Principle of 3d printing-Selective laser sintering(SLS)

Selective laser sintering (SLS) is an additive manufacturing (AM) technique. Selective laser sintering uses a laser as the power source. The machine automatically aims the power source at points in space defined by the 3D model. The laser will sinter the powdered material, and bind  the material together to create a solid structure. There are several technologies that we can use for low-volume …

Principle of 3d printing-Fused Deposition Modeling(FDM)

FDM (Fused deposition modeling), or FFF(Fused Filament Fabrication), is the most widely used 3D Printing technology. Most installed 3D printers are FDM printers. It is often the first technology people are exposed to. For desktop or consumer 3d printers, FDM printer is the most popular in the world now. So if you want to get into 3d …

Principle of 3d printing-Stereolithography(SLA)

Stereolithography(SLA) is an additive manufacturing process. It is a 3d printing technology. An ultraviolet (UV) laser will focus on a vat of photopolymer resin. With the help of computer aided manufacturing or computer-aided design (CAM/CAD) software, the UV laser will draw a pre-programmed design or shape on to the surface of the photopolymer vat. Photopolymers are sensitive to ultraviolet light, …

3D print colorful part

Additive manufacturing (AM), usually we call it 3d printing, uses computer-aided design to build objects layer by layer. It becomes more and more popular. There are several types of 3d printing technology that 3d printer use today: FDM,SLA,DLP,SLS,MJ,DOD,BJ,DMLS,etc. 1. FDMFused Deposition Modeling-FDM It is the most popular 3d printing technology. Material: Thermoplastic filament(PLA,ABS,PET,TPU,PETG,Nylon,wood) Dimensional Accuracy: …
