Product Specification

Kings High speed SLA 3d printer, making large size prototyping easier.

SLA 3D printer, also known as photo-curing 3D printer, or laser 3D printer. It is a 3D printing device that uses the principle of stereo light curing technology.

SLA is an abbreviation of "Stereo Lithography Apparatus", which is an abbreviated form of stereolithography. It is a very important process technology in the 3D printing technology molding process. The technology mainly uses a laser of specific intensity to focus on the surface of the photocurable material (the material is mainly photosensitive resin), which makes it point to line and line to surface. Finish the printing work on one layer, and then proceed to the next layer after the completion of one layer, and repeat the cycle until the final product is completed.

Technical principle

Focusing on the surface of the photocurable material with a laser of a specific wavelength and intensity, from point to line, from line to surface solidification, complete a level of drawing operation, then move the lifting table vertically in the height of a layer, and then solidify Another level. This layer stacking constitutes a three-dimensional entity.

SLA is the first practical rapid prototyping technology, using liquid photosensitive resin raw materials. The process is to first design a three-dimensional solid model through CAD, use a discrete program to slice the model, design the scan path, and the generated data will precisely control the motion of the laser scanner and the lifting platform; the laser beam is controlled by the numerical control device. The surface of the liquid photosensitive resin is irradiated according to the designed scanning path to cure a layer of resin in a specific area of ​​the surface. When a layer is processed, a section of the part is formed; then the lifting platform is lowered by a certain distance on the solidified layer. Covering another layer of liquid resin, and then performing a second layer scanning, the second solidified layer is firmly bonded to the previous solidified layer, so that the layers are superposed to form a three-dimensional workpiece prototype. After the prototype is taken out of the resin, the final curing is carried out, and then the desired product is obtained by polishing, electroplating, painting or coloring.

Application of technology

SLA technology was patented by Charles Hul in 1984. In 1988, 3D System of the United States launched the commercial prototype SLA-1, which is the world's first rapid prototyping machine. SLA various types of forming machines occupy a large share of the RP equipment market. It is mainly used to manufacture a variety of molds, models, etc.; it is also possible to replace the wax molds in investment casting by using SLA prototype molds by adding other ingredients in the raw materials. SLA technology has a faster forming speed and higher precision, but it will inevitably generate stress or cause deformation due to shrinkage during curing of the resin. Therefore, the development of photosensitive materials with small shrinkage, fast curing and high strength is the development trend.

Technical advantages

1. The technology is mature. The photocuring molding method is the earliest rapid prototyping process with high maturity and time-testing.

2. Fast speed. Prototype made directly from CAD digital models, processing speed is fast, product production cycle is short, no cutting tools and molds are needed.

3. Manufacture of complex structures. It can process prototypes and molds with complex structural shapes or difficult to shape using traditional methods.

4. Design changes are easy. Visualize CAD digital models and reduce the cost of bug fixes.

5. The design change cycle is short. Once the design problem is discovered, the design changes can be implemented very quickly, samples can be provided for the experiment, and the results of the computer simulation calculation can be verified and verified.
 

Product Description

KINGS SLA(Stereolithography) 3D PRINTER is an additive manufacturing machine that works by focusing ultraviolet laser onto a vat of photopolymer resin. With the help of CAM or CAD software, UV laser is used to draw a pre-programmed design or shape on surface of the photopolymer vat. Photo -polymers are sensitive to ultraviolet light, so the resin is photochemically solidified and forms a single layer of desired 3D object. This process is repeated for each layer of the design until completed.
