Digital light processing (DLP 3D printing) uses a projector to shine light onto the photosensitive resin layer by layer to create a product. This light cures the resin in the same way that the laser does in SLA printing, but instead of a single laser, DLP printers use a digital micromirror device (DMD) to project the image onto the resin. DLP is probably the fastest resin-based 3D Printing technology currently, and it is ideal for rapid prototyping.
DLP 3D printing is widely used in a variety of applications, including prototyping, art, sculpture, jewelry making, dental and orthopedic models, surgical guides, and custom implants.
Digital light processing uses light to cure liquid resin into solid objects. Here are what we do for DLP 3D printing processes at 3DSPRO:
Import files on the DLP 3D printers.Optimize build chamber space.DLP 3D printers operating.Take the DLP 3D printed part out of the build chamber.Supports removal.Washing the resin 3D prints.UV curing resin parts.Send DLP printed parts to further post-processing (optional).Quality inspection.Packing and shipping.
1. When it comes to resin-based printing, DLP printers can print much faster than SLA printers because the entire layer is cured at once.
2. DLP produces parts with fine details and high precision, ideal for intricate designs.
3. DLP parts typically have a smooth surface finish.
1. DLP printers are often limited to using only certain types of resin.
2. DLP printed parts are generally less durable and have lower tensile strength compared to other 3D printing methods.
3. DLP prints are sensitive to UV light. They can be degraded if exposed to direct sunlight or other UV light sources for extended periods.
4. Require supports.
5. Print resolution decreases with distance from the light source, affecting the quality of larger prints.
