Our unique 3D printing technology

Inventors of LCD 3D printing

3D printing technology has come a long way since the initial days of rapid prototyping back in the 80s, and Photocentric are leading the way in 3D innovation, through our patented LCD printing technology.

LCD is a quicker and more cost-effective way for businesses to mass produce.

What is 3D printing?

In simple terms, 3D printing is the process of creating a three-dimensional solid object from a digital file.

3D printing or Additive Manufacturing, allows 3D printed objects objects to be built up via successive material layers, until the desired shape is formed.

The individual layers are finely sliced cross sections of the overall object, and complex shapes can be created quickly and efficiently.

Due to the additive manufacturing process, less materials are used than the traditional methods, as is the opposite of subtractive manufacturing, where objects are hollowed out of a block of material.

To appreciate the benefits of our patented LCD print technology, it is important to understand the differences between the other 3D printing technology methods.


The concept we invented. Using an LCD screen as a light source, an entire layer is flashed at once, rather than one single point. LCD printing is a quicker alternative to other methods.

Our LCD 3D printing technology is enabling customers to create, cast and customise new products at a rate previously unimaginable.


Invented in the 1980s, SLA was the first 3D printing technology in the world. SLA uses a laser to cure liquid resin into hardened plastic, via a process called photopolymerization.

Popular for their detailed output and ability to produce highly accurate parts, they can be time consuming compared to LCD printing.


FDM followed shortly after SLA and is the term for a form of 3D printing where parts are produced layer by layer, with this process, the resolution of the part is determined by the extruder nozzle.

This method can lead to voids and visible differences between each layer and lacks the accuracy of the LCD printing technique


Similar to LCD technology, DLP projectors create an image of an entire layer. However, the techniques differ as DLP works by shining light through a lens to a DMD, which must then direct the light to the bottom of the resin tank.

The hardware involved is much more costly than LCD. Bulbs need replacing and the print quality is less defined.

Masters of light

With our earliest granted visible light patent stretching back to Jan 2005 (GB2422678) and numerous subsequent 3D patents granted using LCD screens and Daylight we are the undisputed world leaders in both LCD 3D printing and visible light polymerisation.

Daylight 3D Printing is far better for screen life, lower in energy usage and safer, but it also makes printing more reliable, delivering a more even cure than higher intensity UV with its greater depth of penetration. It is much more effective to use daylight with dark coloured or particle rich formulations as the longer wavelength travels further.

LCD printing explained

1) LED light source

Photocentric’s LCD printers use an array of LEDs as a light source, shining parallelly direct on to the build area. As an entire layer is flashed at once, rather than one single point, LCD printing is a quicker alternative to other methods.

2) Slice image on screen

The LCD screen only lets the light enter where it is to be cured for the finished part. This method simplifies the process and removes the need for other materials, such as mirrors or galvanometers.

3) Daylight resin cures

LCD 3D printers use our unique daylight liquid resin which instantly hardens into plastic as it is exposed to LED light via an LCD screen. Powerful LCD panels shine lights via LEDs at the model, the LCD panel then blocks off areas that are not to be solidified.

4) Printing by layers

Photocentric printers produce “bottom-up” print, where the object being printed is pulled out of the resin and returns to one layer higher than the previous after each layer is cured. The process is repeated layer by layer until the shape is built.

Advantages of LCD 3D printers

Increased accuracy

Prints are more accurate, reducing the costs of reprints and print fails.

Faster printing

LCD printing is a far quicker alternative as complete layers are printed at once.

Cost effective

LCD screens offer the most cost effective and reliable device on the market.

Longer product life

LCD screens last longer than lasers or bulbs used in other 3D printers.
