It is a masking screen (Monochrome) which nowadays has been widely used in the resin printing industry. But why?
Frankly, there are dozens of reasons which are appurtenant to the printer itself.
By using Monochrome LCD screens, a printer can use much less energy than the normal RGB ones although there is no need for regular maintenance as such.
One of the key benefits of them is about time. They are known for their faster printing process than the color screens. Maybe you say, “OK, there is no much difference between them”, But without a doubt, regarding extremely large files, the printing speed is of paramount importance. Once you know the fact that they are somehow about two times faster than the regular RGB ones, you may be evinced by a burning desire to take a look at them.
By using Monochrome LCD screens, the process could be done with a remarkably swift cure time. Thus, the super speedy cure times induces faster print time.
Additionally, the exposure time could be significantly decreased. In other words, the process can achieve layer cure times of a very few seconds which allows for much faster exposure settings. As mentioned, these screens allow for very short layer exposure times. Hence this leads to a huge time reduction; roughly one quarter of the time which is needed for RGB screens.
Monochrome LCD screens have much longer lifespan than the normal color ones. It is worth mentioning with proper use they can last several thousand hours. Because of that, they have stable performance during long term printing. It is said that they are four times longer in lifespan than the others.
You need to select “Non-Standard Monochrome” on “
Setup > Machine Settings > Display Controller > Non-Standard Monochrome” to use monochrome display on NanoDLP.
– Keep in mind unnecessarily high exposure time settings can also shorten the life of a Monochrome LCD screen.
– Keep In mind these screens have a higher cost than the normal RGB ones due to their smaller inventory.
Conclusion (Monochrome vs RGB)
+ Printer uses less energy
+ Faster printing; double times
+ Reduce exposure time; one quarter
+ Longer life span; four times
+ Faster cure time
– Higher cost
As a matter of fact, Monochrome LCD screens could significantly enhance the printing efficiency which leads to more stable performance for the entire printing process.
NanoDLP Display Engines
NanoDLP supports many way to display images, this post try to explain how each one works, what is the best and also give workaround for cases which one engine does not work well enough.
NanoDLP Folder Structure
Knowing NanoDLP folder structure could be useful for many cases. This post mostly focused on Raspberry Pi installation but also cover other OSes too.
NanoDLP shield is a low cost simple PCB board with stepper driver, which directly get wired to Raspberry Pi GPIO. Without any additional hardware you can control all elements of basic SLA/LCD 3D printer using this board.
