From rapid prototyping to revolutionary manufacturing, 3D printing technology has evolved tremendously since its inception. When I first encountered industrial 3D printers back in 2015-16, I was surprised by the wide variety of applications of 3D printing. I was struck by how quickly the technology was moving beyond simple prototyping into functional, end-use applications. In a decade years, I’ve watched the industry transform from primarily creating concept models to manufacturing flight-critical aerospace components.
Today, 3D printing spans countless sectors, revolutionising how we design, create, and manufacture products across diverse industries. While prototyping remains its most common application, the technology now offers solutions that traditional manufacturing simply cannot match in terms of complexity, customisation, and speed.
3D Printing Techniques and Innovations
The additive manufacturing landscape has expanded dramatically with technological advancements driving innovation across multiple printing techniques. Some of those technologies include:
- Fused Deposition Modelling (FDM): The most affordable and widely used 3D printing technology. It extrudes thermoplastic filaments layer by layer to form a solid part.
- Stereolithography (SLA): It uses UV-curable resins to create highly detailed parts with smooth surface finishes by curing them through lasers (projectors in case of DLP or Digital Light Processing technology.)
- Selective Laser Sintering (SLS): This technology uses powdered polymer materials where individual particles are fused together thought the applications heat via powerful CO2 lasers.
- Direct Metal Laser Sintering (DMLS): Similar to SLS, DMLS uses powdered metal materials where individual particles are fused together thought the applications heat via powerful CO2 lasers producing high-strength metal components for critical applications.
- Selective Laser Melting (SLM): These are similar types of powder bed fusion metal 3D printing technologies. SLM technology also uses powdered metal material with lasers to fuse the adjacent particles. The difference between SLM and DMLS is in application of heat. In SLM, the particles are melted rather than sintering (like in the case of DMLS).
- Electron Beam Melting (EBM): Similar to SLM, but in this technology the material is melted using electron beam.
According to the Wohlers Report 2025, the global additive manufacturing market is valued at $21.9B and is growing at a CAGR of 20.23%. It is expected to reach $115B by 2034. This acceleration in adoption will be fuelled by rapid adoption and integration of AL & ML to enhance various aspects of AM, including design optimization, process control, and quality assurance, advancements in materials science, application centric solutions to advance adoption and more.
Applications of 3D Printing Technology

The aerospace industry stands as one of the earliest and most enthusiastic adopters of additive manufacturing technology. In 2014, SpaceX achieved a significant milestone when they successfully hot-fired their 3D printed SuperDraco engine chamber, made from Inconel, a high-performance superalloy. This innovation dramatically reduced production time from months to weeks while maintaining exceptional structural integrity.
The May 2020 collaboration between SpaceX and NASA marked a historic moment when two astronauts were sent to the International Space Station in SpaceX’s Crew Dragon spacecraft, equipped with the 3D printed SuperDraco engine. According to NASA’s published technical reports, these engines delivered 16,000 pounds of thrust with extraordinary reliability, largely attributable to the reduced part count and elimination of joining weaknesses inherent in traditional manufacturing.
In India, Startups like Skyroot Aerospace and Agnikul Cosmos are also using and developing 3D printed rocket engines and have even successfully tested them for space use. ISRO, the Indian space agency, also is now heavily investing in 3D printing technologies and is taking an initiative to contribute 10% of components through 3D printing in their future flights
Other aerospace giants including Boeing, Airbus, and GE Aviation have invested heavily in 3D printing capabilities. GE Aviation’s 3D-printed fuel nozzles for the LEAP engine reduce the component count from 20 parts to just one, while being 25% lighter and five times more durable, according to their 2022 technical publication.
In Automotive
The automotive industry has adopted 3D printing since a long time. Thought it was majorly for prototyping but still that paved the way for other industries to take notice. But now the adoption has moved from just prototyping to even end-use parts. Some of the biggest companies have incorporated 3D printing into their product development workflow.
BMW Group with their IDAM (Industrialisation and Digitalisation of Additive Manufacturing) project, has successfully integrated additive manufacturing into their series production workflow. A project consortium funded by the German Federal Ministry of Education and Research (BMBF) and led by the BMW Group was launched in 2019, with small and mid-sized enterprises, large companies and research institutes. The common goal was to revolutionise metal 3D printing in standard production of cars.
As per a 2022 post, around 50,000 components per year were manufactured cost-effectively in common part production, as well as more than 10,000 individual and new parts, by means of 3D printing using Laser Powder Bed Fusion (LPBF).
Companies like Ford, Mercedes, Honda, Lamborghini, Porsche, and General Motors are some of the early adopters in Auto sector.
In Medical/Healthcare
Medical applications of 3D printing represent some of the most promising and life-changing implementations of this technology. The healthcare sector recognised the potential of additive manufacturing early, with researchers at the Wake Forest Institute for Regenerative Medicine successfully implanting 3D-printed synthetic bladder scaffolds in human patients as early as 1999, as documented in their landmark paper published in The Lancet.
Similarly there have been many accomplishments in this space that are no less than science fiction stories we all might have read.
In 2019, researchers at Tel Aviv University achieved a remarkable breakthrough by creating the world’s first 3D printed heart using human tissue.
Professor Tal Dvir, who led the research team, explained: “This is the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers.” The implications for personalized medicine are profound, potentially addressing the chronic shortage of donor organs.
In 2022, a human has received a 3D-bioprinted ear implant grown from the patient’s own living cells – thanks to a technology platform developed by a Cornellian-founded Startup company.
In 2024, India’s Incredible 3D achieved a significant milestone of successfully 3D printing 3000+ patient specific implants.

In Jewellery
This centuries-old industry, relying on techniques like investment casting dating back 4,000 years, has embraced additive manufacturing to enhance rather than replace traditional craftsmanship.
Premium jewellery has always been a reflection of amount of effort that goes into creating that piece of art. It has been heavily dependent on the work of skilled artisans that have been passing on their knowledge and skill to the next generation. This labour intensive sector also now has a competition from 3D printing.
With 3D printing, the effort of creating complex pieces of jewellery are literally eliminated. Only the CAD designs are now required and affordable printers can also turn that design into a plastic part which is further casted to make a final jewellery in any precious metal.
This also means that the jewellery can be easily customised to fit any one form children to adults and is possible to be produced significantly faster than traditional methods.
The technology has democratized jewellery design, allowing creators to:
- Rapidly prototype complex designs before committing to precious metals
- Create intricate lattice structures and geometric patterns impossible with traditional methods
- Produce custom-fitted pieces with precise dimensions
- Reduce material waste in the casting process by up to 40%
In Art/Sculpture
The intersection of 3D printing and fine art has produced some of the most innovative creative expressions of the 21st century. The Museum of Modern Art’s 2021 exhibition “Designed by Algorithm” featured over 50 3D printed sculptures that challenged conventional notions of artistic creation, with pieces that could not have been realized through any other manufacturing method.
The Victoria and Albert Museum in London now maintains a permanent collection of 3D printed art, recognizing its significance in contemporary creative expression. According to their curator of contemporary design, these works represent “a fundamental shift in how we conceive of making, challenging traditional distinctions between designer, manufacturer, and artist.”
Dr. Michaella Janse van Vuuren, an artist with a PhD in Electrical Engineering, combines her technical expertise with artistic vision to create pieces that blur the line between technology and traditional craftsmanship. In her 2022 interview with Sculpture Magazine, she noted: “3D printing doesn’t replace artistic skill – it demands a completely new set of skills, merging digital fluency with spatial understanding and material knowledge.”
Notable 3D print artists have emerged as pioneers in this new medium. Joshua Harker, widely regarded as a visionary in 3D printed art, creates intricate sculptures with seemingly impossible geometries. Dutch kinetic artist Theo Jansen uses 3D printing to develop components for his remarkable “Strandbeests” – wind-powered mechanical creatures that walk autonomously along beaches.
