FuseBox is a cheap CoreXY 3D printer that uses an aluminum extrusion frame.
Contents
Goal
To design an affordable, RepRappable 3D printer using CoreXY kinematics that offers high speed and quality.
Features
- Aluminum structure based on Misumi 1515 extrusions and printed brackets
- Uses a stacked variant of CoreXY that eliminates belt crossing
- Total materials cost under $350
- 210x160x200mm build area
- Capable of 0.5mm layer height and 100 mm/s printing
- Mostly RepRappable parts and easily hackable/upgradeable
- Provision for direct and Bowden extruder setups (Bowden currently preferred due to frame rigidity issues)
- Low moving mass—all motors stationary except extruder motor in direct-drive version
- Portable—all hardware and electronics (except for filament spool) are integrated within the frame
- No specialized tools or equipment necessary for assembly
Bill of Materials
Development
Version 1.0
Initial variant. Uses a non-intersecting CoreXY design to eliminate belt crossing issues.
Issues
- Z-axis issues—slight wobble and linear bearing binding
- Slight rigidity issues caused by weak corner joints
- Extruder grip issues leading to inconsistent extrusion
- Untidy wiring
Todo
- Endstop integration (possibly with inductive z-probe)
- Cooling fan addition to improve bridging and top speed for small parts
- Bowden option for lower moving mass (will retain direct extruder for flexible materials)
- Diagonal aluminum braces on sides
- Reduce clearances for additional build area
Version 1.1
Changes'
- New compact extruder design with more solid hot end mount and fan duct addition
- Bowden extruder carriage designed; cold end still in development
- 608 bearing idler replaced by a 625 idler
- XY-gantry made more compact, resulting in ~18mm increase in maximum z-axis height
- Z axis changes: bar spacing reduced, additional reinforcement for z-nut crosspiece
Issues
- Slight z-wobble
- Rigidity
Todo
- Additional bracing
- Endstop inregration
