About us 19.05

PrintyMed is a revolutionary medicine company that focuses on the development of artificial spider silk for different medical applications. Despite the well-known applications of artificial spider silk, our team of scientists, engineers and medical professionals are working together to create material that can be used to create 3D printed living tissue. This unique approach to medicine has the potential to revolutionize the medical field and improve the lives of millions of people. We are excited to be at the forefront of this new technology and are constantly pushing the boundaries of what is possible.

About Us
Innovative high-performance biotech material

PrintyMed has developed an innovative high-performance biotech material - artificial spider silk, that is environmentally friendly, fully recycled, 100% biodegradable, biocompatible and extremely versatile thanks to its extraordinary mechanical and biochemical properties.

Enhancing bio­compatibility of organ transplants and medical devices

The PrintyMed artificial spider silk is mechanically stable, biocompatible, safe for the human body, with high surface-to-volume ratio, and low immunogenicity.

Unique medical and functional properties

The PrintyMed artificial spider silk is mechanically stable, biocompatible, safe for the human body, with high surface-to-volume ratio, low immunogenicity. It provides physical functionality only – our products have no pharmacological effect

PrintyMed scientists have developed a unique method for producing chemically modified artificial spider silk by bioconjugation. The method mimics the native process of spider silk formation and yields artificial fibers that reproduce to a large extent the properties of natural spider silk. A great advantage of the method is the possibility of tailoring the material properties and introducing new functionalities enabled by the chemical modification of designed spider silk proteins. Further research is being carried out to adapt the method to 3D printing technology.

Material advantages:


  • Mechanically stable

  • Biocompatible

  • Safe for the human body

  • High surface-to-volume ratio

  • Low immunogenicity



  • Cosmetics

  • Coatings for medical devices

  • Drug delivery systems

  • Tissue regeneration

  • Bioprinting

Technology 19.05
Artificial spider silk for bioprinting

Spider silk is considered one of the most promising scaffolding materials as it is biocompatible, biodegradable, and has extraordinary mechanical propertiess.

Cells in human tissues reside in a solid matrix called the extracellular matrix (ECM), which can have a variable tissue-specific composition. The ECM provides structural support for cells to attach to and grow in three dimensions.

It also gives the tissues certain mechanical properties such as strength and elasticity that ensure their specific functions (e.g. stretching of muscles, skin resilience), and provides a degradable environment necessary for tissue remodeling (e.g. during wound healing). Because of the complexity of the ECM, in tissue engineering, it is replaced by different biomaterial scaffolds, which mimic the biological and mechanical functions of native ECM.
