Pharmaceutical printing is the process of producing medicines and medical products. There are several methods available to produce pharmaceutical printing, including Ink-Jet, Extrusion-based methods and binder jetting. All of these methods are viable, but each method has its own advantages and disadvantages. For example, Ink-Jet printers are more expensive and can be difficult to use. Binder jetting, on the other hand, is the least expensive method and can be used to print a wide variety of different materials.
Ink-Jet Printing
Ink-jet printing is an extremely important application in the pharmaceutical industry. It offers many advantages over conventional liquid deposition approaches. The main advantage of ink-jet printing is its versatility. It can process structures directly from CAD information. This makes it possible to create complex logos and full colour swatches.
Other benefits of ink-jet printing include its rapid processing rates and low processing costs. These are particularly important in the pharma industry, where regulatory codes and legibility are crucial. Ink-jet printing also allows for customisation of the dosage regime for each patient. Moreover, the print quality can be high.
Aside from being versatile, ink-jet printing can be used to print machine-readable codes. This can help manufacturers deter counterfeiting. A third benefit of ink-jet printing is that it can reduce the number of manufacturing steps. This makes it ideal for printing biologics, nanoparticles, and hazard labels. Despite these benefits, ink-jet printing is not suitable for all pharma printing applications.
Extrusion-Based Methods
Extrusion-based methods for pharmaceutical printing can be used to create oral dosage forms. They provide a rapid, low-cost method for developing the production process. In addition, they allow for the customization of the infill structure.
Printing enables the development of new and personalized oral dosage forms. It also enhances patient convenience and medication compliance. For this reason, the pharmaceutical industry is looking into various 3D printing techniques. These techniques include powder bed, material jetting, inject printing and extrusion-based methods. The different technologies are dependent on the type of substance to be printed.
Extrusion-based techniques are promising. However, they require a thorough understanding of the printing process and the resulting raw materials. There are several types of polymeric filaments available for commercial use. These include nylon, ABS and high impact polystyrene.
When designing the infill structure, it is important to consider the porosity and shape of the final product. Tablets are usually divided into four parts: the core, the shell, the outer and the inner layers.
Challenges with Binder Jetting 3d Printers
Binder jet 3D printing is a technique that allows the fabrication of orodispersible solid dosage forms. It uses selective binder droplets that bind powder particles. This technology is used to produce fast dissolving tablets as well as other pharmaceutical excipients.
The binder jet process is similar to the wet granulation procedure. The difference is that the powder material is sinterd at high localized temperatures to ensure that the structure is strong enough to support the desired mechanical strength. In addition, binder jet technology is suited to sinter microchannels and overhang structures.
GE Additive has been using this technology for five years. It is also one of the few companies to offer a binder jet based additive manufacturing system. Having a binder jet based system allows a company to differentiate itself from the other, high profile 3D printing OEMs.
There are some technical challenges that are still holding back the widespread adoption of these technologies. For instance, there has not been a lot of research on the clinical benefits of this technology. However, a multi-disciplinary approach to improving adoption could pave the way for human studies.
Formulation Change Needed For Pharmaceutical Printing
Inkjet printing has gained wide acceptance in the pharmaceutical industry, thanks to its versatility and ease of use. It allows deposits of drug solution in various concentrations and colours. Also, it can be used to produce complex logos and machine-readable codes.
Pharmaceutical printing requires the highest quality. A number of factors are involved, including regulatory codes, legibility, contrast, and viscosity. Using the latest technology, the process can be tailored to the individual patient's needs. This will ensure that the medications are safe, accurate, and affordable.
Tablets and capsules are two dosage forms that need to be formulated properly. For instance, a single capsule is administered to an individual patient, whereas a tablet can be split into multiple parts. Both of these factors affect the dissolution rate, appearance, and stability. One of the key considerations is the optimum temperature. It is important to print at a temperature above the melting point of the components.
