UV curing system market size - Split by application
UV CURING - INTRODUCTION
• In a global way, inks hold the hot spot for UV curing
• This is likely to continue in the future, as:
• The adhesive market is much smaller in terms of market volume/size.
• Coating applications still suffer from technological challenges (i.e. surface finishing) with UV curing.
Many different applications with various UV light requirements.
Inks represent the main market for UV curing systems (~68%).

• Due to the difference of output and efficiency between mercury lamps and UVC LEDs, the main challenge is to increase the overall systemefficiency.This can be done by designing a highly efficient reactor to compensate the low efficiency of UV LEDs.
• Today, there are a few players offering UV LED treatment systems. Each product has a different reactor design but they all have incommon a highly efficient reactor design.

• To ensure a long LED lifetime, a special care must be dedicated to thermal management of LEDs. If high temperature is applied on aLED, its UV output will decrease over time and therefore reduce disinfection efficiency.

• CLIP (continuous liquid interface production technology) operates through photo polymerization. CLIP “grows” objects, rather than building themin layers.
• Traditional 3D-Printing requires a number of mechanical steps, repeated over and over again in a layer-by-layer approach. CLIP is a chemicalprocess that balances light and oxygen to eliminate the mechanical steps and the layers.
• It works by projecting light through an oxygen-permeable window into a reservoir of UV curable resin. The build platform lifts continuously as theobject is grown. It is 25-100 times faster than traditional 3D-printing technologies.
• This technology uses UV LEDs at a wavelength of 395nm.

Time evolution of patent publications - Overview
UV LED INTELLECTUAL PROPERTY LANDSCAPE
Remark:There is typically a 12-18 months delay between the
moment a inventor files for a patent and the moment it is
published and becomes visible to the public. This explain why
patent publication seems to be decreasing in 2017 Artificial
decrease due some patents being not yet visible.
Since 2000, there have been growing level of
patent publications related to UV LED: From
~XX in 2000 to ~XX in 2016 (42.5x).
