We previously introduced ColorFabb's new material from the Netherlands, "nGEN", which boasts better toughness and temperature resistance than PLA, without the warping and shrinking issues of ABS.
I immediately decided to print the long-shelved engine! 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:
Machine 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
Print Speed: 40mm/s
Infill Density: 25%
Support: Enabled (30% fill amount, 0.15mm Z distance)
Print Time:
Engine Block: Approximately 43 hours
Timing Cover: Approximately 30 hours
nGEN material has a glass transition temperature of 85 degrees and improved strength, making it perfect for printing complex objects like engines without any issues!
nGEN has excellent color saturation and a very reflective finish, making it beautiful and eye-catching!
Many small holes on the engine block maintain their perfect circularity even without supports!
The timing cover can also be completed easily, but printing just the engine took 43 hours, and the timing cover took 30 hours. So, if you don't have a reliable machine, it could be quite frustrating!
After all printing is done, there's still the assembly issue, so both the machine and the material itself need to have excellent stability!
The surface where supports were removed is also very neat, without too many severe rough spots!
Let's take a quick look at how the fully assembled 22RE four-cylinder engine works!
