Abstract
Modeling material formulations usable in additive manufacturing of a denture structure, and additive manufacturing of denture structures employing same are provided. The modeling material formulations and the additive manufacturing parameters provide denture structures that exhibit mechanical, physical and biocompatibility properties that meet the requirements of the acceptable standards.
Claims20
A modeling material formulation usable in additive manufacturing of a denture structure, the modeling material formulation comprising:
- at least one multi-functional ethoxylated aromatic (meth)acrylate featuring at least 10 ethoxylated groups and/or Tg lower than 0° C. (Component D2), in a total amount of from 15 to 25% by weight, of the total weight of the formulation;
- at least one multi-functional urethane (meth)acrylate featuring Tg lower than 100° C. (Component G), in a total amount of from 15 to 25% by weight, of the total weight of the formulation;
- at least one mono-functional alicyclic (meth)acrylate (Component E2), in a total amount of at least 40, or at least 45, or of from 45 to 55, % by weight, of the total weight of the formulation;
- at least one mono-functional acrylate (Component E3), in a total amount of from 3 to 10, or from 5 to 10, or from 3 to 8, % by weight, of the total weight of the formulation;
- and
- at least one dispersant (Component H),
- the modeling material formulation further comprising a photoinitiator (Component J) and optionally further comprising a coloring agent (Component P).
