Schematic diagram of a continuous inkjet printing process The continuous inkjet (CIJ) method is used commercially for marking and coding of products and packages. In 1867, Lord Kelvin patented the syphon recorder , which recorded telegraph signals as a continuous trace on paper using an ink jet nozzle deflected by a magnetic coil.
A continuous ink system ( CIS ), also known as a continuous ink supply system ( CISS ), a continuous flow system ( CFS ), an automatic ink refill system ( AIRS ), a bulk feed ink system ( BFIS ), or an off-axis ink delivery system ( OIDS) is a method for delivering a large volume of liquid ink to a comparatively small inkjet printhead.
The process of printing of low-melting point metals is called "direct melt printing" and was introduced in 1971 by Johannes F Gottwald patent, US3596285, "Liquid Metal Recording" with a Continuous inkjet (CIJ) long before any form of 3D Printing was ever considered.
3D printing processes. Computer-Aided Design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
Offset printing is a common printing technique in which the inked image is transferred (or "offset") from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water , the offset technique employs a flat ( planographic ) image carrier.
A line printer prints one entire line of text before advancing to another line. [1] Most early line printers were impact printers . Line printers are mostly associated with unit record equipment and the early days of digital computing, but the technology is still in use. Print speeds of 600 lines per minute [2] (approximately 10 pages per ...
An inkjet print head moves across a bed of powder, selectively depositing a liquid binding material. A thin layer of powder is spread across the completed section and the process is repeated with each layer adhering to the last. When the model is complete, unbound powder is automatically and/or manually removed in a process called "de-powdering ...
Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. [ 1] The drum then selectively collects electrically charged ...
