DLP (Digital Light Processing)
DLP or Digital Light Processing is a 3-dimensional printing method. Just like stereolithography, it uses photopolymers. DLP produces parts with high accuracy and resolution.
However, it is different than stereolithography. Digital light processing employs a traditional light source such as an arc lamp that has a display panel as well. It is faster than stereolithography because it is used with the entire surface of the vat of the photopolymer resin in a single pass. However, DLP uses only a shallow vat of resin which lowers the running costs and levels of waste.
How does work DLP?
Digital light processing enjoys many advantages over other techniques. First, its high printing speed is exceptional. This is one of the most major differences between DLP and SL. A 3D file that is printing in 4 hours with the SL technology can be completed in half an hour with DLP.
Another pro of DLP is that it lets curing the whole surface of the layer at once. So, there is no need for post-curing.
There are many applications of DLP. It can easily produce patterns that will be used for investment casting. It can also make master copies for vacuum casting.
Furthermore, digital light processing is one of the best 3D printing methods available for designing models with complex and intricate geometries. So, it is a popular method in designing jewelry and helps in dental procedures.
Another useful application of DLP is its use in producing functional testing prototypes. It can be used for making visual prototypes needed for market testing.
Minimum Layer height are 0.03mm. Accuracy dependent (+- 0.01mm). Tolerances are vary 0.5%(+/-)
We are strongly advised that 3d printed part can be supported required therefore post process will be required.
