| Dispenser printing |
-Stage needs to be moved based on the pattern |
Slow |
-Compatible for both organic and inorganic inks |
-Only prints on flat surface |
| -Mask free method |
-Larger particle size can block nozzle |
-Multiple run needed to print vertical structure |
| -Needs preussre or electric field for ink dispension |
-Small feature size can be achieved |
| Inkjet printing |
-Mask free method |
Slow |
-Compatible for both organic and inorganic inks |
-Only prints on flat surface |
| -Nozzle moves based on pattern |
-Larger particle size can block nozzle |
-Printing vertical structure not possible |
| -Non-contact printing, protects substrate from contamination or damage |
-Low viscosity low volatility |
-Small feature size can be achieved |
| Screen printing |
-Stencil or mesh needed as mask |
Moderate |
-Highly viscous ink needed |
-Can print on non-flat surface |
| -A squeegee type device is used to force ink through the mesh |
-No limitation about particle size |
-Can print thick film |
| -Small feature size cannot be achieved |
| Roll-to-roll printing |
-Stencil or mesh needed as mask |
Fast |
-Medium to highly viscous ink needed |
-Can print on flexible surface |
| -A rotary structure needed to move the substrate |
-No limitation about particle size |
-Printing layers on top of each other is difficult due to alignment issues |
| -Hard contact compression is used to transfer the ink to the substrate |
| Aerosol jet printing |
-Compressed air flow required |
Slow |
-Inks needs to be volatile |
Can print on non-flat substrate |
| -Non-contact printing, protects substrate from contamination or damage |
| -Larger nozzle size can tolerate larger ink particles |
| Brush painting |
-Stencil/mask needed |
Slow |
-High viscous ink needed |
-Can print on non-flat substrate |
| -Cheap method, brush needs to be moved manually ovar the stencil |
-Small feature size cannot be achieved |
| -Can print thick film |
