Solid free-form techniques for making medical devices for controlled release of bioactive agent and implantation and growth of cells are described using computer aided design. Examples of SFF methods include stereo-lithography (SLA), selective laser sintering (SLS), ballistic particle manufacturing (BPM), fusion deposition modeling (FDM), and three dimensional printing (3DP). The macrostructure and porosity of the device can be manipulated by controlling printing parameters. Most importantly, these features can be designed and tailored using computer assisted design (CAD) for individual patients to optimize therapy.
Techniques de modélisation de solides à structure non imposée destinées à la fabrication par conception assistée par ordinateur de dispositifs à usage médical assurant la libération lente d'agents bioactifs et l'implantation et la croissance de cellules. Les techniques de ce type sont par exemple la stéréolithographie (SLA), le frittage sélectif par laser (SLS), la fabrication de particules balistiques (BPM), la modélisation par dépôt en fusion (FDM) et l'impression tridimensionnelle (3DP). On peut moduler la macrostructure et la porosité du dispositif par réglage des paramètres d'impression. On peut notamment élaborer et personnaliser ces caractéristiques par conception assistée par ordinateur (CAO), de manière à optimiser le traitement de chaque malade.
