Photo-crosslinked acrylates offer the possibility of developing and supplying suitable materials which meet the requirements of additive manufacturing (AM) and which can be used as materials for medical application fulfilling the requirements of biocompatibility and long-term stability. Their mechanical properties can be adjusted in a wide range and they are suitable for applications ranging from dental fillings to contact lenses.
Synthetic biocompatible resins are a cost effective material class suitable for various AM technologies such as stereolithography (STL, SLA, MPP, TPP), 3D inkjet and extruder dispersion printing techniques.
At Fraunhofer new polymeric and hybrid photo-crosslinkable materials are developed that meet AM process-related boundary conditions, e.g keeping within viscosity limits, achieving three-dimensional UV crosslinking, and curing by visible laser light. The range of developed materials covers up soft elastic materials e.g. for development of artificial blood vessel equivalents to hard bone-like materials. Also (water) soluble or mechanical removable support-materials have been developed.
