What Kind Of 3D Printing Technology Is Employed in The Healthcare Industry?

The healthcare industry utilises several types of 3D printing technologies to create various medical devices, implants, prosthetics, and anatomical models. Among the prevalent 3D printing technologies frequently employed in the healthcare sector are:

  • Fused Deposition Modelling (FDM): FDM is one of the most widely used 3D printing technologies. It works by extruding a thermoplastic material through a heated nozzle, solidifying as it cools. FDM is used to create patient-specific anatomical models, surgical guides, and some custom implants.
  • Stereolithography (SLA): SLA uses a liquid resin cured by a laser or UV light, layer by layer, to create the final object. SLA is known for its high detail and precision, making it suitable for creating highly accurate anatomical models, dental appliances, and surgical guides.
  • Selective Laser Sintering (SLS): SLS utilises a high-powered laser to selectively fuse powdered material (often a polymer) layer by layer. It is commonly used to create complex and durable objects, such as prosthetic limbs, orthopedic implants, and anatomical models.
  • PolyJet Technology: PolyJet employs multiple printing nozzles to deposit layers of liquid photopolymer onto a build tray, subsequently solidifying them using UV light.This technology can produce highly detailed and multi-material objects, making it suitable for creating realistic anatomical models, dental restorations, and surgical guides.
  • Digital Light Processing (DLP): DLP is similar to SLA in using a liquid resin cured layer by layer. However, DLP uses a digital light source (usually a projector) to cure entire layers at once, which can lead to faster print times. It is used for applications similar to SLA, such as dental models and surgical guides.
  • Electron Beam Melting (EBM):Electron Beam Melting (EBM) employs an electron beam to gradually liquefy layers of metal powder, thereby fabricating objects composed of diverse metals.This technology is used to produce custom metal implants, such as hip or knee replacements.
  • Laser Powder Bed Fusion (LPBF):LPBF, alternatively referred to as Direct Metal Laser Sintering (DMLS), employs a high-energy laser to selectively fuse metal powder layer by layer. It’s commonly used for producing complex metal implants and surgical instruments.
  • Bioprinting: Bioprinting is a specialised form of 3D printing that uses biological materials (such as living cells) to create tissue-like structures. It can potentially revolutionise areas like tissue engineering, organ transplantation, and pharmaceutical testing.

Each of these 3D printing technologies has its advantages and applications within the healthcare industry, enabling a diverse array of medical solutions that can be tailored to meet the unique requirements of each patient.

3D Printing Materials for Medical Industry

The healthcare industry has widely adopted 3D printing technology for various applications, from prototyping medical devices to producing custom implants. Several materials are commonly used in healthcare-related 3D printing processes. Here are some of them:

  • Bioinks: These are materials used in bioprinting, a branch of 3D printing that focuses on creating living tissues and organs. Bioinks typically comprise cells, growth factors, and a hydrogel matrix.
  • Metal Alloys: Titanium and cobalt-chromium alloys are commonly used in 3D printing for producing implants like hip and knee replacements. They are known for their biocompatibility, corrosion resistance, and high strength-to-weight ratio.
  • Polymers (Plastics): Various thermoplastic materials are used in 3D printing for medical devices, prosthetics, and anatomical models. For instance, ABS (Acrylonitrile Butadiene Styrene), PLA (Polylactic Acid), and PEEK (Polyether Ether Ketone) are commonly used for different applications.
  • Ceramics: Dental crowns, bridges, and other dental prosthetics are often 3D printed using ceramics. These materials can closely mimic the appearance and properties of natural teeth.
  • Hydrogels: These materials are used for bioprinting and are designed to mimic the properties of human tissues. They can be used to create scaffolds for tissue engineering and regenerative medicine applications.
  • Nylon (Polyamide): Nylon is used in 3D print for creating durable, flexible, and impact-resistant medical devices. It is often used in applications like orthotics, prosthetics, and surgical instruments.
  • PEEK (Polyether Ether Ketone): PEEK is a high-performance polymer known for its excellent mechanical properties, biocompatibility, and chemical resistance. It is used for creating custom implants and surgical guides.
  • Photopolymer Resins for Surgical Guides: These resins are used to create accurate and sterilisable surgical guides for procedures like dental implant placement.
  • Alginate: This biocompatible material is used in medical 3D printing, particularly in creating moulds for body parts. It is often used in prosthetic and orthotic applications.

It’s worth noting that the choice of material depends on the specific application, regulatory requirements, and the intended use of the 3D-printed item in the healthcare context.
