Wash it and cure it so that it hardens . In addition, this type of resin has a strong odor and stains a lot, so it is necessary that the printers are located in a ventilated space. Let's see how it works: digital light procedure (dlp) among the main 3d printing technologies we find the digital light procedures (dlp). This technology was invented in 1987 by larry hornbeck of texas instrument and has much in common with stereolithography. Both systems use liquid photopolymers, that is, resins that harden when applying ultraviolet rays.
In the dlp system, the light is applied through a special projector that emits a mask of the entire solid part of the object in one layer and the E Commerce Photo Editing rest in black. On the contrary, in the sla system, light is projected through a laser, as we have seen in the previous video. Dlp printers are the ones that are bringing 3d resin printing closer to home use. They actually work with the same materials as sla printers, but they are easier to manufacture. 3d printers are currently being built under this dlp technology using light beams or even mobile screens to cure or harden the resin instead of the complex sla laser system. That is why right now there are many dlp printers on the market in the low-cost segment that anyone can buy.
Finally, indicate that this type of printers share the same advantages and disadvantages as sla printers. As for the main uses of this type of printers are jewelry, models, pieces for the dental sector, etc. Being the details the key point in this technology. In the following video you will be able to analyze the anycubic photon printer. A low cost dlp printer. Selective laser synthesis (sls) finally we will talk about sls technology that is similar to sla. The difference is that this printer uses the powder material instead of liquid resin. These types of printers use a laser to melt and bond the powder particles together to create a solid structure.
