This technique is commonly referred to as optical manufacturing, light curing, or solid imaging. This form of 3D printing is almost the most scientific. If you ask me, the fi channel is unheard; This is serious. Let me elaborate on the process. Like all forms of 3D printing, engineers or 3D artists have to do some design work on the computer. This 3d printing form is different from other forms because the machine itself has a CAM system or a computer-aided manufacturing system. This means that the computer on the machine will automate the entire assembly process of the part, in addition to pulling the part out of the machine. Let\'s go into the actual process. After the computer image is sent to the machine, it will start manufacturing the product. In all SLA machines, there is an envelope or container for liquid-cured photopolymer resin. Imagine a small bucket in a large machine filled with liquid resin. When the printer starts and starts to work, it will start firing a subwoofer beam into the trash can of a liquid photosensitive polymer. The cured resin has been carefully designed, so it is very sensitive to ultraviolet rays. What does this mean? When UV rays are applied to a liquid photo polymer, the liquid becomes solid. Depending on the position of the beam, the liquid will solidify. For each layer in this resin bin, the beam will only hit the selected quantity determined by the initial computer image. This means that there will be excess liquids being recycled into the machine, unless the engineer who designed the product designed a block equal to the exact size of the binbin GmbH I mentioned earlier. Therefore, the process of SLA 3D printing is essentially cured liquid resin layer by layer from the UV beam, which is directly focused on the concise point in the box determined by the computer image. Think about it, a bunch of purple light is very focused on specific areas of the resin to create products with very high resolution. A bunch of UV light is focused well enough to create a curing resin prototype. I think this is great! SLA 3D printing is known for its low material cost. Compared with other forms of 3d printing, the build time of SLA3D printing is also very fast. It is selective for which part of each layer is assembled, similar to DMLS or SLS 3D printing, but at the same time, SLA printing is of its own type, because it makes products based on curing resin and ultraviolet rays. In my opinion, this is crazy. As I said before, the resolution of these parts is also very good, which means that the programming of this UV laser is very good. I was surprised by the technology.
