3D DLP Printer | Desktop DLP 3D Printer For Jewelry
Currently, one could find a range of 3D printing techniques on the market. However, each system is better suited to a specific task so choosing the right system for your work will help you set better expectations on the final output and decide what is best for your application. More often than not, a DLP printer is the best suited option for a 3D printing task.
Digital Light Processing 3D printing, more commonly known as DLP 3D Printing, is one of the most common methods of 3D resin printing. A 3D DLP printer is popular for a range of reasons and is used when there is a need for watertight, isotropic and highly accurate prototypes or for components with smooth finishes and fine surfaces.
What is a 3D DLP printer?
A 3D DLP printer uses a liquid photopolymer resin that has the ability to solidify when exposed to a light source. A 3D DLP printer is a form of vat polymerization. SLA and DLP are both very popular options when it comes to vat polymerization 3D printing. Of course, both types use resin and require a light source for 3D printing but the difference lies in the type of light used by the two. To understand how a 3D DLP printer works, one must understand how SLA, the predecessor to a 3D DLP printer works. 3D printers that use SLA make use of a build platform, light source, resin filled tank and galvanometers.
An SLA 3D printer works by putting the build platform into a tank that has the resin. Only a layer of height is kept between this build platform and the tank’s bottom. After this stage is over, the galvanometers direct the laser beam to a point that indicates a single layer of a component. A galvanometer is a mirror like component that assists in directing the laser beam of the printer to the bottom of the tank. The laser solidifies the resin and makes the indicated region a solid layer. When a single layer is completed, the laser moves to the next layer and the cycle is repeated until the component is finished.
A 3D DLP Printer works much differently.
How does a DLP Based 3D Printer work?
Now that SLA has been explained, the workings of a DLP based 3D Printer can be explained. A DLP Based 3D Printer is considered a sister technology to the former and the only difference is the light source used for the solidification of the resin. A DLP Based 3D Printer uses a light that is actually a digital light projector screen. Due to the difference in light sources, a DLP Based 3D Printer is much faster than other forms of 3D printing.
Benefits of a High resolution DLP 3D Printer over an SLA printer
A High resolution DLP 3D Printer has many advantages over an SLA printer. In the latter, the printer’s laser must individually solidify the resin in a point to point method. However, with a DLP printer, the projector screen displays the complete image of the layer instantly so that all the points of a layer can be solidified immediately. Due to this, the printing speed of a DLP printer is vastly superior to SLA printing.
DLP uses digital technology and the 2D image projected is made of pixels. When this is turned into a 3D image, the pixels turn into voxels. The light source within a DLP 3D printer is a LED screen but it does not mean much if it lacks a DMD, digital micromirror device, which the heart of every DLP printer. A digital micromirror device holds thousands, sometimes millions, of other little micromirrors that direct where the light should shine to and creates the layer pattern on the bottom of the tank. The resolution of the printed component is dependent upon the number of micromirrors in the digital micromirror device.
Desktop DLP 3D Printer
A Desktop DLP 3D Printer develops highly accurate final results, is compatible with a range of materials and is extremely fast. While these machines once cost too much, recent development in technology has made Desktop DLP 3D Printer a much more affordable option today.
DLP 3D Printer for Jewelry
The advantages of a DLP 3D printer makes it well suited for the jewelry manufacturing industry. To cater to the needs of the industry, one can find specifically designed DLP 3D Printer for Jewelry. A DLP 3D Printer for Jewelry prioritizes durability, fast printing speeds, ease of handling and high precision. They are capable of fine resolutions but within a smaller build volume. This will of course, not be a problem for a jeweler since the sizing they work with are of a smaller size.
DLP 3D Printer Resin
A 3D DLP Printer resin is one of the best resin printing options for those looking for excellent and rapid 3D printing. While it was once restricted to a niche market, they are now very popular in a range of industries as well as hobbyists interested in 3D printing.
What is a DLP 3D Printer?
A DLP 3D is a 3D printer. What makes it unique is that it utilizes a DLP, digital light projector, as the light source to solidify photo-reactive polymers. A DLP 3D printer has many advantages over convention 3D printing and even SLA. One key benefit over SLA is that DLP requires just a shallow tank of resin for the process. This reduces wastage during the process and lowers the cost of the process.
How does a DLP 3D Printer work?
The DLP 3D printer process works by utilizing the projector. The projector solidifies the resin, one layer at a time. The entire layer that the projector shines on is cured instantly, which is why these printers are extremely fast. When a layer is finished, the resin part is pulled by the height of about a layer and process repeats all over again.
