It can be divided into: LCD3D printers, such as the molding principle of Idim photocuring LCD3D printers, that is, some substances will harden when they see light, which is called "photocuring"; SLA3D printer, using the method that liquid photosensitive resin can quickly solidify into solid under ultraviolet irradiation; SLS3D printer, laser selective sintering molding, FDM3D printer, plastic line is melted and printed layer by layer. Expansion: Idim 3D printer has launched a completely independent and innovative product (Delta series) printer, which adopts single nozzle design, making printing more stable and the accuracy can reach 100 micron. Use environmentally friendly materials, such as PLA ABS and other consumables. Printed products have high precision and are environmentally friendly. Looking ahead, we will have more fully functional 3D printers. Idim is committed to building a digital ecosystem of 3D printing. Its business scope focuses on R&D, manufacturing and sales of 3D printers, and extends to 3D education course services, 3D network cloud platform services and 3D printing integrated services.
