Problem

2009: 154,324 patients waiting for organs
 27,996 patients received them (18%)

8,864 patients died waiting
 Approx. 25 people per day
Cost of surgery & follow up procedures in
2012: $300 billion
 Tissue Rejection & Immunosuppressants

3D Printing
“Sterolithography”
 Present day:

 $700 million industry
 $11 million invested in medical applications (1.6%)

Next 10 years:
 $8.9 billion industry
 $1.9 billion invested in medical applications (21%)
