Ceramics have been considered unsuitable materials for Additive Manufacturing due to the low
ductility, the high brittleness of material, and the shrinkage of green body during post-processing.
However, with the gradual success of technical efforts to overcome the limitations of ceramic raw
materials, ceramic additive manufacturing technology is being highlighted as a more feasible
alternative AM technology especially in the fields of medical/bio, construction, aviation/ aerospace,
defense, energy, and consumer goods. This change is being considered due to the reduction of AM
production cost, the increase of freedom of design, and the realization of the diverse needs of
customers. This standard is for the characterization of photocurable ceramic slurries, which are
feedstock materials used for vat photopolymerization. The purpose of this standard is to clarify the
ambiguity between consumers and manufacturers by providing reliable and effective test methods
which are applied to characterize photocurable ceramic slurries. Standardization on characterization of
ceramic raw materials affects other fields which are directly related to ceramic additives, equipment,
parts, and final products. As a result, this standardization can contribute to the development of
standards in the whole area of ceramic AM.
The title and scope are in draft form and are under development within this ASTM Committee.
