Alternative terms for this process include "additive construction." [1] [2] "3D Concrete" refers to concrete extrusion technologies whereas Autonomous Robotic Construction System (ARCS), large-scale additive manufacturing (LSAM), and freeform construction (FC) refer to other sub-groups. [3]
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.
Liquid additive manufacturing (LAM) is an additive manufacturing technique which deposits a liquid or highly viscous material (e.g. Liquid Silicone Rubber) onto a build surface to create an object, which is then vulcanised using heat to harden it. [55] [56] [57] The process was originally created by Adrian Bowyer and was then built upon by ...
Makers that have built open source granulators [17] or have access to other types of waste plastic shredders (e.g. from Precious Plastic [18]) can generate feedstock for hanging waste printers for under $1/kg, which makes large scale production with a hangprinter competitive with any conventional manufacturing process.
Binder jet 3D printing, known variously as "powder bed and inkjet" and "drop-on-powder" printing, is a rapid prototyping and additive manufacturing technology for making objects described by digital data such as a CAD file. Binder jetting is one of the seven categories of additive manufacturing processes according to ASTM and ISO. [1]
The ACTCM barges are also referred to MCA (Missile Cum Ammunition) barges, but all are designated as Large Scale Additive Manufacturing (LSAM). [7] All major and auxiliary equipment/systems on the barge, which is set to have a service life of 30 years have been sourced from indigenous manufacturers. [8]
