3D printing technology is a general term for a series of rapid prototyping technologies whose basic principle is stack manufacturing. The rapid prototyping machine forms the cross-sectional shape of the workpiece by scanning in the XY plane, while the discontinuity in plane Z displacement , Eventually forming three-dimensional parts. The rapid prototyping technology on the market is divided into 3DP technology, FDM melt laminating molding technology, SLA stereolithography, SLS laser sintering, DLP laser forming technology and UV UV forming technology.
3DP Rapid Prototyping Technology: 3D printers using 3DP technology use standard inkjet printing technology to create 3D solid models by layer-by-layer creation of individual components by laying liquid-bonded bodies on a thin layer of powder and printing cross-sectional data, With this technology, the printed sample model has the same color as the actual product. The color analysis result can be directly depicted on the model. The information conveyed by the model sample is larger. We only need to know the SLS laser sintering technology.
SLS constituency laser sintering technology: SLS laser sintering technology is selected by pre-worktop with a layer of powder material (metal powder or non-metallic powder), and then let the laser under the computer control in accordance with the interface profile information on the solid part of the powder sintering, Then continue to cycle, layers of accumulation molding. The method has the advantages of simple manufacturing process, wide material selection range, lower cost and fast forming speed, and is mainly used for directly manufacturing the rapid die in the foundry industry.
DLP Laser Rapid Prototyping Technology: DLP laser prototyping is similar to SLA stereolithography except that it uses a high-resolution digital light processor (DLP) projector to cure the liquid photopolymer and photo-cure it layer by layer , The speed is faster than SLA stereolithography of the same type thanks to the slide-like flake curing on each layer. The technology provides high precision molding and is resistant to injection molded durable plastic parts in terms of material properties, detail and surface finish.
And my company's metal machine is used SLS laser sintering technology, the product according to their needs sintered materials, set their own parameters, without additional costs. Fully enclosed cleaning powder recovery system, the entire production process is no powder exposed to the air, no environmental pollution, to ensure the personal safety of operators, no risk of oxidation and explosion of materials.
