Reasons to Pick LCD Printing as A “Maker” Choice —Contrast Analysis between SLA, DLP, and LCD Resin 3D Printing

Reasons to Pick LCD Printing as A “Maker” Choice —Contrast Analysis between SLA, DLP, and LCD Resin 3D Printing
2021-03-31

AS A 3D printing technology started to be welcomed by current printing giants, LCD printing is not the first resin printing solution that came into the application.

 

It was SLA that went mainstream as the first generation more than 30 years ago when resin 3D printing started to strike a blow.

 

More than 10 years later, DLP printing followed its step.

 

Relatively, LCD is a printing method created in 2013, from its first product of commercial use in 2014, it's run for only 7 years.

 

As we know, SLA adopts the 355nm or 405nm ultraviolet laser as the light source and uses the galvo system to control laser spot scanning, wherever the laser has spotted will be cured, but the most patented feature is its curing process is from point to surface because laser projection is a spot. Given this is a point molding method, its molding process will be not be completed so quickly. But the most obvious disadvantage happens to be its pronounced strength: Point molding can not be finished in a short time, but the molding size is unlimited, which means this technology can be applied in industrial areas and models of large size. 

 

Relatively, DLP is faster than the other two printing methods. It is abbreviated from “Digital Light Processing,” which means it is a 405nm light projected through the micromirror device—a technological device developed by a company named TI of America(who owns this technology only until now)—after digital processing.

 

The most marked difference between it and SLA is that it is a surface curing through this mirror projection, which means DLP molding is a printing process layer by layer, or more exactly, icey layer by layer. This not only ensures the printing precision, but also greatly improves its printing efficiency and stability, and here is what renders its superiority in the printing of dental care and jewelry models manufacturing. It is just its dominant market ownership that determines its costly price for model users to apply.

 

As a newly disruptive technology in this century, to markedly differentiates itself, LCD embraces many virtues, but the most impressing one is its cost down compared to its two previous predecessors.

 

LCD resin 3D printing is a technology that adopts the LCD screen to project the high power LED light of 405nm wavelength, the same with DLP. Since the projecting intermediary is an LCD screen, the projection area is limited, it depends on the size of the screen. A screen of what size will mold a maximum model of what size.

 

Molding tech. Molding method Printing  precision Wavelength Light source projection Application
SLA Point stereotyping 100μm 355 or 405nm Galvo system Industrial models
DLP Surface stereotyping 50μm 405nm Digital projection Dental care/jewelry
LCD Surface stereotyping

50μm

(Black-and-white screen)

Owing to all these reasons, it brings to all these different applications of these three technologies.

 

SLA is molding technology that embraces size but not speeds, and it is one that can be widely used in industry. But DLP is an imaginably good choice of high precision with probably the right size, but the price embraces those who can afford it.

 

LCD resin 3D printing, as a newly emerged successor, improve the printing speed by a layer printing method and cut off the high price caused by TI monopoly, but its main component of the LCD screen is its most vulnerable part because of the strong projection of LED light including ultraviolet rays, which is not only hot but also strong. So the maximum service life is normally about 2000 hours for the current black-and-white screen LCD printer of Creality if no other abnormal operation is processed. 

 

Despite this defect, it’s not hard to tell that, it is still the best choice for a maker to choose LCD resin 3D printer as their creative applications given all its merits.

 

Creality always has been endeavored to provide its users with practicable and cost-effective products for those who want to improve their lives and translate creativities into reality. Here it’s the most popular resin 3D printer of Creality now, you can find its link below, welcome to bring such a “printing magician” to your home, providing both your life and your study one more useful hand.
