DAYLIGHT AND UV RESIN TECHNOLOGY
Since 2002 Photocentric have been at the cutting edge of innovation in Photopolymer, manufacturing a wide variety of materials that harden in light. Patent holders in visible light curing technologies, over the last 20 years they have supported and innovated a broad range of applications.
The world’s largest and most trusted manufacturer of crystal clear polymer craft stamps, delivering an ever-expanding assortment of bespoke quality craft products to customers worldwide.
Photocentric applied their understanding of UV photopolymerisation to the visible part of the spectrum, they unlocked the combination of LCD screens and 3D Printing. Patenting the daylight curing process and invented the use of LCD screens as the selective light source for a 3D printer. This innovation has won them many awards but most importantly the technology is disrupting additive manufacture industry.
The concept Photocentric 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 3D printing methods.
LCD printing is a newer method which uses an array of LCD panels as a light source shining parallelly directly on to the build area. By rapidly flashing the entire layer at once, rather than one single point, whole layers can be printed much faster.
The LCD screen only lets the light enter where it is to be cured for the finished part. It uses a series of black and white images for each layer. This method simplifies the process and removes the need for other materials, such as mirrors or galvanometers.
LCD 3D printers use Photocentric’s unique daylight liquid resin which instantly hardens into plastic as it is exposed to LED light via an LCD screen. The powerful LCD panels shine lights at the model, the LCD panel then blocks off areas that are not to be solidified through black and white images. Black blocking the light to the resin and white exposing the parts for the light to cura.
Photocentric prints in a “bottom-up” method, where the object being printed is pulled out of the resin and rises up. The process involves moving up one layer higher than the previous after each layer is cured. The process is repeated layer by layer until the shape is built.
