Considering that the ageing of the population is not going to stop, the need for
biocompatible materials is continuously increasing, especially in the field of
bone substitutes as well as in the fabrication of surgery tools. The Optoform
process is an additive manufacturing technology able to shape most of the
common biocompatible ceramic materials such as hydroxyapatite (HA) and
tricalcium phosphate (TCP). Those ceramic materials are largely studied to
substitute bone defects or as voids fillers while stronger bioinert materials like
alumina and zirconia can find applications in surgery tools or in dentistry. The
Optoform process allows building a component, layer by layer, from CAD data,
leading to significant advantages: 1) the manufacturing of elements with a
complex geometry and with a controlled porosity that would be impossible to
demold or to machine; and 2) short delays of production for customized part
with the desired characteristics and design. The quality control of these parts
is essential for medical use and is certified by the control of each step of the
manufacturing process: synthesis of biocompatible ceramic powders, preparation
of photo-curable resin based paste, shaping of the part by Optoform and
subsequent thermal treatment for debinding and sintering.
