Relevance Of Reverse Engineering And Rapid Prototyping The relationship between reverse engineering and rapid prototyping Reverse engineering and rapid prototyping technology are important components of modern manufacturing technology. When two unit technologies are integrated into one product for rapid development, an optimal integration technology model is obtained. (1) The integration of reverse engineering and rapid…
Various Rapid Prototyping Techniques According to modern molding theory, the way objects are shaped can be divided into the following categories: (1) Removal molding: A method in which a part of materials is separated from the substrate in an orderly manner by a separation method. Traditional car, milling, planing, grinding, drilling, electric sparking and laser…
Fused Deposition Molding (FDM) Process The fused deposition manufacturing (FDM) process was successfully developed by American scholar Scott Crump in 1988. The materials of FDM are generally thermoplastic materials such as wax, ABS, nylon, and the like. Feed in the form of a filament. The material is heated and melted in the spray head. The…
Reverse Engineering And Rapid Prototyping Reverse engineering is a description of the product design process. Compared with the current forward engineering, the forward engineering is that we design the drawings first, then process the finished products according to the drawings, and the reverse engineering is the existing ones. The object is restored to a computer…
Advantages And Disadvantages Of The Melt Deposition Molding (FDM) Process Advantage (1) Due to the simple construction principle and operation of the hot melt extrusion head system, the maintenance cost is low and the system is safe to operate. (2) The molding speed is fast. The product produced by the fused deposition method does not…
Selective Laser Powder Sintering (SLS) Process The SLS process is called selective laser sintering and was developed in 1989 by C.R. Dechard of the University of Texas at Austin. The SLS process is formed from a powdered material. The principle is to spread the material powder on the upper surface of the formed part and…
SLS Process Characteristics The SLS process is characterized by a wide range of materials, not only for the manufacture of plastic parts, but also for the manufacture of ceramic, wax and other materials, in particular for the production of metal parts. This makes the SLS process attractive. The SLS process does not require support because…
3D Printing (3DP) Process The three-dimensional printing process was developed by the Massachusetts Institute of Technology E-manual Sachs et al. It has been commercialized by Soligen Corporation of the United States under the name of DSPC (DirectShell Production Casting) to manufacture ceramic shells and cores for casting. The 3DP process is similar to the SLS…
Light Curing (SLA) Technology SLA technology works on the principle of photopolymerization of liquid photosensitive resins. The liquid material can rapidly undergo photopolymerization under the irradiation of ultraviolet light of a certain wavelength and intensity, and the molecular weight sharply increases, and the material changes from a liquid state to a solid state. The laser…
Advantages And Disadvantages Of Light Curing (SLA) Technology The SLA method is currently the most studied method in the field of rapid prototyping technology and the most mature method in technology. The parts formed by the SLA process have high precision, the processing precision can generally reach 0.1mm, and the raw material utilization rate is…
