For my final project in high school I designed and built a 3D printer. With the printer I wanted to be able to print an A4 cuboid (297 x 210 x 210 mm WxDxH).
The only prior printer I had seen in real life was the Ultimaker 2. I really appreciated its motion system, my design uses a similar motion system and enclosed design.
After a year I updated the model and rebuilt the printer.
Large build volume
The printer runs on a WiFi connected
mini computer. It has a touchscreen for easy control.
Enclosed print area
Airflow cools the electronics. The heated air is then sent into the print area.
Cartesian mechanical system
Space efficient, simpler motion, and low moving weight.
Fully supported hotend
Only one tool needed to swap nozzles. No risk of bending the heatbreak.
Build volume: 295 x 195 x 210 mm 11.6 x 7.67 x 8.27 in (W x D x H)
Print speed: 40mm/s
Max print speed: 120mm/s
Print resolution Z-axis: 25µm
Max print temperature: 250°C
Max heated-bed temperature: 90°C
