If we mention the processing 3d molding manufacturing industry in recent years, 3D printing out, rapid manufacturing, intelligent production and manufacturing these are all a few buzz words. This moniker, as if a hurricane, as if overnight in the academic, political, media, financial, manufacturing sector scraped a huge wave. But how much do people know about this idea? If you do not understand too much, here is an article, can be a comprehensive, detailed analysis of this noun, so that we really understand and master "what is called 3D printing", "what is called additive manufacturing".

Analysis I: Definition

Rapid Prototyping (RapidPrototyping, mobile mine commonly known as RP), introduced in the mid to late 80s of the 20th century, is a new type of technology based on the deposition of raw materials method, is felt to be a major breakthrough in the manufacturing industry in the last 20 years. It integrates mechanical automation, CAD, reverse engineering technology, hierarchical production technology, CNC processing technology, management science, and laser equipment, and can fully automate, immediately, quickly, and precisely change the design concept into a prototype with a certain role or immediately produce parts, thus giving an efficient and cost-saving way to complete the field of prototyping parts and testing new design ideas. The way At this stage, the Chinese media industry habitually calls rapid prototyping technology "3D printing out" or "three-dimensional printing", which looks more vivid image, but in fact, "3D printing out" or "three-dimensional printing" is the most popular term. However, in fact, "3D printing out" or "3D printing" is only a branch of rapid prototyping technology, which only means part of the rapid prototyping technology processing process.

Rapid Manufacturing (RapidManufacturing,mtr hk commonly known as RM), there is a small range and theoretical, small range is based on the laser powder calcination rapid prototyping technology of the new upgraded manufacturing core concept, in fact, belongs to the RP rapid prototyping technology in one of the branches, it means from the electronic data immediately and fully automated to achieve faster, soft and has a lower cost of production. It refers to a faster, softer and less costly production method that is immediately and fully automated from electronic data. In contrast to general rapid prototyping technology, additive manufacturing depends on the ability to produce the final product at the same time, and can be integrated into the production of bulk products to the production of large quantities of differentiated products; in theory, RM rapid manufacturing can include "rapid mold" technology and CNC numerical control technology, and thus can be comparable to RP rapid prototyping technology. Theoretically, RM rapid manufacturing can include "rapid mold" technology and CNC numerical control technology, so it can be comparable to RP rapid molding technology.

In 2009, ASTM created the F42 Committee, which defined AM as. "Processofjoiningmat-erialstomakeobjectsfrom3dmodeldata,usua-llylayeruponlayer, asopposedtosubtractivemanufacturingmethodologies." i.e.: a way of production and processing that is very different from the traditional good place of raw materials, based on upgrading raw materials, based on 3D CAD solid model data information, usually choose the level-by-level production and manufacturing methods, immediate production The production method of manufacturing a 3D physical digital model that is completely consistent with the corresponding mathematical analysis model.
