Large 3D printers have been developed for industrial, education, and demonstrative uses. A large delta-style 3D printer was built in 2014 by SeeMeCNC. The printer is capable of making an object with diameter of up to 4 feet (1.2 m) and up to 10 feet (3.0 m) in height.
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
As the material is generated layer by layer the tray is gradually lifted and the photo inhibitors will not allow adhesion near the window. [13] Rapid, large-volume, thermally controlled 3D printing, using a mobile liquid interface. Another way to address the adhesion problem is to create a dead layer which prohibits the curing process.
(Can be approximated as height of the part) Support structure optimization: Supported area varies as per orientation. In some orientations, it is possible to reduce support area. Easy peel-off: Reorienting such that the projected area of layers varies gradually makes it easier to peel off the cured layer during printing. Orientation also helps ...
The printer is available either assembled or as a kit. The build volume is 180 x 180 x 180 mm, and the print is performed on a spring steel sheet which meant to be easy to remove. [2] Minimum layer resolution is 50 micrometers, and the maximum travel speed is 200 millimeters per second.

Stereolithography (SLA or SL; also known as vat photopolymerisation, [1] 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 photochemical processes by which light causes chemical monomers and ...
3D concrete printing, or simply concrete printing, refers to digital fabrication processes for cementitious materials based on one of several different 3D printing technologies. 3D-printed concrete eliminates the need for formwork, reducing material waste and allowing for greater geometric freedom in complex structures. With recent developments ...
