Ultimaker 2
Ultimaker 2 Modified
Current:
- Ultimaker 2 ... bought immediately after release, sometime near 2013. Also today 2018 it is still my very first and only 3D printer in top condition with almost daily use.
- The use of biopolymers as the only printing material is important to me.
- The machine is modified, similar to the later released Ultimaker 2+
- I use dual-head with currently 0.4 / 04mm stainless steel nozzles. The main purpose of the second nozzle at the moment is solely to create a thin first PLA layer as an ideal primer for problematic adhering HT-PLA.
- The unfortunately extremely poor original Ultimaker material feeders were replaced very early by a self-constructed material feeder with similar functionality, which I used a few years satisfied. Now I use 2 pieces Bondtech QRv3 Universal Dual Drive extruder with geared stepper motors.
- A X-Vision from AeroCool efficiently cools the motherboard and all stepper motors. This keeps the machine in a moderate temperature range during the entire operating time.
- I have modified the design of the original engine covers so that passive ventilation is guaranteed, and if needed 40mm fans can be used for active cooling. For example, I use a semi-transparent filament for the motor covers as a small side effect and LED strips are fixed inside, so you can look a bit through the walls :-)
