Question 1

what is bioink preparation

Answer 1

bioink is living cells e.g collagen,
this allows cells to grow on the nutrient to survive,
the perp is based on function and patent

Question 2

what is bioprinting

Answer 2

manufacture process where bioink is combined and used to create tissue-like structures and imitate natural tissues in a layer by layer manner

Question 3

printing in bioprinting

Answer 3

0.5mm layer by layer is deposited.

delivery of deposition depend on number of nozzles and type of bioink used

Question 4

what is solidification in bioprinting

Answer 4

as deposition takes place the layers start off as liquid and begin to solidify (crosslinking )

Question 5

what is crosslinking

Answer 5

process of blending and solidification of bioink deposition,
aided by UV light, heat and chemicals

Question 6

diff between 3d printing and 3d bioprinting

Answer 6

3d bio- uses living cells suspension instead of plastic therefore you must maintain sterile printing conditions

Question 7

steps of bioprinting

Answer 7

1-pre bioprinting- digital model using CT and MRI scans
2-bioprinting -bioink prints layer by layer
3-post bioprinting- mechanical and chemical stimulation of parts to create a stable structure

Question 8

2 bioprinting method

Answer 8

3d imaging

3d modeling

Question 9

what is 3d imaging

Answer 9

digital model by ct and MRI scan
provides a perfect fit of tissues
no adjustment for the surgeon

Question 10

what is 3d modelling

Answer 10

blueprint generated using AutoCAD
includes layer by layer instructions
surgeon adjust modelc
