 Industry research in application technology

Many Chinese 3D printing companies are involved in industry research on application technology and part design. We selected a range of technically advanced and internationally competitive examples of their developments.

Application technology: Complex thin-walled or lightweight parts for Aerospace

One of the challenges in metal printing is toapply selective laser melting technology for manufacturing large and complex thin-walled parts. Stress, deformation and metallurgical defects are the major factors that plague the industry when it comes tothose parts.Xi’an Bright Laser has made series of breakthrough application developments in this area. Typical parts are:

A minimum wall thickness of only 0.3mm has been achieved. The successful completion of the blade edge has proven that Xi’an Bright Laser achieved a new level in application technology. To achieve such results, it is necessary to understand the material, the process and to have the appropriate quality of machinery in place. The leaf ring was manufactured by 4 lasers simultaneously, which is another example howthe company handled the challenge of cracking, a problem with all 3D printed large thin-walled components.

The China Academy of Space Technology has gainedmany years of experience in 3D printing, especially regarding design for additive manufacturing (DfAM).The academy has developed a systematic approach for the study of lattice cell structures for lightweight satellite components, and with this has achieved to be internationally competitive in this field.

The material has been widely applied in more than 30 countries on tens of thousands of cases, and is considered as the dura mater (ridge) membrane closest to a patient’s autologous cells with the best repair effect.

China’s 3D printing industry’s road ahead – Bridging the gap

Currently the Chinese market is still lacking regarding industrialized applicationsthat could compare to iconic achievement such as the 3D printed fuel nozzle of GE, the Adidas shoe middle sole, and Siemens’ turbine blade. However, China has developed its own strengths in 3D printing technology and applications, which we hope we were able to highlight. Those achievements and most importantly future developments are further fueled bygovernmental support to this industry. The Chinese 3D printing industryhas gained attentionacross the countryis starting to attract investors worldwide, which is testament to its potential.

We see a lot of room for improvement to catch up to the trend of industrialization of 3D printing as on international level. One key point is the connection of the 3D printing and manufacturing industries – an issue that applies globally. Still, it seems especially difficult for 3D printing companies in China to reach out to the local manufacturing industry. In China today,relatively few companies are aware of the power of 3D printing and the Chinese market lacks the openness and the understanding for the role this technology can play. This is because till recently, China focused on low value added manufacturing, while this is not the strength of 3D printing. Though this is clearly changing, this heritage created a gap which is very noticeable today and probably reason for the high export shares in revenue for many Chinese 3D printing companies.

Essentially, the manufacturing industry of China will need to understand the power if 3D printing to create manufacturing and product life cycle value as they upgrade from a low to a high(er) value added manufacturing philosophy. Bridging the gap will be key for the 3D printing industry to reach maturity and scale in China.
