Hi readers! I hope you all are doing well and learning and exploring new things. We live in an era where technology is growing faster every day. Prototyping is the rough and simple model of the product that innovators want to introduce into the market. They perform tests, and if the results are unsatisfactory they fix the problem and reprocess them faster to beat the competition in the market. Rapid prototyping becomes crucial for the foundation of the development of modern products. Rapid prototyping sped up the path from the initial steps to the formation of the product. Rapid prototyping is highly demanded as compared to traditional methods because it is cost-effective, saves time, consumes fewer resources, and produces several products rapidly and efficiently.
In the early days, the process of manufacturing products took time, was costly, and used high resources. Little modification in the product was not easy because it consumed more resources and was costly. Rapid prototyping solved all these issues efficiently when it evolved in the early 20th century. It has become advanced in computer-aided designs (CAD) and 3D printing. It allows companies to bring new products into the market rapidly. It has diverse applications in industry, automation, health care, electronics, aeroscopes, and software development.

Choosing between 3D printing and CNC machining can be pivotal for manufacturers, designers, and engineers. Each method has distinct advantages, depending on factors like production volume, material requirements, and the complexity of the design. 3D printing offers unparalleled flexibility. It allows for rapid prototyping and intricate geometries that are difficult to achieve with traditional methods.
On the other hand, custom CNC machining is known for its precision and ability to work with a wide range of materials, making it ideal for producing high-quality parts with tight tolerances. Understanding these differences is crucial for selecting the right technique for your project, whether looking to innovate quickly or produce durable, high-quality components.
This article will look at the key aspects of 3D printing and CNC machining. It will help you determine which method best suits your needs.
3D printing, or additive manufacturing, is a cutting-edge process to create three-dimensional objects from a digital model. This technique involves building the object layer by layer, which sets it apart from traditional subtractive manufacturing methods that remove material from a larger block. The digital model, typically created using Computer-Aided Design (CAD) software, serves as a blueprint for the object, guiding the printer through each layer's construction.
CNC machining, short for Computer Numerical Control machining, is a versatile manufacturing process involving automated machine tool control using computer programs. This subtractive manufacturing technique removes material from a solid block or workpiece to create a highly precise and accurate finished part.
Below are some of the key differences between 3D printing and CNC machining:
3D printing offers nearly limitless design flexibility, allowing for the creation of complex geometries and intricate details that would be difficult or impossible to achieve with traditional manufacturing methods. This freedom is due to the addictive nature of the process, which builds parts layer by layer without the need for specific tooling or support for internal features. As a result, designers can focus on optimizing the functionality and aesthetics of the part without being constrained by the manufacturing process itself.
On the other hand, CNC machining is limited by certain design constraints inherent to the subtractive process. These constraints include tool access, tool path, and the need to avoid undercuts and internal geometries that are difficult to reach with cutting tools. Additionally, CNC machining requires careful planning of tool paths. It may also involve multiple setups and repositioning of the workpiece to achieve the desired shape. This method can restrict the complexity of parts that can be efficiently produced.
The precision of 3D printing varies depending on the specific technology used. Generally, the resolution can range from 0.016 mm to over 1 mm, with typical consumer-grade 3D printers achieving around 0.2 mm precision. While this is sufficient for many applications, achieving high precision consistently across different geometries and materials can be challenging.
CNC machining produces parts with high precision and tight tolerances. It can achieve precision levels as fine as 0.005 mm by employing slow feeds, new cutters, and shallow cuts. This makes CNC machining ideal for applications with critical dimensional accuracy and surface finish, such as aerospace and medical device manufacturing.
Operating a 3D printer generally requires less specialized skill compared to CNC machining. The process involves preparing a digital file, selecting orientation, and adding necessary support. Once the setup is complete, the printer performs the build with minimal human intervention, making it accessible to users with basic technical knowledge.
CNC machining demands a higher level of operator skill due to the complexity of setting up the machine, programming tool paths, and selecting appropriate cutting tools. Operators need to have a deep understanding of the machining process, material properties, and the capabilities of the equipment to consistently produce high-quality parts. This expertise is critical for achieving the desired precision and surface finish.
3D printing typically has a low setup time, but the actual build time can be lengthy. It often takes several hours or even days to complete, depending on the size and complexity of the part. This makes it suitable for prototyping and low-volume production, where quick iteration and design flexibility are prioritized.
CNC machining can have high setup and programming times, particularly for complex parts. However, once the setup is complete, the cutting stages are very fast, allowing for rapid part production. This makes CNC machining well-suited for high-volume production runs where speed and efficiency are essential.
The surface finish of 3D-printed parts can vary widely based on the technology used. Common issues include graininess, rough textures, and visible layer lines. Post-processing methods such as sanding, polishing, and media blasting can improve the finish. However, achieving a smooth, high-quality surface can be challenging without additional work.
CNC machining can produce excellent surface-quality parts, particularly when using longer cut times and finer cutting tools. The process can achieve a highly uniform and precise finish, making it ideal for applications where aesthetic and functional surface properties are important. Various post-processing techniques, such as anodizing and powder coating, can further enhance the surface finish of machined parts.
The strength of 3D-printed parts is often lower than that of their machined counterparts. Depending on the printing process and material, the strength can range from 10% to 20% of the native material's properties. This is due to the layer-by-layer construction, which can introduce weaknesses and inconsistencies in the final part.
CNC machining produces parts with the full strength of the native material, as the process involves removing material from a solid block. It results in parts with superior mechanical properties and durability, making CNC machining the preferred choice for applications where strength and reliability are critical.
Choosing between 3D printing and CNC machining is influenced by your specific needs. 3D printing is ideal for rapid prototyping, complex geometries, and low-volume production with diverse material options like plastics and metals. It offers customization and reduced waste but may require post-processing for a smooth finish.
CNC machining excels in high precision, consistency, and the ability to work with a wide range of materials, including metals and composites. It's best for producing parts with tight tolerances and in larger volumes. Ultimately, the choice depends on the project's complexity, material requirements, and production scale.
Although 3D printing feels like a relatively new development, there are lots of promising projects underway. A scheme to build 46 eco-homes has been approved in the UK’s first 3D printed development , for example, and the same is happening in Australia to provide housing for remote indigenous communities in rural areas .
But how can 3D printing be applied in business? Here’s a breakdown on how it can be used and the opportunities it creates.
3D printing refers to technology that can form materials using computer designs. The earliest signs of 3D printing came about in 1981. Dr. Hideo Kodama created a rapid prototyping machine that built solid parts using a resin and a layer-by-layer system.
Using a bottom-up technique, the material is layered until a tangible item is created. We are still in very early days when it comes to 3D printing, but engineers are optimistic about how it can be applied on a large scale across industries. There’s great potential for using 3D printing in manufacturing and home building.
3D printing begins with a design stage. This is the 3D modelling stage where you can uncover the best path to follow to get the most out of the design, such as the materials used. You will also be able to use this information to determine the cost and speed of your project, adjusting where necessary.
3D printing equipment is powered by a system of control cables such as those from RS to facilitate autonomous 3D printing applications. Data connections are also used to transmit the design to printing equipment.
3D printing is commonly used for prototyping ahead of launching major manufacturing projects. It allows product designers to get a life-size glimpse at the proposed product, enabling them to identify any faults or improvements before going ahead with more expensive resources and materials. While 3D printing can be done to a large scale, it can be done to a much smaller scale too to create smaller, cost-effective prototype models.
The attention that is given to the design process and modelling stage means companies can analyse the production method used to create the desired output. Sometimes there will be limitations such as the fact that 3D printing can only work when adding layers on top of one another, which means features like overhangs can’t be catered towards in a simple manner. Regardless, 3D printing can still cater to things that traditional manufacturing can’t.
3D printing can be used to minimise demand on time and manpower. It can be used to tackle more intricate tasks at a larger scale. Aerospace was one of the first industries to utilise this, as well as biomedical and mechanical engineering. In some cases, conventional manufacturing simply can’t replicate the detail at such a large scale.

There is no escaping from the fact that cutting-edge technological developments and evolving market innovations are pushing 3D printing into the mainstream. According to experts, the 3D printing market is expected to become a multi-trillion-dollar industry. It will rise from a $ 5 billion market to $55.8 billion by 2027. This is enough reason why many industries have started to embrace it.
The 3D printing market has gained popularity due to the maturing business environment. And now that all sorts of businesses have picked pace after COVID-19, the 3D market has become quite a rage.
And the market continues to experience massive success among home users and hobbyists. The number of 3D printers has doubled in the last few years. However, the combined value of the overall industrial/commercial sector is larger.
Secondly, due to the high cost of industrial and commercial 3D printing hardware, the raw material costs are higher too. Thus, entrepreneurs have to step back when making important decisions.
Here are the most common types of 3D printing raw materials that are used all over:
Polylactic Acid
Acrylonitrile Butadiene Styrene
Polyethylene Terephthalate Glycol Modified
For your information, the chemical and plastics industry makes these materials in large numbers. They are relatively inexpensive and readily available. Plus, they’re easy to handle and processed in fused filament fabrication. Currently, the most readily available raw materials are bronze powders and aluminum. Plus, there are selected grades of stainless steel and managing steel. Not to forget, a limited number of titanium alloys too. The private industry has already spent a lot of money on its research and development.
Remember that leadership in the global 3D printing industry will continue to boom in Western Europe and North America. And with a lot of young people enrolling in AutoCAD course , the demand is expected to boom only. And the widespread adoption of the 3D printing processes will also cause a magnetic transformation in supplier-customer relationships.
Most of these innovations are centered around evolutionary pressures from the latest technology. Plus, the increase in production speed, reliability, efficiency and system costs are to be noted too. Secondly, the staggering increase in product quality is yet another reason for this technology to know no bounds.
With the advancement in technology and the complexity of 3D printing, value chains have evolved as an organic consequence. Currently, the industrial and commercial 3D printing installations work as stand-alone units too. They are not intimately integrated into the manufacturing workflow and environment. For most companies, however, 3D printing is still relatively new.
They are taking time to get accustomed to this technology's chances. And companies with deep experience in using 3D printing in design and workflow. Developing a value chain in a business is very important. Thanks to 3D printing, it has enabled businesses to foster strong relationships with their customers.
However, today we will focus on the additive manufacturing technique and what you should look for during your search. Numerous businesses embrace the technology by delegating tasks to professional 3D printing services.
In the globally competitive environment, adding a supply partner to the company's value chain is the way to go because the technology is capital-intensive to implement. To help more businesses adopt the technology, we've created a simple guide to help them select the best 3D printing solutions partners.
Working with a 3D printing provider gives you direct exposure to a broad scope of 3D printing technologies. A 3D printing service can handle a wide range of industrial projects thanks to its extensive capabilities. As a result, one of the essential criteria in selecting the best 3D printing service for you is the wide variety of current technologies.
The service provider has significant expert knowledge in all technologies due to their broader technology scope. As a result, they can recommend and help consumers with the technology that will help them get the most out of their initiatives.
Choosing a 3D printing service isn't complete without considering the materials. Material considerations play an essential role in decision-making. Not all materials can be utilized successfully with all techniques.
Only some technologies can efficiently use solid materials. As a result, consider material availability when selecting a 3D printing service. The 3D printing service you hire should be experienced in printing with the required material.
The importance of design in 3D printing is frequently overlooked. While any design can be 3D printed, some can't be done well. Methods for additive manufacturing precepts should be used when designing for 3D printing.
A service agency must be aware of the difference and, as a result, strongly recommend or endorse design changes that are compatible with 3D printing. This compatibility can help customers save time, money, and materials while improving part effectiveness, longevity, and trustworthiness. As a result, choose a 3D printing service that specializes in design.
While contacting a 3D printing service with a wider variety of technologies is usually a good idea, it is not always the best option. Numerous service providers specialize in a specific area of expertise. This is commonly seen in medical and healthcare settings.
Medical implementations of 3D printing, as well as some aerospace implementations, must meet specific rules and regs. Service bureaus with FDA or ISO-approved amenities, technologies, materials, and procedures should be chosen for particular applications.
If you're working on a one-off 3D printing project, the 3D printing service you choose won't have an impact on your long-term work, product, or public image.
However, if you want to integrate 3D printing or outsource long-term work, finding the right 3D printing provider should be a priority.
Nowadays, more businesses across many industrial sectors adopt 3D printing as a viable alternative to subtractive manufacturing (acquiring machined parts online) and injection molding. We'll look at the benefits of 3D printing and how you can use this production method to benefit your company. Is it worthwhile to use 3D printing for your project?
One of the best aspects of 3d printing is the reduced labor costs. Operating costs heavily influence the quantity of money spent on building a structure. Whenever it comes to traditional manufacturing, production costs are incredibly high, and skilled machine operators are required. In 3D printers, however, all that is needed is for an operator to press a button, and the printer's automated process will take care of the rest. Furthermore, 3D printing is comparable to both small-scale and large-scale manufacturing.
Due to the speed and lower expenses of 3D printing, item life cycles are decreased. Organizations can improve and upgrade an item permitting them to convey better things in a more limited time.
3D printing permits the actual show of another item to clients and financial backers instead of passing it on to their minds, accordingly lessening the gamble of data being misconstrued or lost during communication.
It also enables low-cost test marketing, allowing prospective clients to provide feedback on a physical item without the risk of high upfront prototyping costs.
Traditional production techniques can lead to shoddy designs and, as a result, shoddy prototypes. Consider baking a cake where all of the ingredients are blended and mixed before being baked. If the ingredients were not extensively combined, the cake would have air bubbles or fail to bake thoroughly. The same thing can happen when using subtractive or injection techniques; quality isn't always guaranteed.
Because of the nature of 3D printing, it is possible to assemble a part or product step by step, resulting in improved design and higher quality parts/products.
Traditional manufacturing techniques are efficient at making dozens and dozens of identical items, but the models are devoid of life and repetitive.
While 3D printing allows designers to create unique models with limitless personalization, it also makes it easy to include unique features that customers demand. Meaning you can get precisely what you want after handing over your 3d printing quote to a form well-versed in this sector.
The majority of additive manufacturing's constraints relate to how to generate a print quickly enough to eliminate the need for support. As a result, developers are free to create intricate geometries and concepts.
3D printing is a cutting-edge technology that is preferable, cost-effective, speedier, more viable, adaptable, and environmentally friendly than previous generations. We currently reside in a fast-paced universe where everything needs to be done quickly, and 3D printing technology can help us turn our ideas to life; this is a massive advantage in the printing world.
Several industries use 3D Printers in printing various outputs they need; The industries include footwear, architecture, jewelry, construction and engineering, education, automotive, medical and dental industries, aerospace, and consumer products.
According to Woodford (2021), inkjet printers usually spray liquid ink, while a laser printer applies solid powder in its production. Well, a 3D printer does not use any of the two. Instead, it uses plastic in physical object modeling.
According to Formlabs (2021), the world's first 3D Printer is stereolithography, invented in the 1980s. Most professionals are still using the SLA technologies in production. The Stereolithography 3D Printer applies the photopolymerization process in its functioning; The process includes using a laser to cure liquid resin into hard plastics.
The Printer is popular because of its production ability of watertight, isotropic, and high-accuracy prototypes or parts. The parts or prototypes have advanced materials range with good quality features and smooth surface finishing. The Stereolithography resin offers vast mechanical, thermal, and optical elements to match the industrial, standard, and engineering thermoplastics properties.
Several industries use stereolithography—for example, dental, engineering, education, modeling, and manufacturing industries.
Stereolithography parts constitute a smooth surface finishing, fewer visible lines, and sharp edges.
Application of stereolithographyThe LCD 3D Printer uses UV LCDs arrays as its light source. The LCD panels produce light that directly shines onto the building area in a parallel fashion. Pixel distortion is not a problem in LCD 3D Printer because its light is not expanded. The printing quality is dependant on the LCD 3D Printer's density; increasing the pixels produces better quality (Leo, 2019).
The LCD 3D Printer has a faster building speed when compared to SLA 3D Printer; it prints parts faster.
A selective laser sintering (SLS) 3D Printers sinters small polymer powder particles to form a solid structure using a high-power laser. The SLS has unfused powder whose function supports the part when the Printer is printing and removes the need for a dedicated support structure. Hence, the SLS is suitable for complex geometries, including the negative and interior features, thin walls, and undercuts (Formlabs, 2021). The SLS 3D Printer produces parts with superb mechanical characteristics. Furthermore, it has strength that resembles the injection-molded parts' strength.

Applications of an SLS 3D printerFused Deposition Modelling (FDM) also refers to the Fused Filament Fabrication (FFF). Consumers popularly use FDM 3D Printer. The printer functions by releasing thermoplastic filaments like the Polylactic Acid (PLA) and Acrylonitrile Butadiene Styrene (ABS) via a heated nozzle, building a platform through heating the material to melt and applying the plastic on successive layers until completion of the part (Formlabs, 2021).
The FDM 3D printer is the most favorable for simple, low-cost Prototyping and basic proof-of-concept models. Compared to SLS and SLA 3D Printers, FDM 3D Printer has the lowest accuracy and resolution; hence, it is advisable not to use the FDM 3D printers in printing designs that are complex or have intricate features. Mechanical and chemical polishing processes are used in obtaining higher-quality surface finishes. An industrial mitigates challenging issues through soluble support and allows a wide variety of engineering thermoplastics, increasing production costs.
FDM parts show visible lines responsible for creating inaccuracies when handling complex features.
Application of FDM 3D printerA resin refers to a highly viscous substance of synthetic or plant origin typically converted into polymers; generally, the resin is a combination of organic compounds (Liqcreate, 2021). Transparent resin is mainly used in 3D printing in a transparent material. Transparent resin is suitable for 3D printing because of its water-resistant property. Also, the transparent resin is an ideal choice for that requires high quality, smooth finish, and fine surface.
According to Liqcreate (2021), several types of resin are used in 3D Printers basing on their functions or purpose. They include the general-purpose, premium, medical, castable, engineering, and creative purpose resin.
