Pharmaceutical businesses are hesitant to implement 3D printing since there is currently no clear guidelines on the safety, efficacy, and quality of 3D printed pharmaceuticals. In order to guarantee the safety and effectiveness of 3D printed tablets, the industry needs to collaborate with recognised regulatory organisations to set up norms and criteria for their manufacture.

The difficulty of scaling up

The sector also must contend with the difficulty of scaling up 3D printing technology due to its high initial cost. It's not cheap to print with a 3D printer, and the raw materials themselves can be pricey. Smaller pharmaceutical companies may lack the capital necessary to invest in 3D printing technology, making this a substantial barrier to entry.

Manufacturing issues

When compared to conventional manufacturing techniques, the pace at which 3D prints are produced might be a hindrance to the technology's scalability. Another barrier to widespread use of 3D printing in the pharmaceutical business is ensuring product quality. Tablets can be manufactured in 3D, but constant precision and accuracy in the prints is challenging to obtain. It might be difficult to maintain sufficient quality control during mass manufacturing when printing tablets to ensure that they all match the required standards.

Difficulties of Intellectual Property

The difficulties of IP in 3D printing are another difficulty. Concerns about counterfeiting and Intellectual rights violation are heightened by the simplicity of replicating and manufacturing 3D printed medications. To keep fake medicines out of circulation and protect intellectual property, the industry needs to implement secure and reliable methods.
