3-D Bio-Printed Prosthetics
By-Lovnish Thakur
IntroductionA prosthesis is a functional replacement for an
amputated or congenitally malformed or missing limb
Printed by a 3-D Printer using Bio-Ink.
3-D Printing Tissue Engineering
Objective
Tissue or organ failure due to aging, diseases, accidents, and birth defects is a critical medical problem
3-D PRINTING ALLOWS DOCTORS AND ENGINEERS TO PARTNER & TO REBUILD BODY PART (LIMBS) FASTER .
Method 3D bioprinting systems can be-: 1) laser-based2) inkjet-based
Process
•Deposits “bioink,” droplets of living cells or biomaterials, onto a substrate according to digital instructions to reproduce human tissues or organs.•Multiple printheads can be used to deposit different cell types (organ-specific, blood vessel, muscle cells.
CELL-INK 3D Printed Miniature Ears
• COMPANIES- ORGANOVO & BIOBOTS BUILDS MACHINES CAPABLE OF PRINTING REAL HUMAN
TISSUE CELL-INK create a standard
for the 3D bioprinting industry, with their newly universal bioink which is
aimed at 3D printing: living and fully functional 3D tissue
models
Economic Feasibility & Market Potential
Year Cost of cell(500ml)
2013 225
2014 217
2015 216
Bio-printer cost COMMERCIAL AREAS
Case study-Bioprinting of Kidney
•Cost of Kidney Transplant : $ 80,000 USD • Cost for Bioprinting of Kidney : $ 280,000 USD
Takes around 10 hours to bio-print a Kidney
Strengths1. Customization &
Personalization2. Huge market potential.
3. Provides several entrepreneurial opportunities.
4.Freedom to experiment with structures and
materials
Weaknesses1. Quality of the organs printed
2. Technolgy is still in prematured state
3. Expensive.
Opportunities1. To make new software & new machinery for
developing tissue2. Active development
of biocompatible materials.
3. Customization of designs based on customer needs
Threats1. Feasibility of Use in
the Real World 2. Questions of liability
3. Ethical Concern-In wrong hands, may contribute to fake
identity, increase in crime and illegal
activities.
Application
Rebuilds skull with 3D printing technology
3D printing makes more precise Knee implants
Skin grafts
