3D Printing

During my vtol aircraft build, I had needed a tilting mechanism. I searched RC helicopter parts and some industrial parts. But I realized that their total weight were more than my aircraft lift capacity. I was curious about 3D printers. When I looked their prices, I saw broad range of prices from a few hundred dolars to a few tousend dolars. At the end I have ordered a DIY 3D printer set from Aliexpress. It is a RepRap Prusa I3 based 3D printer and it has following specifications. Model: 3DCSTAR P802MA_v1.9 Auto Leveling Control Board: Melzi v2.0 Interface Type: USB Structure Material: Full acylic and metal Filament Diameter: 1.75mm Layer thickness: 0.1-0.4mm Print speed: 40-300mm/s Filament Material: ABS & PLA HIPS PA WOOD PVA Nozzle size: 0.2mm, 0.3mm, 0.4mm support                    Max Printing Size: 220*220*240mm I paid $225 for printer and $40 for custom tax. You can see my 3D printing process as following.
