Simple, Vascularized Tissues

These can already be printed and used in research or for specialized medical applications. They are typically simpler structures that don’t require a complex internal blood-vessel network.

  • Skin grafts
  • Cartilage (nose, ear, joint patches)
  • Bone scaffolds
  • Corneal tissue
  • Meniscus tissue

B. Mini-Organs (“Organoids”)

Organoids are small, functional versions of organs used for drug testing and personalized medicine. They behave like miniature organs but are not large or complex enough to replace a full organ in the body.

  • Liver organoids
  • Kidney organoids
  • Pancreas organoids
  • Brain organoids (for disease modeling)

They are powerful tools for research and drug discovery, but they cannot yet serve as full transplant organs.

C. Bio-Printed Implants

Some 3D-printed or bioprinted implants are already approved or in late-stage trials. These are often made of biocompatible materials and may include cells, but they are not full standalone organs.

  • Custom airway splints for infants
  • Custom jaw bones
  • Patient-specific heart valves
  • Printed spinal implants
  • Customized dental structures
