Bioprinting is an additive manufacturing process where biomaterials such as cells and growth factors are combined to create tissue-like structures that imitate natural tissues. ... In essence, bioprinting works in a similar way to conventional 3D printing. A digital model becomes a physical 3D object layer-by-layer

3. 3D PRINTING IS TURNED
AS ‘BIO-PRINTING’ FOR
BIOMEDICAL ADVERTISE
3D PRINTING IS THE MOST COMMON AND RECENT
TECHNOLOGY FOR DEVELOPING THE
PHYSIOLOGICAL MODEL WHICH IS USED AS AN
IMPLANTABLE ARTIFICIAL TISSUE OR ORGANS.

4. What is 3D Printing?
A 3D
printer essentially work
s by extruding molten
plastic through a tiny
nozzle that it moves
around precisely under
computer control.
It prints one layer,
waits for it to dry, and
then prints the next
layer on top

5. 3D PRINTING
3D printing is becoming
popular in the customisable
gifts industry, with
products such as
personalized models of art
and dolls, in many shapes:
in metal or plastic, or as
consumable art, such
as 3D printed chocolate.

6. 3D bioprinting is thrilling
because of its potential to
develop living human tissue
which can be used for
clinical trials and to 'treat'
patients.

7. first bioprinters were
developed in 1984 by
Charles Hull , who
patented the
stereolithogra- phic
method.

8. PROCESS IN BIOPRINTING

11. PRE-PROCESSING
The physicians are supposed to observe the patient’s body
physically with minor equipment such as stethoscope,
thermometer, sphygmomanometer, patient monitoring
system, etc, if the doctor finds difficulty in diagnosing
then the patient’s condition, then they are advised to
take scanning the internal organs by using computer
tomography scanners (CT scan) or magnetic resonance
imaging scanners (MRI scan).
BIOMEDICAL ENGINEERING

12. Reconstructing
THE CT SCAN AND MRI SCAN HAVE VARIOUS FEATURES SUCH AS AN
ABILITY TO PRODUCE NUMBER OF SLICING OF IMAGES TO HELP THE
PHYSICIANS TO FIND OUT THE EXACT LOCATION OF THE INFECTED AREA,
ONCE THE RECONSTRUCTION PROCESS IS GETTING OVER IN THE
SCANNING DEVICE THEN THE IMAGES VIEWING IN THREE DIMENSION
VIEWS BUT SOME OF THE OLD GENERATION SCANNING DEVICE DOESN'T
HAVE ANY SEPARATE SOFTWARE FOR RECONSTRUCTING SO THE
PHYSICIANS ARE NED TO CAPTURE THE SLICING OF IMAGES AND THEN
RECONSTRUCTED USING SOME NEW SEPARATE SOFTWARE SUCH AS
MIMIC SOFTWARE WHICH HAS A PROGRAM FOR IMAGE
RECONSTRUCTION.
BIOMEDICAL ENGINEERING

13. The reconstructed images are allowed to copying in the memory
card or pen drive then the images are been loaded in the printer
from CD or pen drive. The bio-printer individually has some of the
materials like Polylactic acid, polyamide, glass filled polyamide,
stereolithography materials, silver, titanium and more biomaterials
are considered as biomaterials and it is very comfortable to create
the mechanical and biological model.

14. REPLACING HUMAN ORGAN
MODEL
ONCE THE MODEL IS GETTING READY THEN THE
PROTOTYPE IS ANALYZED BY THE SURGEON AND
THEN IT IS TREATED WITH SOME CELL CULTURE OR
GIVING PRACTICE ACCORDING TO THE FUNCTION OF
THE REPLACING ORGAN, THEN IT IS FULLY READY
FOR IMPLANTING THE TISSUE OR ORGAN
SUCCESSFULLY.

15. BENEFITS BEHIND BIO-PRINTING
The greater benefits of bio-printing is to give a greater advantage to the doctor to
note many things on the prototype, This bio-printing is very easily accessible, faster
production of reconstructed image model will take just an hour’s with excellent
quality of various unlimited shapes and geometry, on the other hand, difficult ideas
and designs with conservative manufacturing methods can take more that one day,
if not more than a number of weeks, this bio-printer can implement assorted
biomaterials with less waste production and also a very less risk production.
