3DMART also brings you great news! Until Christmas 2015, every Ultimaker 2 and Ultimaker 2 Extended you purchase will come with a free Olsson Block: https://3dmart.com.tw/tw/news/show.aspx?num=39
Dr. Daniel J. Thomas's turbine intake jet engine model can be found here: http://www.thingiverse.com/thing:589668
Today's machine is the Ultimaker 2 Extended, which maintains the same high quality as the Ultimaker 2, but with an increased print height of 30.5 cm!
And the star of the show is the 0.25mm Olsson Block. The complete Olsson Block set comes with 4 different nozzle sizes (0.25, 0.4, 0.6, 0.8mm).
Once the Olsson Block is installed, the printhead can be changed quickly like this!
The 0.25mm nozzle is perfect for parts that require finer details, such as turbine blades!
Zooming in, you can see the intricate detail of each small blade.
After a while, the blade part is printed~
Starting to print the base. The base also has some relatively small internal structures.
The base has also been successfully printed~
Assemble all the parts~ Ta-da! The jet engine is complete!
The filament used is Ultimaker's silver PLA. All parts combined took 71 hours and 18 minutes to print, weighing a total of 236 grams.
