ADDIREEN Unveils Green Laser Metal 3D Printing Solutions at Formnext 2024, Germany

From November 19 to 22, 2024, the Formnext exhibition—a premier global event for precision forming and 3D printing—was held successfully in Frankfurt, Germany.Shenzhen ADDIREEN Manufacturing Technology Co., Ltd. （ADDIREEN）（希禾增材）made a stunning appearance with its self-developed green laser metal 3D printing equipment and a series of innovative solutions, showcasing the company’s latest breakthroughs in the field of green laser printing. With a focus on precision, efficiency, and sustainability, ADDIREEN captivated a global audience through its multi-industry applications and live demonstrations.

Technological Advancements

Revolutionizing Green Laser Advantages

In the realm of metal 3D printing, high-reflectivity metals and refractory metals have long presented formidable challenges. Traditional 3D printing equipment often relies on infrared lasers as the light source. However, metals such as copper, gold, tantalum, and their alloys exhibit low absorption rates for infrared lasers, leading to excessive spatter during printing, porosity issues in the melting process, and difficulties in achieving high-density samples. These limitations constrain both the quality and performance of printed parts.

Green Laser Metal 3D Printing Solutions

ADDIREEN’s green laser printing equipment, utilizing a short-wavelength green laser source, effectively addresses many of the issues associated with traditional infrared lasers in high-reflectivity metal printing. Metals like copper, aluminum, gold, and silver exhibit significantly higher absorption rates for green laser light, enabling substantial improvements in printing precision and efficiency. Furthermore, the smaller spot size of ADDIREEN’s green laser systems makes them ideal for fabricating intricate and complex structures, meeting the rigorous demands of high-end manufacturing.

At Formnext 2024, ADDIREEN unveiled an array of impressive exhibits. One notable highlight was a rocket thrust chamber model (Photo 1), printed using either pure copper or a copper-chromium-zirconium alloy (the showcased model was made from pure copper). This model demonstrates exceptional thermal conductivity and high-temperature resistance, illustrating the application potential of ADDIREEN’s green laser printing equipment in the aerospace sector. The technology provides reliable solutions for tackling complex manufacturing challenges.

All the green laser printing equipment of ADDIREEN are "independently developed by the company", and can be customized according to different application requirements.

In addition, ADDIREEN also exhibited a variety of test pieces in the field of heat dissipation at the Formnext exhibition. The heat dissipation fin exhibition piece shown in Figure 2 adopts a hollow structure and demonstrates obvious advantages in terms of fineness and surface roughness.

Innovative Applications

Breakthroughs in Jewelry and Consumer Goods

The jewelry and consumer goods industries demand superior surface smoothness and minimal roughness in printed components. Copper, a notoriously challenging material for high-finish 3D printing, requires not only advanced equipment performance but also meticulous process control.

At Formnext 2024, ADDIREEN pleasantly surprised attendees by debuting a variety of metal decorative and consumer items. These included decorative ornaments (Photo 6: dragon sculptures with polished, silver-plated, and gold-plated finishes), copper rings, and directly printed sandblasted teaware.

Copper was selected as the primary material for these exhibits due to its metallurgical similarities to gold, particularly in laser absorption properties. After polishing and gold plating, the printed copper pieces exude a warm luster and radiant gold hue. The excellent compatibility between copper and gold ensures that even a thin gold plating layer maintains durability and an outstanding aesthetic.

These exhibits underscore the remarkable detail control of ADDIREEN’s green laser printing equipment, opening new avenues for metal 3D printing in artistic creation, jewelry design, and premium consumer products.

For example, the copper ring model in Photo 7, polished and gold-plated, rivals the craftsmanship of precious metal printing processes, exemplifying the precision and sophistication of ADDIREEN’s equipment.

Industry Leadership

Precision Structures and Extreme Testing

ADDIREEN’s green laser printing equipment demonstrates the industry’s ability to achieve a pure copper wall thickness of just 0.08mm, highlighting the company’s technological prowess in precision manufacturing. The “extreme test piece” displayed in Photo 8 offers visitors a direct understanding of the advantages of ADDIREEN’s equipment in printing high-reflectivity metals such as pure copper and its alloys. With the smallest green laser spot in the industry, ADDIREEN’s machines excel in both printing precision and intricate detail rendering, setting a robust technological benchmark.
