3-D Bio-Printed Prosthetics

1. By-Lovnish Thakur

2. Introduction
A 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

3. Objective

4. Method
3D bioprinting systems can be-:
1) laser-based
2) 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.

5. CELL-INK 3D Printed Miniature Ears
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

6. Economic Feasibility & Market Potential
Year Cost of
cell(500ml)
2013 225
2014 217
2015 216
Bio-printer cost

7. 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

8. Strengths
1. Customization & Personalization
2. Huge market potential.
3. Provides several entrepreneurial
opportunities.
4.Freedom to experiment with
structures and materials
Weaknesses
1. Quality of the organs
printed
2. Technolgy is still in
prematured state
3. Expensive.
Opportunities
1. To make new software &
new machinery for
developing tissue
2. Active development of
biocompatible materials.
3. Customization of designs
based on customer needs
Threats
1. 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.

9. Application
Rebuilds skull with 3D printing technology
3D printing makes more precise Knee implants
Skin grafts
