Conclusion

Sterilization of medical objects to be used in a clinical setting may lead to deformation of the printed model if not used in proper sterilization protocol according to the material glass transition temperature (Tg) especially for heat and pressure sterilization.

Formaldehyde presents to be the most suitable sterilization method for thermoplastic polymers and photopolymer resins.

Regulations and protocols must be defined and followed to assess correct application of 3DP/AM technologies in healthcare.
