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…
Layered Solid Manufacturing (LOM) Process The LOM process is called laminated solid manufacturing or layered solid manufacturing, and was developed in 1986 by Michael Feygin of Helisys, USA. The LOM process uses sheet materials such as paper, plastic film, and the like. The surface of the sheet is previously coated with a layer of hot…
Rapid Prototyping Process First, the construction of the 3D model of the product Since the RP system is directly driven by the 3D CAD model, it is first necessary to construct a 3D CAD model of the workpiece being machined. The three-dimensional CAD model can be directly constructed by computer-aided design software (such as Pro/E,…
Important Features Of Rapid Prototyping Technology 1. Can make arbitrarily complex 3D geometric entities Thanks to the principle of discrete/stacking, it simplifies a very complex 3D manufacturing process into a superposition of 2D processes, enabling the machining of arbitrarily complex shaped parts. The more complex the part, the more it shows the superiority of RP…
Laser Curing Rapid Prototyping Materials Photosensitive resin is a substrate that is laser-cured and rapidly formed, and its performance characteristics have a decisive influence on the quality of the molded part. Photocuring resins using SL should generally have the following properties: (1) The viscosity is low, and the low-viscosity resin is favorable for the faster…
SLA Laser Rapid Prototyping The SLA process, also known as light modeling or stereolithography, 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…
