Embodiment Construction

[0029] The present invention generally relates to a rapid prototyping system for manufacturing dental devices such as, for example, artificial teeth, dentures, splints, veneers, inlays, onlays, copings, framework patterns, crowns and bridges , models, orthotics, etc. More specifically, such dental devices can be fabricated using a support material that can be sculpted by ablation to build the dental device from a novel liquid into a three-dimensional object. The support material can be printed by LIFT (Laser Induced Forward Transfer), SLA (Stereolithography), DLP (Digital Light Processing), inkjet or mechanical systems, and undesired parts can be removed by laser beam and each layer can be sequentially shape to form. Support materials can be phased or cured prior to ablation and can be removed with water or other environmentally friendly solvents after the model is complete.

[0030] In an embodiment of the invention, an ablation-based 3D printer is used to create material s...

Abstract

A three-dimensional dental device is fabricated in a layer-by-layer approach using a support material. The support material is deposited in a liquid form on a surface, hardened by cooling or ultraviolet (UV) curing, and selectively ablated to create an area within which the desired structure of the dental device will be formed. Active dental material is deposited into this area, and the layer-by-layer process repeated until the three-dimensional dental device has been completed. Thereafter, any remaining support material is removed by water or other solvent.

Description

[0001] related application [0002] This application claims priority to US Provisional Application 62 / 807,382, filed February 19, 2019, and US Provisional Application 62 / 823,079, filed March 25, 2019. technical field [0003] The present invention relates to printable material systems, such as systems configured for the manufacture of dental products such as artificial teeth, dentures, splints, veneers, inlays, onlays, copings, framework patterns, crowns and Bridges, casts, aligners and more. Background technique [0004] Conventional manufacturing methods for making parts are based on layer-by-layer techniques. In this technique, a fabricated part is viewed as a series of discrete cross-sectional regions that when brought together form a three-dimensional ("3D") structure. Building parts layer by layer is very different from conventional machining techniques of cutting and drilling metal or plastic parts into the desired shape. [0005] In rapid prototyping techniques, p...
