Digital Light Process (DLP)

What is DLP printing?

DLP printing is a 3D printing technology used to rapidly produce photopolymer parts. It's very similar to SLA with one significant difference -- where SLA machines use a laser that traces a layer, a DLP machine uses a projected light source to cure the entire layer at once.

DLP printing technology was first developed by Texas Instruments in the late 1980s. The technology has been used in a variety of applications, including in the medical field to create prosthetic implants and in the automotive industry to create prototypes.

DLP printers work by curing a photosensitive resin with a light source. The light source is typically an ultra-high-definition projector that projects an image of the layer to be printed. The projector is controlled by a computer, which tells it what to print.

The light cures the resin, and the part is then lowered into the build chamber, where the next layer is cured. This process is repeated until the part is complete.

DLP printers are typically very fast, with some machines being able to print parts in seconds. The speed of the printer depends on the size of the part being printed and the resolution of the projector.

The accuracy of DLP printers is also very high, with some machines being able to print parts with resolutions of up to 0.1mm.

DLP printers are becoming increasingly popular as they offer a fast, accurate, and cost-effective way to produce parts

DLP 3D printers are some of the most versatile and user-friendly printers on the market. They use UV light from a projector to harden liquid resins into 3D shapes through a process that converts photosensitive liquid into solid plastics layer-by-layer via photopolymerization.

This makes DLP 3D printing ideal for a wide range of applications, from creating prototypes to manufacturing small batches of parts. And because DLP 3D printers can be relatively compact and don't require large build areas, they're also well-suited for use in home and office settings.

If you're looking for a DLP 3D printer, there are a few things to keep in mind. First, you'll need to choose a printer that uses the right type of resin for your needs. There are different types of resins available that are formulated for different applications, so it's important to select the right one for your project.

You'll also need to consider the build area of the printer. This is the size of the object that the printer can create, and it's important to make sure that the printer you select can accommodate the size of the objects you want to create.

Finally, you'll need to decide on a budget. DLP 3D printers can range in price from a few hundred dollars to several thousand, so it's important to set a budget that you're comfortable with.

Once you've considered these factors, you'll be well on your way to finding the perfect DLP 3D printer for your needs.
