Composition for three dimensional printing |
摘要 |
A layer of particulate material (20) is applied on a downwardly movable surface (22) of a container (24), preferably using a counter-roller to minimize disruption of previously formed layers. The layer thickness is preferably 50-75 micrometers and an ink-jet nozzle (28) delivers droplets of an aqueous fluid (26) to a portion (30) of the material in any predetermined two-dimensional pattern, causing a reaction and re-hydration of the plaster. A solid circular layer is formed that becomes a cross-sectional portion of the final article, formed of the assembled portions. An independent claim is included for a method for forming an article. |
