We previously introduced ColorFabb's new material, "nGEN," from the Netherlands. It boasts better toughness and temperature resistance than PLA, without the warping and shrinkage issues common with ABS.
I immediately decided to print the long-dormant engine model! This time, I printed two components of the 22RE four-cylinder engine: the engine block and the timing cover.
This is a very interesting and cool model, completely reverse-engineered from a Toyota 22RE four-cylinder engine.
Aside from a few bearings and fasteners, most of the parts are made using 3D printing. Let's take a look at the finished prints below!

Printing Parameters:
Printer used: Ultimaker 2+
Slicing software: Cura 15.04.4
Material used: Colorfabb - NGen - Dark Grey
Nozzle diameter: 0.4mm
Layer height: 0.15mm
Printing temperature: 230C
Printing speed: 40mm/s
Infill density: 25%
Support: Enabled (30% fill amount, 0.15mm Z distance)
Printing time:
Engine block: Approximately 43 hours
Timing cover: Approximately 30 hours

The glass transition temperature of nGEN material is 85 degrees Celsius, and its strength has also been improved. Printing complex objects like engines presents no problems!

nGEN has excellent color saturation and a strong reflective quality, making it very beautiful and eye-catching!

Many small holes on the engine block maintain their perfect circularity even without support!

The timing cover can also be easily completed, but the engine alone took 43 hours, and the timing cover took 30 hours. So, if you don't have a reliable machine, it could be quite frustrating!

Once all parts are printed, there's still the assembly. Therefore, both the machine and the material itself must have excellent stability!

The surface after support removal is also quite neat, without too many severe imperfections!
