Atomic U300 - Big Size Ultimaker Style 3D Printer

thingiverse

I am glad to share all the design features of the ‘Atomic U300’, a 300mm Big Size Ultimaker Style 3D Printer. U in 'U300' means Ultimaker Style and 300 means 300mm build size. The design purpose of the ‘Atomic U300’ project was is to make an ‘Ultimaker’ style 3D printer with bigger printing volume and smaller machine size. So, I made design principles and objectives as follows. 1. Cost under 600$ 2. Build volume 300X300X300mm with minimum machine size 3. Utilize the most popular RepRap based parts 4. Easy to upgrade and change parts Some previous designs inspired me to start this project. • You can find all the open-source files about ‘Ultimaker 2’ on GitHub. https://github.com/Ultimaker/Ultimaker2 • In May 2015, ‘jasonatepaint’ introduced his ‘Ultimaker 2 Aluminum Extrusion Clone’ on thingiverse.com. You can check this at https://www.thingiverse.com/thing:811271 • A modified design from ‘Ultimaker 2 Aluminum Extrusion Clone’ by ‘CorrugatorSupercilii’ in December 2015 uses RAMPS 1.4 board as the main controller. https://www.thingiverse.com/thing:1178406 • ‘HyperCube Evolution’ by ‘SCOTT_3D’ introduced in April 2017 is a ‘CORE XY’ mechanism 3D printer. Although it is not an ‘Ultimaker’ style 3D printer, there are lots of useful design tips in 3D printer designs. https://www.thingiverse.com/thing:2254103 Key Features: ‘Atomic U300 3D Printer’ has key features as follows. (1) Ultimaker style XY-Axis: Crossed XY printhead linear shaft, closed-loop belt (2) Bigger build volume with smaller frame size compared to other 3d printers: 300*300*300mm printing volume with only 420*420*500 frame size (3) RAMPS-Based Fully Open-sourced Electronics: Maximizing compatibility by adopting RAMPS 1.5 board with the 12-volt power system and 12-volt heated bed and other off-the-shelf components (4) 1.75mm Filament Extruding System: Lower cost and higher compatibility (5) E3d V6 Hot-end Parts: Maximizing compatibility and low cost (6) Belt-Drive Dual Z-Axis: Providing longer moving distance and more stability of Z-Axis at the same time. (7) Z Probe Sensor & Auto-Leveling: Higher usability and easier maintenance You can check the BOM and 3d-printed parts list in the links below.
