Additive manufacturing is a powerful industrial technology that builds structures layer by layer, whether for making rapid prototypes during product development in automotive applications or high-performance parts for aerospace. Shapeways additive manufacturing services are set apart from traditional techniques because they provide engineers and designers with the ability to push the boundaries in innovation, the freedom to iterate and test as needed, and ultimately, with the tools for producing unique products never possible before.
Additive manufacturing services work in direct contrast to conventional manufacturing where subtractive measures are taken to remove material in making a part. This technology is also faster, with little need for lead times or tooling, exponentially less waste in material during production, and the option to experiment with a wide range of materials, methods, colors, and finishes.
The inception of additive manufacturing (1983) is formally accredited to Charles W. Hull, an engineer who went on to form the iconic 3D Systems in 1986 and to produce the first Stereolithography 3D printer in 1987. There were numerous forerunners to what we know as 3D printing, however, harkening as far back as the 1800s with more rudimentary 3D modeling and 3D printing creations like photographic sculptures and layered 3D topographical maps.
Another scientist, Dr. Hideo Kodama of The Nagoya Municipal Industrial Research Institute, even pre-dated Hull in the early 1980s with a photopolymer rapid prototyping process. Hull was, however, the owner of the first 3D printing patent, and he continued from there with undeniable dedication and success in what eventually became a thriving additive manufacturing industry. Chuck Hull also single-handedly established the modern concept of rapid prototyping, allowing every generation thereafter to enjoy improved and accelerated product development.
Veering in the opposite direction of conventional manufacturing and subtractive processes, Hull was originally experimenting with the idea of creating parts by applying one layer of material coating on to another to form a solid structure. Combined with his knowledge of CAD software, the process evolved into SLA 3D printing with resin materials cured layer by layer via an ultraviolet laser.
The significance of Hull’s invention was not lost on forward-thinking organizations like NASA or a handful of automotive companies with the resources to begin investing in the technology. Additive manufacturing was in play behind the scenes for decades before finding its way into the mainstream. As patents began to expire around 2014 though, 3D printing was thrust into the spotlight as a revolutionary new tool. The technology gained tremendous traction, becoming popular among designers and engineers who were suddenly empowered with the ability to design and develop innovative products on their own time. By then, many other 3D printing technologies had emerged too, from desktop 3D printing with Fused Deposition Modeling (FDM), to other advancing industrial technology like Selective Laser Sintering (SLS), and even bioprinting.
SLA 3D printing is still considered to be powerful, and highly respected. Shapeways designers typically turn to SLA for creating intricate 3D models, master patterns for traditional manufacturing like Injection Molding, and detailed parts for rapid prototyping or 3D printing functional parts.
Rapid prototyping takes the design process from a sketch to an actual product much more quickly when comparing additive manufacturing vs. traditional methods, which could sometimes result in months between 3D models.
3D design and slicing software is highly accessible, allowing Shapeways designers to create 3D digital files and prototypes they can easily adjust for better aesthetics, fit, functionality, and scale. A streamlined 3D modeling process is extremely valuable for Shapeways customers later too as they may need to make numerous prototypes for testing. For some 3D designers, only one or two prototypes are necessary, while others may need many more.
Rapid prototyping is economical with materials like Nylon 12 [Versatile Plastic] but it is possible to use these advanced, high quality materials for functional products. This adaptability in materials and technology has furthered the evolution of additive manufacturing significantly. 3D printing from product development to manufacturing saves time, costs, and means that manufacturers can take their ideas and products to market and get them into the hands of their customers faster.
A manufacturing partnership with Tilt Hydrometer serves as a great example of the power of prototyping with Shapeways. CEO Noah Neibaron has no problem with iterating over a hundred times if necessary, and he did so while perfecting Tilt’s free-floating hydrometer for measuring fermentation. 3D printing Nylon 12 [Versatile Plastic] with SLS technology, Tilt Hydrometer used the same durable material for prototyping as they did for their final, high-performance products. They also chose from the variety of different colors available through dyeing–using them to differentiate between sensors. Download the full case study here.

Multi-faceted materials like Nylon 12 [Versatile Plastic] continue to rank high in popularity. Also known as a 3D printing thermoplastic, this material is derived from the broader Nylon 12 family and other related polyamides–all featuring a long history in conventional manufacturing too. Nylon 12 is an industry favorite due to its unique material properties and reinforced formulations, offering great durability and tensile strength, as well as resistance to abrasion, chemicals, fatigue, and stress.
Featuring durability as well as heat resistance, Nylon 11 [PA11(SLS)] parts are 3D printed with Selective Laser Sintering (SLS) and built to last. Used for automotive, aerospace, drone, and even high-fashion applications, this 3D printing material is well-known for its ability to hold up to rigorous conditions like heat and weather. Nylon 11 [PA11(SLS)] is also impact-resistant, chemical-resistant, and heat-resistant up to 180°C.
For metal AM applications, Shapeways customers often select materials like Steel, innovating like never before with the ability to make extremely strong parts that are also lightweight, on any scale. Other more specialized materials like Multi Jet Fusion Plastic PA12 Glass Beads (MJF Plastic PA12GB) are commonly used for 3D printing medical devices like arm braces, as well as 3D printing large parts requiring added stiffness and structural integrity.
A variety of finishes are available from Shapeways too; for example, Nylon 12 [Versatile Plastic] finishing options include Natural, Processed, Premium, and Smooth. Parts can be dyed in eight different colors–while other full-color 3D printing materials like High Definition Full Color extend capabilities to over ten million hues with Standard or Matte finishes.
The BeeHero case study exemplifies why so many customers choose Nylon 12 [Versatile Plastic] for durability. BeeHero manufactures smart hives and uses their collected data to improve pollination in specific areas like almond farms. Shapeways had the privilege of working with BeeHero in their journey to save the bees, entering the picture as BeeHero began 3D printing their third-generation sensors encased in hardware and placed within the hives for monitoring.
BeeHero also chose Nylon 12 [Versatile Plastic] for its excellent mechanical properties, color, and texture, 3D printing with SLS technology to accommodate their requirements for receiving and then assembling the hardware in the smart hives onsite.
For the HeartBeatDress case study, Anouk Wipprecht shared another successful journey into fashion tech design with Shapeways. The HeartBeatDress displays the general mood or feelings of the wearer, flashing in time with the heart rate, translated onto a touch sensor embedded in a Swarovski crystal. Shapeways 3D printed the hip pieces for the dress, using Nylon 11 [PA11(SLS)] and SLS 3D printing. Wipprecht points out that for her fashion tech designs, she has seen the best results with that specific combination of advanced 3D printing materials and technology.
3D printed medical models have made a true impact in medical applications. Serving as multi-faceted tools, medical models relate to nearly every phase of treating a patient. Assisting in the diagnostics stage, additive manufacturing services help surgeons decide on a course of treatment and plan their surgeries, along with using the 3D printed visual aids to educate patients and their families. Surgeons and medical students also rely on 3D printed medical models to practice new procedures.
Many different technologies and applications are related or are complementary to each other, like additive manufacturing services and robotics. While some designers are busy 3D printing components for industrial robots engaged in applications like automotive and construction, others rely on robotic training tools 3D printed to prepare physicians around the world for new and delicate surgical procedures.
Soaring in popularity as well as the skies above, unmanned aerial vehicles represent one of the most exciting and innovative areas of additive manufacturing services. UAV designers focus on 3D printing drone frames that are sleek, lightweight, and capable of flying at ever-higher altitudes to survey real estate and agriculture, monitor difficult-to-access places on Earth, and carry increased payloads.
Armor Bionics designs medical models for 3D printing in Nylon 12 [Versatile Plastic] with Selective Laser Sintering. Described as a GPS for the surgeon, Armor Bionics’ 3D printed medical models pave the way for designing, planning, and operating. Surgeons report saving hours in pre-planning, while hospitals overall note greater efficiency in using the medical models. Both teams focus on their strengths as Armor Bionics brings excellence to 3D modeling, while Shapeways perfects the 3D printing–ultimately allowing surgeons to streamline surgeries around the globe.
Industrial design firm Flamingo Works teamed up with Shapeways to 3D print colorful simulators for medical training. Expanding far beyond their previous designs for industrial parts and robotic arms, Flamingo Works endeavored to create an innovative, gamified learning platform to train surgeons in robot-assisted surgeries. The designers chose to work with Nylon 12 [Versatile Plastic] and SLS 3D printing again due the success of previous projects, but also because of expanded design freedom, the need to manufacture many parts at once, and requirements for durability due to the repetitive use of the simulators.
Quantum-Systems began 3D printing with Shapeways upon inception of their drone design company in 2015, favoring materials like Multi Jet Fusion PA12 (MJF PA12) and Nylon 12 [Versatile Plastic] for unmanned aerial vehicles that must fly in all conditions, including extreme temperatures. During product development, 3D printing has allowed Quantum-Systems to reduce design and production cycles for all their drone technology, from the initial design phase and fast iteration of prototypes to preparing fully vetted parts that become functional end-use components. By 3D printing common parts like mounts, Quantum-Systems has seen an impressive reduction of weight.
Driving some of the oldest—and still most powerful—additive manufacturing methods, powder-based technology includes Binder Jetting, Multi Jet Fusion, Selective Laser Sintering, and Selective Laser Melting.
Most of these technologies have the basics in common, as a thin layer of powder is dispersed across the print bed with a heat source melting each subsequent layer together. Greater design freedom is available since supports are not required, and excess powder can be easily recycled too, supporting sustainability in resources. Complex structures are possible, promising precision and repeatability every single time.
Technology like Stereolithography—the first 3D printing process to arrive on the scene in the 1980s—is a popular choice for designers seeking great accuracy and detail in parts. SLA is just one resin-based technology though, contrasting with Material Jetting which is extremely accurate but distinctly different. Known as one of the fastest methods of 3D printing, MJ technology relies on photopolymer resins built layer upon layer until the desired structure is complete.
A wide range of technology is available for 3D printing metals as popularity continues to trend upward for highly industrial technologies like Binder Jetting and Selective Laser Melting. This includes Lost Wax Casting too, an ancient technique greatly modernized for production of luxury items like fine jewelry with complex shapes, interlocking parts, and even engravings.
As industrial designers and creators of luxury jewelry inspired by nature, Groen and Boothman designed a luxury bracelet series. Shapeways manufactured the parts via Wax Casting with Sterling Silver, which Groen and Boothman then polished professionally. Both the Water and Cosmic bracelets feature a hidden clasp mechanism and hinge in the 3D printed design too–exemplifying one of the greatest benefits in 3D printing, with the ability to engineer precise parts with interlocking features.
Derived from polymers which melt easily in both the layering and adhesive process in 3D printing, thermoplastics like Nylon 12 [Versatile Plastic] are extremely adaptable because of high ductility–presenting flexibility for thinner structures and rigidity for thicker designs. Other high-performing materials like Thermoplastic Urethane (TPU) are derived from Polyurethane powders meant to create 3D printed elastomeric parts with performance similar to Injection Molded products.
Manufacturers today may select popular 3D printing metal materials like Steel or Aluminum, or choose from a wide range of precious metals that include Gold, Silver, and Platinum. Metal materials continue to increase in use because it is possible to make extremely strong and durable products on any scale that are also incredibly lightweight.
With over 90 materials and finishes, Shapeways offers a versatile lineup of resources that includes specialized materials like High Definition Full Color, allowing customers to choose from over ten million different colors. For resin-based technology like SLA we also offer an array of materials like Accura 60, Accura Xtreme, and Accura Xtreme 200.
