25 (Unexpected) 3D Printing Use Cases

For years, hype around 3D printing captured audiences in the mainstream press. With visions of a future including a 3D printer in every home, these predictions were light on details and ultimately most did not come to fruition. However, the possibilities of 3D printing were undeniable, despite the youth of the technology and the relatively low number of use cases that were viable in the past.

The initial hype masked legitimate and growing business applications for 3D printing. With a proliferation of high-performance desktop and benchtop machines being introduced into the market, we are now seeing a broader variety of businesses expanding their product offerings and delivering better results to customers.

What can you do with a 3D printer? Read on to discover 25 (often unexpected) 3D printing use cases that show the broad scope of possible applications for the technology.

A new industry report that compares how recent and early adopters are using 3D printing for their business, and explores future trends of the technology.

3D printing can add enormous value to supply chains, unlocking a broad spectrum of production applications. The technology is growing more workable and affordable, with companies able to bring additive manufacturing in-house to support processes on the factory floor. New, resilient 3D printing materials are opening opportunities for the production of high precision, functional 3D prints that can stand in for final parts, offering customization opportunities that help designers radically push the boundaries of high-performance cars. Industrial design studio Vital Auto has put all of this technology to work creating high-fidelity prototypes and concept cars, rapidly working through iterations using a variety of advanced tools, including a large fleet of in-house 3D printers.

“We've used 3D printing from day one. We wanted to introduce it to our manufacturing processes, not only to reduce costs, but to give the customer more diversity with their designs and their ideas,” said Design Engineer Anthony Barnicott.

The automotive industry has seen the value additive manufacturing can add to multiple touch points in the creation of automobiles. This means going well beyond rapid prototyping to include:

Creating custom, complex, and high-performance parts
Producing tooling and manufacturing aids
Manufacturing replacement parts and spare parts on demand
Cutting costs and lead times by up to 90% compared to outsourcing

Recent advancements in 3D printing technology have started to fundamentally change the audio industry, meaning that digital printing of custom fit ear devices for the audiology, noise protection, and consumer audiology industries has never been so affordable. In recent years, 3D printing manufacturers have brought skin-safe biocompatible materials to market, allowing for in-house production of ear models and headphone tips.

Custom fit offers a unique individual listening experience built around the earphone fitting exactly in the customers ear. This gives a secure fit that removes any possibility of earphones falling out of the ear, in addition to improved comfort and noise isolation.

“We are very excited about the concept of custom fit to deliver a custom experience to further enhance immersive listening. Formlabs shares Sennheiser’s drive for innovation – and improving the customer experience through this prototype is a testament to that mindset.”
Sennheiser Director AMBEO Immersive Audio, Veronique Larcher

The challenges that come with customized manufacturing can be overcome through the combination of Formlabs' disruptive printing technology and mobile scanning coupled with machine learning. This means customers can have easy access to custom fit earphones, with lead times reduced from four days to next day delivery or even same day.

restor3D tools being printed, along side their final form.

Ten years ago, few people were talking about the huge impact 3D printing would have on the medical industry, from helping create advanced medical devices to patient-specific surgical guides. One company no one saw coming was restor3d, who leverages 3D printing capabilities to drastically improve surgical care by printing procedure-specific polymer instrumentation tailored to cervical spine implants.

With a fleet of over 25 Formlabs 3D printers in its production line, restor3D is already printing the next generation of surgical tools. For surgeons using these tools, this procedure-specific, single packed sterile instrumentation system results in:

Replacement of large, expensive surgical trays.
Ability to iterate designs and quickly introduce new tools or features based on surgeon preferences.
Dramatic reduction of supply chain and sterilization costs for hospitals.

As much as 3D printing technology has developed in the past few years, there are even more high-impact, use cases currently in development. 3D printed organs is one of them.

Being able to easily create new organs has for decades been a dream for scientists working in regenerative medicine. While it remains in its early stages, the use of the 3D workflow to produce organic tissue eligible for transplant is bearing early fruit.

Dr. Sam Pashneh-Tala from the University of Sheffield is leading the way. His research uses high-precision desktop stereolithography (SLA) 3D printing to enable the production of tissue-engineered blood vessels with a variety of geometries. This will allow for patient-specific vascular graft designs, improved surgical options, and provides a unique testing platform for new vascular medical devices for those suffering from cardiovascular disease—which is currently the number one cause of death worldwide.

“My differentiator is that I’m able to create blood vessels with geometries that are more closely matched to those found in the body. This offers the potential for improved surgical options and even patient-matched blood vessel designs. Without access to high-precision, affordable 3D printing, creating these shapes would not be possible, ” said Dr. Pashneh-Tal.

The reconstruction of the three cities in the two different time periods consisted of over 650 segments, which were printed using Formlabs White Resin, each measuring 12x12cm.

As an industry already based on geometric design, prototyping, and modeling, architecture stands to gain enormously from advances in 3D printing technology.

On top of saving time during model production, the 3D printed models allow architects to anticipate the effects of certain design features with much greater certainty, e.g., by seeing a model produced with a fuller complement of materials, an architect can measure aspects such a light flow through the structure with higher precision.

But 3D printing’s use case goes beyond a single model: some firms are recreating entire towns. Institute of Architecture at the Hochschule Mainz - University of Applied Sciences. The result is an extraordinary exhibition that showcases six large-scale models of the cities, in the years 800 and 1250 AD. The models consist of over 650 parts, all of which were created using SLA 3D printing technology.

The sport-footwear industry has long relied on technology to optimize the performance of their products, and with the digital workflow they have more options than ever in customization.

Large brands like New Balance, Adidas, and Nike, having recognized the power of additive manufacture, intend to mass produce custom midsoles made from 3D printed materials. As in other industries, the digital workflow will augment traditional methods of manufacture here—critical, highly-customized components of each product will be entrusted to the 3D printing, and the rest left to traditional means.

Given the unique properties required for footwear, New Balance worked with Formlabs to create a custom printing material which could resist the daily wear and tear faced by an athletic shoe. Shoe materials experience a variety of environments, with the additional need to withstand various levels of pressure thousands of times per day. Designed to create springy, resilient lattice structures, Rebound Resin has a much higher energy return, tear strength, and elongation than any other Formlabs material. Rebound Resin is strong enough to be used in gaskets, seals, and automotive interiors, but light and flexible enough for the sole of a shoe.

“One of the things that’s really exciting for us is that it provides a very different experience for the runner.”
Katherine Petrecca, General Manager of Footwear at the Innovation Design Studio, New Balance

3D printing has already been integrated into the production of Hollywood films and is widely used for practical visual effects and costuming.

Whereas the creation of film's most fantastic creatures once required meticulous handcraft, the increased deadline pressure and time demands of modern moviemaking have made a quicker method of creating practical effects vital. Effects studios like Aaron Sims Creative now use a hybridized approach, practical effect-making enhanced by the digital workflow, to create new opportunities for collaboration and cut lead times on bringing ideas to life.

“The Demogorgon was one of the first prints that we did using our Formlabs 3D printers, and we were amazed. Before that, we had always outsourced printing. So to be able to grow it in-house, and see a design that we helped create from the very beginning printed right in front of us, was kind of an amazing thing. It was like going back to the days when we used to sculpt with clay,” said Aaron Sims.

3D printing's artistic potential is not limited to physical artwork. It also has the power to bring entirely new dimensions to forms like dance and music. Given the design freedom inherent in 3D printing, even the most complex or unique instruments can be modified or created from scratch, at a fraction of the price of traditionally made instruments.

Having been around for centuries and barely changing, the violin’s form is recognizable to all. Violin music has evolved to such a high level that the instrument has attained an almost legendary status in our culture. But Formlabs engineer Brian Chan challenged himself to create a fully-functional acoustic violin, using a 3D printer and Formlabs White Resin.

3D scanning, CAD, and 3D printing have been used to restore the works of some of history's most famous artists, returning works by the likes of Michelangelo and da Vinci to their former glory.

Art restoration projects can be enhanced by combining 3D printing and 3D scanning, two powerful technologies that allow builders to take physical objects, turn them into three dimensional shapes, make changes or restorations, and re-print the parts.

Mattia Mercante uses 3D replication to replace lost pieces of sculptures and fine artworks at the world-renowned Opificio institute in Florence, allowing museum visitors to experience the art as the artists intended.

For one 17th-century reliquary, Mercante scanned intricate frame details from elsewhere on the piece using an HP 3D Structured Light Scanner, and then replicated the missing pieces on a Formlabs 3D printer. The prints were painted to appear identical to the original decorations. Best of all, the restoration required minimum CAD modeling, and was fast and affordable compared to hand craft.

3D printing has as much potential utility in reconstruction as it does in production. The work of a forensic artist is often made difficult by incomplete evidence. Digital technologies can be of tremendous use in legal investigations and can augment the abilities of forensic artists to reconstruct accurate models of persons of interest or victims.

The digital workflow here involves turning CT scans into 3D prints to aid in identification. For instance, when investigators find just part of a skull as evidence, a printer can model and replicate the complete sample.

Reconstructions of the appearance of crime victims have already played a key role in attaining justice, proving once again the utility of 3D printing beyond considerations of design and productive efficiency.

Just like 3D printing can be used for preoperative planning, CT scans of crime victims can help detectives get up-close to bones. Digital CT scan and X-ray data of remains can be used to produce 3D-printed replicas of various body parts. Then, the pathologist can determine the full circumstances of a crime, from the number of participants to the nature of the weapon used.

3D printing's impact is not limited to improving workflows or enabling rapid prototyping. It can also change lives directly. With 30 million people worldwide in need of artificial limbs and braces, there is hope that 3D printing can provide new solutions where cost and specification have traditionally been hurdles.

3D printing can provide an affordable alternative that, like many related advances in medicine, can provide therapy that is much more closely tailored to a patient's needs. The affordability and customizability of 3D printing techniques can profoundly alter the quality of life for the better for those suffering from injury or disability, as we saw in this story of a father and son.

We saw this type of innovation first hand with Matej’s and Mateja’s son Nik, who was suffering from cerebral palsy. Matej set out with a simple goal: to enable Nik to walk. Months of research and development followed, resulting in a custom-made, 3D printed orthosis that provides support and correction exactly where Nik needs them, which finally helped him take his first steps independently. Watch the full video above and read their story.

Beyond prosthetics which return lost function to a user’s body, it is possible to 3D print devices which are, in some ways, even better than the limbs they are replacing. With 3D printing, this is no longer a future possibility about bionetic, robo-cop like body parts, but part of the latest in cutting-edge prosthetic production. Some firms, such as Psyonic, are already delivering advanced prosthetics.

Maybe people think of 3D printing as producing smaller items which you can hold. In recent years, firms have been exploring manufacture-scale additive workflows that can produce much larger functional components. In the last few years, various initiatives have gotten underway to create houses and larger structures that are entirely the product of 3D printing, opening new frontiers in sustainable living and construction.

3D printing technique gives freedom of form to architects, even with previously less malleable building materials like concrete. More broadly speaking, it allows fully sustainable and energy-efficient homes to be built that also meet modern comfort standards. Construction by this means could be entirely waste-free, as well as less expensive and environmentally costly as traditional methods.

While you will not be moving into a 3D printed house on the near horizon, you can experience 3D printed construction projects today. The MX3D Bridge in Amsterdam is currently open to foot traffic. According to dezzen.com, the “structure used 4,500 kilograms of stainless steel, which was 3D-printed by robots in a factory over a period of six months before being craned into position over the canal this year.”

Origin Labs, within the Innovation Hub, will have a space dedicated to 3D printing for students and the broader community.

Most institutions of higher education are focused on preparing their students for the workforce of the future. The Pennsylvania State University is focused on the current workforce as well and has recently invested millions of dollars into building the Eric J. Barron Innovation Hub, which serves the public as well as the University community.

The Appalachian mountain range in western and central Pennsylvania has historically been the center of the nation’s coal mining industry, and enjoyed a solid and prosperous economy in the first half of the twentieth century because of it. As global and domestic economies shifted away from coal, the Appalachian region suffered, with a higher rate of joblessness and one of the lowest household income rates in the country, as reported by the Appalachian Regional Commission.

Over the last two decades, leadership at the local and state levels have sought to change that through investments in manufacturing, education, and technology. The Appalachian Regional Commission offers $1 million grants to “support educational opportunities and institutions, especially by connecting skill development and workforce training with local and regional business interests and opportunities.”

As additive manufacturing rapidly expands in a wide range of businesses (as seen in this blog post!), hiring managers are looking for employees trained in working in digital spaces and fluent in CAD. Universities are looking to address this market lead by creating large and well funded innovation hubs.

Besides training tomorrow’s workforce in CAD and 3D printing, universities are starting to see the benefits of deploying 3D printers across a wide range of educational disciplines.

At UMass Lowell, that meant modernizing its sculpting and 3D design courses for the 21st century. Enter Yuko Oda, who joined the university in 2017 and got started by ordering a multitude of 3D printers, including a Formlabs SLA machine.

Yuko is able to take her passion for art and technology into the classroom, currently teaching sculpture, 3D modeling and animation, and interactive media. Most students know that they’re required to understand 3D animation and 3D modeling for future careers in various fields, including sculpture design for cinema. For studio artists, 3D modeling has become an essential skill.

“Students sculpt a 3D model, import it into Zbrush, then print in various resins, including Clear Resin. The ability for Formlabs machines to show intricacies that were modified in Zbrush is unparalleled when compared to other printers in the lab.”
Yuko Oda

One of the most promising new developments in sculpture is the integration of 3D printing and Virtual Reality (VR). This is especially salient for students intimidated by 3D design. VR is rapidly reducing barriers for 3D design, allowing artists and students to create with their hands in programs such as Oculus Medium. Yuko has taught 8th graders how to create a 3D object in 30 minutes in VR, and then print the artwork on a 3D printer. Even for seasoned sculptors, VR reduces the time it takes to go from an idea to a physical object, potentially opening up new areas of experimental art.

While caretakers at ZooTampa were performing a routine check-up on a 25-year-old great hornbill, they found a lesion at the base of the bird’s casque, the yellow helmet-like growth on top of the head. Further examination determined that the bird, named Crescent, was suffering from life-threatening cancer.

The cancer, located near the bird's skull, couldn't be removed because it housed part of the bird's sinuses. The team wanted to know if they could remove the casque, and replace it with a 3D printed replica designed specifically for this bird. Patient-specific prosthetics and devices have been used before in human procedures, but never for a great hornbill. Would it be possible, and if so, which materials would be safe for the bird?

ZooTampa says the successful 3D-printed “replacement beak,” was created using BioMed White Resin. This material is an opaque white material for biocompatible applications requiring long-term skin contact or short-term mucosal contact. Special among Formlabs SLA 3D printing materials, this medical-grade material is validated for short-term tissue, bone, and dentin contact.

3D Printing and Veterinary Medicine

During the COVID-19 pandemic and following supply chain crises of 2021/22, many firms turned to 3D printing to help keep machines online and products rolling off the factory floor. The expanded use of in-house 3D printing to create end-use parts, such as replacement parts for machines, has made additive manufacturing a key tool to address supply chain problems.

Formlabs commissioned the 2022 3D Printing Applications Report to better understand what, if anything, has changed recently among 3D printing users. The report demonstrates the shift in attitudes around 3D printing from an R&D and prototyping tool to an invaluable manufacturing technology needed to meet evolving consumer preferences and overcome supply chain challenges. Whether working to ease supply chain constraints, creating limited run products, or personalizing devices, businesses have been forced to rethink how they produce goods to meet customer demand.

Building 3D printers is always an engineering challenge. Packing industrial-grade performance into an affordable, sleek desktop machine requires years of engineering and design work. This was especially true of Formlabs’ much anticipated selective laser sintering (SLS) 3D printer, the Fuse 1.

One of the tools Formlabs engineers used to prototype parts was the Fuse 1 itself. But the use of 3D printing didn’t stop at prototyping. Today, every single Fuse 1 unit shipped to customers contains multiple production parts printed directly on a Fuse 1 using Nylon 12 Powder.

Using the Fuse 1 SLS printer to prototype and create end-use parts offered three main advantages, according to Seth Berg, the engineer program manager overseeing the Fuse 1:

The design freedom to create complex parts without internal support structures.
Reducing supply chains by prototyping and creating end-use parts in-house.
Eliminating outsourcing to achieve an affordable solution for small-batch production with a proven, versatile Nylon 12 material.

To see how the team did this, and which end-use parts on the 3D printer and 3D printers, watch the video below.

In May of 2020, Forbes ran an article titled: How 3D Printing Test Swabs Will Help Fulfill America's Shortage. They noted that the 3D printing industry has come together to tackle the COVID-19 swab shortage head on, with Formlabs, HP, Origin, Carbon, Desktop Metal and more working to ramp up swab production.

The impact of the COVID-19 pandemic required a global, concerted response. Through collaborating with USF and Northwell, Formlabs enabled a solution that has been deployed worldwide. With the accessible design, affordable equipment, and validated processes, the swab design enabled over forty million COVID tests in twenty five countries. Over the last year, Formlabs 3D printers have continued being used by governments and healthcare providers to improve patient testing and care. This global solution is just one example of how the agility of 3D printing can benefit the public good.

We saw this happen dramatically in Singapore, where Eye-2-Eye Communications ramped swab production to over 30,000 swabs per day to help keep the city safe.

“It has not only been an excellent opportunity to showcase the advantages of 3D printing for rapid design and development but it has also shown Formlabs effectiveness in being able to mass produce products in very short timeframes. Also, as we see spikes in cases across the globe it is reassuring to know we can scale our production relatively easily to meet demand if required,”said Chief Executive Officer of Eye-2-Eye Communications, Miles Podmore.

One problem with creating custom aftermarket parts is these orders are typically low volume, and need to evolve in response to product updates by the original manufacturers. But with the rise of in-house 3D printing, custom manufacturing has sprouted in multiple industries.

Battle Beaver Customs is focused on delivering a premier gaming experience through custom gaming controllers. Their modifications make the controllers more responsive and more competitive, allowing players to increase their gaming potential and reach peak performance across a range of games. Rapid prototyping with the Fuse 1 SLS 3D printer allows Battle Beaver Customs to quickly change their mount and button designs. When building custom consumer products, quick turnaround times can pay dividends for businesses looking to stay ahead of their competitors. According to Head of Research and Design at Battle Beaver Customs, Michael Crunelle, the “Fuse 1 has been great for being able to make changes quickly, from concept to end-use part. Our competitors can’t keep up with us."

JetBoatPilot, a marine parts and accessories manufacturer, has built a reputation as an authority in the industry by creating aftermarket products that improve the performance and low speed handling of jet powered boats.

JetBoatPilot utilizes the Form 3 SLA and Fuse 1 selective laser sintering (SLS) 3D printers to prototype and manufacture aftermarket parts. A newly designed and now top performing product, the Lateral Thruster 2.0, was designed and manufactured on the Fuse 1. Equipped with the Fuse 1 and Nylon 12 Powder, JetBoatPilot was able to cut costs by 6x compared to their previous manufacturing methods.“I probably would have made that (aluminum version) retail price somewhere in the $400 dollar range, maybe even $600 dollar range, if I really had pushed it. I wouldn't have sold nearly as many at $600. But now I'm selling it for $199 and the customer is happy as they can be. And I'm twenty times the cost of goods,” says JetBoatPilot founder Will Owens.

With 928 stores spanning across 48 countries, Lush Cosmetics is a retailer known globally for making creative and crowd pleasing products such as Massage Bars, Body Butters, Bath Bombs and more, attributes its success to being able to respond quickly to trends and customer demand.

To bring new, industry defining, highly-detailed cosmetics to life, Lush needed to turn to 3D printing for much more than prototyping new shapes. They’ve invested in a next-generation additive manufacturing center for mold creation, tooling, and end-use parts.

The Lush Cosmetics team vacuum forms using 3D printed molds in-house.

“We use our Formlabs 3D printers for a mix of mold creation, custom tooling, and end-use parts. We’re a reactive business and having this capability in-house means we don’t need to share designs externally as we own everything in the product development process,” said Damien Carter, Innovation Lab Manager at Lush Cosmetics.

3D printing is unleashing new possibilities and business opportunities, such as mass customization. What used to be too complex, prohibitively expensive, or impractical to produce with traditional methods is available at no extra cost with digital technologies, giving full control to designers and opening the door for fully customizable consumer products to become a reality.

A good example of this is Gillette’s Razor Maker™, which gives customers the opportunity to customize the handle of their razor by picking various designs, colors, or adding custom text.

“For Gillette, piloting Razor Maker™ represents a crucial step in our customization journey where new technology and new business models must come together in order to deliver products that are as unique as our consumers,” said Donato Diez, global brand manager for Gillette and Razor Maker™

Dentistry has also been one of the most prominent drivers of 3D printing investment, desktop 3D printers are an increasingly common sight in dental labs and practices. As a matter of fact, the popular clear aligners, thermoformed on 3D printed molds, are possibly the single most successful use of 3D printing we've seen to date.

Over the past ten years, 3D printing has so advanced in dental that now no new dental labs are opening without using some form of digital dentistry. With materials so good they can 3D print permanent crowns, full dentures, and more.

3D printing technologies thrive in an environment where our unique bodies require custom solutions. As a result, the dental industry is going through a rapid digital transformation with digital workflows bringing increased efficiency, consistently high quality, and lower costs to dental labs and practices.

Five Ways 3D Printing Has Redefined the Dental Industry

Next time you’re out for a night on the town, keep your eyes peeled for our next unexpected 3D printing use-case: 3D printing is coming to custom glasses frames.

Marcus Marienfeld AG set themselves apart from conventional glass frames, using different and unique production techniques to create their frames. Recently they started integrating selective laser sintering (SLS) 3D printing into the production line for frames in their Swiss workshop for printing end-use parts and rapid tooling for forming titanium.

“You get very inventive and imaginative when you have a 3D printer in-house. I can do things with little effort that I wouldn't otherwise try," said Marcus Marienfeld.

See the 3D Printed Glasses

Visualizing 3D printing-driven changes in the way things are made does not require the feats of imagination it once did. As workflows have developed over the last several years and gained footholds in various industries, we are beginning to see that revolutionary potential demonstrated.

From dentistry and across healthcare to consumer goods, architecture, and manufacturing, the public is interacting more and more with the end products of 3D printing. Making custom parts cost-efficient, cutting lead times and overheads, and empowering customers by bringing them closer to the products they want—we can only expect the influence of 3D printing to continue expanding.

Top 3D Printing Applications Across Industries

4. Construction

Construction 3D printing offers various technologies that use 3D printing as the main way of fabricating buildings or construction components.

3D printing applications that are used in construction include extrusion (concrete/cement, wax, foam, and polymers), powder bonding (polymer bond, reactive bond, sintering) and additive welding. 3D printing in construction has a wide array of applications in the private, commercial, industrial and public sectors. Advantages of these technologies include allowing more complexity and accuracy, faster construction, lower labor costs, greater functional integration, and less waste.

The first fully completed residential building was constructed in Yaroslavl, Russia in 2017. 600 elements of the walls were printed in a shop and assembled on site, followed by completion of the roof structure and interior decoration for a total area of 298.5 sq meters (3213 sq ft). The project represents the first time in the world the entire technological cycle had passed building requirements, from design, building permit, registration, to connection of all engineering systems. The building was not built just for presentation, today a real, normal family lives in it.

Concrete 3D printing has been in development since the 1990s, as a faster and less expensive way of constructing buildings and other structures. Large-scale 3D printers designed specifically for printing concrete can pour foundations and build walls onsite. They can also be used for printing modular concrete sections that are later assembled on the job site.

In 2016, the first pedestrian bridge was 3D printed in Alcobendas, Madrid, Spain. It was printed in micro-reinforced concrete at a length of 12 meters (39 ft) and width of 1. 75 meters (5.7 ft). The bridge illustrates the complexities in the forms of nature and was developed by both parametric (using a set of rules, values, and relationships that guide the design) and computational design, allowing the optimal distribution of materials while maximizing structural performance.

It was a milestone in the international construction industry, being the first large-scale application of 3D printing technology in the field of civil engineering in a public space.

3D printing is used to produce architectural scale models, enabling a faster turnaround of the scale model and increasing the overall speed and complexity of the objects produced.

As a futuristic concept, 3D printing is being studied as a technology for constructing extraterrestrial habitats, such as habitats on the Moon or Mars. It has been proposed, using building-construction 3D printer technology, fabricating lunar building structures with enclosed inflatable habitats for housing human occupants inside the hardshell lunar structures. These habitats would need only ten percent of the structure to be transported from Earth, using local raw lunar materials for the other 90 percent of the structure.

5. Art and Jewelry

An unexpected application of 3D printing technology has been in the world of art and jewelry making.

3D printers allow jewelry makers to experiment with designs not possible with traditional jewelry making methods. 3D printing also allows the production of individual, unique pieces of jewelry or customized pieces at a much lower cost, using 3D printing materials such as PLA (polylactic acid filament), gold or platinum.

3D printing technology has served to inspire artists all over the world. With metal 3D printing especially, artists now create beautiful intricate pieces.

Just a few examples of 3D printing technology in the arts include Banksy, the mysterious and famous British street artist, whose works’ have been rendered from 2D to 3D using powder binding 3D printing.

The Dutch artist Oliver van Herpt creates ceramic vases with 3D printing. From the Netherlands, Danny van Ryswyk creates eerie 3D printed sculptures, reminiscent of filmmaker Tim Burton’s characters. The digital artist Gilles Azzaro even makes the invisible visible by creating 3D images of voices using the sound waves from the voices.

Recently, the Prado Museum organized an exhibition of paintings by well-known artists rendered in 3D. The purpose was to allow visually impaired people to feel these works that were previously inaccessible to them.

These are just a few of the countless ways, from education to medicine to industry to the arts, that 3D printing technologies impact our world today.

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.

1. Economy

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.

4. Less waste

The press is gaining more and more support in the form of supporters of the "green" movement. Because 3D printing produces significantly less waste than traditional processing, the technology is more environmentally friendly while reducing costs. 3D printing has even made its way into the textile industry, allowing clothing and prototypes to be printed.

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.

Functional parts printed on Hercules. Material ABS, nozzle diameter 0.5 mm, layer height 150 µm, filling 100%. The model consists of 3 parts: the body and 2 halves of the latch, after printing and processing, the parts were glued together with acetone.

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.

8. 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.

THE PAST, PRESENT AND FUTURE OF 3D PRINTING

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.
