Table 3.

Advantages and disadvantages of printing technologies used in tablet printing applications.

Printing Technology	Advantages	Disadvantages
FDM	High drug loading Can print complex shapes Easy to adjust drug release profiles	Preprinting processes can take time Possible thermal degradation of APIs
DIW	High drug loading No risk of thermal degradation	Possible phase separation of drug formulations Hard to uniformly distribute APIs within the paste Drying of the tablet is required post printing
SLS	High resolution No need for preprinting processes	Possible degradation of APIs due to sintering
SLA	High resolution	Possible degradation of APIs due to laser projected onto the drug-loaded solution Additional post-printing processes needed, such as photocuring of the final product
DLP	High resolution	Possible degradation of APIs due to laser projected onto the drug-loaded solution Additional post-printing processes needed, such as photocuring of the final product
Inkjet	Versatility of the technology, can be used with heat or light-based approach	Cannot be used with high drug loading APIs can be affected by high shear rates during printing
BJ	Uniform final product	Highly porous final products lead to low mechanical properties Requires additional post-printing processes such as sintering
