This was one of the top 10 China scientific development in 2011 has made the headline of scientific / industrial news last year:
China develops the world’s largest selective Laser Sintering equipment
Dec.8, 2011
Huazhong University of Science and Technology research team in China has successfully developed a selective Laser Sintering machine with build volume of 1200mm x 1200mm. Currently the big players in the laser sintering machine market are EOS from Germany and 3D systems from US. EOSINT P730 Plastic laser-sintering system has an effective build volume of 730 x 380 x 580 mm (27.6 x 15 x 22.9 in.) and 3D Systems' sPro™ has the build volume of 550 x 550 x 750 mm (22 x 22 x 30 in.). Therefore this is at the moment the largest laser sintering system available on the market.
The selective Laser Sintering technology can shorten the development cycle from months to weeks. It can be used in manufacturing power equipment, aerospace, automotive and other high-end products, such as hollow turbine blades, turbine disks, engine exhaust, engine block and cylinder head etc.
In 2010 the team was selected by Airbus to support producing large-scale titanium alloy structural parts for aerospace. It is reported that they have already got 200 orders for this system.
Here are some photo examples showing the products from the technology.
photo 1. PS Wax mold of Aluminum gearbox for tank engines
photo 2. A large thin-walled mold with size 847.92 x 185.46 x 229.90mm, building time is 29.3 hours. The accuracy is 200+-0.2mm, minimal wall thickness is 3.3mm.
Below are another three products they have made for customers:
1. Aluminum door frame wax mold for planes: size: 1020.27 x 109.98 x 113.26mm. Building time: 10.5 hours
2. A large titanium thin-walled mold for satellite: size: 660mm x 660mm x 760mm, accuracy 0.1%, building time: 72 hours
3. A titanium frame wax mold for satellite: size: 750mm x 750mm x 764mm, accuracy 0.1%, building time: 54 hours
