Like other powder-bed processes, surface finish and accuracy, object density, and—depending on the material and process—part strength may be inferior to technologies such as stereolithography (SLA) or selective laser sintering (SLS). Although "stair-stepping" and asymmetrical dimensional properties are features of 3D printing as most other ...
For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.
The next development releases added connection interfaces. In 1992, a card with both 8P8C modular telephone and BNC connectors for Ethernet was released, and in 1993, the first external JetDirects were introduced with a parallel interface. This enabled JetDirect cards to connect to almost any printer, making that printer network-capable.
In 3D computer graphics, a wire-frame model (also spelled wireframe model) is a visual representation of a three-dimensional (3D) physical object. It is based on a polygon mesh or a volumetric mesh, created by specifying each edge of the physical object where two mathematically continuous smooth surfaces meet, or by connecting an object's constituent vertices using (straight) lines or curves.
Surface printing machine printing wallpaper. Surface printing is an automated printing method. It first used in 1839. Most wallpaper was originally printed on surface printing machines. Surface printing machines are structured similarly to a ferris wheel, with a large central roller over which the paper travels; the individual ink rollers ...
A Direct Cable Connection dialog box on Windows 95. Direct Cable Connection (DCC) is a feature of Microsoft Windows that allows a computer to transfer and share files (or connected printers) with another computer, via a connection using either the serial port, parallel port or the infrared port of each computer.
An IEEE 1284 36-pin female on a circuit board. In the 1970s, Centronics developed the now-familiar printer parallel port that soon became a de facto standard.Centronics had introduced the first successful low-cost seven-wire print head [citation needed], which used a series of solenoids to pull the individual metal pins to strike a ribbon and the paper.
SMEMA is an acronym for the Surface Mount Equipment Manufacturers Association. In 1999 they merged with the IPC to form the IPC SMEMA Council. [1] One standard they have is for the wiring of communications between Surface mount technology producing machinery such as a Stencil Printer or a Pick and Place Machine on an Electronics production line ...
