The Danish start-up company Blueprinter ApS is about to hit the world 3D printing market with a patent SHS™ (selective heat sintering) technology.
This innovative Danish enterprise was set up in 2009 aiming to create a kind of "office 3D printer" with affordable price and high printing quality.
Their patent SHS™ (selective heat sintering) 3D printing technology was launched at Euromold in 2011. It is similar to laser sintering, but instead of using a laser SHS uses a thermal printhead. The powder bed is held at an elevated temperature so the mechanically-scanned head only has to elevate the temperature slightly above the powder's melting temperature to selectively bond it.
How does it work? A 3D model is designed in a CAD software then it is sliced into layers using another program. When the "print" button is pressed, the printer spreads plastic powder in a thin layer across the build chamber. The thermal printhead starts to move back and forth, and heat from the printhead melts each cross section into the plastic powder layer. Again the 3D printer prepares new layers of plastic powder, and the thermal printhead continues to apply heat onto layers of powder. Eventually the 3D model is made in the build chamber - surrounded by unmelted powder. Unused powder is 100% recyclable and there is no need for additional support materials.
With selective heat sintering technology the 3D printer can make the forming of any complex geometry(minimum wall thickness is 1 mm). Multiple 3D models can be loaded and printed at the same time.
Build chamber (mm): 160 x 200 x 140 (W x L x H)
Printing speed: 10 mm/hour
Layer thickness: 0.1 mm
File formats: STL
Printer dimensions (cm): 100 x 60 x 60 (W x L x H)
The introduction price of Blueprinter's SHS 3D printer is €9,995, and the material costs €49 per kilogram. It is expected to launch in the first half of 2012. Pre-order is possible via their website www.blueprinter.dk.
"Our target group includes engineers and designers in the small and medium-sized segment, as well as engineering and design departments in large organizations." said Mr. Torben B. Lange, CEO of Blueprinter. "We are currently focusing on gaining a foothold in the market and establishing business contacts all throughout Europe. We are now at the lookout for distributors and resellers who are prepared to sell our printers in their respective markets and to offer excellent customer service and support."
