Case Study: Massivit 3D Printing Technologies Ltd. uses state-of-the-art Phoseon UV LED technology for 3D printing

A leader in utilizing technology to improve its products, Massivit uses Phoseon Technology’s UV LED curing to print super-size lightweight objects at remarkable speed. Massivit’s patented Gel Dispensing Printing (GDP) technology uses Dimengel, a proprietary photo polymeric acrylic gel it developed, to print large 3D objects.

Application: Why Cure Wood With UV LED Lamps?

From furniture and cabinet doors to parquet flooring, leading companies in wood manufacturing are embracing UV LED curing for wood coatings for several reasons, but mostly because it’s cool. Literally.

Phoseon Technology’s revolutionary UV LED curing raises work piece surface temperature less than half of traditional curing methods that utilize traditional UV or arc lights, which can heat the wood’s surface by as much as 60 degrees Celsius.

Whether curing the b-stage or gel fillers, or hardening the surface coating, wood products can typically pass through as many as 10 UV curing stations during the finishing process. The extensive heat created by multiple curing stations utilizing traditional arc or microwave lamps can often damage the wood.

“Heat creates tremendous challenges in wood coating, particularly with woods with high resin or oil content, such as pine, fir, spruce and mahogany,” said Jennifer Heathcote, regional sales manager at Phoseon Technology. “Heat brings the resins and oils to the wood’s surface, and that bleeding causes discoloration and problems with coating adhesion. UV LED curing systems transfer less heat to the work surface, which eliminates these issues and creates less product waste.”

Technology: UV LED System Lifetime

The normal ‘failure mode’ of an LED is gradual degradation of the light output. Many commercial LED lighting systems define failure at 70% of the original operating output, also known as L70. Phoseon light sources are designed to ensure an L80 lifetime (80% of original output) of at least 20,000 hours, but have shown to provide L80 at as much as 60,000 hours. Figure 1 is actual data gathered by Phoseon Technology of a continuously operated light source.

Factors Affecting LED Lifetime
Two major factors that affect the lifetime of LEDs are temperature and current. As LEDs convert electricity into light, heat is created within the p-n junction, known as the junction temperature. For a diode to achieve maximum life expectancy, the junction temperature has to remain in a safe operating zone. The UV Power output of a diode increases with input current but decreases with junction temperature. At any fixed input current, the cooler the junction temperature remains, the more UV output the diode will provide.

Causes for premature LED failure include diode defects, diode packaging issues, or subjecting the LED to operating conditions outside of its specifications, in which case, it may show other failure mechanisms including rapid degradation, burned or broken metallization, or complete failure. Some lamp suppliers achieve their stated high-output irradiance by over-charging their diodes, which reduces lifetime. Unfortunately for the customer, this failure will only show up after they have purchased the inferior product and then experience curing issues.

LED Product Scalability

Increased Performance and Power

UV semiconductor devices are constructed of nearly microscopic emitters arranged in an array. These arrays are not inherently limited in shape or size. In theory any shape of size semiconductor array can be constructed. The limitation is the cost of manufacturing custom shapes compared to using standard modular shaped arrays.

These individual arrays may be positioned in any orientation and will produce uniform output. This flexibility and scalability of the technology allows SLM™ (Semiconductor Light Matrix) technology to be constructed for virtually any physical curing task without waste or inefficiency.

Semiconductor devices may be literally butted up against each other with virtually no edge effects. Using modular arrays, large surfaces can be irradiated “seamlessly” by multiple sources.

Some of the earliest UV LED commercial applications were small area adhesive and bonding applications such as medical device assembly, low-end thermal inkjet printing applications (including marking, coding and variable printing), and field repair of fiberglass composites. These early applications took advantage of UV LED’s form factor (light weight and small), through cure capabilities, and increased safety inherent with longer wavelengths. UV curing applications previously thought impossible are now possible due to UV LEDs small size, light weight, and “cool” curing capabilities.
