This includes printing the front lip and rear spoiler as single parts, each nearly 5 feet long.
Whether it is a functional customized kit such as the one pictured above, or prototypes to be tested before entering the production line, the applications of large volume 3D printing with a Massivit printer are endless.
