I am new to the world of 3D printers, so I have some doubts. I wanted to buy a printer (price around 300€) but the size is small for my purpose. the best buy for me is this: Free shipping large size metal fuselage High Quality Precision DIY 3D printer kit with LCD Ultimaker2 structure-in 3D Printers from Computer & Office on Aliexpress.com | Alibaba Group chose is because of the price. but the printing size I want is Heated Bed 30 * 30 cm and height 30/40 (height 40 if costs are not very different). They think I can build with these measures for the same price?
