Welcome to the 3D Printers page
3D printing is any of various processes in which material is joined or solidified under computer control to create a three-dimensional object, with material being added together (such as liquid molecules or powder grains being fused together). 3D printing is used in both rapid prototyping and additive manufacturing. Objects can be of almost any shape or geometry and typically are produced using digital model data from a 3D model. There are many different technologies, used in the 3D printing process. The most common by number of users being fused deposit modeling (FDM). Thus, unlike material removed from a stock in the conventional machining process, 3D printing or Additive Manufacturing builds a three-dimensional object from a computer-aided design (CAD) model, usually by successively adding material layer by layer.
Common choices in this style use x,y, and z axis orientation to produce a 3d print. There is a variant also known as a “Delta” style of printer that has 3 arms connected to a hotend.
UV Resin Style Printers
Stereolithography (SLA or SL; also known as stereolithography apparatus, optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photopolymerization, a process by which light causes chains of molecules to link, forming polymers. Those polymers then make up the body of a three-dimensional solid. Research in the area had been conducted during the 1970s, but the term was coined by Chuck Hull in 1984 when he applied for a patent on the process, which was granted in 1986.
Large Format Printers
One of the shortcomings of 3d printing has always been that the build area is too small to print anything useful. With the newer large format printers, entire pieces can be printed as opposed to smaller parts needing assembly, thus saving time and production costs.
The time to print useful things, such as aerospace and finely engineered automobile parts can be cut down considerably as many of the parts are printed as a solid piece. This contributes to a much stronger part than traditional welding, as well as the ability to make changes in production much faster with simple software tweaks.
With a larger build area, the parts can be produced soon such as entire fenders, hoods, doors, etc for automobiles. Centralized production means the parts can be produced only as they are needed, as opposed to warehousing large amounts of stock.
