Bioprinting organs one step at a time: The special challenges of the 3D printed kidney as reflected in morphology Patricia Bacus
What can we make with 3D printers now?• Coffee cups
• Toys
• Your phone case
• Clothing
• Guns
• Organs
How did we get to where we are today?• 1984: Charles Hull invents stereolithography
• 1992: starting to add layers to the objects
• 1999: engineered organs start making advances
• 2008: Breakthrough for prosthetics
• 2009: from cells to blood vessels
• 2012: A printed jaw is implanted into a patient
Bioprinting• 3 common types• Inkjet 3D bioprinting
• Microextrustion 3D bioprinting
• Laser- Assisted 3D bioprintning
Other types• Stereolithography
• Two-Photon Laser Lithography
• Selective Laser Sintering
• Fused Deposition Modeling
• Powder Binding
• Polyjet
• Syringe Deposition
Limitations and Challenges • The need for vascularization
• Functionality
• Size
• Complex architecture
• Innervation
• Cost
