If you are in the pharmaceutical industry, you may have heard the term "pharmaceutical printing". This term is used to describe the process of printing a product from a 3D model. There are a number of methods to do this. Some are extrusion based, while others are embedded. It is important to understand the differences between each method, as well as the advantages and disadvantages.
Extrusion-Based Methods
Three-dimensional printing is believed to be the most groundbreaking discovery ever made. It can be used to create dosage forms, tissue models, surgical models, and multi-drug devices. However, the pharmaceutical printing industry is still a long way from fully integrating this technique into drug therapy.
For this purpose, novel extrusion-based methods have been developed. These techniques are based on the principle of extrusion of thermoplastic rod-shaped materials. They can be employed to produce a wide variety of engineered tissues, including cell-laden tissues and cell-free tissues.
One of the most promising applications of 3D printing is to develop customized dosage forms for individual patients. These dosage forms can be designed to contain a specific drug, dosage form, and dose. This is especially important for orphan drugs for small groups of patients.
In addition to its therapeutic applications, 3D printing is also useful in drug formulation, as well as in the compounding of medicines for pharmacies. As in other industries, this process requires training and specialist expertise.
Non-Heated Extrusion 3d Printers
Non-heated extrusion 3D printers are used to create a variety of dosage forms. For instance, they can create immediate dosage forms, extended-release capsules, and gel-filled capsules. They can also be used to produce capsules with multiple compartments.
The FDA has acknowledged the potential of 3D printing to improve the safety and quality of medications. However, the agency has identified several issues that need to be addressed. One is the ability to accurately determine the release profile of drugs and to verify that the intended product characteristics have been printed successfully. In addition, pharmaceuticals may not be compatible with different printing processes.
Another major concern is the possibility of contamination when printing edible products. This can affect the strength, purity, and uniformity of a drug product. Therefore, the parts of the printer should be made from materials that are safe. It is also important to develop standard operating procedures for cleaning the printer and its internal components.
Embedded 3d Printers
Embedded 3D printers are an innovative strategy for customized medication preparation. It allows pharmacists to print custom dosage forms that can be adapted to fit the needs of the patient. Depending on the desired characteristics of the printed medication, it can also enhance safety and efficiency.
An ideal 3D printer for a pharmacy setting should be affordable and easy to operate. It should also be able to use approved pharmaceutical ingredients efficiently. Moreover, it should be able to print a wide variety of medications.
However, most of the 3D printing technologies available on the market are not yet suitable for routine pharmacy operations. Some printers are too small or too expensive, while others are only offered as industrial-size models. Furthermore, different printers have differing levels of accuracy, which can also impact the accuracy of the drug products they produce.
Some of the most common dosage forms produced include tablets, capsules, and implants. Each of these can be produced in various geometries. Additionally, they can be divided into two or four parts. This flexibility of the formulation can result in over- or underdoing.
