3D Printing Layer Drying Control for Precision

The patent applies preliminary action by drying each fluid material layer before laminating the next layer. The drying process removes solvent from the previously deposited layer, causing it to solidify and gain mechanical strength. This preliminary solidification prevents horizontal spreading when subsequent layers are added, thereby maintaining manufacturing precision while enabling continuous lamination for high productivity.

The patent implements periodic action through alternating deposition and drying cycles. Each layer undergoes a periodic sequence of: (1) deposition of fluid material containing solvent, (2) drying to remove solvent and solidify the layer, (3) lamination of the next layer. This periodic alternation between wet deposition and dry solidification maintains layer stability while enabling continuous manufacturing.

The patent applies partial action by drying each layer to sufficient solidity for supporting the next layer, rather than requiring complete solvent removal. The drying process continues until the layer achieves adequate mechanical strength to prevent deformation under subsequent layers, which is sufficient for maintaining manufacturing precision without the need for exhaustive drying that would waste time.

The patent ensures continuity of useful action by overlapping the drying process with the preparation and deposition of the next layer. While one layer is drying, the system can prepare the next layer material and position the deposition head, so that drying never completely stops the manufacturing process. This continuous workflow minimizes idle time while ensuring each layer is sufficiently dried.

The patent applies preliminary action by implementing a standardized drying process for each layer that achieves sufficient solidity before the next layer is deposited. This preliminary drying ensures that each layer is prepared in advance with adequate strength to support subsequent layers, preventing deformation and maintaining precision without requiring extended overall drying time that would reduce productivity.

The patent utilizes parameter changes in the drying process, specifically controlling temperature and time parameters to achieve optimal drying efficiency. By adjusting these parameters, the system achieves sufficient layer solidity in minimal time, balancing manufacturing precision requirements with productivity maintenance.
