What Is DLP 3D Printing?

Digital Light Processing (DLP) is an advanced 3D printing technology that utilizes the properties of liquid photosensitive polymers, which cure when exposed to specific light. In Digital Light Processing(DLP) , a digital light source precisely projects light onto the surface of the liquid photosensitive resin, curing it layer by layer to form the final object parts

DLP technology emerged more than a decade after Stereolithography (SLA) and is recognized as the second generation of light-curing molding technology. While both DLP and SLA rely on light cured liquid polymers, Digital Light Processing (DLP) uses a high-resolution digital light projector to precisely control light projection. This allows for detailed and efficient layer-by-layer curing of the liquid polymer. As a result, DLP technology is highly valued in the 3D printing industry for its precision and efficiency.

DLP 3D Printing Process

1. First, slice the 3D model using slicing software and display the slices using a projector. Each layer of the image is cured in a thin resin layer by a photopolymerization reaction to form a thin layer of the part

2. Then, the build platform moves to the next layer (this can be done in two different ways: upward or downward). The projector then displays the next slice, and the process continues for the subsequent layer.

3. This cycle repeats until the printing is complete.

4. After printing, remove the parts from the platform using a spatula. Clean the parts with anhydrous ethanol, and then perform post-curing to finalize the process.

Advantages Of DLP 3D Printing

Subtitle Description

Compared with other 3D printing technologies, DLP (Digital Light Processing) 3D printing equipment demonstrates significant competitiveness in the manufacturing field due to its unique advantages. By projecting tiny pixel blocks, the device achieves a dimensional accuracy of about 50μm, meeting the manufacturing needs for products with extremely high detail accuracy. This ensures machining dimensional accuracy within the precise range of 20-30μm and makes the entire machining process more efficient due to its surface projection characteristics.

The projection structure of DLP 3D printing equipment is typically integrated, resulting in a more compact layer curing molding module. This compact design reduces the overall size of the device, facilitating flexible deployment in various production environments.

The forming characteristics of DLP 3D printing equipment are mainly reflected in the following aspects:

High Curing Rate

The device operates with very high light efficiency at a 405nm wavelength, ensuring a fast curing rate and significantly improving production efficiency.

Low Cost

DLP 3D printing technology lowers manufacturing costs by optimizing the production process and material use, making the products more competitive in the market.

High Resolution

With pixel-level projection accuracy, DLP 3D printing equipment can produce products with rich details and high definition, meeting various high-precision manufacturing needs.

High Reliability

The stable performance of the equipment and the precision control system ensure the reliability of the manufacturing process, reducing the failure rate and the rate of defective products.
