3D print complex elastic lattice structure

Headquartered in Germany 3D print service provider Rapid Product Manufacturing (RPM) announced on June 15, 2021, announced its research funding, developing complex elastic lattice structures, funded by German AIF. Using Carbon Resin Digital Light Synthesis (DLS) 3D printing technology and EPU41 / EPU40 materials, RPM plans to develop a variety of applications for these lattice structures for their partners in the industry next year. The project will also be supported by the Micro Technology Institute of the NPRK Technology.

3D printing new application

RPM adopts DLS technology in 2018, enabling the company to become one of the first batch of Cabon 3D technology in Europe. RPM believes that printing speed and high resolution capability is the main factor in meeting customer needs. In 2020, RPM produced more application series components compared to DLS prototypes, marking the transformation of technology. RPM plans to focus on establishing a 3D print lattice material, design rules and application knowledge base in the next few years, and become manufacturing leaders in this field. In addition, RPM will also use Carbon's automatic lattice generating tool Design Engine to continue to explore 3D print lattice structures.

Dr. Claus Thomy, Sales Medicine, Sales Medicine, said: "This gift is over DLS, because Carbon places mass production at the forefront. The material selection and reliability of the machine process allows us to cover each with competitive cost point. A new business. More importantly, due to the standardization and verification, the second, the third and twentieth printing methods are exactly the same. "He added:" When RPM is only adding only When the lattice structure available in the manufacturing is improved, we are building truly excellent product solutions. "

The Zim project is awarded by AIF (Arbeitsgemeinschaft Industrieller ForschungsvereiniGungen) to support research and development of German medium-sized enterprises. The official subsidy name is "Developing a variety of applications to develop elastic lattice structures by adding materials", and supports the development and technology of Micro-Technological Research in the University of Lemrace.

RPM will optimize the process parameters of mass production by mechanical and performance testing through mechanical and performance testing, production and evaluation of various geometric shapes. Studies have also chosen six applications, expand production knowledge:

Directional cooling passage (proactive and passive) in liner structure

Pneumatic control mechanical function

Liquid control mechanical function

Cool and heat in the elastic parts

Damping characteristics with air and liquid

Integration of Flow System in Elastic Parts

R & D stages are critical to solving component performance, user experience, and cost optimization, so that the entire product life cycle is qualified. RPM is expected to have multiple demonstration models and process parameters after completion of the spring project in 2022, and lay the foundation for industry products.

Advantages of lattice structure

Although from the perspective of production and mechanical performance, researchers in many fields still have expectations to improve product functions in the elastic grid. According to Carbon, reduce the amount of material usage by selecting a grid to reduce the amount of 57%, and the construction time is reduced by up to 54%, while maintaining the performance of the part. This can save a lot of time and cost for manufacturers.

Dr. J RG Gerken, general manager of RPM Technology: "DLP technology enables us to use different methods for product and parts design. RPM recognizes that from the perspective of technology and materials, the lattice will continue to be critical applications. After using rules and irregular dot matrix in EPU materials, we have prepared to build next-generation production. This grant provides us with the necessary R & D and preparing for fast product manufacturing to prepare for additional fuel needed. "

Lattice application

It is understood that the lattice structure has been studied and applied in many fields. California Institute of Technology Prints lithium battery electrodes with lattice structure 3D. Engineering Software Developers Coretechnologie Update 4D_Additive Print Preparation Update 4D_ADDitive Print Preparation Using Auto Lattice Generation Module. The software's dot matrix tool enables users to print various types of internal and external grid structures, such as honeycombs, gyro and stars.

University researchers in Glasgow have found that 3D printing mixed plastic - carbon nanotube mixed materials can be applied to lighter, more resistant to impact, and cleaner automotive manufacturing. There will be more lattice structures in the future, let us wait and see!
