InssTek announces new 3D printing milestones for medical and aerospace applications

0Shares

Korean metal 3D printing company InssTek has announced a couple of significant milestones achieved with its various Direct Energy Deposition (DED) additive manufacturing technologies.

InssTek is proficient in Direct Metal Tooling (DMT) technology, having previously deployed it to repair parts of the South Korean Air Force’s F-15K fighter jets. Back in 2016, the company teamed up with Z3DLAB France to offer its customers the best in advanced materials for aerospace parts repair and medical implants. The company’s MX 1000 metal 3D printer was also the crowning glory of the Skolkovo Institute of Science and Technology (Skoltech)’s Additive Manufacturing Laboratory upon its opening in 2017.

Now, the company’s technologies have contributed to the fabrication of a 3D printed artificial hip joint that has received approval from the US Food and Drug Administration (FDA), and to the production of a multi-material rocket nozzle for the aerospace sector.

Receiving FDA approval

The first new development from InssTek is a 3D printed artificial hip joint and cup component, fabricated using its Metal Porous Coating (MPC) technology. MPC is a DED additive manufacturing technique that works by 3D printing patterns of porous structures onto the surface of artificial joints using medical-grade titanium powder.

The method differs from conventional techniques by melting and combining the artificial joint and titanium powders together to form one alloy, of which the optimal roughness and pore structure can be achieved.

Using its MPC technology, InssTek successfully coated a BENCOX Mirabo Z Cup Cortinium artificial hip joint cup manufactured by Korean artificial limb developer Corentec. The artificial joint has since received FDA approval, prompting InssTek to apply its MPC technology to cobalt-chromium alloys for artificial knee and ankle joints.

The company is currently carrying out further research into how it can leverage MPC for various other industrial applications within the semiconductor and aerospace sectors.

3D printing has the potential to enable faster and more accurate surgeries, particularly regarding titanium materials that have already been verified for biocompatibility. Just recently, a group of researchers from Korean hospitals carried out a study to verify the effectiveness and safety of 3D printed patient-specific titanium implants on maxillofacial bones, while Health Canada approved its first 3D printed titanium medical implant in December.

Multi-material 3D printing

The second development announced by the firm involves the successful 3D printing of a rocket nozzle for the aerospace sector.

Due to the extreme environments aerospace parts, and in particular rocket nozzles, operate within, the parts often have several varying requirements. For instance, within a rocket nozzle, the working temperature and heat flow are different in the lower and upper regions of the part and therefore require different materials for optimal performance.

As a result, there is increased demand within the aerospace sector for the use of different materials in a single part, however binding two different materials together still proves a challenging feat in terms of surface adhesion, weakness, and instability. As a result, many metal 3D printing technologies tend to manufacture parts in a single material, which is where DED-based methods come into their own.

The InssTek team sought to leverage DED to explore how gradually changing the composition of a material could improve its stability and capability to meet the demand of harsher applications.

To this end, the team deployed its Functionally Graded Material (FGM) technology, a novel DED additive manufacturing technique that combines two materials and gradually alters their composition to produce a multi-material part.

Crucial to the success of the technique is InssTek’s CVM Powder Feeding System, which is designed to ensure stable powder supply during the metal 3D printing process. The system can monitor powder supply in real-time and is capable of controlling up to six different powders at any one time.

Using its FGM method, CVM Powder Feeding System and other material processing technologies, InssTek was able to successfully 3D print a scaled rocket nozzle. The success of the project has prompted the firm to continue researching the application of multi-material metal parts to other fields, such as the aerospace, marine, and medical sectors.

InssTek will be showcasing its new developments, including its MPC technology, at the upcoming IMTS show in Chicago in September and at Formnext in Germany shortly after.

InssTek, a metal DED technology developer based in Daejeon, South Korea, succeeded in manufacturing a multi-material Functionaly Grade Material, or FGM, rocket nozzle using different metals (aluminum-bronze alloy and stainless steel) in a single print run. This application proves that aerospace components used in extreme environments can be made using the ideal materials with superior characteristics in each different region of the same part. As confirmed by NASA and other space companies, the ability to produce single parts using different metals is expected to be a key enabling technology for the growing space industry market.

Many aerospace components are used in extreme environments. Rocket nozzles in particular have different requirements with many different parameters. For example, the working temperature and heat flow are different in the upper and lower regions of the nozzle, thus the preferred types of materials may vary for each region.

While this has led to an increasing demand to apply different materials in each area of the same part, the ability to safely and effectively bind together the two different materials remains a challenge, with the contact becoming too weak due to the difference in characteristics of each material. Innstek demonstrated that when the composition of the materials is changed gradually, through the precision of metal deposition AM technology, it can produce a more stable material that can withstand harsher conditions in extreme applications.

Thus, Functionally Graded Material (FGM) approach was demonstrated by Insstek as a novel method of combining two metal materials, gradually changing the composition of the two different materials to produce a multi-material part.

Most metal 3D printing technologies such as casting, forging, and cutting, manufacture parts with a single material. However, Direct Energy Deposition (DED) offers a significant advantage by enabling the use of multiple materials. When 3D printing with multi-materials, the most important technology is the “Powder Supply” technology. It should supply stable quantities for a long time throughout the print and also supply multiple powders at the same time, as the properties of a metal alloy can be easily changed by the composition of the different elements. Thus “Accurate Control ” and “Multiple Powder Feeding” technology is essential.

InssTek’s CVM Powder Feeding System technology does just that: it provides a more stable powder supply during the metal 3D printing process. It can be controlled within ±5% of the target amount by monitoring the powder supply in real-time. In addition, it is an optimized technology for manufacturing multi-material parts with a new composition by independently controlling up to six different powders.

InssTek has its own HW, SW, and material processing technologies that can be used to manufacture multi-material parts. Based on these technologies, InssTek succeeded in producing the actual scale rocket nozzle into Functionally Graded Material. Research is underway to apply multi-material parts to diverse fields such as aerospace, marine, and medical industry.

InssTek will be exhibiting at IMTS, in Chicago this September, and at Formnext in Frankfurt, Germany, this November to showcase various metal 3D printing technologies, including its Multi-Material Manufacturing capabilities.
