Although 3D printing has existed for many decades, its popularity and use has increased in recent years. While there are always new 3D printing applications being developed, the following applications have gained popularity recently.
The recent rise in 3D printing usage is due in large part to the fact that it is an easy technology that can be used across a variety of applications. 3D printing was expensive to start in its early years. The 3D printer models were costly, as were the materials. With improvements in both the technology of the machines and the materials used in them, the costs have fallen in recent years. This has made 3D printing more affordable and more cost-effective across all industries.
1. EDUCATION
Immersive 3D printing is becoming more popular in schools. 3D printing is an tool that allows students to make prototypes and save money. 3D printing is a way for students to learn by creating and holding models.
3D printing allows for the creation of ideas/images in a physical, 3-dimensional world.
3D printers can now be found in public libraries and classrooms. Students can use 3D printers in class and on projects at universities.
3D printing tools have also revolutionized STEM education. They allow students to quickly prototype low-cost equipment in their classrooms, and they can also fabricate low-cost, high-quality scientific equipment using open-source hardware designs.
Through exploring engineering, design, and architectural principles, students learn about Applications of 3D Printing. They can reproduce museum items such as fossils and other historical artifacts in the classroom, without causing damage to fragile collections. They can see topographic maps from a different perspective.
Students in graphic design can create models with many working parts. Science students can study cross-sections of organs and other biological specimens. Students in Chemistry can create 3D models and chemical compounds.
2. PROTOTYPING & MANUFACTURING
3D printing was originally developed to speed up prototyping. A traditional injection-molded prototype can cost hundreds of thousands and take weeks to make. This is not practical if you want to improve your design with every iteration. The lead time for traditional manufacturing is significantly reduced by 3D printing technology. A prototype can be made in hours and not weeks. It also costs a fraction of what it would cost. Manufacturing using 3D printing technology is not limited to the aerospace and automotive industries.
Traditional manufacturing is more cost-effective for large quantities. 3D printing, also known as additive manufacturing in manufacturing circles, is a great option for products that are not being mass-produced. It allows for relatively low-cost production in smaller quantities or on a case by case basis. Rapid prototyping (RP), which is a technology that allows for rapid prototyping, has led to the development and application of materials and processes such as Selective Laser Sintering, Direct Metal Laser Sintering, and DMLS, that can be used to produce the final product and not just the prototype. This is Rapid Manufacturing.
Cloud computing technology is so widespread today that companies offer cloud-based additive production services, where customers can create parts remotely from their computers without having to purchase a 3D printer.
Mass customization services are now offered by companies. Customers can personalize objects using simple web-based software and order the resultant items (e.g. mobile phone cases) as unique 3D printed objects.
The agile tooling has been created by 3D printing technology. This modular design allows for quick prototyping and rapid responses to fixture and tooling needs.
3. MEDICINE
There have been many 3D printing applications within medicine in recent years. These range from Bioprinting, where cells and growth factors combine to create tissue-like structures that imitate their natural counterparts, to medical devices such as prosthetics.
3D printed prosthetics are a great example of 3D printing's versatility. Prosthetics that fit the patient's needs are difficult and costly to make. The cost of 3D printing allows for the creation of prosthetics that are precisely measured and printed at a significantly lower price. To ensure that they wouldn't outgrow the prosthetic, children who needed one had to wait. A new prosthetic can now be 3D printed every few months. Protheses used to be a problem in some countries of the third world, but they are now possible with 3D printing.
For the production of metal orthotic implants, 3D printing is also used in medicine. These implants can be integrated with patients' natural bones and allow them to grow because of the porous nature of 3D printing.
One patient received a titanium pelvis implant and another received a new titanium lower-jaw. Motorcyclist patient who had suffered severe injuries in a crash on the road had his face rebuilt using 3D-printed parts.
Bio printing is a 3D printing technology that allows the creation of artificial organs. This helps to solve organ failure problems faster for patients. It is important for both the patient and the family as well as the healthcare system.
For pharmaceutical testing, 3D printed tissues were created as a cost-effective way to identify side effects and validate safe dosages.
Binder Jetting is a 3D printing process that allows for the production of pills. This allows for very porous pills, which makes it possible to make high doses of pills in one pill. It is useful for treating epilepsy and other conditions.
4. CONSTRUCTION
3D printing for construction offers a variety of technologies that use 3D printing to make buildings and other components.
Construction uses 3D printing for extrusion, wax, foam and polymers, as well as powder bonding (polymer bonds, reactive bonds, sintering, and additive welding. There are many uses for 3D printing in construction, including in the public, private, industrial, and commercial sectors. These technologies offer many advantages, including greater complexity and accuracy, faster construction and lower labor costs. They also allow for greater functional integration and less waste.
In Yaroslavl (Russia), the first residential building was completed in 2017. 600 walls elements were printed in a shop, assembled on-site and covered a total of 298.5 square meters (321 sq ft). This project is the first to pass all the requirements of building permits, design, registration and connection. It was not just a building for display, it is now home to a normal family.
Concrete 3D Printing is a fast and affordable way to build buildings and other structures. It has been around since the 1990s. Concrete 3D printers are large-scale machines that can print concrete. They can also be used to build foundations and walls on the spot. These printers can also be used to print modular concrete sections, which are then assembled on-site.
The first pedestrian bridge was printed 3D in Alcobendas (Madrid, Spain) in 2016. It was printed in micro reinforced concrete with a length 12 meters (39 feet) and a width 1.75 meters (5.9 feet). This bridge illustrates the complexity of the forms found in nature. It was created using both parametric (using a set rules, values and relationships that guide design) and computational design. This allows for optimal material distribution and structural performance.
This was an important milestone in international construction, as it was the first large-scale use of 3D printing technology for civil engineering in public spaces.
3D printing allows for the production of architectural scale models. This speeds up the turnaround time and increases the complexity and speed of the objects.
3D printing is being explored as a futuristic technology to construct extraterrestrial habitats such as those on Mars and the Moon. It has been proposed, using building-construction 3D printer technology, fabricating lunar building structures with enclosed inflatable habitats for housing human occupants inside the hard-shell lunar structures. These habitats could be built using only 10% of the structure and local lunar raw materials for the remaining 90%.
5. ART AND JAWELRY
3D printing technology is being used in unexpected places, such as jewelry and art.
Jewelry makers can create new designs with 3D printers. 3D printing allows for the creation of unique, customized jewelry at a lower price. It uses 3D printing materials like PLA (polylactic acids filament), gold, and platinum.
Artists all over the globe have been inspired by 3D printing technology. Metal 3D printing is a great way to create intricate pieces.
