Abstract
An electrostatic-based layer-wise manufacturing system (e.g., 200; 200-1; 250; 282; 300) decouples a layer imaging process from a layer transfusion process. The layer imaging process is performed in a first batch process that is independent from the layer transfusion process that is performed in a second batch process.
Claims14
An electrostatic-based layer-wise manufacturing method for printing a three-dimensional part, the method comprising:
- using an imaging system to perform a layer imaging batch process to develop a plurality of layers of powder material and to transfer the plurality of developed layers onto a plurality of sheets;
- transporting the plurality of sheets to a transfusion system;
- and
- using the transfusion system to perform a layer transfusion batch process to transfuse the developed layers from the plurality of sheets onto a part to build the part.
