(and disadvantages)

TL;DR : The main advantages of 3D printing are: reducing costs, less waste, reduce time, get an competitive advantage, reduce errors, confidentiality, production on demand. Disadvantages …

As far as recent inventions go, the advantages of 3D printing make it one of the most promising technologies. The additive technology is one of the biggest advantages of 3D printing, it opens a whole new way in which product are created and it offers a lot of advantages compared to the traditional manufacturing methods.

There are many different types of 3D printing technologies available, but the benefits of 3D printing discussed here are applicable to the whole industry. Through fast design, high levels of accuracy and the ability to make informed decisions, the following 3D printing advantages make this technology a real prospect for businesses but also highlight its importance in future production techniques.


Our 7 advantages of 3D printing:

  1. Cost reduction
  2. Less waste
  3. Reduce production time
  4. An enhanced competitive advantage
  5. Reduce errors
  6. Confidentiality
  7. Production on demand

1. Cost reduction

Less machine, material and labor costs

For any business, costs reduction is important and one of the advantages of 3D printing is that it will help to bring those costs down. Manufacturing costs are split into three different categories known as: machine operation costs, labor costs and material costs.

Machine costs

Machine operation costs play a very small part in the overall cost of the manufacturing process. While the energy required to create parts in an industrial environment can be high, the ability to develop and create complex parts and products in one step creates an increased level of efficiency and saves on time. Therefore, the cost of running the machines is offset by the savings made during the manufacturing process.

Labor costs

One of the good points of 3D printing is the fact that labor costs are kept low. Unlike traditional manufacturing where different people may be required to operate a number of different machines or a production line is required to put the product together. Each 3D printer will require an operator to start the machine and start the automated process of creating the uploaded design. Therefore, the labor costs are significantly lower as traditional manufacturing.

Material costs

The range of 3d printer filaments used for 3D printing is growing and this makes it possible for the price to decrease over the last years. But, in the same way as the machine operation costs, in comparison to traditional methods, the overall cost are a lot lower.

Less travel costs

One of the biggest advantages of 3D printing is that it can also help to reduce the amount of distance that a product will travel. As 3D printers can create a product from start to finish, it enables designers to design the product in one country, email it to another country in preparation for production. There is no requirement to create prototypes that have to be moved around from factory to factory in order to complete the process. This makes 3D printing an industry that can be created around the world without leaving a footprint. Therefore, there is a reduction in shipping, air travel and road travel.

Next to the design and production of prototypes, it’s also possible for spare parts to be produced on site and that can help to significantly reduce the carbon footprint.

2. Less waste, more sustainable

The traditional manufacturing process is mostly a subtractive process, where the raw material gets wasted and reused over and over again, this results in high costs and waste. An advantage of 3D printing is the unique way it builds the product with very little waste, this is called additive manufacturing.  While the more traditional methods will have waste that can be re-used or recycled it still takes time and effort to determine just how and when the waste will be used. This even makes large volume 3D printer a very sustainable option.

Thermoplastic materials, for instance, can be melted, cured (cooled down such that they become solid), melted again, cured again, and so forth. Therefore manufacturing ‘waste’ can be reused (thus preventing it from becoming “waste” in the first place).

3. Reduce time

We live in a fast paced world where everything is required quickly and so, this is where 3D printing can really make a difference. One of the big advantages of 3D printing is that parts and products can be manufactured a lot quicker than they can using traditional methods. Complex designs can be created as a CAD model and then transformed into a reality in just a few hours. This delivers design ideas in a way that enables them to be verified quickly and designed in a short space of time. This is so advantageous over traditional methods as they can take weeks or months to go from the design stage to prototype stage and right through to the production process.

4. Provides an enhanced competitive advantage

The ability to reduce the time of the prototyping phase, businesses can deliver better, improved and enhanced products in a shorter space of time. Giving a competitive advantage over the competition. But it also makes it possible to develop products early, creating prototypes more frequently until the product is perfected and ready for production creating a highly effective product launch.

And the competitive advantage of 3D printing is taken to the next level with our 3D printers. Having the ability to create a life-size prototype makes it possible for designers to think differently about the products that they design.

In business, it is important to show customers or investors the products that you are going to offer. But, to produce a product that they may not even like can prove costly and so, it is often left to the imagination as products have to be described. This increases the risk of information being lost somewhere during communication and that can cause severe problems at some point. One of the advantages of 3D printing is that it makes it possible to create a product quickly that people can physically hold, removing any concerns or miscommunication. While it may be a prototype and open to alterations, it at least provides a small insight into what the product will look like, offering a truer representation than that of a description.

Test the Market

Understanding whether a product will be a success requires a lot of research, especially where traditional manufacturing methods are concerned. However, creating a prototype through 3D printing will make it possible for businesses to obtain feedback from potential buyers and investors in a way that could never be achieved before. The product can be customized and altered right up to the very last minute which is something that traditional manufacturing methods do not offer. This means that 3D printing offers a unique and valuable way of identifying whether a product has the potential to make it to market and be successful at the same time.

5. Reduce errors

When it comes to designing parts and products, designers have to consider efficiency. Many parts and products require a high number of steps using traditional methods of manufacturing in order to be produced. Therefore every step could result in an error, with the risk of starting over again, leading to problems with the overall manufacturing process. A single step manufacture process is more beneficial.

There are many industries that have a long and drawn out production process. Where some of the steps are to create a CAD model, then developing a prototype that may require adjustments before it is finally sent for final production. This is a process that takes a lot of time and none of the steps can be skipped because they all play a part in the production process. However, one of the advantages of 3D printing is that it creates the product in one single step, with no interaction from operators during this process. Just finalize the design and upload it to the printer. This removes dependence on a number of manufacturing processes and enhances the control over the final product.

During the traditional manufacturing process, faulty prototypes cost time and money. With every faulty prototype, you need to go back to the drawing board, with no guarantee it would be right the second time around. Even small adjustments have a significant financial and time impact on the whole process. This is where 3D printing can remove risk because designs can be verified through creating a production-ready prototype before going ahead with the final creation. This helps to increase confidence in the design before investments and further money is paid to take it to the next level of production for the mass market.

6. Confidentiality

Continuous prototyping and manufacturing in-house with a 3D printer ensures that designs never leave the company premises, safeguarding your intellectual property. No third parties can ever claim your innovations for themselves. Every innovative design is kept in-house, so there is no need to worry about confidentiality any longer.

7. Production on demand

The ability to have full freedom in the design is one huge advantage of 3D printing. It also enables designers to customize designs. As 3D printing is perfect for one-off productions and building single parts in one process, it means that the ability to customize is there to take advantage of. Therefore, many industries such as medical and dental have embraced 3D printing and design because of the ability to create customized implants and aids. In fact, sporting gear can be created to fit athletes and so, custom, person specific parts can be created in a way that has never been seen before.

Traditional methods relied on molds and cutting and this makes customizing a very time-consuming process. In contrast to this, the customization of products created through 3D printing can have enhanced structural integrity improved, complex changes made and parts altered to fit certain requirements. Customization in this way, gives 3D printing an endless amount of possibilities.


For any business, their customers are key to their success and so, customer satisfaction becomes an important part of their strategy. Through keeping ahead of the competition and providing customers with what they want, industrial 3D printers have changed the way in which businesses deliver exactly what their customers want. The expectations of customers has changed because they want their items quickly and efficiently.

It is clear to see that there is a wide and varied array of 3D printing advantages. Many different industries are starting to introduce 3D printing into their processes in an attempt to benefit from using the technology in the various different ways. It is a technology that has grown considerably in recent years and it will continue to grow as it continues to fine-tune what it has to offer. When all of the 3D printing advantages are considered, it is obvious that this will soon become a technology that will overtake traditional methods, it is just a matter of time.

It is the ability to print complex shapes and interlocking parts without the need for any form of assembly that makes 3D printing so unique. It is possible to create small, intricate shapes at a very small cost and in a short space of time. The ability to develop and produce different shaped objects without the need for specific tooling offers businesses a higher level of flexibility when it comes to production and it helps to reduce costs. The strong point about 3D printing is that it improve innovation and is perfect for on-demand customisation needs. It gives businesses the power to design and create products in a way that has never been seen before. It is a process that enables the imagination to be free because there are almost no boundaries. It can bring back to life old designs for a number of industries where parts have become obsolete.

Despite 3D printing being a relatively new technology, it has grown in popularity to the point where it is now accessible due to a reduction in costs. The number of printers that are being sold is growing at an incredible rate and what was once a niche technology to only those who could afford and use it, it is not reaching far and wide to many different industries. This ease of access has changed the manufacturing process in a way that has not been seen for decades.


Disadvantages of 3D printing:

  1. Initial costs of printer
  2. Post processing
  3. Printing time
  4. Special skill required for 3D models
  5. Manufacturing Job Losses


1. Initial costs of printer

You need to buy the 3D printer, and even tough the return on investment is quick and high, the initial investment has to be done.

2. Post processing

A 3D printed object, in most cases, needs some post processing to be used.

3. Printing time

When it comes to manufacturing many objects, the 3D printers are slow in comparison to other manufacturing technologies. Next to the mass production, an other disadvantges is the long printing times for one off prints. Depending on printer size and quality, it can take several hours to days to print, but when the printer makes a fault when it’s almost finished printing, you have to start over again. However, by making sure the 3D model and the print file are designed and sliced well and the printer is setup correctly you can almost guarantee the print will come out perfect.

4. Special skill required for 3D models

Once you have obtained a printer you have to learn how to make and alter 3D models. 3D modeling is a skill that requires a lot of time and effort to fully master, it’s a process of trial and error. But once you know how to use the software you will be able to print whatever comes to mind.

5. Manufacturing Job Losses

As we mentioned in the advantages of 3D printing, the technology can make product designs and prototypes in a matter of hours as it uses only one single step. It eliminates a lot of stages that are used in traditional manufacturing. As a result it doesn’t require a lot of labor cost. As such, adopting 3D printing may decrease manufacturing jobs. For countries that rely on a large number of low skill jobs, the decline in manufacturing jobs could dramatically affect the economy. However, it’s likely that robotics will have a much larger impact here.

What are the Advantages and Disadvantages of 3D Printing?

3D printing, also known as additive manufacturing, is becoming popular with manufacturers. The demand is growing due to some of the revolutionary benefits that it can provide. Like almost all technologies it has its own drawbacks that need considering.

This page aims to help with the selection process. We will cover each of the advantages and disadvantages of 3D printing.

This production process offers a range of advantages compared to traditional manufacturing methods. These advantages include those related to design, time and cost, amongst others.

1. Flexible Design

3D printing allows for the design and print of more complex designs than traditional manufacturing processes. More traditional processes have design restrictions which no longer apply with the use of 3D printing.

2. Rapid Prototyping

3D printing can manufacture parts within hours, which speeds up the prototyping process. This allows for each stage to complete faster. When compared to machining prototypes, 3D printing is inexpensive and quicker at creating parts as the part can be finished in hours, allowing for each design modification to be completed at a much more efficient rate.

3. Print on Demand

Print on demand is another advantage as it doesn’t need a lot of space to stock inventory, unlike traditional manufacturing processes. This saves space and costs as there is no need to print in bulk unless required.

The 3D design files are all stored in a virtual library as they are printed using a 3D model as either a CAD or STL file, this means they can be located and printed when needed. Edits to designs can be made at very low costs by editing individual files without wastage of out of date inventory and investing in tools.

4. Strong and Lightweight Parts

The main 3D printing material used is plastic, although some metals can also be used for 3D printing. However, plastics offer advantages as they are lighter than their metal equivalents. This is particularly important in industries such as automotive and aerospace where light-weighting is an issue and can deliver greater fuel efficiency.

Also, parts can be created from tailored materials to provide specific properties such as heat resistance, higher strength or water repellency.

5. Fast Design and Production

Depending on a part’s design and complexity, 3D printing can print objects within hours, which is much faster than moulded or machined parts. It is not only the manufacture of the part that can offer time savings through 3D printing but also the design process can be very quick by creating STL or CAD files ready to be printed.

6. Minimising Waste

The production of parts only requires the materials needed for the part itself, with little or no wastage as compared to alternative methods which are cut from large chunks of non-recyclable materials. Not only does the process save on resources but it also reduces the cost of the materials being used.

7. Cost Effective

As a single step manufacturing process, 3D printing saves time and therefore costs associated with using different machines for manufacture. 3D printers can also be set up and left to get on with the job, meaning that there is no need for operators to be present the entire time. As mentioned above, this manufacturing process can also reduce costs on materials as it only uses the amount of material required for the part itself, with little or no wastage. While 3D printing equipment can be expensive to buy, you can even avoid this cost by outsourcing your project to a 3D printing service company.

8. Ease of Access

3D printers are becoming more and more accessible with more local service providers offering outsourcing services for manufacturing work. This saves time and doesn’t require expensive transport costs compared to more traditional manufacturing processes produced abroad in countries such as China.

9. Environmentally Friendly

As this technology reduces the amount of material wastage used this process is inherently environmentally friendly. However, the environmental benefits are extended when you consider factors such as improved fuel efficiency from using lightweight 3D printed parts.

10. Advanced Healthcare

3D printing is being used in the medical sector to help save lives by printing organs for the human body such as livers, kidneys and hearts. Further advances and uses are being developed in the healthcare sector providing some of the biggest advances from using the technology.

Like with almost any other process there are also drawbacks of 3D printing technology which should be considered before opting to use this process.

1. Limited Materials

While 3D Printing can create items in a selection of plastics and metals the available selection of raw materials is not exhaustive. This is due to the fact that not all metals or plastics can be temperature controlled enough to allow 3D printing. In addition, many of these printable materials cannot be recycled and very few are food safe.

2. Restricted Build Size

3D printers currently have small print chambers which restrict the size of parts that can be printed. Anything bigger will need to be printed in separate parts and joined together after production. This can increase costs and time for larger parts due to the printer needing to print more parts before manual labour is used to join the parts together.

3. Post Processing

Although large parts require post-processing, as mentioned above, most 3D printed parts need some form of cleaning up to remove support material from the build and to smooth the surface to achieve the required finish. Post processing methods used include waterjetting, sanding, a chemical soak and rinse, air or heat drying, assembly and others. The amount of post processing required depends on factors including the size of the part being produced, the intended application and the type of 3D printing technology used for production. So, while 3D printing allows for the fast production of parts, the speed of manufacture can be slowed by post processing.

4. Large Volumes

3D printing is a static cost unlike more conventional techniques like injection moulding, where large volumes may be more cost effective to produce. While the initial investment for 3D printing may be lower than other manufacturing methods, once scaled up to produce large volumes for mass production, the cost per unit does not reduce as it would with injection moulding.

5. Part Structure

With 3D printing (also known as Additive Manufacturing) parts are produced layer-by-layer. Although these layers adhere together it also means that they can delaminate under certain stresses or orientations. This problem is more significant when producing items using fused deposition modelling (FDM), while polyjet and multijet parts also tend to be more brittle. In certain cases it may be better to use injection moulding as it creates homogenous parts that will not separate and break.

6. Reduction in Manufacturing Jobs

Another of the disadvantages of 3D technology is the potential reduction in human labour, since most of the production is automated and done by printers. However, many third world countries rely on low skill jobs to keep their economies running, and this technology could put these manufacturing jobs at risk by cutting out the need for production abroad.

7. Design Inaccuracies

Another potential problem with 3D printing is directly related to the type of machine or process used, with some printers having lower tolerances, meaning that final parts may differ from the original design. This can be fixed in post processing, but it must be considered that this will further increase the time and cost of production. 

8. Copyright Issues

As 3D printing is becoming more popular and accessible there is a greater possibility for people to create fake and counterfeit products and it will almost be impossible to tell the difference. This has evident issues around copyright as well as for quality control.

10 Benefits of a 3D Printer: Save Time and Money

More recently, 3D printing has been viewed as something completely new. The technology was underdeveloped, the hardware was too expensive for widespread use. But only a few years have passed, and the situation has changed radically. Not only did more and more 3D printers begin to appear in stores, but also some enthusiasts began to assemble this equipment themselves.



Although large-scale projects with thousands of 3D printed parts are not cheap, they are still much more profitable than other technologies. Many manufacturers use 3D printing for small runs or for prototyping. Plastic can also be used for injection molding, but casting small batches can require expensive equipment. But even in this case, manufacturers can produce cast 3D parts several times cheaper than using aluminum.

2. Faster production cycle

Compared to traditional production methods, the entire process can take weeks or days, and most products are printed in hours. Some manufacturers have even begun to make parts to order, which has also allowed them to optimize their warehouse capacity and resource management scheme, making them more flexible. With this new approach, the manufacturer does not need to store every single part or component, they can simply be printed as needed and immediately put into action.

5. Greater customization

3D printed products are also highly customizable. Parts can be printed not only with light plastic, some next-generation models may also have a metal coating. As a result, objects are not only aesthetic, but also functional. In addition, they can acquire thermal and chemical resistance. The existing metallization method can also be used for plastic.

6. Customer Accessibility

If some craftsmen set up small mechanical workshops, for example, in garages, then most of us cannot afford such a luxury. 3D printing allows you to bring a significant part of the manufacturing process directly into the home, made possible by the availability of user-grade 3D technology. While it turns out to be quite expensive for one-off projects, the price of 3D printers and consumables is dropping rapidly.

7. High complexity

In most cases, when it comes to complex parts and elements, the manufacturing process imposes certain limitations. Techniques used in casting and finishing objects may not be subtle enough for sophisticated design details. 3D manufacturing processes make it possible to realize almost any design solution, regardless of its complexity, and in a reasonable time. This not only eliminates the extra assembly steps required by traditional methods, but also provides more freedom to create future-proof designs.

Less risk

While there are inherent risks associated with these new technologies, in terms of day-to-day business, 3D printing risks are significantly lower than with traditional manufacturing methods. Not only is 3D printing much cheaper when it comes to testing a new design or product, the printed prototypes themselves can stir up investor and customer interest and get them to decide whether to proceed with mass production of a product, whether it is worth the time and effort required.

9. Variety of materials

The materials used in today's 3D printers are much more diverse than most raw materials in traditional production methods. 3D printing also provides the ability to mix different substances, a luxury that is not always available with conventional methods. Although many 3D printer manufacturers offer their own, very limited set of sources, 3D printers can work not only with original materials, allowing you to simulate ceramics, metal, glass and more.

The manufacturer not only needs to clearly understand what the customer wants, the manufacturer must also be able to explain what he himself can. Drawings, diagrams, diagrams are all good, of course, but there is nothing better than a real prototype that you can hold, look at and study. The fact that the materials are inexpensive, coupled with the short prototyping time on today's 3D printers, helps a lot during the prototyping phase, keeping all stakeholders connected.


Despite a relatively slow start, the concept of 3D printing is finally gaining momentum and popularity among manufacturers and customers. We already see a lot of benefits of 3D printing, including shorter production cycles, more complex designs and improved quality, and the peak of the popularity and functionality of this technology is yet to come.

Benefits of 3D printing

The article reveals the main advantages of 3D printing in comparison with traditional production technologies.


During 3D printing, objects are created in layers. This approach has many advantages over traditional production methods. There are various techniques for 3D printing, but the benefits discussed in this article apply to the entire industry as a whole.

It is unlikely that 3D printing will replace modern production processes, but there are areas in which 3D printers allow you to quickly and accurately create the necessary product. Understanding the benefits of 3D printing enables engineers to make the best decision when choosing a production technology, which reduces the cost of products and / or improves their quality.

Speed ​​

One of the main advantages of 3D printing is the speed of part production. Complex models can be downloaded directly from the CAD environment and printed in just a few hours.

In the past, making a prototype could take days or even weeks. Now this entire technological process can be safely replaced by the work of one engineer who will provide a sample in a few hours. Yes, industrial 3D printers last a long time, but if your samples are small, you will save a lot of time.

The illustration below shows a fastener made of nylon.

Production in one setup

One of the main tasks of an engineer is to optimize production as much as possible. For the manufacture of most parts, it is necessary to apply several different technologies and sequential processing steps, which directly affect the quality and speed of production of parts.

Let's look at an example of making a simple wall hook. As with 3D printing, the manufacturing process starts with a CAD model. Once the design is approved, the manufacturing process begins. The desired piece of steel is cut off. After that, it is given the necessary shape. Probably, after shaping, it is necessary to measure the resulting part. The surface is processed and brought to the desired size. Holes for wall mounting are drilled, chamfers and fillets are formed.

If you are using a 3D printer, all of these operations can come down to one. Once the CAD model is ready, you can upload it to the 3D printer and have the finished product in a few hours.

The ability to produce parts in one set-up makes life much easier for the engineer, who is no longer dependent on separate equipment for turning, milling, pokarski, etc.

The image below shows the 3D printing process (red) compared to the traditional process (black).


The cost of producing a part can be divided into 3 parts: the cost of equipment, material and the cost of specialists.

Cost of equipment operation: Most desktop 3D printers use the same amount of electricity as a laptop or desktop computer. More powerful, industrial printers use more energy, but the ability to produce products in one setup still makes them more efficient and less resource intensive. By the way, the cost of the operation of technological equipment is the smallest in comparison with other items.

Cost of materials: The cost of materials for 3D printing varies for different printing technologies. Desktop FDM printers use materials that cost about $25 per kg, while SLA prints cost about $150 per liter. The presence of different materials complicates the process of comparison with classical production technologies. For example, nylon mixes for SLS cost about $70 per kg, while comparable nylon pellets used in injection molding can be purchased for $2 - $5 per kg. The cost of material is the main component of 3D printing production.

Cost of specialists: One of the main advantages of 3D printing is the cost of specialists. If you do not take into account post-processing, you need a person who will press one button. The further process is fully automated. Compared to traditional production, which requires highly skilled, trained operators, the cost of specialists for 3D printing is almost zero.

As mentioned above, 3D printing is much more profitable for small volumes. Basically, it is used to create prototypes of future products. Traditional production methods come into play when large parts are produced or a large batch of parts is launched.

Risk minimization

Even small changes in a part can lead to a significant change in the cost of its production. For example, the presence of grooves in the part forces the use of milling. This may require new equipment or a machine operator. So being able to test and refine a design on a prototype ensures that risk is minimized before a large batch is launched.

Complicated shapes

In a classic production process, there are always some limitations that must be taken into account. For example, you don't have the necessary equipment to form precise spherical surfaces. This is a problem because it is not cheap. 3D printing removes these limitations as the part is built up layer by layer. As a rule, in 3D printing, the only limitation is the minimum size. It is difficult to print small elements. But this problem rarely occurs, so the advantage is still obvious - you can easily realize products of the most complex geometry.

Miscellaneous applications

Since we are not limited by the configuration of the part, the main concept of 3D printing is to produce one product for one task. This idea has taken root especially well in medicine. Now, 3D printers are used to print custom-made prostheses, implants, and dental fillings. Manufactures fashion accessories and home furnishings. The image below shows headphones made with a 3D printer.


3D printing technology is not new. She is already about 30 years old. But the main demand for it appeared in the last 5 years. This led to the emergence of a large number of 3D printers and lower their prices. In 2015, over 278,000 3D printers were sold worldwide for less than $5,000. What was a curiosity a few years ago is now part of most businesses. And the open-source movement opened the way for desktop 3D printers to ordinary homes. For example, at the time of 2017, you can buy a Chinese 3D printer for $150-$200.

The chart below shows sales of 3D printers under $5,000 from 2017 to 2015. Note that for the past five years, the number of sales has doubled per year.

Zero Waste

Classical processing methods require the production of a part from a blank that is larger than the final product.
