3D printing Flashcards
different ways sth can be manufactured
- subtractive
- formative
- additive
When did stereolithography start?
1983-1984
a few 3D printing milestones / impact on medical sector
- milled 3D models
- 1992: fused deposition printer
- 1995: selective laser melting
- CAD / virtual surgical planning
- 2015 printers for metals and polymers
- direct 3D manufacturing and medical applications
what are 4 key drivers of medical 3D printing? (advantages)
- improved accuracy
- improved predictability
- decreased surgical time
- less invasive surgical approaches
some key benefits of medical 3D printing
- personalized
- increased patient safety
- reduced time and complications
- improved patient consent
- better education and training
- surgical planning
give an overview of the different techniques (and which material they use)
1) fused deposition modeling = thermoplastics
2) SLA or digital light processing = photopolymers
3) selective laser sintering = ceramics
4) binder jetting
5) selective laser melting = metals
6) bioprinting
steps in digital workflow
- imaging (MRI, CT, …) + 3D scans
- segmentation
- virtual surgery
- slicing / export
- 3D printing
a few examples in CMF surgery
- customized titanium implant
- 3D navigation system
- orbital implant
- bio resorbable implants
applications for bioresorbable implants
- orbital reconstruction
- fronto orbital fixation plates
- alveolar ridge reconstruction
- wedge osteotomies for distal radius
- bone plates for fractures
for which patients in particular are resorbable implants very interesting?
children -> takes away the need for a second surgery as the kid grows
why does it help save time and money?
- reduced length of stay
- less complications
- less treatment costs
What would be a big next step for printing implants?
printing in house and directly implant -> faster and cheaper
