Buy the Best Resin 3D Printers
Resin 3D printers produce incredibly accurate prints, offer a wide variety of materials, and can produce parts relatively quickly. These precision machines used to cost tens of thousands of dollars, but in recent years desktop resin 3D printers have become ridiculously cheap and giving high-quality results.
Although SLA and DLP technology is extremely similar in principle, there are slight differences that separate the two.
SLA 3D Printing: SLA 3D printing utilizes two motors known as galvanometers. These motors, placed on the X and Y axis, work together to rapidly angle a pair of mirrors to aim a laser beam across the print area, solidifying resin into a 3D model. The layers of the model are broken down into a series of points and lines, which the galvos use to direct the laser beam.
DLP Technology: On the other hand, DLP technology uses a digital projector screen to flash a single image of each layer across the entire platform at once. Each layer of the 3D model is displayed as square pixels, meaning that the print is comprised of voxels. Flashforge Hunter is using DLP Technology.
LCD 3D Printing: As for LCD 3D printing, the process is nearly identical to DLP in that it utilizes projected light to solidify resin layer-by-layer until a 3D model is built. The main difference is that LCD 3D printers use a bank of UV LEDs to project light through a mask of the layer on an LCD panel. In contrast, DLP 3D printers utilize an array of micro-mirrors (each mirror corresponding to a pixel) to either project light, or not, thus creating a mask. Itech 3D Printers uses the LCD technology.
