3D printing, a type of rapid 3D prototyping technology, is a technology that uses powdered metal or plastic and other bondable materials to construct objects based on digital model files through layer-by-layer printing. The materials used in 3d printing for SLS is nylon FS3300PA) solid powder, nylon + glass fiber (FS3400GF) solid powder processing accuracy: ±0.2mm /100mm, the largest overall molding size: 350*350*420mm.

Features of DLP SLA (Stereolithography) 3D Printing

Steel progressive dies are a precision tooling solution for high-volume production of stamped metal parts. Features include precise and efficient operation, the ability to perform multiple operations in one pass, and consistent quality and accuracy. Such tools are critical to industries such as automotive, electronics and appliances, enabling cost-effective mass production of complex precision parts.

FAQs of SLA (Stereolithography) 3D Printing

1 How does SLA 3D printing work?



SLA (dlp stereolithography) 3D printing works by using a process called photopolymerization to create three-dimensional objects layer by layer. Here's a simplified breakdown of the SLA 3D printing process:

1. Design: The 3D model of the object to be printed is created using computer-aided design (CAD) software.

2. Slicing: The 3D model is then sliced into thin layers, typically between 25-100 microns thick, which will be used as a guide for the printing process.

3. Printing: A vat of liquid resin, which is sensitive to ultraviolet (UV) light, is used as the printing material. A platform is lowered into the resin, and a UV laser is used to trace the first layer of the object onto the surface of the resin, causing the resin to solidify in the desired shape.

4. Layer-by-layer building: After the first layer is solidified, the platform is raised slightly, and the next layer is traced onto the resin. This process is repeated for each layer of the object, gradually building the 3D object from the bottom up.

5. Rinse and Cure: Once the printing is complete, the object is carefully removed from the resin and rinsed to remove any excess uncured resin. The object is then cured using UV light to ensure that all the resin is fully hardened and the object is ready for use.

2 What are the key advantages of SLA 3D printing?



The key advantages of SLA 3D printing include High Precision; a Wide Range of Materials; Rapid Prototyping; Fine Feature Detail; Smooth Surface Finish; High Resolution; and Support Structure.

3 What types of materials are compatible with SLA printing?



SLA printing is compatible with a variety of materials, especially photopolymer resins. These resins can be tailored to specific applications based on their characteristics, such as flexibility, durability, transparency, or resistance to temperature and chemicals. Some common types of resin materials used in SLA printing include standard resins, tough resins, flexible resins, high-temperature resins, castable resins for investment casting, and dental resins.
